Android Studio 2.0 - NoSuchAlgorithmException: SHA256WITHDSA Signature not available

I'm running Android Studio 2.0 Preview 3b and trying to use "Generate Signed APK..." from the Build menu.

I get the following error Messages pane:

:wear:packageRelease FAILED
FAILURE: Build failed with an exception.
* Exception is:

Android Studio is using JRE 1.7.0_55-b13 x86_64.

I see the try using a newer JVM to build your application. suggestion. Will it help to upgrade Java? Or how can I resolve this?

I haven't seen anywhere (e.g. http://tools.android.com/recent) that a Java upgrade is needed for Android Studio 2.0.

Solution

  • I just got the exact same problem with Android Studio 2.0 (the stable release) with com.android.tools.build:gradle:2.0.0.

    Even though my IDE was running with JDK 1.8_u77, I still had the problem.

    To fix it, go to Project Structure > SDK Location > make sure JDK location is set to a (at least 1.8) recent JDK ! (at the time of this post, the latest is 1.8_u77).
