Adjust your Android application
Handling update notifications
The BlackBerry World storefront prompts the application user if any updates for the application are available in BlackBerry World. You must remove any intents, update checks, or prompts for Android Market that may exist in your application code, as they may lead to a negative user experience.
Resizing your application icon
Application icons on the BlackBerry PlayBook tablet and BlackBerry 10 devices are larger than the application icons on Android devices. On the BlackBerry PlayBook tablet, icons should be 86 x 86 pixels. On a BlackBerry 10 device, icons should be 114 x 114 pixels.
For best results, you should resize your application icon appropriately before you repackage your app. The BlackBerry Runtime for Android apps allows you to support more than one BlackBerry device in a single release build (BAR file) so you can adjust the icon size for each one appropriately.
