If you are unable to transfer Android Apps to other android phone via Bluetooth or Wi-Fi then I got the solution. If you are android phone users then I’m sure that you always download android apps from Google play because it’s the only way to get best android apps on your Smartphone. But did you ever wonder to grab android app from your friend Smartphone or transfer them to your other android device via Bluetooth.
To make that thing happen you have to follow two steps in transferring android apps using Bluetooth which are listed below:
I. Downloading Required Files:
Transferring android applications via Bluetooth can be performed through the use of two applications.
- Astro (Google Play Link)
- BlueTooth Transfer. (Google Play Link)
II. How to Transfer Apps Between Android Mobiles Via Bluetooth
- Download and install Astro onto your Android phone.
- Open the Astro application. The main screen opens with a search bar on the top and three tabs underneath – locations, searches and recents.
- Navigate to “Tools -> Application Manager”.
- In the Application Manager window, Navigate to the Installed Apps tab and select the application you want to transfer via Bluetooth. Press on the “Backup” button that appears.
- The application should now be highlighted bright blue and also found in the Backed Up Apps tab. Exit out of Astro.
- Download and Install Bluetooth File Transfer app onto your Android phone.
- Open the Bluetooth File Transfer app, Navigate to the following folder “/mnt/sdcard/backups/” and select the file (with extension .apk) you want to transfer. In our case, we would find “ES File Explorer” in this location. Once the file is ticked, press the Bluetooth button.
- The android phone should be listed under “Found Devices” or “Cache”. Click the relevant android and send the file. Once the other user receives the file, he/she will then be able to install it onto their android.
- DONE

Almost
every online citizen abreast with the latest in the mobile technology
scene knows that the flavor of Android known as Jelly Bean is the latest
and the smoothest to date. But, which Jelly Bean?
Two varieties
exist for this sweet treat: Android 4.1 (which debuted with the Google
Nexus 7) and Android 4.2 (which came out with the Google Nexus 4 and the
Google Nexus 10).
Should you be gravely concerned that the phone
that you’re longing to buy runs only Android 4.1? Or, should you just go
ahead and buy an Android 4.2 device such as the Nexus 4 or Nexus 10?
Which mobile OS version is better? Is it even worth your envy to look at
another’s Android 4.2 device?
To
help you take such decision-making burden off your shoulder, we
compared pure Google Android 4.1 Jelly Bean against pure Google Android
4.2 Jelly Bean on four Nexus devices:
- Galaxy Nexus (running Android 4.1.2 build JZO54K),
- Nexus 4 (running Android 4.2.1 build JOP40D),
- Nexus 7 (running Android 4.1.2 build JZO54K), and
- Nexus 10 (running Android 4.2.1 build JOP40D).
In
this comparison, find out how the two Android versions differ, and
whether they differ greatly and significantly. You may also skip ahead
to the end of this post to watch our comparison video.
Interface
Navigation
Navigation
in both Android 4.1 and Android 4.2 remain exactly the same. On the
Nexus devices, particularly, you will find virtual Back, Home, and
Recent Apps buttons instead of physical capacitive buttons commonly
present in most other Android phones. These virtual navigation buttons
reorient themselves when switching between landscape or portrait
orientations. At times they hide as three gray dots, such as when you’re
viewing a photo, or auto-hide, as when you’re watching video.
Lockscreen
The
lockscreen layout and elements on both Android 4.1 and Android 4.2
remain mostly the same, with a few cosmetic and several significant
functional changes.
| Android 4.1 | Android 4.2 |
|
|
Switching
from Android 4.1 to Android 4.2 won’t get you a drastically revamped
and completely new lockscreen at all; rather, you’ll get the same
lockscreen with expanded functionality. You’ll still get the Clock and
the lock/unlock icon. Unlocking is still done by dropping the lock icon
over the unlock icon on the outer ring.
But,
in Android 4.2, you do get new ways to view content and launch apps
(e.g., email, SMS, calendar events, etc.) directly from the lockscreen,
thanks to lockscreen widgets.
Homescreen
There’s
not much perceptible change on the homescreen either, save for some
rearrangement in the default app shortcuts and default folders, as well
as the difference in default wallpapers.
| Android 4.1 | Android 4.2 |
|
|
The default Analog Clock widget on the main Android 4.2 homescreen has also changed, although not necessarily for the better.
