android-studio-2.4

I have updated SDK to Android O developer preview and started a simple demo with single TextView. When i included font inside res folder it started showing me Error:Execution failed for task ':app:processDebugResources'. > com.android.ide.common.process.ProcessException: Failed to execute aapt Here is my build.gradle android { compileSdkVersion 25 buildToolsVersion "25.0.2" defaultConfig { ... minSdkVersion 15 targetSdkVersion 25 } } Note : I am using Android Studio 2.4 Preview 3 If i remove font folder from res , everything works fine This setup worked for me: compileSdkVersion 'android-O'

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
