Hi,
I launch an application called DecisionTreeActivity by this code :
Intent i = new Intent(Intent.ACTION_MAIN);
ComponentName toLaunch;
toLaunch = new ComponentName("com.tests.decisionTree",
com.tests.decisionTree.DecisionTreeActivity");
i.addCategory(Intent.CATEGORY_LAUNCHER);
i.setComponent(toLaunch);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
this.startActivityForResult(i, 42);
Then, in DecisionTreeActivity, I send the result back with :
Intent i = new Intent();
i.putExtra("decision", outputToReturn);
setResult(RESULT_FIRST_USER, i);
this.finish();
Here is my onActivityResult(int requestCode, int resultCode, Intent
data) function. Everything is working fine when these activities are
in the same apk file but here I have to put them into two separate apk
files.
onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println(requestCode + " " + resultCode);
if(requestCode == 42) {
String s = (String) data.getStringExtra("decision");
System.out.println(">>>>>>>>>> Decision: " + s + "
<<<<<<<<<<<<<");
}
}
When onActivityResult is "called", I have those exceptions thrown :

I really don't understand what the problem is. What changes when I
associated these two activities with different apk file.
Note that the important line is :
10-03 15:41:32.321: ERROR/AndroidRuntime(1452):
java.lang.RuntimeException: Failure delivering result ResultInfo
{who=null, request=42, result=0, data=null} to activity
where we can read that the intent is null (that is really not
normal !!)
Could you help me ?
Thanks,
Regard,
D.
