Installing Android SDK Command-line tools from Android SDK Manager did the job for me.

  1. Open Tools > SDK Manager
  2. From the left choose, Appearance & Behavior > System Settings > Android SDK
  3. Select SDK Tools from the top menu
  4. Check Android SDK Command-line tools and click 'apply'.

Alternative to step #1: WINDOWS: File > Settings (Ctrl+Alt+S) / MAC : Android Studio > Preferences

This fix works for Windows, Linux and Mac OS X.

If you are facing a problem in spite of the above steps, you can try upgrading your system to JDK 8. Official documentation of upgrading to JDK 8 is available here.

I'm a Mac user and I solve this issue.

This answer also helps Windows users and Linux users solve the issue from the user's feedback.

Android SDK Command-line Tools. And how?

  3. Click Android SDK
  4. Click tab of SDK Tools
  5. Check Android SDK Command-line Tools (latest)

Keep going to sign android licenses.

After Android Studio finishing install, you can do the following.

It seems you are getting a JDK exception, it happens when you does not have JAVA_HOME setted on your system variables OR you have almost setted the JDK but in the wrong folder OR you are trying to run the SDK Manager (which allows you to accept the Android Licenses) with the wrong JDK.

In case of JDK 9 or higher:

Actually, Android SDK Manager works only with Gradle compiled on version of JDK 8 for Android development, so, if you have a most-recent JDK version already setted on system variables, consider to downgrade it to the JDK version 8.

This version works fine for me:

In case of JDK 8 already installed

If you manually extracted the JDK folder to a directory, maybe you have setted it "wrong". I mean: You pointed the wrong way to the bin Java folder, but it still works. You have to set JAVA_HOME as the root of JDK, example: In the JDK zipped folder, you have to extract it and point the system variable in the unzipped folder, no directly in the bin directory, you have to point JAVA_HOME as a system variable and declare the bin folder as an executable.



In your shell configuration file:

export JAVA_HOME="/home/user/jdk1.8.0_261" export PATH="$PATH:$JAVA_HOME/bin" 


In your environment variables manager:

Then, edit the PATH variable and add a new register to it:


Actually, I don't know really how to manage JDKs in MacOS, if that is you OS, sorry :(

Hope it helps!

You need JDK 8 since the required files were removed in later versions.

Once installed you can switch between versions using

sudo update-alternatives --config java 

then select the option for JDK 8. This will also show you the location of your JDK 8 installation which you'll need for:

export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/" PATH=$PATH:$JAVA_HOME/bin
