I have updated my android studio version to 2.2 and I was receiving error on project startup:
Gradle project refresh failed. So I have searched about the problem and installed the Java SE Development Kit 8u101 and set JDK location to it. After doing this error appeared :
Information:Gradle tasks [:app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources] Error:Failed to complete Gradle execution. Cause: unknown. I am stuck with this gradle execution error. I have uninstalled the android studio which I have updated and installed the new one. I am also facing the above issues in newly installed version of android studio 2.2. For now JDK location
C:\Program Files\Java\jdk1.8.0_101 And inside gradle.properties
org.gradle.jvmargs=-Xmx256m My system configurations are :
Processor -> intel core i3, RAM -> 4 gb, OS Type -> 32 bit Windows 7 Ultimate OS
Gradle console with --stacktrace --debug:
