How do I use OTF files on Android?

To change font styles in GO Launcher, copy the TTF or OTF font files on your phone. Long press on the home screen and select GO Settings. Choose Font–>Select Font. Pick the font you want or tap Scan to add files stored on your device.

What format does Android use for fonts?

Fonts are compiled in R file and are automatically available in the system as a resource. You can then access these fonts with the help of the font resource type.

If by "custom font" you mean a font that you are supplying as an asset, the following code should work:

Typeface plain = Typeface.createFromAsset(assetManager, pathToFont);  Typeface bold = Typeface.create(plain, Typeface.DEFAULT_BOLD) Paint paint = new Paint(); paint.setTypeface(bold); canvas.drawText("Sample text in bold",0,0,paint);
