My Android RAZR phone shows all my controls, including buttons, just fine. When I load my app to the Google Nexus, the text on my buttons is not visible. Can anyone tell me why?
I guess that what you are seeing is the holo theme of Android 4. You can force your apps to use the old style (not recommended) by removing android:targetSdkVersion="14" from the manifest editor.
Another option is to set all the colors to the DEFAULT value in the designer.
