Android Development : How to make Canvas.drawText() behave more consistently across different screen resolutions

If you want to keep the current default size but scale it according to the screen density, simply add this line of code.

int density = yourActivity.getApplicationContext().getResources().getDisplayMetrics().density; paint.setTextSize(density);

This will slightly scale it up or down, depending on whether the device is running at low or high density.
