Mobile Security defender------Mobile anti-theft page destruction Data & Remote lock screen

The ability to destroy data and remote lock screens is achieved by obtaining device Administrator privileges

1. First create a class that inherits Deviceadminreceiver. Look at the class name and you'll guess it's probably a broadcastreceiver. Make sure this is a broadcast subclass by looking at the source code. So you have to register on the manifest file.
View the official Android API:

<receiver android:name=". MyAdmin "android:label=" @string/description "android:description=" @string/ Label "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>

Where: description is descriptive information; label is descriptive information label;
Also create an XML directory under the resource directory to create the Device_admin_sample.xml

<device-admin xmlns:android="Http://schemas.android.com/apk/res/android">   <uses-policies>    <limit-password />    <watch-login />    <reset-password />    <force-lock />    <wipe-data />    <expire-password />    <encrypted-storage />    <disable-camera />  </uses-policies></device-admin>

2. In the Java file:

• To turn on Device management policy permissions:

  • Create a intent
    Intent Intent = new Intent (devicepolicymanager.action_add_device_admin);
  • Select the name of the control you want to manipulate
    ComponentName mdeviceadminsimple = new ComponentName (mainactivity.this,myadmin.class);
  • Activating Device Management policies
    Intent.putextra (devicepolicymanager.extra_device_admin,mdeviceadminsample);

  • Add a Description language
    Intent.putextra (devicepolicymanager.extra_add_explanation, "open permission, one click Lock screen, save home button!");

  • Complete, startactivity;
    StartActivity (Intent);

• Create a Device management policy
  Private Devicepolicymanager DPM;
  DPM = Getsystemservice (Device_policy_service);
  One-click Lock screen, set the password
  Dpm.locknow ();
  Dpm.setpassword (password value, additional added value set to 0);
  Clear Data
  Dpm.wipedata (0)//restore factory settings
  Dpm.wipedate (Devicepolicymanager.wipe_external_storage); Format SD Card

User cannot uninstall the current app because of device management mechanism (good cock appearance ~ ~)

We need to provide the uninstall function separately:

    //取消设备管理员权限    manager.removeActiveAdmin(mDeviceAdminSimple);    //卸载    Intent intent = new Intent();    intent.setAction("android.intent.action.VIEW");    intent.addCategory("android.intent.category.DEFAULT");    intent.setData(Uri.parse("package:" + getPackageName()));    startActivity(intent);
