How to install apk from code?

[fbdbdfb]

Apk downloads normally, but when installing starts, 2d system window pops up so i can't do anything. How it can be fixed? Help please

This is installing script.

        AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
        AndroidJavaObject unityContext = currentActivity.Call<AndroidJavaObject>("getApplicationContext");

        string packageName = unityContext.Call<string>("getPackageName");
        string authority = packageName + ".provider";

        AndroidJavaClass intentObj = new AndroidJavaClass("android.content.Intent");
        string ACTION_VIEW = intentObj.GetStatic<string>("ACTION_VIEW");
        AndroidJavaObject intent = new AndroidJavaObject("android.content.Intent", ACTION_VIEW);


        int FLAG_ACTIVITY_NEW_TASK = intentObj.GetStatic<int>("FLAG_ACTIVITY_NEW_TASK");
        int FLAG_GRANT_READ_URI_PERMISSION = intentObj.GetStatic<int>("FLAG_GRANT_READ_URI_PERMISSION");

        AndroidJavaObject fileObj = new AndroidJavaObject("java.io.File", apkPath);
        AndroidJavaClass fileProvider = new AndroidJavaClass("androidx.core.content.FileProvider");
        AndroidJavaObject uri = fileProvider.CallStatic<AndroidJavaObject>("getUriForFile", unityContext, authority, fileObj);

        intent.Call<AndroidJavaObject>("setDataAndType", uri, "application/vnd.android.package-archive");
        intent.Call<AndroidJavaObject>("addFlags", FLAG_ACTIVITY_NEW_TASK);
        intent.Call<AndroidJavaObject>("addFlags", FLAG_GRANT_READ_URI_PERMISSION);

        currentActivity.Call("startActivity", intent);

What do you mean by 2D system window?
Can you share a screenshot?

Also, a question to you, I'm using the exact same code that you are, but the fileProdiver returned from 

AndroidJavaClass fileProvider = new AndroidJavaClass("androidx.core.content.FileProvider");

is just returning null for me.
Could you maybe share your aar/plugin/manifest setup?

Can't do screenshot now. It's just a window on black background, that asks permission to install apk. I can't click yes/no cause controllers don't work in this mode. 

I had the same problem but i solved it by using Permission Manager. In this case i need FLAG_GRANT_READ_URI_PERMISSION, so i can't use it.

Probably you should look at https://stackoverflow.com/questions/58085899/android-10-no-activity-found-to-handle-intent
ACTION_VIEW (for APKs) and ACTION_INSTALL_PACKAGE were deprecated in Android 10. You need to switch to the PackageInstaller API.

You can try switch API and check. If you will get it work, please write a result.
