I need to zip-align an APK file after I re-signed it with a specific cert. Everything worked fine with keytool and jarsigner. However, the zipalign tool was not installed with Java SDK 8 Update 92 (inlcuding JRE in same version). I am running Windows 10 x64.

Also, the Android Studio IDE did not come with zipalign tool. I crawled many forums and also stackoverflow but did not find any solution. In former times, zipalign was always installed with Java JRE in BIN directory.

Where do I get the zip-align tool?

Thanks for any help!

As far as I'm aware zipalign is an Android specific tool, not a Java tool. Why would it be included in the JDK/JRE? This tool is part of the Android SDK, more specifically it's part of the Android build tools.

Look in your Android SDK directory, e.g.:

~/android-sdks/build-tools/25.0.1/zipalign

Replace ~/android-sdks with the directory in which you have installed the Android SDK. Replace 25.0.1 with any of the build tools version(s) you have installed (25.0.1 is the most current right now).
