I have a problem with an old project which was developed in IntelliJ without Gradle. I wanted to migrate it to Android Studio and Gradle, but I am experiencing a lot of problems. Since the project was quite old, the old Google Play Services version was used. In Intellij I had just added libproject of the old gps to dependencies (google_play_services_5089000_r19) and everything worked fine. In Android Studio I managed to add other libraries by adding it as a library module and adding compile project(':segmentedradios') as a gradle dependency, but I just can't make gps library work. I've tried to add it as a module, but Android Studio says that "no module selected" after pointing to libroject library's directory. I also tried to add it as a gradle dependency, but I am keep getting errors like these:
error: package com.google.android.gcm does not exist
error: package com.google.android.maps does not exist
error: cannot find symbol variable GCMRegistrar
Despite I tried ~10 different solutions, the project still does not work. How to fix it?
Gradle:
apply plugin: 'com.android.application'
android {
    compileSdkVersion "Google Inc.:Google APIs:18"
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "my_package.app_name"
        minSdkVersion 14
        targetSdkVersion 18
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}
dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile files('libs/libGoogleAnalyticsV2.jar')
    compile project(':segmentedradios')
    compile 'com.google.android.gms:play-services:5.0.89'
}
