Question

I'm trying to make a basic Google Cloud Messaging application, However, I get following error:

    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 16
    }
    buildTypes {
        release {
            runProguard true
            proguardFile getDefaultProguardFile('proguard-android.txt')
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.google.android.gms:play-services:4.0.30'
}

I am using Android Studio. Can someone help me solve the problem?

Answer 1

Make sure you have this in your SDK directory

$ANDROID_SDK_DIR\extras\google\m2repository\com\google\android\gms\play-services\4.0.30

Also upgrade your Android Studio to 0.4.3. In 0.4.2 your code will not find the symbols in java class files but will compile fine.

Answer 2

try adding this dependency in gradle:

compile 'com.android.support:support-v4:18.0.0'

or else Upgrade to Android Studio 0.4.0 or later, or clean and rebuild your project if you want to stay on 0.3.2. There's a bug in the 0.6 versions of the Gradle plugin (https://code.google.com/p/android/issues/detail?id=63366) that can cause newly-added dependencies to not get linked into your APK unless you clean your project after doing so.
