Question by mabit · Dec 26, 2011 at 08:43 AM · androidremoteappworking

Unity Remote for Android not working (solution)

I have seen a lot of requests for people looking for help getting the Android Remote working.

I have been at it for a few hours to get it working on my new tablet. So here is a guide to getting it working.

Follow these steps and you should have no problems on any device (famous last words).

Step 1 - Download Android SDK

Step 2 - In the SDK installer ensure you install "Google USB Drivers"

Step 3 - Go to device manager and make sure your device has its drivers installed. You can get more help here. http://developer.android.com/sdk/win-usb.html

Step 4 - In Unity under preferences set the path to the Android SDK. C:\Program Files (x86)\Android\android-sdk or something similar.

Step 5 - Close Unity

Step 6 - On your android device ensure that in Application Settings that USB Debugging, Stay Awake and Allow Mock Locations are all enabled.

Step 7 - Connect via USB and launch the remote app.

Step 8 - Launch Unity

Step 9 - Run your game in the editor

Step 10 - Enjoy

Each time you restart the Unity Remote app you must restart Unity or the app will not pick it up. If I am in for a long dev session I plug in device and run remote and then begin work. Means I dont have to keep restarting Unity.

I hope this helps everyone who has a problem with Unity Remote on Android.

First I found that "Unity Remote" is actually an app on the Google Play Store. But still no luck. I believe my drivers and firewall are all fine but no way to test. Is it working with the without Unity Android license?

It seemed that the drivers where not correctly installed even though the Google Drivers were marked as working. It would be nice to have every version of Unity being able to check if the phone USB is correctly setup. Something like a red/green light or whatever.

After that, I didn't have to restart Unity which is really good and the Android displays the game screen.

It's not always the best idea to install google's USB drivers. for some phones only the manufacturer's drivers will enable the use of USB debugging. If you want it to work for your phone, just search for "setting up ADB on DEVICENA$$anonymous$$E" and you will probably find what you need to do. If ADB see's your device, it should work in Unity.

a simple check is to run "adb.exe" that comes in platform-tools in the sdk from command line as "adb devices" if you see something listed, then you are good to go (in theory).

Adb working? check. Launch unity remote, check. Launch Unity and play your game.

Would it work on Touch screen $$anonymous$$onitors? $$anonymous$$onitors?

Thank you! I installed the Android SD$$anonymous$$, downloaded the remote app, but couldn't get it working until I read this. I wasn't starting the remote app BEFORE Unity. That fixed it. Thanks for writing this up!

Thanks!! had my phone and tablet working with my mac, but couldn't get it to work in windows 7. Didn't think that the USB drivers needed to be installed manually since windows installed them when I first plugged in the devices!!

After much frustration and hours of trying literally everything possible, this is the solution that worked for me: This IS a lengthy and annoying process, but follow these resources in order, and make sure you follow EVERY step (especially the drivers installation in the last reference) and get it working:

  1. https://youtu.be/9R8dVJr6Asw?t=73 - old video, but the process is still the same if you NEVER have set this up before

  2. https://developer.android.com/studio/run/oem-usb.html#Drivers - find and install the OEM/driver for your phone - if you dont know this, its the brand/company that made your phones model, it will normally be at the top, bottom, or back of the device

  3. https://developer.android.com/studio/run/oem-usb.html - follow the steps for your Windows OS

  4. http://answers.unity3d.com/questions/198853/unity-remote-for-android-not-working-solution.html - confirm you did ALL these steps, in relation to the video link I included

After this, test it every time in this order:

  1. Close Unity (on your computer), and Unity Remote 5 (on your phone), and disconnect your USB

  2. Connect your USB to your device

  3. Launch Unity Remote 5

  4. Launch Unity (your desired project)

  5. Hit "Play" in the Editor

Good luck!

Answer by Ricachet · Oct 14, 2017 at 08:40 PM

Some people may have missed this but with my Samsung Galaxy S8 and also this nvidia shield tablet i have, you have to approve the machine you're connected too over USB for USB debugging. Connecting to UNITY alone does not trigger this.

To get this to trigger for me DEFINITELY, i had to run an app using Android Studio. You can just click thru the wizard to create a small Hello World app that u can run on your device instantly.

Ensure the Device Manager comes up when you click Run, it will try to then detect your connected USB Device. Once you accept your machine for USB debugging, you can close the test app and close Android Studio. Go to Unity and then launch Unity Remote 5. Doing this Worked for me, After doing the pinned steps so please upvote this for peeps who have tried all but this.

Answer by Trys10Studios · Oct 20, 2017 at 12:43 AM

Okay so I know this is silly but this was my issue.

I had forgot to point to the folder for the SDK in the External Tools.

If you go to Edit > Preferences > External Tools, assuming you have everything else installed correctly, under Android you should have 3 slots in Unity 5, at least I do. Just make sure to browse for the SDK folder, in my case it was C:/Users/owner1/AppData/Local/Android/sdk

I restarted Unity 5, exited the Unity 5 remote on the Android, disconnected the Android, plugged the Android back in, turned Unity 5 remote back on, opened Unity 5 on my computer, pushed play and voila! Victory is mine!

I gave up on this feature a couple years back because I couldn't get it, I was determined to get this working this time lol. Hopefully this helps someone. BTW I used Quill18creates video https://www.youtube.com/watch?v=yLFBu-VlBIw&t=1160s to do most of the setup (a bit dated but it works if you have a basic idea of how to navigate Windows), although if you install the Android Studio, you need to make sure you install the SDK manager by opening the Android Studio App, he suggests you don't have to during install but if you don't you won't install the manager. My device wasn't getting recognized until I did this. I overlooked the External Tools section and just so happened to be watching something unrelated and it hit me. So essentially I had to fix two problems.

As a side note, the graphics of my game are terrible on the phone lol, at least it seems up to about 5 units away, Here comes the optimization portion.

Answer by CaJerry87 · Dec 04, 2017 at 06:17 AM

I'm spamming my solution to the first few empty questions on google that are like this, in hopes that this may help someone else.

I went through A LOT to get this to work, first, here's what I tried(not the solution) but did help(and are solutions I feel are important to check):

1. I also have Android Studio so I assumed the sdk & google usb driver were installed. (wrong)
2. Everything was configured (Everything was set to android, sdk/jdk folders were on the money, phone debug mode was on. yadda yadda yadda)
3. Setting the adb path was fun. And is actually a clue to our solution.
4. This idea came to me after watching yet another setup video, this one was N3K EN's Mobile to Editor tutorial. At 1:25 he says something I couldn't let go of. And to my surprise it is an interesting conclusion I feel others should consider testing. This conclusion is that: IF YOUR DEVICE CANNOT BUILD, UNITY REMOTE 5 WON'T WORK. Why all the caps?...Troubleshooting issues for Unity Remote 5 are the SAME as troubleshooting BUILD issues.

Solution
With the aforementioned clues, I managed to discover that there is more than one usb debugging option. If you go to your Tethering & Networks setting in the Networks tab on your phone Settings(Settings>Networks,>Tethering & Networks) you might see a "USB Tethering" option. If this is off, the computer may not be recognizing your device, meaning you may be receiving "no devices found" errors when trying to build. Coincidently, if your adb isn't listing your device, this option could be the cause as well.

Hope this Helps...
