ANR意向广播

Question

我的应用程序中有一个BroadcastReceiver，它由ALARM_SERVICE每隔X秒调用一次。这个BroadcastReceiver调用另一个由AsyncTask运行的服务（试图避免阻塞主线程）但是我收到了一些来自我的用户的ANR以及google提供给我的日志如果我'我就无法读取它老实说。

有人可以帮我理解日志并解决问题吗？

这是Google向我提供的11页日志中的一页：

Answer 1

当发出警报时，请检查该服务是否已运行。如果它正在运行，则跳过或如果没有，则执行与您正在工作的相同的工作。 检查服务代码是否运行：

private boolean isMyServiceRunning（）{     ActivityManager manager =（ActivityManager）getSystemService（Context.ACTIVITY_SERVICE）;     for（RunningServiceInfo service：manager.getRunningServices（Integer.MAX_VALUE））{         if（MyService.class.getName（）。equals（service.service.getClassName（）））{             返回true;         }     }     返回false; }

可能是，你正在开始这么多服务。

Answer 2

我遇到了同样的问题，如果你使用两个线程会出现问题！：

首先从一个线程运行（例如：Asynctask）：

1. disableAutoCommit
2. 发生SQLiteException！
3. 还没有调用restoreAutocommit !!!

然后尝试使用来自其他线程的dao（例如：UI-Thread） - ＆gt;它将永远等待，因为第一个任务中缺少restoreAutocommit - ＆gt;这导致了ANR！

解决方案是：将finally添加到restoreAutocommit

示例：

    boolean prev = entityDao.disableAutoCommit();
    try
    {
        entityDao.disableAutoCommit();
        storeData(data);// if an Exception occurs -> finally is also called
    }
    finally
    {
        entityDao.restoreAutocommit(prev);
    }
