Question

应用程序因为第一次出现一些错误而崩溃后，NLService又被创建并绑定了，但是在第二次或第三次......之后，NLService还没有被创建和绑定，甚至是

中的复选框

Settings > Security > Notification access

已经过检查，我该怎么办？

NLService：

import android.content.Intent;
import android.os.IBinder;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;

public class NLService extends NotificationListenerService {
  private String TAG = this.getClass().getSimpleName();
  @Override
  public void onCreate() {
    super.onCreate();
    Log.d(TAG, "==onCreate==");
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
    Log.d(TAG, "==onDestroy==");
  }

  @Override
  public void onNotificationPosted(StatusBarNotification sbn) {
    Log.i(TAG, "**********  onNotificationPosted");
    Log.i(TAG, "ID :"
        + sbn.getId()
        + "\t"
        + sbn.getNotification().tickerText
        + "\t"
        + sbn.getPackageName());
  }

  @Override
  public void onNotificationRemoved(StatusBarNotification sbn) {
    Log.i(TAG, "********** onNOtificationRemoved");
    Log.i(TAG, "ID :"
        + sbn.getId()
        + "\t"
        + sbn.getNotification().tickerText
        + "\t"
        + sbn.getPackageName());
  }

  @Override public int onStartCommand(Intent intent, int flags, int startId){
    Log.d(TAG, "==onStartCommand==");
    return super.onStartCommand(intent, flags, startId);
  }

  @Override public IBinder onBind(Intent intent) {
    Log.d(TAG, "==onBind==");
    return super.onBind(intent);
  }

  @Override public void onRebind(Intent intent) {
    super.onRebind(intent);
    Log.d(TAG, "==onRebind==");
  }

  @Override public boolean onUnbind(Intent intent) {
    Log.d(TAG, "==onUnbind==");
    return super.onUnbind(intent);
  }
}

并在manifest.xml中注册

<service android:name="com.kpbird.nlsexample.NLService"
         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>

还有问题吗？

我处于相同的情况，这个NLService似乎不会合作......

作为“假”解决方法我注意到如果您在调试会话期间检查并取消选中Settings > Security > Notification access并在onCreate（）中放置断点，则可以在服务时拦截开始，但不是很清楚为什么有时会停止......

另一种可能性是重启设备......

尝试也许你会找到一种方法来解决，我还在努力......

的更新

也许服务中的某些内容发生了变化。这是我在多个设备上运行的测试（我已经试了几天）。

安装应用程序后，您可以在设置中启用通知访问，而不是尝试代码。

build.gradle 文件

apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.2" defaultConfig { applicationId "your_application_id" minSdkVersion 18 targetSdkVersion 23 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.android.support:design:23.1.1' }

AndroidManifest.xml file
这里我们使用NotificationListener声明并添加服务（我们创建的类的名称）

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="insert_your_package"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".AMain" android:label="@string/app_name" android:theme="@style/AppTheme.NoActionBar"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <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> </application> </manifest>

AMain.java 文件

package insert_your_package; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.content.IntentFilter; import android.os.Bundle; import android.support.design.widget.FloatingActionButton; import android.support.design.widget.Snackbar; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import android.view.View; import android.view.Menu; import android.view.MenuItem; import android.widget.TextView; public class AMain extends AppCompatActivity { protected TextView textView; protected NotificationReceiver notificationReceiver; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.a_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) .setAction("Action", null).show(); } }); textView = (TextView) findViewById(R.id.textview); notificationReceiver = new NotificationReceiver(); IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("com.dev.name.test"); registerReceiver(notificationReceiver, intentFilter); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } class NotificationReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String temp = intent.getStringExtra("notification_event") + "\n" + textView.getText(); textView.setText(temp); } } }

NotificationListener.java 文件

package insert_your_package; import android.content.Intent; import android.service.notification.NotificationListenerService; import android.service.notification.StatusBarNotification; import android.util.Log; public class NotificationListener extends NotificationListenerService { private String TAG = this.getClass().getSimpleName(); @Override public void onNotificationPosted(StatusBarNotification sbn) { Log.i(TAG, "********** onNotificationPosted"); Log.i(TAG, "ID :" + sbn.getId() + "\t" + sbn.getNotification().tickerText + "\t" + sbn.getPackageName()); Intent i = new Intent("com.dev.name.test"); i.putExtra("notification_event", sbn.getPackageName() + " posted"); sendBroadcast(i); } @Override public void onNotificationRemoved(StatusBarNotification sbn) { Log.i(TAG, "********** onNotificationPosted"); Log.i(TAG, "ID :" + sbn.getId() + "\t" + sbn.getNotification().tickerText + "\t" + sbn.getPackageName()); Intent i = new Intent("com.dev.name.test"); i.putExtra("notification_event", sbn.getPackageName() + " removed"); sendBroadcast(i); } @Override public void onDestroy() { super.onDestroy(); } }

正如您所看到的那样，文字会添加发生的每个通知发布或已移除。现在服务正常运行，我们可以做出我们想要的东西。

尝试并判断它是否有效。

Android：NotificationListenerService尚未重新创建
