Including in your project

Add the maven repo url to your root build.gradle in the allProjects{} blocks:

  ...

  allProjects {
    repositories {
        maven { url "https://raw.github.com/Raizlabs/maven-releases/master/releases" }
    }
  }

Add the library to the project-level build.gradle, using the apt plugin to enable Annotation Processing:

  apply plugin: 'com.neenbedankt.android-apt'

  dependencies {
    apt 'com.raizlabs.android:DBFlow-Compiler:2.0.0'
    compile "com.raizlabs.android:DBFlow-Core:2.0.0"
    compile "com.raizlabs.android:DBFlow:2.0.0"
  }

Gotchas/Compatibility

For GSON and RetroFit compatibility check out #121.

Due to this library using a custom maven repo, to speed up build times when using this library, you should run in --offline mode except for when updating dependencies. To enable this setting in Android Studio, ensure the option is checked in: Preferences->Build,Executor,Deployment->Build Tools->Gradle->Offline Work

Pull Requests

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults.
2. If its a feature, bugfix, or anything please only change code to what you specify. DO NOT do this: Ex: Title "Fixes Crash Related to Bug" includes other files that were changed without explanation or doesn't relate to the bug you fixed. Or another example is a non-descriptive title "Fixes Stuff".
3. Pull requests must be made against develop branch.
4. Have fun!
