从Unity3D代码启动android服务

在我的 Android Unity3D 应用程序中，我需要启动一个服务，该服务将在后台运行。我不知道我该怎么做。方法启动服务()必须在活动上调用，但我不知道如何将当前的统一活动从统一脚本传递到我的 android 插件。我还没有找到任何方法以静态方法获取活动并运行启动服务() in it.

据我了解的顺序，我需要获取主要的 Unity3D 活动并从中启动服务。

我的班级应该调用该服务。

public final class StatusCheckStarter {

    public static void StartCheckerService()
    {
        startService(new Intent(this, CheckService.class));
    }
}

此代码不起作用，因为“无法解析方法startService”并且我没有任何可传递的内容this争论。我需要获取当前的活动。

以下是两种发送方式ActivityJava 插件的实例/引用doesn't使用onCreate函数或扩展自UnityPlayerActivity.

Method 1: Send Activity参考once然后将其存储在Java中的静态变量中以供重复使用：

Java:

public final class StatusCheckStarter {

    static Activity myActivity;

    // Called From C# to get the Activity Instance
    public static void receiveActivityInstance(Activity tempActivity) {
        myActivity = tempActivity;
    }

    public static void StartCheckerService() {
        myActivity.startService(new Intent(myActivity, CheckService.class));
    }
}

C#:

AndroidJavaClass unityClass;
AndroidJavaObject unityActivity;
AndroidJavaClass customClass;

void Start()
{
    //Replace with your full package name
    sendActivityReference("com.example.StatusCheckStarter");

   //Now, start service
   startService();
}

void sendActivityReference(string packageName)
{
    unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    unityActivity = unityClass.GetStatic<AndroidJavaObject>("currentActivity");
    customClass = new AndroidJavaClass(packageName);
    customClass.CallStatic("receiveActivityInstance", unityActivity);
}

void startService()
{
    customClass.CallStatic("StartCheckerService");
}

Method 2: Send Activity参考文献each函数调用。

Java:

public final class StatusCheckStarter {

    public static void StartCheckerService(Activity tempActivity) {
        tempActivity.startService(new Intent(tempActivity, CheckService.class));
    }
}

C#:

void Start()
{
    //Replace with your full package name
    startService("com.example.StatusCheckStarter");
}

void startService(string packageName)
{
    AndroidJavaClass unityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject unityActivity = unityClass.GetStatic<AndroidJavaObject>("currentActivity");
    AndroidJavaClass customClass = new AndroidJavaClass(packageName);
    customClass.CallStatic("StartCheckerService", unityActivity);
}

Note: 您必须更换com.example.StatusCheckStarter与您的完整包StatusCheckStarter class.
