Basically like what the title says, the app crashes whenever I run it when implementing buttons on stage. I also tried using logcat but even if i delete the line that it points out, there will be a new line that it will point out again, and again— until I even need to remove the Gdx.gl.glClearColor(1, 1, 1, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); in render method. Please help.
