在
myActivity
中:
AdminReceiver a = new AdminReceiver();
a.onDisableRequested(getApplicationContext(), getIntent());
AdminReceiver
:
public class AdminReceiver extends DeviceAdminReceiver{
static DevicePolicyManager dpm;
static ComponentName devAdminReceiver;
public CharSequence onDisableRequested(final Context context, Intent intent) {
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startMain); //switch to the home screen, not totally necessary
lockPhone(context, "pass");
//Log.i(TAG, "DEVICE ADMINISTRATION DISABLE REQUESTED & LOCKED PHONE");
return "haha. i locked your phone.";
}
public static boolean lockPhone(Context context, String password){
devAdminReceiver = new ComponentName(context, AdminReceiver.class);
dpm = (DevicePolicyManager)context.getSystemService(Context.DEVICE_POLICY_SERVICE);
boolean pwChange = dpm.resetPassword(password, 0);
dpm.lockNow();
return pwChange;
}
在AndroidManifest
中:
<receiver android:name=".app.AdminReceiver"
android:label="@string/app_name"
android:description="@string/hello_world"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data android:name="android.app.device_admin"
android:resource="@xml/deviceadmin" />
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
实际上我真的很困惑,它是如何工作的。请帮助我,我真的需要它来完成我的最终项目,如果没有固件修改,在Android中是不可能的。 有关进一步的管理策略,请参阅代码 或 在AndroidL push deviceower.xml中,这将使您的应用程序成为设备所有者,因此您可以应用该策略,但前提是设备应被损坏
