jack-toolchain

Now release with Android Studio 2.4 Preview 4, it is now support Java 8 language features . Jack is no longer required, and need to disable Jack to use the improved Java 8 support built into the default toolchain. Now we need to disable Jack and switch to the default toolchain. How enable Java 8 features to use in android studio project? Enable Java 8 Support : To start using supported Java 8 language features, update the Android plugin to 2.4.0-alpha4 (or higher) and add the following to your module’s build.gradle file: android { ... compileOptions { sourceCompatibility JavaVersion.VERSION_1

So I update my project to use the new jack compiler, but for some unknown reason my AntiVir blocks the task transformClassesWithPreJackPackagedLibrariesForDebug It works if I disable AntiVir real-time protection. I really don't want to do that and I don't want to start putting my android project in the exception list. I am using Android Studio 2.2 and this is my build.gradle android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { minSdkVersion 21 targetSdkVersion 24 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" jackOptions { enabled true }
