添加当前程序到设备管理列表里

1、权限配置

详细请参考Device Administration以及DeviceAdminReceiver的相关文档

根据sdk文档，说明，先创建Androidmanifest.xml，它必须包含如下信息

子类(继承自DeviceAdminReceiver)需要包含以下两点：

必须拥有BIND_DEVICE_ADMIN

能处理ACTION_DEVICE_ADMIN_ENABLED的intent请求，并在xml中声明为一个intent

在metadata中进行安全声明

下面是一个manifest例子

<receiver
android:name=".myDeviceAdminReceiver"
android:permission="android.permission.BIND_DEVICE_ADMIN" >
<meta-data
android:name="android.app.device_admin"
android:resource="@xml/device_admin_sample" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>

a) meta-data项是必须的，还有权限以及intent-filter
b) android:resource对应的xml需要自己创建，并放在xml目录下，xml目录没有自己创建，其内容如下：

<?xml version="1.0" encoding="utf-8"?>
<device-admin
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-policies>
<force-lock />
</uses-policies>
</device-admin>

2、代码部分，创建继承子类MyDeviceAdminReceiver

public class myDeviceAdminReceiver extends DeviceAdminReceiver{

private static String TAG = "TestHello";
@Override
public void onEnabled(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onEnabled(context, intent);
Toast.makeText(context, context.getResources().getString(R.string.device_admin_jihuo_success_tips), Toast.LENGTH_LONG).show();;
Log.i(TAG, "DeviceAdminReceiver::onEnabled");
}

@Override
public CharSequence onDisableRequested(Context context, Intent intent) {
// TODO Auto-generated method stub
//这里如果返回的字符串不为空，那么当用户去设置里取消时，则会提示带此文字的确定框
String strResult = "请不要取消，谢谢！！！";
Log.i(TAG, "DeviceAdminReceiver::onDisableRequested");
//return super.onDisableRequested(context, intent);
return strResult;
}

@Override
public void onDisabled(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onDisabled(context, intent);
Log.i(TAG, "DeviceAdminReceiver::onDisable");
Toast.makeText(context, context.getResources().getString(R.string.device_admin_cancel_jihuo_tips), Toast.LENGTH_LONG).show();;
}

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onReceive(context, intent);
Log.i(TAG, "DeviceAdminReceiver::onReceive");
}

}

3、编写添加进入设备的代码

public void OpenDevicePolicyManager(Context context)
{
DevicePolicyManager dManager = (DevicePolicyManager) context.getSystemService("device_policy");//获取manager对象
ComponentName localComponentName = new ComponentName(this, myDeviceAdminReceiver.class);
if (dManager != null &&
localComponentName != null &&
false == dManager.isAdminActive(localComponentName)) {
Intent localIntent = new Intent(dManager.ACTION_ADD_DEVICE_ADMIN);
localIntent.putExtra(dManager.EXTRA_DEVICE_ADMIN, localComponentName);
localIntent.putExtra(dManager.EXTRA_ADD_EXPLANATION,
context.getResources().getString(R.string.device_admin_explanation));
startActivityForResult(localIntent, ActivityResult);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
//用于判断是否startActivity成功，需要xml中的配置权限才能设置成功
super.onActivityResult(requestCode, resultCode, data);
Log.i(TAG, "onActivityResult,resultCode:"+resultCode);
if (-1 == resultCode) {
Toast.makeText(this, this.getResources().getString(R.string.device_admin_jihuo_success_tips), Toast.LENGTH_LONG).show();;
}
else {
Toast.makeText(this, this.getResources().getString(R.string.device_admin_jihuo_failed_tips), Toast.LENGTH_LONG).show();;
}
}
