UI leads to game crash

Questions & Answers
1

Hey guys,
I’ve updated my Unity to 5.1.2f1 and copied my project folder to a new PC. Now, after I build my Android game, it launches and crashes right after the splash screen. I took a look at the logcat output and it seems like it is able to finish the fist scene (OBB downloader) and then crashed due to an "Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 17343 (UnityMain)"error.

Edit: I was able to drag the issue down. It is caused by the UI. When I remove all UI elements from my scene, my game launches fine.

But I still don’t know how to fix this.

Full log can be found here.

Kind regards,
Tim

Same problem here.
I’ve been trying some stuff and finally found a workaround. In my project it’s caused by shaders not being preloaded, so…

Try this:

  1. Open the scene with UI texts.
  2. Go to menu option “Edit/Project settings/Graphics”.
  3. On “Shader preloading” hit “Clear” button. “Currently tracked” should switch to 0.
  4. Play the scene in the editor.
  5. Go back to graphics settings. “Currently tracked” should be now >0. Hit “Save to asset” button and save the file.
  6. Increase size by 1 to “Preloaded Shaders” and set your step2 file there.
  7. Save and run.

This should work for simple UI text, using colors and not materials. If you are setting shaders on runtime, I don’t know if it will help you. Also if there is text shown with a condition. Try playing the whole proyect and saving shaders then.

Hope it helps to someone else.
