Icicle

We all hate boilerplate codes right? We hate to have to do:

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString(AWESOME_STRING, mAwesomeString);
    outState.putInt(AWESOME_INT, mAwesomeInt);
    super.onSaveInstanceState(outState);
}

And then have to do:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState != null) {
        mAwesomeString = savedInstanceState.getString(AWESOME_STRING);
        mAwesomeInt = savedInstanceState.getInt(AWESOME_INT);
    }
}

This is familiar Right?

Icicle does all the hard work for you. It automagically (I love that word too) saves and restore your instance state.

What's new in version 1.0.0-alpha

Please check the Change Log for what's new

Setting up

  • Add APT to your project-level build.gradle file
buildscript {
    repositories {
        jcenter() // Also available in maven central
    }
    dependencies {
        ...
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}
  • Add icicle and icicle-processor to your app-module-level build.gradle file
apply plugin: 'com.neenbedankt.android-apt'

dependencies {
    apt 'com.segunfamisa:icicle-processor:1.0.0-alpha'
    compile 'com.segunfamisa:icicle:1.0.0-alpha'
}

Usage

Using Icicle is simple. Annotate the field variables you wish to persist the state with @Freeze , call Icicle.freeze() when you want to save, and call Icicle.thaw() when you wish to restore from the state.

@Freeze
int mAwesomeInt;

@Freeze
String mAwesomeString;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Icicle.thaw(this, savedInstanceState);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    Icicle.freeze(this, outState);
    super.onSaveInstanceState(outState);
}

Note: Icicle works only with non-private, non-final and non-static fields.
