startActivityForResult problems

 Hello All

I've use startActivityForResult as it described in many examples but
it return 0 result code after start new Activity.

In main Activity I use such code for sub activity invocation

                Intent iShowVideo = new Intent(EventHandling.this, 
ShowVideo.class);
                startActivityForResult(iShowVideo, 
this.REQUEST_CODE_SHOW_VIDEO);

And such code for getting results.

        @Override
        protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
                // TODO Auto-generated method stub
                //super.onActivityResult(requestCode, resultCode, data);
                if(requestCode == REQUEST_CODE_SHOW_VIDEO){
                        if(resultCode == RESULT_CANCELED){
                                Toast toast = Toast.makeText(this, 
"onActivityResultCancel: " +
String.valueOf(resultCode), Toast.LENGTH_LONG);
                                toast.show();
                        }else{
                                Toast toast = Toast.makeText(this, 
"onActivityResult: " +
String.valueOf(resultCode), Toast.LENGTH_LONG);
                                toast.show();
                        }
                }
        }

Here is a part code from ShowVideo activity
        @Override
        protected void onCreate(Bundle savedInstanceState) {
                // TODO Auto-generated method stub
                super.onCreate(savedInstanceState);

                setContentView(R.layout.showvideo);
                //showDialog(DIALOG_YES_NO_MESSAGE);

        Button button = (Button)findViewById(R.id.btnOK);
        button.setOnClickListener(mOkListener);
        button = (Button)findViewById(R.id.btnCancel);
        button.setOnClickListener(mCancelListener);

        //setResult(RESULT_OK, (new Intent()).setAction("Test!"));
        }

    private OnClickListener mOkListener = new OnClickListener()
    {
        public void onClick(View v)
        {
            // To send a result, simply call setResult() before your
            // activity is finished.
            setResult(RESULT_OK, (new Intent()).setAction("Corky!"));
            finish();
        }
    };

This code should work according many examples. And it should return
RESULT_OK after btnOK clicked but after I click this button it only
closes ShowVideo  Activity.

Please help.

startActivityForResult problems

 Not sure if this is your problem, but I do notice you commented out
the super.onActivityResult function in your onActivityResult function.
I don't know all of what the parent method for that function does, but
it's pretty good practice to always call the super method first when
you override a method. It could be doing some setup for you.

I could be way off and that's not what's causing your problem, but
it's a good idea to do it anyway, except for in methods where you know
you shouldn't, like the method for an option item being selected.

 I found the problem.
It's a singleInstance application launchMode.

What resolution is your screen?  What density is it reporting?  What is the
configuration of the emulator in which it is working?  In what way aren't
they fitting?

You probably need to describe your problem a little more for people to be
able to help you?

2. If the bluetooth is build as module not build in, where is better to insmod it

Hi Pavan and Nick,

Thanks for the suggestions! Seems insmod in bluetooth.c is not a good
idea, it do increments the rfkill. I'll put it into init.rc first,
maybe build in finially.

Thanks again!
