关于broadcastreceiver：在android中检查SIM卡状态时”两次调用registerBroadcastReceiver”

"Called registerBroadcastReceiver twice" when checking Sim card state in android

我有一个广播接收器，它使用 TelephonyManager 检查 SIM 卡状态何时发生变化。

public void onReceive(final Context context, Intent intent) {

TelephonyManager telephoneMgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
int simState = telephoneMgr.getSimState();
String sim = Integer.toString(simState);

switch (simState) {
case TelephonyManager.SIM_STATE_ABSENT:
System.out.println("*******************************************Sim State absent******************************");
Log.i("SimStateListener","Sim State absent");
break;
case TelephonyManager.SIM_STATE_NETWORK_LOCKED:
System.out.println("*******************************************SIM_STATE_NETWORK_LOCKED******************************"+simState);
Log.i("SimStateListener","Sim State network locked");
break;
case TelephonyManager.SIM_STATE_PIN_REQUIRED:
System.out.println("*******************************************SIM_STATE_PIN_REQUIRED******************************"+simState);
Log.i("SimStateListener","Sim State pin required");
break;
case TelephonyManager.SIM_STATE_PUK_REQUIRED:
System.out.println("*******************************************SIM_STATE_PUK_REQUIRED******************************"+simState);
Log.i("SimStateListener","Sim State puk required");
break;
case TelephonyManager.SIM_STATE_UNKNOWN:
System.out.println("*******************************************SIM_STATE_UNKNOWN******************************"+simState);
Log.i("SimStateListener","Sim State unknown");
break;
case TelephonyManager.SIM_STATE_READY:
Log.i("SimStateListener","Sim State ready");
try{
String imsi = telephoneMgr.getSubscriberId();
Log.i("SubscriberId","SubscriberId" + imsi);
if(imsi.equals("MY IMSI")){
Log.i("SimStateListener","Sim card is the same");

}
else{

Log.i("SimStateListener","Sim card is changed, Call the police");

// if phone is connected to the internet
if(isNetworkAvailable(context)){
Log.i("internet","phone is connected");
Intent simChangedService = new Intent(context, SimChangedService.class);
SimChangedService.startYourService(context, simChangedService);
} // if phone is not connected to the internet, turns on 3G
else{
Log.i("internet","phone is not connected");
setMobileDataEnabled(context, true);
Log.i("internet","Mobile data enabled");
Intent simChangedService = new Intent(context, SimChangedService.class);
SimChangedService.startYourService(context, simChangedService);
}

}

} catch (Exception e) {
Log.i("SubscriberId","SubscriberId is null");
Log.i("SubscriberId", e.getMessage());
}
break;
}

这是 Intent 服务中的 onHandleIntent ：

public class SimChangedService extends IntentService {
public static void startYourService(Context ctxt, Intent i) {
getLock(ctxt.getApplicationContext()).acquire();
ctxt.startService(i);
}
protected void onHandleIntent(Intent arg0) {
// TODO Auto-generated method stub

Toast.makeText(this,"service starting", Toast.LENGTH_SHORT).show();

try{
getPhoneLocation();

ArrayList<String> locationList = new ArrayList<String>();
locationList.add(longt);
locationList.add(lat);

//Executes an AsyncTask to send an email
SendEmailTask sendTask = new SendEmailTask(this);
sendTask.execute(locationList);
//Toast.makeText(this,"i have executed sendTask", Toast.LENGTH_LONG).show();
Log.i("AsyncTask","i have executed sendTask");
scheduleAlarm();
}finally{

PowerManager.WakeLock lock = getLock(this.getApplicationContext());
if (lock.isHeld()) {
lock.release();
Log.i("wakelock","lock is released");
}
}
}
}

我不调用 registerReceiver()，我只在清单中有这个：

一切正常，但我在 LogCat 中遇到错误："两次调用 registerBroadcastReceiver"。
有谁知道解决方案？
谢谢。
