Android Studio Simple Installation Way
The release is available in both the canary channel and the dev channel, so you can check for updates via Help > Check for Update... (on OSX, look in the Android Studio menu). This will download and install a patch rather than download a full IDE image. For all older other versions you will need to install it from scratch by installing one of the below .zip files.
Windows: https://dl.google.com/dl/android/studio/ide-zips/1.0.2/android-studio-ide-135.1653844-windows.zip (235 MB)
Mac: https://dl.google.com/dl/android/studio/ide-zips/1.0.2/android-studio-ide-135.1653844-mac.zip (233 MB)
Linux: https://dl.google.com/dl/android/studio/ide-zips/1.0.2/android-studio-ide-135.1653844-linux.zip (233 MB)
We don't have installer builds for this version (at least not yet). Just use the installers for 1.0.1 and then Check For Updates within the IDE.
