libgdx使用了全屏模式之后，在某些机型会出现崩溃的情况，两年前就存在了，一直到现在为止，官方都没进行修复，其崩溃原因就是在源码AndroidGraphics.java中的onPause可以看到这样子的一段代码:

void pause () { synchronized (synch) { if (!running) return; running = false; pause = true; while (pause) { try { // TODO: fix deadlock race condition with quick resume/pause. // Temporary workaround: // Android ANR time is 5 seconds, so wait up to 4 seconds before assuming // deadlock and killing process. This can easily be triggered by opening the // Recent Apps list and then double-tapping the Recent Apps button with // ~500ms between taps. synch.wait(4000); if (pause) { // pause will never go false if onDrawFrame is never called by the GLThread // when entering this method, we MUST enforce continuous rendering Gdx.app.error(LOG_TAG, "waiting for pause synchronization took too long; assuming deadlock and killing"); android.os.Process.killProcess(android.os.Process.myPid()); } } catch (InterruptedException ignored) { Gdx.app.log(LOG_TAG, "waiting for pause synchronization failed!"); } } } }

崩溃的提示就是在这个方法中进行抛出的，解决方法就是,不让他抛出这个错误，就是在try里面把pause改为false，目前的解决方法是这样子，静候官方的修复了，自定义一个类，例如我用的是AndroidFragmentApplication，我自定义一个PatchedAndroidFragmentApplication，在onPause之后利用线程延迟100毫秒，执行一个onDrawFrame，使得pause为false即可：

open class PatchedAndroidFragmentApplication : AndroidFragmentApplication() { private val exec = Executors.newSingleThreadExecutor() private val forcePause = Runnable { try { Thread.sleep(100) } catch (e: InterruptedException) { } graphics.onDrawFrame(null) } override fun onPause() { if (activity!!.window.attributes.flags and WindowManager.LayoutParams.FLAG_FULLSCREEN == WindowManager.LayoutParams.FLAG_FULLSCREEN) { // 是全屏 exec.submit(forcePause) } super.onPause() }}

然后你的Fragment就继承这个自定义的类就行。
