JarCastingasyncop
A very helpful framework for asynchronous operation related to an Activity or Fragment for Android application
How to use
With Android Studio add dependency:
compile 'com.github.mguidi.asyncop:asyncop:1.0.0'
Define your async operation extending the AsyncOp Class:
public class LongOp extends AsyncOp {
@Override
public Bundle execute(Context context, Bundle args) {
Bundle result = new Bundle();
// define your operation here
return result;
}
}
Map your operation with an action in your Application class:
public class Application extends android.app.Application {
@Override
public void onCreate() {
super.onCreate();
AsyncOpManager.getInstance(this).mapOp("long_op", LongOp.class);
}
}
Execute the operation inside an Activity or a Fragment
public class MyActivity extends ActionBarActivity implements AsyncOpCallback, View.OnClickListener {
private AsyncOpHelper mOpHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
// initialize the Async op helper on the onCreate
mOpHelper = new AsyncOpHelper(this, savedInstanceState, this);
findViewById(R.id.btnHello).setOnClickListener(this);
}
@Override
protected void onResume() {
super.onResume();
mOpHelper.onResume();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mOpHelper.onSaveInstanceState(outState);
}
@Override
protected void onPause() {
super.onPause();
mOpHelper.onPause();
}
@Override
public void onAsyncOpFinish(int idRequest, String action, Bundle args, Bundle result) {
if (action.equals("long_op")) {
// handle the result here
}
}
@Override
public void onAsyncOpFail(int idRequest, String action) {
if (action.equals("long_op")) {
// hadle the operaion fail here
// the onAscynOpFail is called only in the case that your async op was running when the system killed it
}
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btnHello) {
// define a bundle with the async op params
Bundle args = new Bundle();
// execute the async op mapped with the action
mOpHelper.execute("long_op", args);
}
}
}
