我正在使用React Native Application。我正在Android上努力使用Notification Services和BIND_NOTIFICATION_LISTENER_SERVICE。我正在尝试使用NotificationListenerService阅读传入的通知。
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。
1。重新启动手机（听起来很傻，无法正常工作）
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。
当我收到任何通知时，2.onCreate / onNotificationPosted没有被调用
3。使用以下代码检查我的应用程序是否具有Notification permisson并返回“ false”（很明显，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不在Dangerous permissions列表中，因此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。
我已经遵循this教程，并且还参考了其他教程。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，我想找你帮忙。
在下面找到我的源代码。

NotificationListener.java （甚至没有打印单个日志）
public class NotificationListener extends NotificationListenerService {

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

String pack = sbn.getPackageName();
String ticker ="";
if(sbn.getNotification().tickerText !=null) {

答案 0 :(得分：0)
这很奇怪，但经过非常仔细的操作（无需跳过任何步骤），第二天我就成功地运行了它
卸载应用程序
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
构建您的android代码
执行react-native run-android
祈求上帝_ / \ _（开个玩笑，但有帮助）
好运。
