Starting your app on boot
实现这一目的的方法是确定你作为发射者的意愿。
<activity ...
android:launchMode="singleInstance"
android:windowActionBar="false">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Locking your app
最可靠的方式是使用一种带有Lollipop或更大程度的装置,并利用这种装置。
startLockTask
首先,你们必须把自己的东西作为装置所有人。 贵重装置必须不预设:如果你登记,你就应进行工厂重建,并加快账户登记。
您必须首先建立感化器部件。
package com.example.myapp;
public class MyDeviceAdminReceiver extends android.app.admin.DeviceAdminReceiver {
@Override
public void onEnabled(Context context, Intent intent) {
Toast.makeText(context, "Device admin permission received", Toast.LENGTH_SHORT).show();
}
@Override
public CharSequence onDisableRequested(Context context, Intent intent) {
return "are you sure?";
}
@Override
public void onDisabled(Context context, Intent intent) {
Toast.makeText(context, "Device admin permission revoked", Toast.LENGTH_SHORT).show();
}
@Override
public void onLockTaskModeExiting(Context context, Intent intent) {
// here you must re-lock your app. make your activity know of this event and make it call startLockTask again!
}
}
一旦有了未经预想的装置,你就可以从旁边发射以下指挥器(no fundamental required)。
adb shell dpm set-device-owner com.example.myapp/.MyDeviceAdminReceiver
to avoid android asking the user permissions to pin your app you must call
setLockTaskPackages
最后!
@Override
public void onResume(){
super.onResume();
DevicePolicyManager mDevicePolicyManager = (DevicePolicyManager) getSystemService(
Context.DEVICE_POLICY_SERVICE);
ComponentName mAdminComponentName = new ComponentName(getApplicationContext(), MyDeviceAdminReceiver.class);
mDevicePolicyManager.setLockTaskPackages(mAdminComponentName, new String[]{getPackageName()});
startLockTask();
}
@Override
public void finish(){
stopLockTask();
super.finish();
}
