Set up android sdk path to make android remote work что делать

If you installed the SDK when you installed Android Studio, you can find the location in the Android Studio SDK Manager. To open the SDK Manager from Android Studio, go to Tools > Android > SDK Manager or select SDK Manager in the toolbar.

To change the location of the Android SDK, in the Unity menu bar go to Unity > Preferences > External Tools.

4. Download and set up the Android NDK

If you are using the IL2CPP scripting backend for Android, you need the Android Native Development Kit (NDK). It contains the toolchains (such as compiler and linker) needed to build the necessary libraries and produce the output package (APK). If you are not targeting the IL2CPP backend, you can skip this step.

Download Android NDK version r16b (64-bit) from the NDK Downloads web page. Extract the android-ndk-r16b folder to a directory on your computer and note the location.

The first time you build a Project for Android using IL2CPP, Unity asks you to locate the folder in which you installed the Android NDK. Select the root folder of your NDK installation. To change the location of the Android NDK, in the Unity Editor, navigate to the menu: Unity > Preferences to display the Unity Preferences dialog box. Here, click External Tools.

Using an alternate Java Development Kit

Unity recommends that you use the JDK installed with the Android build tools, to ensure that you receive the correct version and configuration.

If you have manually installed the JDK and do not want to duplicate the installation, you can specify the location in the Unity Preferences window. To do this, go to Preferences > External tools and enter the directory path in the JDK field:

Preferences for Android external tools

Warning: The Android tools do not support JDK 9 or later; an alternate JDK must be version 8. Unity does not officially support versions of the JDK other than the one embedded in the Android Build Tools.

To change the JDK that Unity uses to build Android apps:

Open the Project.

In the left navigation column, select External Tools.

Uncheck JDK Installed with Unity (recommended).

In the JDK field enter the path to the JDK or use the Browse button to locate it.

This article is a continuation of our Getting Unity Remote for Android to work on Windows. If you’re here, that’s probably because you couldn’t get USB debugging to show on your Android device, and the simpler tricks we shared in our article didn’t work for you.

For ease-of-use, here are quick links to the respective sections in this article:

1. Manually setting Android file paths

24 August 2020 Update: This section was added after one of the readers from another article posted this helpful tip. It got Unity Remote working on one of my computers!

By default, if you’re using the SDK, NDK and JDK provided by Unity’s Android Build Support installation, going to Edit > Preferences > External Tools should give you the following window.

What has worked for some people (including myself), is:

1. Unchecking the JDK, SDK and NDK fields (the first three checkboxes in the red box), then;
2. Manually setting the paths to Unity’s JDK, SDK and NDK files.

Yes, we’re basically using the JDK, SDK and NDK files provided by Unity, but manually linking them to Unity instead of checking the checkboxes and allowing Unity to do it for us.

Once you uncheck each of the checkboxes, you should see a text field and a Browse button right beside. Clicking on each Browse button should automatically fill up the accompanying text field with the path to the Unity installed NDK, SDK and JDK respectively.

If clicking on the Browse button doesn’t work for you, you’ll have to find the files manually. They should be in either of these folders:

• C:\Program Files\Unity\Hub\Editor\[YOUR_UNITY_VERSION]\Editor\Data\PlaybackEngines\AndroidPlayer
• C:\Program Files\Unity\Editor[YOUR_UNITY_VERSION]\Editor\Data\PlaybackEngines\AndroidPlayer

The SDK and NDK are in the SDK and NDK folders respectively, but the JDK is in OpenJDK\Windows .

After this is done, you might also want to restart Unity Editor and Unity Remote, and then reconnect your mobile device, before trying again.

2. Installing Google USB Driver

For some computers, the Google USB Driver seems to be the magic component that gets Unity Remote working. There are two ways of installing the Google USB Driver:

For most modern computers, only (2) works, but you should give (1) a try first, as (2) requires installing Android Studio, which is more work.

a. Direct installation

To install the Google USB Driver on your computer, you will need to head to this page, click on the download link and accept the terms & conditions pop-up. The downloaded file is a ZIP, which you’ll need to unzip.

To make use of the unzipped files, you’ll need to connect your Android device to your computer and open the Computer Management application. If you can’t find it, click on Start and type in the app’s name to search for it.

When inside the application, select Device Manager and find your attached Android device under Portable Devices. Right-click and select Update driver.

Note: Sometimes you will find your mobile in Device Manager > Universal Serial Bus Devices instead of Portable Devices. Thanks to fibrizo for the heads up.

