Try to draw text on bitmap following this

 public Bitmap drawTextToBitmap(Context gContext, 
  int gResId, 
  String gText) {
  Resources resources = gContext.getResources();
  float scale = resources.getDisplayMetrics().density;
  Bitmap bitmap = 
      BitmapFactory.decodeResource(resources, gResId);

  android.graphics.Bitmap.Config bitmapConfig =
      bitmap.getConfig();
  // set default bitmap config if none
  if(bitmapConfig == null) {
    bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
  }
  // resource bitmaps are imutable, 
  // so we need to convert it to mutable one
  bitmap = bitmap.copy(bitmapConfig, true);

  Canvas canvas = new Canvas(bitmap);
  // new antialised Paint
  Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
  // text color - #3D3D3D
  paint.setColor(Color.rgb(61, 61, 61));
  // text size in pixels
  paint.setTextSize((int) (14 * scale));
  // text shadow
  paint.setShadowLayer(1f, 0f, 1f, Color.WHITE);

  // draw text to the Canvas center
  Rect bounds = new Rect();
  paint.getTextBounds(gText, 0, gText.length(), bounds);
  int x = (bitmap.getWidth() - bounds.width())/2;
  int y = (bitmap.getHeight() + bounds.height())/2;

  canvas.drawText(gText, x, y, paint);

  return bitmap;
}
