Semi transparent textures look different on different android phones

Question

I'm using opengl, pretty new to it. Tried rendering a semi transparent cloud in my app recently but it looked different on my Galaxy S and my HTC desire HD :(.

Here is an image of the clouds on both phones clouds on Galaxy S and Desire HD.

Been reading around for ages, it seemed like Bitmap.config had smthng to do with the problem, so i added this line just before my bitmaps are loaded:

mBitmapOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;

There was no difference. Really appreciate any tips, thanks!

Edit:

I've added the following two lines in my onCreate method but the texture remains the same on both phones.

    getWindow().setFormat(PixelFormat.RGBA_8888);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DITHER);

Edit:

I've tried drawing the same image using the api demos static sprite activity to rule out mistakes in my code but got the same problem.

Edit:

Also tried drawing the same texture on a HTC Sensation and a LG Optimus 2x. Same problem on the HTC Sensation as on the Desire HD, no problems on the LG Optimus 2x.

Answer 1

Try enabling dithering by caling gl.glEnable(GL10.GL_DITHER) (or the equivalent of the gl version you are using if not GL10).

Edit: and if that don't work, also call getWindow().setFormat(PixelFormat.RGBA_8888); in your onCreate() method.

Answer 2

This question may be related to yours. Perhaps, you're running unofficial build on HTC Desire HD.

Also try following settings (call it in your Activity.onCreate(..) method):

getWindow().setFormat(PixelFormat.RGBA_8888);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DITHER);
