Android Studio安装不适用于gradle

Question

I am absolute beginner with Android Studio (especially Gradle) and having big trouble getting Android Studio to work. I downloaded and installed the most recent version of Android Studio (0.8.0). I have set the JDK_HOME variable. However, after I create a new project, I always receive the following message:

Error:Unknown host 'jcenter.bintray.com'. 
Enable Gradle 'offline mode' and sync project.

If I try to compile the project, I get the following message dialog:

After reading a post, I manually downloaded the Gradle binaries (latest, 2.0), extracted it onto the local drive, went to Settings and set the Gradle path to the respective directory using the following:

I also tweaked the build.gradle file under the project to point to the latest Gradle 2.0 version. However, now I get the following error message:

Error:A problem occurred configuring root project 'HelloAndroidStudio'.
Could not resolve all dependencies for configuration ':classpath'.
Could not resolve com.android.tools.build:gradle:2.0.+.
Required by:
  :HelloAndroidStudio:unspecified
    Failed to list versions for com.android.tools.build:gradle.
    Unable to load Maven meta-data from     http://jcenter.bintray.com/com/android/tools/build/gradle/maven-metadata.xml.
    Could not GET 'http://jcenter.bintray.com/com/android/tools/build/gradle/maven-metadata.xml'.
    jcenter.bintray.com

Please can someone help. Being my first time with Gradle, I have been trying for so many days without any clue to the problem. Thanks.

Answer 1

Change the Gradle version to lower ones and restart the Android Studio, you may get it.

Add this in build.gradle classpath 'com.android.tools.build:gradle:1.1.0'

Change to the latest classpath in the dependencies. For AS 1.5.1 I will do like this :

buildscript {
repositories {
    jcenter()
  }

dependencies {
    **classpath 'com.android.tools.build:gradle:1.5.0'**
  }
}
