有没有办法阻止Android应用被删除？

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

    <uses-policies>
       <force-lock />
       <disable-keyguard-features />
    </uses-policies>
</device-admin>

   <application ... >
       <activity android:name=".MyLockedActivity"
            android:lockTaskMode="if_whitelisted"
            android:excludeFromRecents="true">
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

DevicePolicyManager devicePolicyManager = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
ComponentName adminComponentName = new ComponentName(this, MyAdminReceiver.class);
devicePolicyManager.setLockTaskPackages(adminComponentName, new String[]{getPackageName()});
startLockTask();
