The new devices don't support the old theme perfectly.
Why are you using the old theme?
Ok thanks. I set the targetSdkVersion to 15, but the problem is not resolved: the icon in the msgbox2 is not displayed.
Sorry, I forget to specify that the icon:
- is displayed BUT with fixed dimension, in Samsung GalaxyTab 2 (with Android 4.1);
- is NOT displayed, in Samsung GalaxyTab A (with Android 5);
What can I do in both cases? Thanks.
