I want draw Text on OpenGL.

I try use Bitmap,Canvas,Paint.

public void GLText(GL10 gl) {
    Bitmap bitmap = Bitmap.createBitmap(256, 256, Bitmap.Config.ARGB_4444);
    Canvas canvas = new Canvas(bitmap);
    bitmap.eraseColor(0);

    Paint paint = new Paint();
    paint.setTextSize(18);
    paint.setAntiAlias(true);
    paint.setARGB(0xff, 255, 0, 255);
    paint.setTextAlign(Paint.Align.LEFT);
    paint.setTextScaleX(0.5f);

    canvas.drawColor(Color.BLUE);
    canvas.drawText("testGLText", 10.f, 15.f, paint);

    GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);
}
