BroadcastReciever中有阻塞调用导致死机

我是靠谱客的博主含蓄手套，这篇文章主要介绍BroadcastReciever中有阻塞调用导致死机，现在分享给大家，希望可以做个参考。

现象： CPU占用率高，系统卡死

log: Skipped 47 frames! The application may be doing too much work on its main thread.

原因：调用的底层接口中有阻塞：

sem_wait(&_uart_state.sem);

解决方法：创建一个线程来运行需要处理的代码：

if(action.equals(AudioManager.MASTER_MUTE_CHANGED_ACTION))
{
final boolean muted = intent.getBooleanExtra(AudioManager.EXTRA_MASTER_VOLUME_MUTED, false);
new Thread(new Runnable() {
public void run()
{
if(DEBUG) Log.v(TAG, "UartMcu mBroadcastReciever
MASTER_MUTE_CHANGED_ACTION muted = " + muted);
if(muted)
{
SetMuteHw(true);
}
else
{
SetMuteHw(false);
}
}
}).start();
}
