java - 通过 Unity/Java 插件启动 Android 应用程序

Question

我正在尝试通过插件将我的 Unity 项目连接到 Java，以便启动另一个应用程序，但尝试没有成功。

统一(C#):

public void AndroidCallNonStatic() {
    using (AndroidJavaClass javaClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
        using (AndroidJavaObject activity = javaClass.GetStatic<AndroidJavaObject>("currentActivity")) {
            object[] targs = new object[1] { "org.mozilla.firefox" };
            activity.Call("nonStaticMethod", targs);
        }
    }
}

Java(安卓):

import com.unity3d.player.UnityPlayerActivity;
public class Main extends UnityPlayerActivity {

    public static Context mContext;
    public static PackageManager mManager;

    @Override
    protected void onCreate(Bundle bundle)
    {
            super.onCreate(bundle);
            mContext = this;
            mManager = getPackageManager();
    }

    public void nonStaticMethod(String s)
    {
            Log.d("TAG","nonStatic method was called");
            launchApp(s);
    }

    public static void StaticMethod(String s)
    {
            Log.d("TAG","Static method was called " + s);
            launchApp(s);
    }

    public void launchApp(String packageName)
    {
        Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
        if (intent != null)
        {
            // Activity was found, launch new app
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
        }
        else
        {
            // Activity not found. Send user to market
            intent = new Intent(Intent.ACTION_VIEW);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setData(Uri.parse("market://details?id="+packageName));
            startActivity(intent);
        }
    }

}

有人可以帮我解决这个问题吗？我已经用尽了我的 Android/Unity 知识，但无法理解为什么它不起作用。我的想法是它与包名称有关。

您可以直接在 C# 中从 Unity 启动 Android 应用程序:

public void LaunchApp(String packageName)
{
    AndroidJavaClass unityPlayer;
    AndroidJavaObject currentActivity;
    AndroidJavaObject packageManager;
    AndroidJavaObject launchIntent;

    unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
    packageManager = currentActivity.Call<AndroidJavaObject>("getPackageManager");
    launchIntent = packageManager.Call<AndroidJavaObject>("getLaunchIntentForPackage", packageName);
    currentActivity.Call("startActivity", launchIntent);
}
