我正在 React Native 应用程序中工作。我正在努力在 Android 中使用Notification Services & BIND_NOTIFICATION_LISTENER_SERVICE。我正在尝试使用读取传入的通知NotificationListenerService.
我在用着一加 5T（安卓奥利奥）用于调试。
我见过很多重复的问题我试过了我从这些问题中得到了以下解决方案。
1.重启手机（听起来很傻而且不起作用）
2.重新安装/重新构建应用程序
- 重命名NotificationListenerService类文件并运行Etc..
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 不会被调用
3.使用下面的代码检查我的应用程序是否具有通知权限，它返回“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
Since BIND_NOTIFICATION_LISTENER_SERVICE未列出Dangerous permissions列表，我认为在清单中定义它（下面给出了源代码供您参考）就足够了，而不是询问运行时权限。
我已经关注了this http://www.androiddevelopersolutions.com/2015/05/android-read-status-bar-notification.html教程并还参考了其他教程。我找不到我哪里做错了。一切看起来都很完美。经过一整天的绞尽脑汁之后，我想我应该请求你的帮助。
在下面找到我的源代码。
感谢您的时间和耐心。 （：

private String TAG = this.getClass().getSimpleName();

public void onCreate() {
super.onCreate();
Log.d("KBT", "FROM LISTENER onCreate");

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");
}
}
通知监听器模块.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);
}
}
}
