Question

我按照教程接收短信并在我的应用上显示。然而，当我尝试使用Android设备监视器（以及使用android终端的telnet）发送短信时，模拟器本身会收到短信，但应用程序什么都不做。

代码如下......

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.TextView;
import android.widget.Toast;

public class Sms extends Activity {

TextView t1;
BroadcastReceiver receiver = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sms);
    t1 = (TextView) findViewById(R.id.textView);

    IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
    receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arr0, Intent arr1) {
            processReceive(arr0, arr1);
        }
    };
    registerReceiver(receiver, filter);
}

protected void onDestroy() {
    super.onDestroy();
    unregisterReceiver(receiver);
}

public void processReceive(Context context, Intent intent) {
    Toast.makeText(context, "Incoming...", Toast.LENGTH_LONG).show();

    Bundle bundle = intent.getExtras();
    Object[] objArr = (Object[]) bundle.get("pdus");
    String sms = "";

    for (int i = 0; i < objArr.length; i++) {
        SmsMessage smsMsg = SmsMessage.createFromPdu((byte[]) objArr[i]);

        String smsBody = smsMsg.getMessageBody();
        sms += smsBody;
    }
    t1.setText(sms);
}
}

Manifest.xml如下......

<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".Sms">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

有什么建议吗？模拟器接收短信但不接收应用程序。我也尝试在intent-filter标签中使用android：priority属性，但没有任何效果。吐司应该显示＆＃34; Incoming ...＆＃34;当调用onReceive方法时也没有调用（表明应用程序没有收到短信）。权限对我来说也很好看。请帮忙......
