Android developers transitioning their apps to BlackBerry 10 will have the ability to eliminate the back-bar entirely (on a per-app basis) in OS 10.2.1.
It’s quite simple actually. All that is required is the addition of a small configuration file during the repackaging process.
    android.cfg <?xml version=â€Â1.0†encoding=â€Âutf-8â€Â?> <android>  <config>    <overridenavbar />  </config> </android>
When and where you should add this file is important, so let’s walk through it together.
- Convert your APK using blackberry-apkpackager.
- Open the BAR file for editing using the utility of your choice.
- Place the android.cfg file inside YourApp.bar/android.
- Save your changes back.
- Sign the BAR using blackberry-signer.
- Deploy
Remember that the additional configuration file will only take effect on operating systems 10.2.1 and greater.[signoff predefined=”Enjoy this?” icon=”icon-users”][/signoff]Via
