短信通知 - 不工作

sms notification- not working

我遇到了一些看似简单的事情。我想创建一个包含两个按钮的简单应用程序:一个用于启动服务,第二个用于停止服务。我已经创建了我的 NotifyService class:

public class NotifyService extends Service {
    public NotifyService() {
    }

    private static final String SMS_RECEIVED="android.provider.Telephony.SMS_RECEIVED";

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            displayNotification(intent);
        }
    };

    private void displayNotification(Intent intent)
    {
       if(intent.getAction().equals(SMS_RECEIVED)) {
           int NOTIFICATION=R.string.local_service_started;

            //notification creating
            Notification.Builder notificationBuilder = new Notification.Builder(this)
                    .setContentText("Otrzymano smsa!")
                    .setContentTitle("SMS!")
                    .setSmallIcon(android.R.drawable.btn_plus);
            Notification note = notificationBuilder.build();

            //getting system service
            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

            //displaying notification
            notificationManager.notify(NOTIFICATION, note);
       }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        unregisterReceiver(broadcastReceiver);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        registerReceiver(broadcastReceiver,new IntentFilter(SMS_RECEIVED));
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

这是我的 MainActivity:

的代码
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void startServiceBtn(View view)
    {
        Intent intent = new Intent(this,NotifyService.class);
        startService(intent);
    }

    public void stopServiceBtn(View view)
    {
        Intent intent = new Intent(this,NotifyService.class);
        stopService(intent);
    }

和清单:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.pablo.myapplication" >

    <uses-permission android:name="android.permission.RECEIVE_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=".MainActivity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:name=".NotifyService"
            android:enabled="true"
            android:exported="true" >
        </service>
    </application>

不幸的是,每次我通过 Android Device Monitor 模拟发送短信时,它都不起作用,它会向我显示默认系统通知(顺便说一下,即使在未经许可的情况下也会显示证明正确的行为?)

编辑:Android Device Monitor 中它仍然显示 Permission Denial: ... requires android.permission.RECEIVE_SMS due to sender.com android...。然而,我已经将它添加到 intent 过滤器中,然后我不知道为什么会这样。

这个问题的答案与我上次拥有权限的其他一些问题有关,并且与 Marshmallow 的新权限政治有关。更多信息 .

因此可以通过切换到较低的 sdk 版本或在运行时调用适当的方法(查看上面 link)来解决问题。
