In my case, there isn't actually a data exchange at all. This is
actually setting my app's Preferences. This is the relevant code:
//////// Activity A
// Button Listeners
accountButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(A.this, B.class);
startActivityForResult(i, App.USER_CREATE);
}});
//////// Activity B
@Override
protected void onActivityResult(int request, int result, Intent i){
super.onActivityResult(request, result, i);
Log.i("B","Returning from User Create"); // Note, this line
is NEVER seen
// Just returned from creating a user
if(request == App.USER_CREATE && result == RESULT_OK){
// User has successfully registered, go back to main
screen
setResult(RESULT_OK);
finish();
}
}
// Button for B
signupButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent nextScreen = new Intent(B.this, C.class);
startActivityForResult(nextScreen, App.USER_CREATE);
}});
////////// Activity C
// Button in C
signupButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
setResult(RESULT_OK);
finish();
}});
