UI differences in repackaged Android applications
The BlackBerry Runtime for Android Apps allows users to run Android applications that were repackaged for use on the BlackBerry Tablet OS and BlackBerry 10. The following information outlines the differences that you can expect to see in the UI after you repackage your application for BlackBerry Tablet OS.

Navigation |
Since the BlackBerry PlayBook tablet does not have a Back key, users must tap the Back button that appears at the bottom of the screen or use the Back gesture to display the previous screen. To use the Back gesture, users swipe from the bottom of the screen at a 45 degree angle toward the left side of the screen. Note: A navigation bar with a Back button appears at the bottom of most applications. For applications that use full screen mode (for example, games) users can swipe down from the top of the screen to display the navigation bar. |

Application menu |
Since the BlackBerry PlayBook tablet does not have a Menu key, users must swipe down from the top of the screen to display the application menu. |
|
Notifications |
Application notifications, including the status of activities that are occurring in the background (for example, music that is playing or files that are downloading), appear when users tap the exclamation mark icon in the top-left corner of the home screen. |
|
Scaling |
If you created your application for a smartphone, UI components will be scaled up for the BlackBerry PlayBook tablet. If you created your application for a tablet with a screen size that is larger than the screen size of the BlackBerry PlayBook tablet (7 inches), then UI components will be scaled down. |
If you want to optimize the layout of your UI, you can make adjustments to the UI components based on the following characteristics of the BlackBerry PlayBook tablet:
- Application icon size: 86 x 86 pixels
- Screen dimensions: 1024 x 600 pixels
- Pixels per inch (PPI): 169.3
- Image bit size: 32
- Image file type: .png
