    copied!<p>I'm attempting to call a method which is outside the class I'm working in from an openGL thread but I'm getting a <code>Can't create handler inside thread that has not called Looper.prepare()</code> runtime exception. Does anyone know of a way around this without putting the method in the same class?</p> <p>Program breaks @ <code>Extract cam = new Extract();</code></p> <pre><code> public void onDrawFrame(GL10 gl) { onDrawFrameCounter++; gl.glEnable(GL10.GL_TEXTURE_2D); gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); bindCameraTexture(gl); System.out.println(Global.bearing); float bear = Global.bearing; gl.glLoadIdentity(); gl.glNormal3f(0,0,1); System.out.println("ARRAY!: " + GLCamTest.array.length); p = 0; gl.glRotatef(bear, 1, 0, 0); int q = 0; int e = 0; if(q &lt; Global.cubes){ Extract cam = new Extract(); Bitmap image = cam.extractimage(q); final int TILE_WIDTH = 512; final int TILE_HEIGHT = 512; final int TILE_SIZE = TILE_WIDTH * TILE_HEIGHT; int[] pixels = new int[TILE_WIDTH]; short[] rgb_565 = new short[TILE_SIZE]; // Convert 8888 to 565, and swap red and green channel position: int i = 0; for (int y = 0; y &lt; TILE_HEIGHT; y++) { image.getPixels(pixels, 0, TILE_WIDTH, 0, y, TILE_WIDTH, 1); for (int x = 0; x &lt; TILE_WIDTH; x++) { int argb = pixels[x]; int r = 0x1f &amp; (argb &gt;&gt; 19); // Take 5 bits from23..19 int g = 0x3f &amp; (argb &gt;&gt; 10); // Take 6 bits from15..10 int b = 0x1f &amp; (argb &gt;&gt; 3); // Take 5 bits from 7.. 3 int rgb = (r &lt;&lt; 11) | (g &lt;&lt; 5) | b; rgb_565[i] = (short) rgb; ++i; } } ShortBuffer textureBuffer = ShortBuffer.wrap (rgb_565, 0, TILE_SIZE); gl.glTexImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_RGB, 48, 48, 0, GL10.GL_RGB, GL10.GL_UNSIGNED_SHORT_5_6_5, textureBuffer); gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, e, 4); e = e + 4; q++; } } </code></pre>