Status Bar, Notifications, Toggles
| Android 4.1 | Android 4.2 |
|
|
Android
4.2 brought some new and exciting changes to the Status Bar pull-down
mechanism. The Notification Shade is still the central place for
notifications. Only very little has changed there. I didn’t see any
change in the status icons on the right side of the Status Bar either.
But,
there’s an additional Quick Settings pull-down from the Status Bar.
This new pull-down menu is also accessible via the Quick Settings button
on the upper-right corner of the Notification Shade. On phones, you can
also access Quick Settings by swiping down from the Status Bar with two
fingers.
Text Input and Keyboard
Text input on Android 4.2 is pretty much the same as in Android 4.1:
- Supports multiple languages
- Text-to-speech output usable both online and offline
- English dictionary installed as default
- Multi-language dictionaries for word suggestions
- Personal dictionary to add and save one’s own word list
- Next-word Selection feature (similar to SwiftKey)
- Voice input
But,
Android 4.2 also ushers in Gesture Typing to its stock Android
keyboard. It’s like the swipe input method which Swype is known for.
Some people actually input text faster this way than through tap-typing.
Accessibility
The two Android versions have the following accessibility features in common:
- Voice feedback
- Enlarging font size
- Auto-rotating screen
- Power button to end calls (for phones only)
- Speaking passwords
- Setting text-to-speech output
- Setting touch and hold delay
- Enhancing Web accessibility
In
addition, Android 4.2 adds a new set of accessibility features,
specifically aimed to help the blind or those with low vision. Such new
features include the following:
- Magnification Gesture — for zooming in and panning around the screen
- Explore by touch — for navigation through touch and swipe gestures coupled with voice feedback
- Accessibility Shortcut — for quickly enabling accessibility features by holding the Power button then hold down two fingers on the screen until you hear a voice confirmation.
Communication Features
Contacts
Both
Android versions still use the People app for managing and organizing
contact information. Although the People app versions differ, their
features and functions are exactly the same in both Android 4.1 and
Android 4.2:
- Backs up contacts data to Google Account
- Can also sync contacts from Google+ account
- Can store contact info locally on phone
- Has separate tabs for Groups, Individual Contacts, and Favorites; swipe to switch tabs
- Contacts can be imported, exported, or shared
- Different ringtones can be assigned to different contacts
- Contact page has shortcuts for dialing, composing SMS, or composing email
Phone
For
phone functionality, both Android versions use the stock Android Phone
app. The two versions are similar in the following ways:
- Has separate tabs for Dialer, Call Logs, and People; swipe to switch tabs
- Simple Dialer interface; tapping Dial button without entering number brings up last called number
- Dialing screen shows contact info and call control buttons (e.g., hangup, loudspeaker, mute, hold, conference call)
- Call Logs tab shows all call logs, including missed, outgoing, and incoming calls
But, Android 4.2′s Phone app is slightly different:
- Call Logs tab can be filtered to show all calls, only missed calls, only outgoing calls, or only incoming calls.
- Incoming call screen also shows Google Now shortcut (dotted circle).
Messaging
The
stock Messaging app handles sending, receiving, and managing both SMS
and MMS messages. It is usually available only on phones. Both Jelly
Bean versions retain the following similarities in their respective
stock Messaging apps:
- Displays SMS and MMS messages sent and received
- Can send messages to multiple contacts
- Character count indicator appears when message nears the 160-character SMS limit; message is split into multiple SMS if character limit is reached
- Can attach photos, videos, audio, or slideshows to MMS
- Messages displayed as conversation threads; cannot lock conversation threads
- Messages shown inside text bubble with contact’s picture beside it
- Hold down message balloon to copy, forward, lock, delete, or view details of single message
- Can auto-delete old messages when defined limit is reached (default of 500 SMS per conversation and 50 MMS per conversation); maximum limit for either SMS or MMS is 5,000
- Direct Message widget for frequently messaged contacts can be placed on homescreen
- Messaging widget on homescreen shows list of SMS and MMS messages
- Limited message deletion option: either individually or all messages at once; cannot select multiple messages/threads for deletion
The Android 4.2 Messaging app, however, has a few more new and extra goodies:
- Cell Broadcast option for receiving emergency alerts (e.g., threats to life or property, child abduction emergency bulletins, etc.), as well as test broadcasts from the Earthquake Tsunami Warning System and the Commercial Mobile Alert System
- Gesture Typing (more about this in the section on Text Input and Keyboard ((hyperlink)) section)
- Messaging widget for lockscreen; shows list of SMS or MMS messages received on lockscreen
For
email, Gmail is the default client app. And, for those who have POP3,
IMAP, and/or Exchange accounts, there’s the stock Email app for Android.
