Android权限BIND

本文介绍了Android权限BIND_NOTIFICATION_LISTENER_SERVICE无法正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用React Native Application.我正在Android中努力使用Notification Services& BIND_NOTIFICATION_LISTENER_SERVICE.我正在尝试使用NotificationListenerService阅读传入的通知.

I'm working in React Native Application. I'm trying hard in Android to make use of Notification Services & BIND_NOTIFICATION_LISTENER_SERVICE. I'm trying to read the incoming notifications using NotificationListenerService.

我正在使用 One Plus 5T(Android Oreo)进行调试.

我已经看到很多重复的问题，并且我已经尝试从这些问题中得到的以下解决方案.

I've seen lots of duplicate questions and I've tried the following solutions which I got from those questions.

1.重新启动手机(听起来很傻，无法正常工作)

1.Restarting the phone (Sounds silly and it doesn't work)

2.重新安装/重新构建应用程序

2.Re-install/Re-build the application

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.

1.Cannot see my application in 'Notification Access' settings.

2.onCreate/onNotificationPosted没有被调用

2.onCreate / onNotificationPosted is not getting called when I receive any Notification

3.使用以下代码检查我的应用程序是否具有通知"权限，并返回"false"(很明显，这是我的 问题)

3.Checked whether my application is having Notification permisson or not using the below code and it returned 'false' (Obviously, that's my problem)

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没有列出Dangerous permissions列表，所以我认为在清单中定义它(下面提供了源供您参考)就足够了，而不是询问运行时权限.

Since BIND_NOTIFICATION_LISTENER_SERVICE is not listed Dangerous permissions list, I thought defining it in Manifest (Source is given below for your reference) is enough instead of asking run time permission.

我已遵循此教程，也参考了其他教程.我找不到我做错了什么.一切看起来都很完美.经过一整天的努力，我以为我会寻求您的帮助.

I've followed this tutorial and referred other tutorials also. I can't find out where I'm doing wrong. Everything looks perfect. After scratching my mind for the whole day, I thought I'd ask your help.

在下面找到我的源代码.

我的来源

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 (甚至没有打印单个日志)

NotificationListener.java (Not even single log printed)

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); } } }

推荐答案

这很奇怪，但经过非常仔细的操作(无需跳过任何步骤)，第二天我就成功运行了

This is weird but I've got it successfully running the next day after doing the following things very carefully (Without skipping any steps)

卸载应用程序

Uninstall the Application

停止/关闭本机服务器

重命名NotificationListenerService类文件

重新连接USB电缆(如果不是模拟器)并更改连接类型 从Charge only到Media Transfer

Reconnect the USB cable (If not simulator) and change Connect type from Charge only to Media Transfer

构建您的android代码

Build your android code

执行react-native run-android

祈求上帝_/\ _(开个玩笑，但有帮助)

Pray God _/\_ (Just kidding, but it helps though)

祝你好运.
