Add support to save current activity instance state before destruction. #77
Description
Save instance state between activity destruction/creation is really paintful and generate a lot of boilerplate code. As we do not like this approach because ((lot of code) == (lot of bug)) (and also to save my carpal tunnel), i think we could provide a solution.
Here is a classic way to handle activity instance destruction/creation :
public class SaveInstanceStateActivity extends Activity {
private int myInt;
private MyBean myBean;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (savedInstanceState != null) {
myInt = savedInstanceState.getInt("myInt");
myBean = (MyBean) savedInstanceState.getSerializable("myBean");
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("myInt", myInt);
outState.putSerializable("myBean", myBean);
}
}By introducing the @SaveOnActivityDestroy annotation the written code could be like this :
@EActivity(R.layout.main)
public class SaveInstanceStateActivity extends Activity {
@SaveOnActivityDestroy
int myInt;
@SaveOnActivityDestroy
MyBean myBean;
}And the generated code like this :
public class SaveInstanceStateActivity_ extends SaveInstanceStateActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (savedInstanceState != null) {
myInt = savedInstanceState.getInt("myInt");
myBean = (MyBean) savedInstanceState.getSerializable("myBean");
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("myInt", myInt);
outState.putSerializable("myBean", myBean);
}

When will this feature be available for download?

When someone will have implemented it, and then on the next release :) . This is an interesting and new idea, we need to discuss all the details :) .
First usable implementation of @SaveOnActivityDestroy (see issue #77)

We finally decided to use the following annotation :
