Android TextToSpeech使用WakefulBroadcastReceiver

如何使用WakefulBroadcastReceiver使用文本到语音功能onPause方法我为此制作了以下类： 我正在使用Receiver接收GCM推送通知，此代码在Receive方法上运行良好，但当应用程序处于暂停状态且NotificationManager中的通知在此时应用程序崩溃时，请帮助我解决此问题 GCMBroadcastereceiver

以下是我所面临的例外

您应该在onReceive中启动服务，并将消息传递给speak

@Override
public void onReceive(Context context, Intent intent)
{
     intent.setAction("speak");
     intent.putExtra("welcome_message", "asdas");
     intent.putExtra("body", "asdas");
     startService(intent.setComponent(new ComponentName(context.getPackageName(),
                MyService.class.getName())));
      // Where MyService is the service that you implements TTS
}

然后在服务班

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    if (intent != null)
    {
        String action = intent.getAction();
        if ("speak".equals(action))
        {
             // check if TTS is initialize if so speak the extra
             // otherwise save the extra to class members and when onInit is called
             // check if these class members are null then speak 
        }
    }
}

@Override
public void onReceive(Context context, Intent intent)
{
     intent.setAction("speak");
     intent.putExtra("welcome_message", "asdas");
     intent.putExtra("body", "asdas");
     startService(intent.setComponent(new ComponentName(context.getPackageName(),
                MyService.class.getName())));
      // Where MyService is the service that you implements TTS
}

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    if (intent != null)
    {
        String action = intent.getAction();
        if ("speak".equals(action))
        {
             // check if TTS is initialize if so speak the extra
             // otherwise save the extra to class members and when onInit is called
             // check if these class members are null then speak 
        }
    }
}
