NotificationListenerServiceの実装
Android 4.3に追加されたNotificationListnerServiceを実装しようとしていますが、通知の詳細を取得できません。
私のコードは以下のとおりです
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setSmallIcon(R.drawable.ic_launcher);
mBuilder.setContentTitle("notification test");
mBuilder.setContentText("Notification text");
mBuilder.setAutoCancel(true);
Intent resultIntent = new Intent(this, ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1, mBuilder.build());
}
@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;
}
}
public class NotificationListenerTesting extends NotificationListenerService{
public static String TAG = "NotificationListenerTesting";
//private StatusBarNotification[] mStatusBarNotification;
@Override
public void onCreate(){
super.onCreate();
Log.d(TAG, "Inside on create");
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
TAG = "onNotificationPosted";
Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
"Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
TAG = "onNotificationRemoved";
Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
"Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
}
}
Androidマニフェストファイルは

package="com.example.notificationtest"

<intent-filter>
<action Android:name="Android.service.notification.NotificationListenerService"/>
</intent-filter>
</service>
</application>
</manifest>
しかし、通知をクリックした後、または通知ポストでNotificationListenerServiceが呼び出されない、これで何が問題なのか、または何かを逃したのですか？実装方法
NotificationListenerService内には、GUI対話を処理するブロードキャストを作成できるように、GUIスレッドと通信するルーパーが必要です。
希望 this の例が役立ちます。
通知を読むには、アプリへのアクセスを許可する必要があります：[設定]> [セキュリティ]> [通知アクセス]、アプリを確認します。
コードに関する少なくとも1つの問題は、onBind（）の実装です。
このメソッドをオーバーライドする必要はありません。ただし、必要な場合は、少なくともスーパークラスによって返されたIBinderを返します。
@Override
public IBinder onBind(Intent intent) {
return super.onBind(intent);
}
少し遅いかもしれません。しかし、数か月前、NotificationListenerServiceを機能させるのにも苦労しました。
それ以来、私はそれを実装する方法を学び、私と同じことを経験した他の人を助けるために実装チュートリアルを構築したいと感じました
誰かが興味がある場合は、ここでプロジェクトを確認してください： https://github.com/Chagall/notification-listener-service-example
それに苦しんでいる人を助けることを願っています。
私は質問に答えるには遅すぎることを知っていますが、設定>サウンドと通知->通知アクセスを見つけることができなかったので、このインテントを起動することでアプリへの通知へのアクセスを直接許可します：
startActivity（new Intent（Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS））;
私は同じ問題にぶつかり、そのための手がかりを見つけました。
NotificationListenerServiceは、bindService()を呼び出して起動しない限り実行されていない可能性があります。
「通知アクセス」を有効にすると自動的に開始される場合とそうでない場合があります。
作成する通知には「tickerText」がありません。通知にtickerTextがない場合、onNotificationPostedが呼び出されないことがわかりました。
コードにmBuilder.setTicker（ "your text here"）を追加します。
onNotificationPostedは、設定された残りのNotificationListenerServiceが適切であると仮定して呼び出されるようになりました。
私はGitHubと同じことをしていますが、それでも通知クラスには行きません。
