blundell / Gradle handle repos
Created Jan 20, 2014
Handle the declaration of all source code repositories in your base build file, and you don't have to worry about declaring them in any child modules. The code below would go at the top of your build.gradle, in your 'base' or 'top' build.gradle file. You don't have to add anything to child modules. You will get full repository source retrieval.
View Gradle handle repos
subprojects {
buildscript {
repositories {
mavenCentral()
maven {
url "https://oss.sonatype.org/content/repositories/snapshots"
}
maven {
url "https://github.com/novoda/public-mvn-repo/raw/master/releases"

public NavDrawerArrayAdapter(final Context context) {
super(context, android.R.layout.simple_list_item_activated_1, android.R.id.text1,
new ArrayList<String>() {{
add(context.getString(R.string.nav_drawer_section_explore));
add(context.getString(R.string.nav_drawer_section_rewards));
add(context.getString(R.string.nav_drawer_section_offers));
add(context.getString(R.string.nav_drawer_section_events));
