You may encounter "unable to run mksdcard SDK tool" when you are installing android studio in 64 bit ubuntu os because studio requires some 32 binaries. To overcome this error finish and close Android Studio & go to terminal and run sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6 . Once installation is completed for these binaries again go back to step 6 and resume installation process.

Notes

• If you have already installed JDK and still getting then make sure you have set JAVA_HOME in your System Variables . You can check this answer on how to setup one.

• There are, however, known stability issues in Android Studio on Mac when using JDK 1.8. Until these issues are resolved, you can improve stability by downgrading your JDK to an older version (but no lower than JDK 1.6).

• While the Android Studio download completes, verify which version of the JDK you have: open a command line and type javac -version . If the JDK is not available or the version is lower than 1.8, download the Java SE Development Kit 8.

• If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following commands:

  sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5 libbz2-1.0:i386 lib32stdc++6

• If you are running 64-bit Fedora, the command is:

  sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686

Problem with downloading

• If you would face any issue like message that your system is not compatible with Android Studio (it may happen when you're using web browser different than Chrome) download Android Studio from: http://tools.android.com/

That's it!
