Gradle returns package does not exists [duplicate]

Question

I'm trying to add the gson library to my android project (I'm devloping using the Andrdoid-studio).

To add the library, I changed the AppProject/AppName/build.gradle file in this way:

buildscript {     repositories {         mavenCentral()     }     dependencies {         classpath 'com.android.tools.build:gradle:0.4'     } } apply plugin: 'android'  repositories {     mavenCentral() }  dependencies {     compile files('libs/android-support-v4.jar')     compile 'com.google.code.gson:gson:2.2.4' }  android {     compileSdkVersion 17     buildToolsVersion "17.0.0"      defaultConfig {         minSdkVersion 4         targetSdkVersion 16     } } 

It seems to work until I try to use it.

When I try to include it with:

import com.google.code.gson; 

Gradle complains affirming:

Gradle: error: package com.google does not exist

The accepted answer did not work for me, but this did:

• Download the GSON JAR file and copy it to your /libs/ folder inside your application project.

• Open the build.gradle file at the root level of your project and edit your dependencies to include the new .jar file:

  dependencies {     compile fileTree(dir: 'libs', include: '*.jar') } 

• Build -> Rebuild Project

Optionally, you can specify one or more specific JAR files with files rather than fileTree, such as: compile files('libs/google-gson-1.7.1/gson-1.7.1.jar')

One solution that might be helpful is to try Syncing Project with Gradle Files

Tools -> Android -> Sync Project with Gradle Files
