android 手机应用设备管理激活状态，获取激活状态，监听激活状态

       

注册一个Receiver

<receiver
   android:name="LockReceiver"
   android:description="@string/app_name"
   android:label="@string/app_name"
   android:permission="android.permission.BIND_DEVICE_ADMIN" >
   <meta-data
       android:name="android.app.device_admin"
       android:resource="@xml/lock_screen" />

   <intent-filter>
       <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
   intent-filter>
receiver>

配置权限文件lock_screen.xml，将文件放置在/res/xml/下

xml version="1.0" encoding="UTF-8"?>
<device-admin xmlns:android="http://schemas.android.com/apk/res/android" >

    <uses-policies>


        <force-lock />


        <wipe-data />


        <reset-password />


        <limit-password />


        <watch-login />

    uses-policies>

device-admin>

实现Receiver

package com.huron.xx;

import android.app.admin.DeviceAdminReceiver;
import android.content.Context;
import android.content.Intent;

public class LockReceiver extends DeviceAdminReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
        System.out.println("onreceiver");
    }

    @Override
    public void onEnabled(Context context, Intent intent) {
        System.out.println("激活使用");
        super.onEnabled(context, intent);
    }

    @Override
    public void onDisabled(Context context, Intent intent) {
        System.out.println("取消激活");
        super.onDisabled(context, intent);
    }

}

获取激活状态

public class AdminActiveWrapper {
   DevicePolicyManager dpm;
   ComponentName adminComponent;
   private Activity context = null;

   public void init(Activity ctx) {
      context = ctx;
      dpm = (DevicePolicyManager) context
            .getSystemService(Context.DEVICE_POLICY_SERVICE);
      adminComponent = new ComponentName(context, LockReceiver.class);
   }

   public boolean isEnabled(){
      return dpm.isAdminActive(adminComponent);
   }

   public void checkAndEnableAdmin() {
      if (!dpm.isAdminActive(adminComponent)) {
         Intent intent = new Intent(
               DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
//       intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,
               adminComponent);
         intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
               context.getString(R.string.device_admin_hint));
         context.startActivityForResult(intent, 0);
      }
   }

}

public class S1Activity extends Activity {

    @Override
   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      // TODO Auto-generated method stub
      super.onActivityResult(requestCode, resultCode, data);
      finish();
   }

   DevicePolicyManager dpm;
    ComponentName adminComponent;
    
   void checkAndEnableAdmin() {
        if (!dpm.isAdminActive(adminComponent)) {
            Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
            intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, adminComponent);
            intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, this.getString(R.string.device_admin_hint));
            startActivityForResult(intent, 0);
        }
        else {
           finish();
        }
    }
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_s1);
      dpm = (DevicePolicyManager) getSystemService(DEVICE_POLICY_SERVICE);
      adminComponent = new ComponentName(this, LockReceiver.class);        
      PermissionManager.upgradeRootPermission(getPackageCodePath());
      checkAndEnableAdmin();
   }
}
