Question

在我的Android应用程序中，我想拨打电话作为对特殊短信的回复。所以我创建了一个应用程序，它会监听即将发送的消息并因特定短信而拨打电话。该应用程序按预期在模拟器上运行，但是当我尝试在具有Android 4.0.3的选项卡上运行应用程序时，它会在启动调用后结束调用。这是我用过的代码。

public class MainActivity extends Activity {
public static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
String msgBody;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    IntentFilter filter = new IntentFilter(SMS_RECEIVED);
    registerReceiver(broadcastReceiver, filter);
}

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
         // TODO Auto-generated method stub

        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
            Bundle bundle = intent.getExtras();           
            SmsMessage[] msgs = null;
            String msg_from;
            if (bundle != null){

                try{
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    msgs = new SmsMessage[pdus.length];
                    for(int i=0; i<msgs.length; i++){
                        msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                        msg_from = msgs[i].getOriginatingAddress();
                        msgBody = msgs[i].getMessageBody();
                    }
                }catch(Exception e){

                }
            }
        }

        }
        Toast.makeText(getApplicationContext(), msgBody, Toast.LENGTH_LONG).show();

        if(msgBody.equals("CALL")){
            Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "XXXXXXXXXXX"));;
            myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
            context.startActivity(myIntent);
    }
};


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}    
}

我添加了以下权限：

 READ_SMS
 RECEIVE_SMS
 CALL_PHONE

这里有什么不对？请帮帮我。

先谢谢。

创建另一个活动，例如CallActivity，从您的接收者开始此活动，例如

 Intent i=new Intent();
 i.setClass(context,callActivity.class);
 i.putExtra("number","phone_number");
 i.setFlags(Intent.Flag_Activity_newTask);
 context.startActivity(i);

现在在CallActivity的onCreate（）方法中，只需启动呼叫电话意图：

  Intent myIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "XXXXXXXXXXX"));;
  startActivity(myIntent);

以编程方式在广播接收器中进行呼叫
