Toast.show than move to another Activity -> fatal exception: no dialog with id X was ever shown via Activity#showDialog

W/ActivityManager(  238): Activity pause timeout for HistoryRecord{2b54bd38 com.proapps.eng.android.client/.MainScreenActivity}

This exception is thrown after Toast.show() and right after that,start a new activity (the main one) instead of finish() the current.

final Handler handler = new Handler() {
    public void handleMessage(Message msg) {
        // Get the current value of the variable total from the message data
        // and update the progress bar.
        int total = msg.getData().getInt("total");
        progDialog.setProgress(total);
        if (total <= 0){
            dismissDialog(typeBar);
            progThread.setState(ProgressThread.DONE);
            mail_sent_popup.show(); // mail sent popup
            startActivity(new Intent(cntx,MainScreenActivity.class));      
        // start the main instead of finishing this one.
        }
    }
}; 

When passing to the new activity it 'forgets' that the dialog was introduced in previous activity. What should I do?

BTW its not always throws ,only from time to time. Thanx!!!

EDIT : Some more code (of the dialog thread)

private class ProgressThread extends Thread {

    // Class constants defining state of the thread
    final static int DONE = 0;
    final static int RUNNING = 1;

    Handler mHandler;
    int mState;
    int total;


    EditText name_text = (EditText)findViewById(R.id.editText1);
    EditText phone_text = (EditText)findViewById(R.id.editText2);
    EditText free_text = (EditText)findViewById(R.id.editText3);

    // Constructor with an argument that specifies Handler on main thread
    // to which messages will be sent by this thread.

    ProgressThread(Handler h) {
        mHandler = h;
    }

    // Override the run() method that will be invoked automatically when 
    // the Thread starts.  Do the work required to update the progress bar on this
    // thread but send a message to the Handler on the main UI thread to actually
    // change the visual representation of the progress. In this example we count
    // the index total down to zero, so the horizontal progress bar will start full and
    // count down.

    @Override
    public void run() {
        mState = RUNNING;   
        total = maxBarValue;
        while (mState == RUNNING) {

                // LONG JOB HERE

                }

            Message msg = mHandler.obtainMessage();
            Bundle b = new Bundle();
            b.putInt("total", 0);
            msg.setData(b);
            mHandler.sendMessage(msg);

        }
    }

    // Set current state of thread (use state=ProgressThread.DONE to stop thread)
    public void setState(int state) {
        mState = state;
    }
}

I guess dismissDialog(typeBar); is the wrong method to stop this thread. I don't know where I should put state=ProgressThread.DONE in the code

EDIT2:

I've added the code that declares the dialog and parts of onCreate of the Activity:

public void onCreate(Bundle savedInstanceState) {
    ...
    ...
    showDialog(2);
    ...
}


    @Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,mDay);
    case TIME_DIALOG_ID:
        return new TimePickerDialog(this, mTimeSetListener, mHour, mMinute,false);
    case 2:
        progDialog = new ProgressDialog(this);
        progDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        progDialog.setMessage("Sending...");
        progThread = new ProgressThread(handler);
        progThread.start();
        return progDialog;
    }
    return null;
}

Answer 1

this is how i've solved this issue:

    final Handler handler = new Handler() {
    public void handleMessage(Message msg) {
        // Get the current value of the variable total from the message data
        // and update the progress bar.
        int total = msg.getData().getInt("total");
        progDialog.setProgress(total);
        if (total <= 0){
            progThread.setState(ProgressThread.DONE);
//          dismissDialog(typeBar);     // PROBLEMATIC
            mail_sent_popup.show(); // mail sent popup
            startActivity(new Intent(cntx,MainScreenActivity.class));
// start the main instead of finishing this one.
        }
    }
};

Just commented the manual dismissDialog and let the thread die with progThread.setState(ProgressThread.DONE); hope this helps somebody.

Generally, a Dialog is owned by a single Activity. You can't show a dialog in ActivityA and then dismiss it in ActivityB.
