如何使用Android-L preVIEW任务锁定？ [英] How to use Android-L preview Task Locking?

问题描述

有没有人有任务锁定在Android中l工作？他们能分享它是如何工作的一些细节？我看到下面的说明，但努力理解这一点。

Has anyone got task locking working in Android L? Could they share some details on how it works? I have seen the instructions below, but struggling to understand this.

目前，我已经做了应用程序，我想在Kiosk模式下运行。我已经看过使其成为一个启动应用程序，或使用型Surelock但新的任务锁定看起来这将是未来的最佳选择。

At the moment I have made an App that I would like to run in kiosk mode. I have looked at making it a launcher App or using Surelock but the new task locking looks like it will be the best option in future.

我需要创建的Andr​​oid L的userdebug构建？我还没有建立的Andr​​oid从源之前，我就开始寻找使构建，但我不认为源代码的Andr​​oid-L提供了吗？

I need to create a userdebug build of Android L? I have not built Android from source before, I started looking at making a build but I don't think the source for Android-L is available yet?

To set up a device owner, follow these steps:

Attach a device running an Android userdebug build to your development machine.
Install your device owner app.
Create a device_owner.xml file and save it to the /data/system directory on the device.

$ adb root
$ adb shell stop
$ rm /tmp/device_owner.xml
$ echo "<?xml version='1.0' encoding='utf-8' standalone='yes' ?>">> /tmp/device_owner.xml
$ echo "<device-owner package=\"<your_device_owner_package>\"name=\"*<your_organization_name>\" />" >> /tmp/device_owner.xml
$ adb push /tmp/device_owner.xml /data/system/device_owner.xml
$ adb reboot

我想铲除我的设备（的Nexus 7），运行Android-L preVIEW。然后我把device_owner.xml在数据/系统/我的包名。但它仍然无法正常工作，islockTaskPermited（）返回false，并调用startLockTask（）什么都不做。

I tried rooting my device (Nexus 7) running the Android-L preview. I then put a device_owner.xml with my package name in data/system/. But it still does not work, islockTaskPermited() return false, and calling startLockTask() does nothing.

推荐答案