This will need some setting up, of course. Both Jelly Beans use exactly
the same version (4.1) of the stock Email app for Android.
Apps and Widgets
App
installation and management stay essentially the same in both Android
4.1 and Android 4.2. The Google Play Store, of course, is still the main
source of apps but not necessarily the only source, as one can sideload
apps from “unknown sources.”
As
in Android 4.1, app installation in Android 4.2 requires granting
permissions to the app before the device installs it. This is a security
feature in Android. I see great improvement in this mechanism in
Android 4.2, too. The permission requirements are now grouped and are
easier to understand compared to how they were in Android 4.1 or
earlier.
Android 4.2 takes security several notches higher by
including a built-in malware scanner, which scans an app for bad content
and alerts the user before app installation.
| Android 4.1 | Android 4.2 |
|
|
Android 4.1′s Clock app only has a clock function, but Android 4.2 adds two tabs for Stopwatch and Timer in its Clock app.
The
Analog Clock widget gets a different design from the Android 4.1 Analog
Clock widget. It’s not necessarily better-looking — just different.
The Digital Clock widget is new in Android 4.2. This one is not available in Android 4.1.
Web Browsing and Search
Web Browsing
Android
has finally and completely shied away from the stock Android Browser in
favor of Google Chrome, which is now the default Web browser in Android
4.2. The complete disappearance of the stock Android Browser is not all
too shocking for users of tablets such as the Nexus 7, since Chrome has
been the default browser for tablets since Android 4.1.
A
comparison between Chrome and the stock Android Browser deserves a more
in-depth article. But, to give you an overview, here are some major
feature highlights of the two browsers:
| Features | Google Chrome | Android Browser |
| Multiple tabs | more than 16 tabs | can only handle 16 tabs |
| Tab list | yes; tab thumbnails shown as deck of cards | yes; tab thumbnails shown as scrollable tiles |
| Dismissing tabs from tab list | swipe gesture or tapping on X button | swipe gesture or tapping on X button |
| Private Browsing | incognito tab | incognito tab |
| Offline Reading | preloaded content can still be accessed even if offline | saves pages for offline reading |
| Text scaling | yes | yes |
| Plugins | not supported | supported |
| Inverted rendering | none | yes |
| Reader mode | none | none |
| Syncing open tabs to or from other device (e.g., desktop, another phone) | yes | no |
| Add Bookmarks | Yes | Yes |
| Sync Bookmarks from other devices | Yes | gets synced/saved bookmarks from your Google account |
| Full screen view | none | not active on phones by default; can be toggled in Labs menu on phones; |
| Quick controls | none | not active by default; can be toggled in Labs menu; |
| Mobile version of page | yes; default | yes; default |
| Desktop version of page | yes; can be toggled | yes; can be toggled |
Search
Both
Jelly Bean versions use Google Now as the default search app. The app
integrates Google Voice Search, Google Goggles, and Google’s other
search services into just one app that shows search results on
flashcards.
You can access Google Now similarly in both Jelly Bean
versions: by tapping the Google Search bar on any homescreen or by
swiping the virtual Home button upwards from any screen.
Lockscreen
access to Google Now differs, however, in the two Jelly Beans. In
Android 4.1, quickly launch Google Now from the lockscreen by dragging
and dropping the lock icon over the Google Now icon on the outer ring.
In Android 4.2, launch Google Now from the lockscreen by swiping its
dedicated icon (dotted circle in the middle of bottom screen edge)
upwards.
Camera
The Camera
app in either of the Jelly Bean versions can be launched in the usual
way: by tapping on the Camera app on either the homescreen or in the App
Drawer.
Quick launching from the lockscreen, however, differs in
both Android 4.1 and Android 4.2. In the earlier Jelly Bean, you can
unlock the device and launch the Camera by drag-dropping the lock ring
on top of the Camera icon on the outer ring. In Android 4.2 phones,
swipe the right edge of the screen to the center to open the Camera
widget and launch the Camera. Android 4.2 tablets don’t have a camera
shortcut on the lockscreen.
