The exception is thrown the 1st time around the loop. And Unlock is never called, since there was never a successful Lock in the first place... :(
Right now, my code looks like this one: http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/graphics/GLSurfaceView.html However, in the run() method, instead of having: if ((w > 0) && (h > 0)) { /* draw a frame here */ mRenderer.drawFrame(gl); /* * Once we're done with GL, we need to call swapBuffers() * to instruct the system to display the rendered frame */ mEglHelper.swap(); } I modified it a little: if ((w > 0) && (h > 0)) { mRenderer.drawFrame(gl); if (mRun){ Canvas c = null; try { mHolder = getHolder(); //make sure holder is updated c = mHolder.lockCanvas(); synchronized (mHolder) { if (mMode == STATE_RUNNING && c != null){ doDraw(c); } } } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { mHolder.unlockCanvasAndPost(c); } } } mEglHelper.swap(); } On Apr 8, 4:04 am, "[email protected]" <[email protected]> wrote: > Sorry, I misread your code before.
