Anyone that can help? I’ve put this problem on the back burner while creating my app which is close to being done. I’ve looked everywhere I could think online, and found a few people with the same issue and a lot of “same here” replies. Any possible solutions will be much appreciated

It’s hard to tell from the screenshot without getting the actual error message you’re seeing.

What happened when you followed the instructions for this error in the documentation?

No Android device found
If Unity cannot find an Android device connected to the system, check the following:

• Make sure that your device is actually connected to your computer - check the USB cable and the sockets.

• Make sure that your device has USB Debugging enabled in the Developer options. For more details, refer to the Android SDK/NDK Setup page.

• Run the adb devices command from the platform-tools directory of your Android SDK installation and check the output.

• If the output list is empty and you are using Windows, you may need to install the driver for ADB devices. For more details, refer to the Android SDK/NDK Setup documentation.

• If the list contains entries with the unauthorized label, you may need to authorize your computer on your device and give it permission to debug it. Check the device’s screen for the corresponding dialog.

• If the list contains your device with the device label, build your Project in Unity again.

Ok finally got mine to work. yay.

The problem for me was the SDK file (I had the same .cs 162 & .cs 83 errors)

First: In Unity : Edit > Preferences > External Tools and click Download. It should take you to:دانلود Android Studio & App Tools - Android Developers

Second: Download Android Studio NOT just the Sdk at the bottom

Third: After Download go back into unity and click File > Build Settings > Player Settings > ‘Other Settings’ (in inspector) and set the ‘Minimal API level’
to the highest setting ‘Android 7.1’Nougat’ (API level 25)’ and click ‘Build & Run’ (Not just ‘Build’)

This build will fail, but the fail pop up box will inform you what your devices API level is.(Mine is 23) Put ‘Minimal API level’ back to the original setting (Min api level) after you’ve learned your API level.

Fourth: Start ‘Android Studio’ and on the bottom right of the main screen click ‘Configure’ > ‘SDK Manager’ > ‘Appearance & Behavior’ tab > ‘System Settings’ tab click ‘Android SDK’

Fifth: Now just Check the box with the ‘API level’ your device is at and click apply to download. (Remember file path)

Sixth: Once the download is complete go back into Unity: Edit > Preferences > External Tools Beside SDK click browse and link it to the SDK folder of your API level download.
(Example: C:\Users\Anthony\AppData\Local\Android\sdk)
