Libgdx解决部分Android机型锁屏崩溃的方法

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!");        }      }    }  }

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()  }}
