java - 执行 SystemJobService 期间的 ANR

Question

我在我的应用程序中收到以下 ANR（运行大约 30 小时或更长时间后），有关该应用程序的更多详细信息：

1. 重复播放视频
2. 始终保持屏幕开启
3. 在后台有文件下载服务（低于其使用率 0.1%）
4. 后台服务每 5 分钟 ping 一次我们的服务器
5. 一些工作人员做一些事情

这是原因：

public synchronized void release() {
    if (released || !internalPlaybackThread.isAlive()) {
      return;
    }
    handler.sendEmptyMessage(MSG_RELEASE);
    boolean wasInterrupted = false;
    while (!released) {
      try {
        wait(); // here....
      } catch (InterruptedException e) {
        wasInterrupted = true;
      }
    }
    if (wasInterrupted) {
      // Restore the interrupted status.
      Thread.currentThread().interrupt();
    }
  }

• 如何处理？
• 我的应用程序使用率是 24%，是好还是这些数字无法衡量我的应用程序的 cpu 使用率

建议