If
you’re used to the Android 4.0 Ice Cream Sandwich Camera app, using the
Android 4.1 Camera app will be a similar ride: The elements and
features are similar to those in the ICS camera. The only new change in
Android 4.1′s camera is the transition effect when taking a photo and
the swipe gesture to view images taken.
In contrast, Android 4.2′s
Camera app has a simple and less-cluttered layout. Elements found here
are the camera mode options, virtual shutter button, and the circle icon
for the camera’s settings — only these three. You can also long-tap on
the viewfinder to open the camera settings menu.
| Android 4.1 | Android 4.2 |
|
|
In
addition, Android 4.2′s Camera app also has new features such as Photo
Sphere and support for HDR Mode for compatible devices. Both Camera apps
have similar camera options and effects, however, Android 4.2 decides
to get more serious by removing the Silly Faces and Background effects.
Photo and Video Gallery
Photos
Photos
captured are saved in the Gallery app. Although the two Android’s
Camera apps differ slightly from each other, most functions and features
stay similar, such as the following:
- Thumbnails sortable according to album, location, time, people, or tags
- Photo thumbnails viewable in either Grid View or Filmstrip View
- Zooming out on photo activates Filmstrip View
- Swiping image up or down deletes image in Filmstrip View
- Gallery app does not allow moving images from one album to another
- Images can be set as homescreen wallpaper
- Basic image transformations (e.g., rotate and crop) can be performed within Gallery app
- Photos can be shared via Bluetooth, Google+, Picasa, Gmail, or NFC
To
enter Filmstrip View in Android 4.1, you’d need to zoom out on an
image. Android 4.2′s Gallery app, however, provides a drop-down list to
make switching between Grid and Filmstrip Views easier.
Also, in
Android 4.2, scrolling past the leftmost photo in the Photo Viewer or in
Filmstrip View will launch the Camera app. This feature is not
available in the earlier Jelly Bean.
The built-in Photo Editor in Android 4.1 already allows you to do much to your photos:
- adjust BW balance and contrast,
- apply photo effects,
- apply color filters (Warmth, Saturation, B&W, Sepia, Negative, Tint, Duo-tone, or Doodle), and
- choose photo transformation options (Crop, Red Eye, Face Glow, Face Tan, Straighten, Rotate, Flip, or Sharpen).
But,
the Android 4.2 Photo Editor not only is easily accessible with a tap
on its icon at the corner of the screen but also allows you to do much
more:
- new filters and effects (punch, Vintage, B/W, Bleach, Instant, Latte, Blue, Litho, or X Process),
- custom frames,
- photo transformation options (Straighten, Crop, Rotate, or Mirror), and
- image colors and values adjustments (Autocolor, Exposure, Vignette, Contrast, Shadows, Vibrance, Sharpness, Curves, Hue, Saturation, and BW Filter).
Videos
Captured
or downloaded videos are stored in the Gallery app, too. They are
organized and sorted in the same manner as photos in the Gallery app.
There is only one difference between Android 4.1 and Android 4.2′s Video
Gallery: you can trim your videos right within the Gallery app in
Android 4.2. This is not possible in Android 4.1.
Media Playback
Photo Slideshow
If
you grow tired of scrolling through different pictures one-by-one, view
your photos as a slideshow. Both Android versions let you run photo
slideshows. In Android 4.1, just tap on the Slideshow button at the
upper-right corner of the Gallery app. In Android 4.2, the Slideshow
option is under Menu while viewing an album.
You can also display
your photos as a live slideshow wallpaper through the Daydream feature
that activates when the phone is charging or docked.
Playing Movies and Videos
The
Gallery app in both Android versions also doubles as a video player — a
straightforward and simple one. There is no other difference in the
video player in either Android version apart from Android 4.2′s support
for the Miracast standard, allowing wireless display sharing to
supported displays.
