Simple Android signature check. Please note: This was created in 2013, not actively maintained and may not be compatible with the latest Android versions. It's not particularly difficult for an attacker to decompile an .apk, find this tamper check, replace the APP_SIGNATURE with theirs and rebuild (or use method hooking to return true from `valiโ€ฆ

If you need to set one font for all TextViews in android application you can use this solution. It will override ALL TextView's typefaces, includes action bar and other standard components, but EditText's password font won't be overriden.
public class MyApp extends Application {
@Override
public void onCreate() {
TypefaceUtil.overrideFont(getApplicationContext(), "SERIF", "fonts/Roboto-Regular.ttf"); // font from assets: "assets/fonts/Roboto-Regular.ttf
}
}