In the pop-up that appears, select Browse my computer for driver software on the window that pops up. Then, select the unzipped Google USB Driver folder (making sure to check Include subfolders) to install.

b. Through Android Studio’s SDK Manager

If the above steps do not work for you, you can also install Android Studio, then install Google USB Driver using its SDK Manager.

If the SDK Manager window does not show, you can click on Settings below it to access the same window. Then, do a search for SDK Manager to find the window (as pictured below). If you can’t access the window, check if the Android SDK Location (again, as pictured below) is set.

The SDK Manager looks like the image below. You’ll find the Google USB Driver under Android SDK > SDK Tools.

3. Setting your target platform in Build Settings

30 March 2021 Update: This section was added after one of the readers left this comment on the other article for Unity Remote.

For some readers, switching their build platform over to Android in File > Build Settings worked. Note that to do so, you’ll need to have Android Build Support installed on the Unity version you are using.

4. Setting your target platform on Unity Hub

19 June 2021 Update: This section was added after one of the readers left this comment on the other article for Unity Remote.

If setting your target platform on the editor’s Build Settings window didn’t work, you can try setting your project platform on Unity Hub before opening the project.

Refer to the GIF below to see where to find the dropdown.

5. Using Android Debug Bridge (adb)

In some cases, you’ll find that regardless of what you do, Unity Remote just doesn’t seem to work. In this case, it might be because your computer is unable to detect your Android device. adb.exe is a command-line tool included with Android SDKs, and it can help with that.

If you are using Unity 2019.1 and above, you don’t have to download anything to access adb.exe — it comes with Unity’s Android Build Support module, if you installed the Android SDK included with it. You should be able to find adb.exe in C:\Program Files\Unity\Hub\Editor\[YOUR_UNITY_VERSION]\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools , unless you installed Unity in a custom folder.

A possible alternative location for the file is C:\Program Files\Unity\Editor\[YOUR_UNITY_VERSION]\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools . Alternatively, you can search your drive for adb.exe to find the folder.

If you try clicking adb.exe to run it, you will find that nothing much happens. That’s because adb.exe is a command line application, which means you need to run it in Window’s Command Prompt to use it.

1. To open the Command Prompt, press Windows + R on your computer to open the Run dialog. Type in cmd , and instead of pressing Enter , press Ctrl + Shift + Enter to run the program as an Administrator.
2. We will need to navigate to the folder where adb.exe is in the Command Prompt before we can access the program. Type cd into the Command Prompt, followed by the path of the directory adb.exe is in, i.e. cd C:\Program Files\Unity\Hub\Editor\[YOUR_UNITY_VERSION]\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools .

Execute the adb devices command once you are in the platform-tools folder containing adb.exe . The adb devices command runs adb.exe and lists all the devices that the Android SDK is currently detecting.

If you get an output similar to the green highlighted section above, restart 1) the Unity Editor and; 2) your Unity Remote, then; 3) unplug and plugin your Android device, then try running Unity Remote again. If it still doesn’t work, try the instructions on the next paragraph.

If you don’t get an output, it means that your Android device is not being read, and this is probably what is causing Unity Remote to not work. You might want to try a different USB cable, a different USB port, or a different device altogether.

Alternatively, you can run the following on adb to restart it, and then run adb devices again.

6. Enabling other Developer Options

For some people, Unity Remote has managed to work after they’ve enabled the Stay awake option in Developer Options.

For others, it started working after they changed their USB configuration (again, in Developer Options) from MTP (Media Transfer Protocol) to PTP (Picture Transfer Protocol).

Depending on your device model, the USB configuration setting might be found in another tab instead of Developer Options.

If you can’t find the option that allows you to change your connection to PTP, take a look at this article from another site.

7. SDK, NDK or JDK installation issues

• OpenJDK installs halfway and stops without any notice. You can look at this Unity Forum topic about this issue.
• The Unity-native SDK or NDK is not compatible with the current project. If you get this, you’re just plain unlucky.

If you run into this issue, one way to go around it is to find people who have managed to get Unity Remote working on their computers and devices, or, at the very least, has a working Android Build Support module with the SDK, NDK and JDK installed.

Why? So that you can copy the SDK, NDK and / or JDK files on their Unity installation over. By the way, only copy the ones that don’t work — you probably don’t need all 3!

8. Bonus: Hiding Developer Options again

For some of you, when you’re done messing with Unity Remote, you might want to hide Developer Options again on your device. You know, what with cybersecurity being a buzzword nowadays and all.

Just head into Developer Options again, and tap the knob on the top right. This will also turn off USB debugging and set the rest of your Developer Options back to their defaults.