Playing Music
For
playing music, the default app in both Android 4.1 and Android 4.2 is
the Play Music app, which provides the following features:
- Stores downloaded songs from Google Play Store
- Songs can be copied from PC to phone/tablet via USB connection
- Songs displayed according to playlist, artist, album, songs, genres, or recently added
- Includes 5-band equalizer and equalizer presets
- Create, edit, rename, and delete playlist
- Can plays music in background
- Mini music player appears on Notification Shade and lockscreen
Security
Security features that we appreciated in Android 4.0 Ice Cream Sandwich are still present in both Jelly Beans:
- Slide, Face Unlock, Pattern, PIN, and Password lockscreen types
- Owner information displayed on the lockscreen
- Device encryption
- SIM card lock (on phones only)
- Preventing installation of apps not from Google Play Store
In
addition to those, Android 4.2 tightens security further with new or
improved security features, including the following (source: Android Developers):
- Always-on VPN
- Application verification
- Certificate Pinning
- ContentProvider default configuration
- Cryptography
- FORTIFY_SOURCE
- Improved display of Android Permissions
- init script hardening
- installd hardening
- More control of premium SMS
- Security fixes
I
greatly appreciate the application verification feature, which examines
and checks an app before it is installed, warns the user of potential
harm, and can prevent installation of the app if the potential harm is
great.
The list of Android permissions has also improved a lot.
The permissions are now displayed in groups and are described in
language that is easier to understand. A description of each permission
can also be viewed by tapping on the permission. In Android 4.1, I get a
bulleted list of a mix of technical and not-so-technical language.
Other New or Improved Features in Android 4.2
Despite
being just a minor update to Android 4.1, Android 4.2 does bring along
several features that are entirely new and not available in Android 4.1.
These include the following:
- Changes to Developer Options menu
- Multi-user feature for tablets
- Daydream
- Wireless display screencasting via Miracast
Changes to Developer Options
Unlike
in Android 4.1, the Developer Options menu is not visible in the
Android 4.2′s Settings menu by default. To activate the Developer
Options menu, tap the device’s model number 7 times to make it appear.
The Developer Options menu also has new options, such as the following:
- Take bug report
- Power menu bug reports
- Verify apps over USB
- Show hardware layers updates
- Show GPU overdraw
- Force 4x MSAA
- Simulate secondary display
- Enable OpenGL traces
Multi-user Feature for Tablets
Android
4.2 optimizes tablet functionality by allowing users to create multiple
accounts. On the lockscreen of an Android 4.2 tablet such as the Nexus
10, you will find user icons below the lock icon. Tap on the icon of the
user profile that you want to load before unlocking the tablet. If the
profile is protected by a password lock, you’ll need to enter the
password first before the tablet will unlock.
Each user account
can be personalized so users can safely download files or apps, save
images or attachments, and leave their settings without worrying about
the next user changing or viewing data.
Daydream
With
the new Daydream feature in Android 4.2, you can display the latest
Google Currents trends, a photo slideshow, a photo frame, an analog or
digital clock, or a colorful background on your device’s screen when
your device is charging or docked. It’s actually a customizable
screensaver feature. You can also manually activate it, if you want.
Wireless Display
Not
possible out of the box in Android 4.1, wireless mirroring is now
possible in Android 4.2. You can screencast your device’s display to an
HDMI device (e.g., HDTV) that supports the Miracast standard. This means
that you can wirelessly stream your slideshows, movies, videos, and the
like (your device’s display, in fact) to a supported HDTV.
Unfortunately, only the Nexus 4 has this feature.
Conclusion
So
many of the goodies that you love from Android 4.1 Jelly Bean have been
carried over to Android 4.2 Jelly Bean. Most of the stock apps and
widgets are similar in both Android versions. To the eyes, there’s no
big change in Android 4.2 at all.
But, some new significant
features and some minor alterations make Android 4.2 sweeter and fun.
Here is a brief list of new features from Android 4.2 Jelly Bean:
- Support for multiple users (for Android tablets)
- Multiple lockscreen pages with widgets
- Wireless display
- Revamped Camera app
- Photo Sphere
- HDR Mode (for supported devices)
- New Clock app
- Quick Settings pull-down menu
- Daydream
- Gesture typing
- Additional options in Developer Options
- Magnification Gestures and Explore by Touch accessibility features
- Security enhancements
- UI design changes
Placed
side by side, Android 4.2 Jelly Bean shows a slightly modified and
slightly upgraded version of Android 4.1 Jelly Bean.
Some says the Korean Manufacturer has designed this device to resemble
like Samsung Galaxy SIII or Note II, while others say it is the Samsung
Galaxy SII packed in a bigger form.
