Using use_local_qt_libs

[BogDan]

Hi,

Try to use QtCreator. This are the steps I'm using to develop qt on android:
1. build qt for Android.
2. Add it to QtCreator Qt Versions and Kits.
3. Import qt build to QtCreator.
4. create a new application based on previous kit.
5. check "Deploy local Qt libs" to push these libs to the device.
6. start application and debug.
7. most of the time I need to restart the debugging or to change only the application so I go to step 6
8. (only if) I do some changes to qt.
9. build qt (build all projects)
10. go to step 5 (not 6 !).
