我正在尝试通过使用 COSU(企业拥有的一次性使用)功能使 Unity 应用程序进入信息亭模式。
我的计划是首先使用 Android 来让事情正常运行,所以我按照Google Code Labs提供的教程进行操作
完成这项工作后,我的计划是弄清楚如何将其集成到我的 Unity 项目中。我关注 了这个 youtube 视频,该视频展示了如何制作一个可以从 Unity 调用的插件。
当我构建我的项目时,我尝试执行以下命令
adb shell dpm set-device-owner com.modalvr.unityplugin/.DeviceAdminReceiver
但是,我不断收到以下错误
Error: Unknown admin: ComponentInfo{com.modalvr.unityplugin/com.modalvr.unityplugin.DeviceAdminReceiver}
我想知道 Unity 是否没有正确地将 AndroidManifest.xml 文件合并在一起。这是我的插件中的 AndroidManifest.xml 文件。
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.modalvr.unityplugin">
<application android:allowBackup="true" android:label="@string/app_name" android:supportsRtl="true">
<receiver
android:name="com.modalvr.unityplugin.DeviceAdminReceiver"
android:description="@string/app_name"
android:label="@string/app_name"
android:permission="android.permission.BIND_DEVICE_ADMIN">
<meta-data
android:name="android.app.device_admin"
android:resource="@xml/device_admin_receiver" />
<intent-filter>
<action android:name="android.intent.action.DEVICE_ADMIN_ENABLED"/>
<action android:name="android.intent.action.PROFILE_PROVISIONING_COMPLETE"/>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>
我将它和 classes.jar 文件复制到 Unity 的 Assets/Plugins/Android/libs 文件夹中
我能够成功调用插件中的函数,因此插件似乎设置正确。
作为参考,这是我调用插件的 C# 代码
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class LockManager : MonoBehaviour {
#if UNITY_ANDROID
private AndroidJavaObject playerActivityContext = null;
#endif
public void SaveContext() {
#if UNITY_ANDROID
// First, obtain the current activity context
using (var actClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
playerActivityContext = actClass.GetStatic<AndroidJavaObject>("currentActivity");
}
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
plugin.CallStatic<bool>("setContext", playerActivityContext);
#endif
}
public void LockButtonClicked() {
#if UNITY_ANDROID
SaveContext();
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
bool retVal = plugin.CallStatic<bool>("lock", 7);
#endif
}
public void UnlockButtonClicked() {
#if UNITY_ANDROID
SaveContext();
var plugin = new AndroidJavaClass("com.modalvr.unityplugin.PluginClass");
bool retVal = plugin.CallStatic<bool>("unlock", 7);
#endif
}
}
这是定义这些函数的 java 类。
package com.modalvr.unityplugin;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
public class PluginClass {
private static Context context;
public static boolean setContext(Context ctx) {
context = ctx;
return true;
}
public static boolean lock(int number) {
Log.d("SOME TAG", "onReceive Lock");
Activity activity = (Activity) context;
activity.startLockTask();
return true;
}
public static boolean unlock(int number) {
Log.d("SOME TAG", "onReceive Unlock");
Activity activity = (Activity) context;
activity.stopLockTask();
return true;
}
}
看起来 Unity 生成了 2 个 XML 文件,并将其放入 Temp/StagingArea
AndroidManfist.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ModalVR.KioskPluginTest" xmlns:tools="http://schemas.android.com/tools" android:versionName="1.0" android:versionCode="1" android:installLocation="preferExternal">

<application android:theme="@style/UnityThemeSelector" android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="false" android:isGame="true" android:banner="@drawable/app_banner">
<activity android:name="com.unity3d.player.UnityPlayerActivity" android:label="@string/app_name" android:screenOrientation="fullSensor" android:launchMode="singleTask" android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale|layoutDirection">

</activity>
</application>
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="25" />
<uses-feature android:glEsVersion="0x00020000" />
<uses-feature android:name="android.hardware.touchscreen" android:required="false" />
<uses-feature android:name="android.hardware.touchscreen.multitouch" android:required="false" />
<uses-feature android:name="android.hardware.touchscreen.multitouch.distinct" android:required="false" />
</manifest>
和 AndroidManifest-main.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ModalVR.KioskPluginTest" xmlns:tools="http://schemas.android.com/tools" android:installLocation="preferExternal" android:versionName="1.0" android:versionCode="1">
<supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity="true" />
<application android:theme="@style/UnityThemeSelector" android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="true">
<activity android:name="com.unity3d.player.UnityPlayerActivity" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="unityplayer.UnityActivity" android:value="true" />
</activity>
</application>
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="25" />
</manifest>
在这两个文件中,我都看不到我的 Android 插件 AndroidManifest.xml 的内容,我想这就是问题所在。我需要做些什么来合并清单文件吗?
为了完整起见,这里是
DeviceAdminReceiver.java
package com.modalvr.unityplugin;
import android.content.ComponentName;
import android.content.Context;
/**
* Handles events related to the managed profile.
*/
public class DeviceAdminReceiver extends android.app.admin.DeviceAdminReceiver {
private static final String TAG = "DeviceAdminReceiver";
/**
* @param context The context of the application.
* @return The component name of this component in the given context.
*/
public static ComponentName getComponentName(Context context) {
return new ComponentName(context.getApplicationContext(), DeviceAdminReceiver.class);
}
}
提前感谢您的帮助。约翰·劳里
