android-studio-3.0

As seen in Android Studio 3.0 (canary 3.0), we now add depedencies by declaring implementation instead of compile configuration. // Before compile 'com.android.support:appcompat-v7:25.3.1' // Currently implementation 'com.android.support:appcompat-v7:25.3.1' We can still use compile , but I would like to understand: What is the difference between implementation and compile configuration? Why do Android Gradle build change to use implementation as default? It seems like compile has been deprecated and api or implementation should be used instead.

I'm trying to build https://github.com/neural-nuts/Cam2Caption in Android Studio 3.1 Preview, but either I use very old build.gradle, or it dies with Error:Execution failed for task ':Application:packageDebug'. Execution of compression failed. this happens after doing a project clean, or a rebuild. OSX, latest most-everything. I'm using what I think is a default latest-and-greatest build.gradle classpath 'com.android.tools.build:gradle:3.0.0' ... android { compileSdkVersion 26 defaultConfig { minSdkVersion 26 targetSdkVersion 26 } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8

I attempt to compile my Android project under AS 3.0 Canary 1 (it works fine on AS 2.3.2 stable version) but failed with the following error: FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:packageInstantRunResourcesUatGoogleDebug'. > com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor; * Try: Run with --info or --debug option to get more log output. * Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:packageInstantRunResourcesUatGoogleDebug'. at org.gradle.api

I've updated Android Studio to v3.0.0 and now I cant build my project. Android Studio add .flat to resources file names on build and the build crash because it can't recognize the .flat extension. I've tried to clean the project and rebuild it but I still get this error. I don't have any idea of what could cause this. I hope someone can help me solve my problem cause since Studio can't do a successful build, it can't find my dependencies and I can't work.
