这是一个当Activity或者Fragment调用onSaveInstanceState(Bundle outState)方法时，进行数据保存的，并且可以在需要将savedInstanceState的数据进行读取的库。 详细使用可以看Simple里的代码。
build
compile 'com.sora:InstanceCoupling:1.0.1'
##使用方法 注解需要保存的字段：
@SaveField//给name属性添加一个注解
private String name;读取
//读取数据
Couple.readInstance(this, savedInstanceState);
TextView textView = findViewById(R.id.textview);
textView.setText(name);保存：
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//保存数据
Couple.saveInstance(this, outState);
