StartActivityForResult

 I am using ListActivities to drill down into a hierarchy; artist,
album and song. One activity per hierarchy. So, from the main
activity  I start the ArtistActivity with the StartActivityForResult
method and when the an artist is selected I call the

protected void onListItemClick(ListView l, View v, int position, long
id) {

setResult(Activity.RESULT_OK, results);
finish();

}

to return the results. Than the main activity receives results from
the ArtistsActivity in the onActivityResult method and starts the next
hierarchy activity, AlbumActivity, in the same way as the previous
activity, on so on. It works fine except that when calling finish
method the hierarchy activity is removed from the stack. So, it makes
it impossible to backtrack to the previous hierarchy since it not
there anymore. For example, I can backtrack from AlbumActivity to
the ArtistsActivity since it has been removed from the stack.  My
question is; is there any way to leave the hierarchy activities on the
stack?

 > I am using ListActivities to drill down into a hierarchy; artist,

Instead of calling setResult()/finish() in a list item click,
startActivityForResult() the next level down in the hierarchy. Only the
leaf should call setResult()/finish() in a list item click. All branches
of the hierarchy should call setResult()/finish() in their
onActivityResult(), forwarding the leaf's result Intent along.

StartActivityForResult

 Thanks Mark, it will work. I was considering this approach. I was
hesitant for it establishes a dependency among the hierarchy
activities. I thought I might have a need to reuse the activities in
other scenarios in which I might have to select the artists/albums/
songs only without drilling down the hierarchy. I will go with your
suggestion thought.

startActivityForResult

by Pierre Henry » Sun, 28 Feb 2010 05:41:11 GMT


 Encoutered a tricky result using startActivityForResult from an
Activity

In the called Activity , I set result like that:
______________
setResult(RESULT_OK, getIntent().putExtra(getPackageName()+"values",
values));
______________________

When running the on ActivityResult, the extra has disappeared from
intent in the method *onActivityResult*

In the api doc, it is telling that package name must be used , so I
used it (see code upwards ).

So why is that ?

Create a fresh Intent (via new Intent()) and see if that helps.

 Hi Pierre, I have release a set of video android tutorials on
 http://android.voxisland.com 
and the free/sample chapter is on Intents. It should answers your
questions and provide you
some guidance to go further with Intents.
enjoy

startActivityForResult

by kypriakos » Thu, 19 May 2011 11:44:45 GMT


 Hi all,

I am writing apps for some old phones (Android 1.6). I can call
startActivity(intent) without issues but the
startActivityForResult(intent, int) fails on compile? Was this method
introduced after 1.6? How can one see what's been deprecated across
versions?

Thanks

 In the upper right corner of API page there is a scrollbox you can use to
filter the minimum API level you want to see.
Hope this helps. :)

 Great thanks - much appreciated it. But I was also asking as to
whether the
startActivityforResult() is part of the Android 1.6 API since the
compilation
fails there. Any idea?

 Excellent!  Thanks.

So the API level 4 (to which cupcake/1.6 is based on) does not have
the startActivityForResult -
which is in line with the fact that the compilation fails. Anyway
knows as to what provision
was available back then for allowing an activity to call back a
calling class? Or no such luck?
Will I need to use some kind of shared mem or a file method to pass
results back?

Thanks

 startActivityForResult has been in the API since level 1.

1.6 has it.

Here's a link to the 
documentation< http://developer.android.com/reference/android/app/Activity.html #startActivityForResult(android.content.Intent,
 
int)>.

 Huh?

 http://developer.android.com/reference/android/app/Activity.html #startActivityForResult(android.content.Intent, 
int)


Since API level 1 - i.e. Android 1.0.

Perhaps you could post a code snippet showing the compile error.

 That's what I said too - huh? ;)

        Intent intent = new Intent();
        intent.setClass(androidContext,
mysnapPic2ServiceImpl.class);
        intent.setFlags(intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra("from", "1");
        final int result=1;
        // androidContext.startActivity(intent);
        androidContext.startActivityForResult(intent, result);

The startActivity method (commented out) is found fine when used - the
one below it gives:

[ERROR] snapPic2Servlet.java:[89,22] cannot find symbol
symbol  : method startActivityForResult(android.content.Intent,int)
location: class android.content.Context

It has to be something stupid I can't see right now ...

 Where are you getting androidContext from?
