我正在开发React Native应用。我在Android上努力使用Notification Services和BIND_NOTIFICATION_LISTENER_SERVICE。我正在尝试使用NotificationListenerService读取来电通知。
我使用One Plus 5T (Android Oreo)进行调试。
我已经尝试了很多重复的问题解决方案，包括：
1.重新启动手机（听起来有点傻，但并没有起作用）
2.重新安装/重建应用程序
- 重命名NotificationListenerService类文件并运行等。
我一直面临的问题：
1.在“通知访问”设置中看不到我的应用程序。
2.当我收到任何通知时，onCreate/onNotificationPosted都没有被调用。
3.使用下面的代码检查我的应用程序是否具有通知许可，并返回“false”（显然，这是我的问题）
ComponentName cn = new ComponentName(getReactApplicationContext(), NotificationListener.class);
String flat = Settings.Secure.getString(getReactApplicationContext()
.getContentResolver(), "enabled_notification_listeners");
final boolean hasPermission = flat != null && flat.contains(cn.flattenToString());
// hasPermission - false
由于BIND_NOTIFICATION_LISTENER_SERVICE未列在Dangerous permissions清单中，我认为在Manifest中定义它（下面为您提供了源代码）就足够了，而不需要请求运行时权限。
我按照此教程以及其他教程进行操作，但是找不出我的错误所在。一切看起来完美无缺。在整整一天的思考后，我认为我需要寻求您的帮助。
请在下面查看我的源代码。
非常感谢您的时间和耐心。（:
我的源代码
AndroidManifest.xml
<service
android:name=".NotificationListener"
android:label="@string/app_name"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
NotificationListener.java（没有任何日志输出）
public class NotificationListener extends NotificationListenerService {
Context context;
private String TAG = this.getClass().getSimpleName();
@Override
public void onCreate() {
super.onCreate();
Log.d("KBT", "FROM LISTENER onCreate");
context = getApplicationContext();
}
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
Log.d("KBT", "FROM LISTENER onNotificationPosted");
String pack = sbn.getPackageName();
String ticker ="";
if(sbn.getNotification().tickerText !=null) {
ticker = sbn.getNotification().tickerText.toString();
}
Bundle extras = sbn.getNotification().extras;
String title = extras.getString("android.title");
String text = extras.getCharSequence("android.text").toString();
Intent msgrcv = new Intent("NOTIFICATION_POSTED_KBT");
msgrcv.putExtras(extras);
LocalBroadcastManager.getInstance(context).sendBroadcast(msgrcv);
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
Log.i(TAG, "********** onNOtificationRemoved");
}
}
NotificationListenerModule.java
public class NotificationListenerModule extends ReactContextBaseJavaModule {
Context mainContext;
public NotificationListenerModule(ReactApplicationContext reactContext) {
super(reactContext);
mainContext = getReactApplicationContext();
}
@Override
public String getName() {
return "BatteryStatus";
}
@ReactMethod
public void registerNotificationEvent(Callback successCallback) {
// This log is printed successfully hence this function is getting called.
Log.d("KBT","registerNotificationEvent called");
// Registering Receiver
LocalBroadcastManager.getInstance(mainContext).registerReceiver(myReceiver, new IntentFilter("NOTIFICATION_POSTED_KBT"));
// Check Notification Permission in our app
ComponentName cn = new ComponentName(getReactApplicationContext(), NotificationListener.class);
String flat = Settings.Secure.getString(getReactApplicationContext().getContentResolver(), "enabled_notification_listeners");
final boolean enabled = flat != null && flat.contains(cn.flattenToString());
] }
private class NLServiceReceiver extends BroadcastReceiver {
@Override public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
JSONObject json = new JSONObject();
Set<String> keys = bundle.keySet();
for (String key : keys) {
try {
// json.put(key, bundle.get(key)); see edit below
json.put(key, JSONObject.wrap(bundle.get(key)));
} catch(JSONException e) {
//Handle exception here
}
}
// Emitting the event to React Native
getReactApplicationContext()
.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
.emit("onNotificationPosted", json);
}
}
