Alpha Background on android

[fdecampredon]

Is there a way to have transparent surface background on android ?

renderer.setClearColor (0x000000, 0); works just fine on iOS, anybody got an idea why it won't work on Android?

I'm also trying to get this done. Is there any way to do this? If I simply render an empty webglView with

      gl.enable( gl.BLEND );
      gl.blendEquationSeparate( gl.FUNC_ADD, gl.FUNC_ADD );
      gl.blendFuncSeparate( gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA, gl.ONE, gl.ONE_MINUS_SRC_ALPHA );

      gl.colorMask(true, true, true, true);
      gl.clearColor(0.0,0.0, 0.0, 0.0);
      gl.clear(gl.COLOR_BUFFER_BIT);
      // ignore texture drawing for this test
      // gl.drawArrays(gl.TRIANGLES, 0, 3);
      gl.flush();
      rngl.endFrame();

all I get is a black background.. Any suggestions?

Yeah, I‘m about to look for somebody on Upwork or something, this is a dealbreaker for an app I was working on..

is this problem fixed in current expo GLView implementation? If yes, maybe worth trying to port latest stuff. actually maybe you guys want to take a look at #63 . i have very few time to work on this & maintain this right now, but hopefully I'll have more during this summer

Check my fork armenbadalyan@830b213
It makes GLSurfaceView transparent at the cost of placing it above everything else on that view.
