Android Question abc_vector_test.xml / #7f020052 Crash

[wroyw]

Hi ,

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

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

How can I fix it ?

How can I fix it ?

Make sure not to have any BuildTools <25 installed. Only the newest one (25.0.2 or so). I mean in the SDK Manager

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.

now it works. Thank you
