BubblePin

Java

Library

There are several libraries used in this application, Let me introduce those indiviudally.

• Set up with Parse, you should apply for your own key, you can get access by Connect your app to Parse

• Set up with Google Play Service with com.google.android.gms:play-services:7.0.0 which includes the Google Maps Android API, you can get the help from Setting Up Google Play Services

  • Notice that if your want to compile the code, you should Obtain an API key, the Key in my code is not work for you. You can apply for the Key from Google Developers Console
  • Another thing keep in mind is that you should apply two keys for diffrent purpose, one for debug, one for release

• Add the com.google.maps.android:android-maps-utils:0.3+ into build.gradle, it's a Google Maps Android API Utility Library, some function like Cluster I used in my application list here.

• Add Metaio library into your application, same as Google Map API, you should applied a unique key for you. You can get steps from Creating a new AR application

  • Notice, use the Alternate method method list in the Android Studio

• Add com.android.support:appcompat-v7:22.0.0 and com.android.support:support-v4:22.0.0 in the build.gradle under the app folder
