This is my Gradle:
apply plugin: 'com.android.application'
android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.googleplus_1"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        multiDexEnabled = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.google.android.gms:play-services:7.0.0'
    compile 'com.google.gdata:core:1.47.1'
}
/*
configurations {
    all*.exclude group: 'com.android.support'
}
configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
    all*.exclude group: 'com.google.android.gms', module: 'play-services'
}*/
When I Run the app I get this error:
UNEXPECTED TOP-LEVEL ERROR:
java.lang.OutOfMemoryError: Java heap space
however If I comment "compile 'com.google.gdata:core:1.47.1'" and the relevant code the error is gone.
Can you please help me out with this? Thanks
