#GDG Android in Berlin brainstorming session

---

On November 27, 2013 I was asking the brilliant Android developers at GDG Android in Berlin for their favorite libraries that make their lives easier and should be included in every newly developed app.

This is the list of libraries we collected during this 10 minute session.

Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle

import android.annotation.TargetApi;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;

  private Paint paint = new Paint();
  private Path path = new Path();
