Export Unity Project and Build with Android Studio Tutorial (April 2022)

[@mihaithemystic2890]

Unity team is slowly building a majestic tomb stone for their engine, errors over errors, and no support at all for users who can't have internet connection all the time.

Hi. I'm stuck on install latest Android API. 2:30 My latest is Android API 33. (I notice yours is API 32...why didn't you install it ?) I get the following error: SDK Path: C:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK Packages to install: - Android SDK Platform 33 (platforms;android-33) Preparing "Install Android SDK Platform 33 (revision: 2)". Failed to read or create install properties file. Failed packages: - Android SDK Platform 33 (platforms;android-33)

[@slothgameguy]

Good question. I don’t have a super good answer for you. I think the reason I installed through android 12 and not up through API32 or in your case API33 is because I was releasing game for the latest current supported operating system, which is Android 12. I assume installing the other APIs lets you access certain attributes that will be available on future versions of the OS. For example, API33 is for Android 13, which is in Beta. My best guess is if you install the ones specifically noted as “Android ‘#’” that you’re building for a fully released OS with defined functionality. I also notice your SDK Path is your Unity folder. I actually use the android studio default folder. When I was using Unity for builds, I’d install files via Android Studio and then copy the files over to the Unity directory. Now I don’t bother building with Unity though. I hope this helps. Start by installing up to Android 12 and ignoring the ones labeled “API #” for now. Android 12 is still most current. Hope that helps.

Thanks for the reply@@slothgameguy Should I install all Android SDK's ? 2.1, 2.2.......11, 12 ? I'm trying to setup picture in picture which apparently only works in 26+....so maybe I only install Android 8.0, 8.1, 9.0, 10.0, 11.0 and 12.0. How do I change the SDK path ? Edit: Found the SDK path in the same area as the SDK's. (Just above.) Have now changed the path and things seem to be installing without errors. Still don't know if I should install ALL of the old SDK's.

[@slothgameguy]

@@anthonygirdler606 I’m fairly sure you can just install the latest, Android 12, and it will work. But it can’t hurt to install the others too. Most of the downloads of my game come from Android 10/11/12 of that gives you any clues on what OS to target. I’m not 100% sure how the Android Studio software works entirely in that regards, so might as well install the last 3-4 SDKs I’d say. If you pause my video, you can see which ones I installed and mimic that for now I think and be ok.

Everytime I go to build, i always get a debug folder and not the apk. I also have a buildmethod error message. Im using 2021.3.25

Please help me I can't export unity project from unity But if i export my unity project from unity to android studio Can I upload it to Google play?

[@slothgameguy]

Yes. Android studio app bundles are for Google Play. You will take the resulting build and upload that via the Google Play Console.

[@SaviorsVoiceNYC]

this amazinggggggg

[@anthonygirdler606]

At 4:30 you've said we should find android:exported="true" in a couple of places in the manifest. I'm pretty sure I've followed all of your steps. (export, open in android studio, install android 12 sdk, upgrade gradle, delete enableR8 ) and I don't have this. You said "If your project has been upgraded" What project are you referring to and how do I upgrade it ? The application seemed to build anyway...so....does it matter ?

[@slothgameguy]

If you open AndroidManifest.xml in your project, this is where you can find the android:exported=“true” code. It will only show up for the lines of code that are , , and . All others won’t have the “android:exported” code. So if your project is compliant with Android 12, you can open the manifest and find a section labeled and it should also say “android:exported=“true””. If it doesn’t it’s not compliant and likely won’t run on an android 12 device. Note that if you don’t have , , or sections anywhere in your AndroidManifest.xml, android:exported=“true” will not be used.

[@glizzy5154]

@@slothgameguy so do we have to start over again at the SDK part and have a it 11 or before then? how do I make it so that Android 12 works with my project

[@slothgameguy]

@@glizzy5154 you’ll probably have to google that part because I don’t have a good answer for you. I’ve always had it work correctly by installing the SDK prior to importing the project and then I go through the video steps. I don’t think you want to import project without having android studio up to date with the correct SDKs installed, so do that first before attempting the project import and build.

