Using the APK to BAR Converter from Good E-Reader it should be possible to convert APK Android packages to BAR installation packages used by BlackBerry OS 10 operating system for Q5, Q10, Z3, Z10, Z30 and other BlackBerry smart phones.
In the past you could have also done this using BBHTool, however this seems to be outdated and pretty complicated method for converting .apk packages to .bar files.
Another thing is that not all mobile apps may be successfully converted from Android to Blackberry. There may be errors and the newly converted application can cause crashes or not work properly. In this case please check the app developer support for more information and possible solutions.
