I get this error and my app crashes when I run the app on a Android 4.4 ...
(on 6.0 it works fine)
I use the AppCompat library
B4X:
Shutting down VM
threadid=1: thread exiting with uncaught exception (group=0xa4c8eb20)
java.lang.RuntimeException: Unable to start activity ComponentInfo{b4a.example/b4a.example.prefs2}: android.content.res.Resources$NotFoundException: File res/drawable/abc_vector_test.xml from drawable resource ID #0x7f020052
okay , da waren ja ziemlich viele <25 installiert ... mind. 10 Stück
Nun kommt diese Meldung :
java.lang.RuntimeException: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