[@glizzy5154]

@@slothgameguy what happens when I continue to build the apk when the export isn't there?

[@slothgameguy]

@@glizzy5154 If you open AndroidManifest.xml in your project, and android:exported=“true” lines aren’t there for the the , , and sections, and you choose to build the app bundle anyways, that app bundle will not be supported on Android 12 devices. So when someone downloads your game from the play store and tries to run the app on an Android 12 device, it’ll just crash.

[@ahmedelbehiry1638]

thank you,this is very useful

[@Renagade01]

Do you have a video on how to call different scenes for like example i have this multipple buttons and each buttons is dedicated to start a scene from the apk? how to do that ?

[@challengedollar2880]

hey sloth guy, thanks for this, however when i export from unity and import , it doesnt give me the option to use android studio sdk or project sdk, how do i get that?

[@cliff7282]

How can I add Activities and navigate with intents between them?, This isn't a normal android project and some libraries missed. And if this is possible, how can I update my unity project not doing again all the work for the new screens?

[@patrickjansenD]

How about the symbols and mapping files which Unity normally generates? Does that require extra steps in AS?

[@slothgameguy]

I’m not sure, to be honest. That’s more in depth that I personally went.

I’m not an expert, I’ve just found this method works. My only suggestion is to make sure you follow the video tutorial exactly. I’m not experienced enough to troubleshoot errors though, sorry.

I keep on getting this error in android studio: This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 2021.1.1 or newer. what should i do

I’m sorry, I have no idea. Never seen this error before. You could try backing up your project first, then upgrading your Unity to one of the newer versions. Please backup your project first before attempting any Unity version upgrades!

My unity game not build using Android studio unity game version 2017

[@space_orphan]

I noticed in the unity project settings you have ticked "Custom Main Manifest". I haven't set up a custom manifest, and I noticed my manifest looks very different from yours. I don't have an "Activity" line, for example. Is this an issue?

[@slothgameguy]

Should be I don’t think. I tried to setup a custom manifest when I first encountered this issue. What ultimately gets populated in your exported manifest is also based on a lot of game options. Just use what Unity generates on export and follow the video and I think you should be ok.

Hi, i have a question: I have a android studio project and i wanna import to this project one unity exported project, and I wanna use that in my android studio project. Can I?

Sorry, I’m not familiar enough with Android Studio to know if that’s possible.

[@nikhilkadam2717]

Hello, I am trying to integrate a project from a unit as a library into a native android project. The unity project uses video files. When exporting, everything is exported and works fine except for video files. For some reason they are not exported along with the rest and therefore are not displayed in the scene. Any solution for that??

[@slothgameguy]

I’m not 100% sure, but maybe try using a different video file? It’s possible the android environment doesn’t support some file types. What is the file type now?

does it work for unity 2019.4.3 lts project ? because I can only find export project and not export app bundle check box in 2019.4.3 build setting

[@phyohtet6480]

Please help me

[@slothgameguy]

I have no clue if it works on 2019 version. If I were you, I’d backup your project and then try to upgrade it to use a newer version of Unity (such as 2021.3.10f1). As far as I can tell, the “export app bundle” check box is necessary and google play store needs the .aab file (android app bundle) of your game from android studio to work. Hope that helps.

building unity project for iOS devices is super convenient and easy but android is always a pain in the a** (

[@populargamesonline]

Great tutorial, i have some questions, never used Android studio, i love to use unity 2019.4.6 version for my games but unfortunately it does not support to build for android 12, every time i try i got errors. Tried everything but it needs new build tools and everything that is not supported. Can i export project with 2019.4.6. and try to build with android studio like in your video? Hope it will update all required files, because i realy have many projects and im afraid that if i update my Unity it will mess up my projects. If Android studio can do that then i will use this method and my projects will be safe.

[@slothgameguy]

It should work. I only started using android studio because of this issue, I think this tutorial should cover everything you need to get it working. Android studio looks hard, but it’s easier than you think and you’re using very little of its full functionality.

@@slothgameguy Tnx i realy need to start this, hope android studio will solve compatibility problems that i have with unity and all thos error mesages.
