Configuring Gradle for iosched 2013 source from Android Studio

Question

Android developer noobie here.

I got the latest iosched 2013 source and resolved most of the issues and edited the Gradle file accordingly (at least I think I am on the right track).

I can now launch the app in an AVD. Mostly resolved by:

1. Running the SDK Manager and including the libraries I figured out
2. Editing the Gradle file as below.

When I go to Build > Clean Project, it says Gradle invocation completeed succesfully

But the following lines are underlined from within Android Studio:

compile 'com.google.android.apps.dashclock:dashclock-api:+'
compile 'com.google.code.gson:gson:2.+'

exclude group: 'org.apache.httpcomponents', module: 'httpclient'
compile 'com.google.apis:google-api-services-plus:+'

apply plugin: 'android'

    mavenCentral()
}

    dependencies {
        compile 'com.google.android.gms:play-services:3.+'
        compile 'com.android.support:appcompat-v7:19.1.0'
        compile 'com.google.android.apps.dashclock:dashclock-api:+' // underlined from dashclock:dashclock-api:+ 
        compile 'com.google.code.gson:gson:2.+' // underlined from gson:gson:2.+'
        compile('com.google.api-client:google-api-client:1.+') {
            exclude group: 'xpp3', module: 'shared'
            exclude group: 'org.apache.httpcomponents', module: 'httpclient' // underlined from httpcomponents', module: 'httpclient'
            exclude group: 'junit', module: 'junit'
            exclude group: 'com.google.android', module: 'android'
        }
        compile 'com.google.api-client:google-api-client-android:1.17.+'
        compile 'com.google.apis:google-api-services-plus:+' // underlined from apis:google-api-services-plus:+'
        compile fileTree(dir: 'libs', include: '*.jar')
    }

    android {
        compileSdkVersion 19
        buildToolsVersion "19.0.0"

        defaultConfig {
            minSdkVersion 10
            targetSdkVersion 19
        }
    }

Help would be most appreciated.

Thank-you!

Answer 1

Those warnings (not errors) are totally fine. In fact, I'd recommend you turning this warning off, as 90% of the time it is a false positive.

To turn off the warning, go to File -> Settings -> Inspections, and search for 'Spelling'. Untick the results, and click Ok. The warnings will disappear.

Bottom line: If there are no other errors, you should be able to build an run the application. These warnings should not prevent that.
