android|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 android|软件

注册一个Receiver

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

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

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(); } }
