1.需求

unity生成AndroidApk，只能首次启动启动，且后续关闭后重启不再启动。

2.首次启动

在Manifest文件中如下设置：android:priority设置较高是为了保证在其他launcher前启动。

      <intent-filter android:priority="2000">
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.HOME" />
        <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>

3.关闭后apk禁用

    public void DisableSetupWizard()
    {
        const int COMPONENT_ENABLED_STATE_DISABLED = 2;
        const int DONT_KILL_APP = 1;
        AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject currentActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");

        AndroidJavaObject pm = currentActivity.Call<AndroidJavaObject>("getPackageManager");
        AndroidJavaObject component = new AndroidJavaObject("android.content.ComponentName",
                                                            "包名",
                                                            "类名");
        pm.Call("setComponentEnabledSetting", component, COMPONENT_ENABLED_STATE_DISABLED, DONT_KILL_APP);
    }
