onServiceConnected在启用我的AccessibilityService之后未调用

打开我的应用程序后，它跳转到可访问性设置。但是在打开我的AccessibilityService（称为VoiceService）之后，不会调用onServiceConnected。onServiceConnected在启用我的AccessibilityService之后未调用

请问我该怎么办？似乎VoiceService无法启动，尽管我在XML中启用它。或者我需要以不同的方式将MainActivity与VoiceService绑定？

的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.wang.hearexpr"> 
<uses-permission 
    android:enabled="true" 
    android:name="android.permission.BIND_ACCESSIBILITY_SERVICE"/> 
<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme"> 
    <activity android:name=".MainActivity"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <service android:name=".VoiceService" 
     android:enabled="true" 
     android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" 
     android:label="@string/service_name"> 
     <meta-data 
      android:name="android.accessibilityservice" 
      android:resource="@xml/voice_config"/> 
     <intent-filter> 
      <action android:name="android.accessibilityservice.AccessibilityService"/> 
     </intent-filter> 

    </service> 

</application> 
</manifest>

voice_config.xml

<?xml version="1.0" encoding="utf-8"?> 
<accessibility-service 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:description="@string/service_description"

    android:canRetrieveWindowContent="true" 
    android:canRequestTouchExplorationMode="true" 
    android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity"/>

VoiceService.java

package com.example.wang.hearexpr; 
import android.accessibilityservice.AccessibilityService; 
import android.accessibilityservice.AccessibilityServiceInfo; 
import android.content.Intent; 
import android.os.Handler; 
import android.util.Log; 
import android.view.accessibility.AccessibilityEvent; 

public class VoiceService extends AccessibilityService { 
    private static final String TAG = "hear the voice"; 
    @Override 
    public void onServiceConnected(){ 
     super.onServiceConnected(); 
     Log.d(TAG, "Service Connected"); 
    } 

    @Override 
    public void onAccessibilityEvent(AccessibilityEvent event) { 
     Log.d(TAG,"onAccessibilityEvent: "+ event.toString()); 
    } 
    @Override 
    public void onInterrupt() { 
     Log.d(TAG, "Interrupted"); 
    } 
    @Override 
    public void onDestroy(){ 
     Log.d(TAG, "Destroyed"); 
    } 
}

MainActivity.java

package com.example.wang.hearexpr; 

import android.content.Intent; 
import android.provider.Settings; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class MainActivity extends AppCompatActivity { 
    private static final Intent sSettingsIntent = 
     new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS); 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     startActivityForResult(sSettingsIntent,0); 
    } 
}

这就是答案：在voice_config.xml

android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity"应修改为自己的活动名称。
