Question

I have following code:

    mQuestions=DictionaryDbWrapper.getInstance().getQuestionsSequence(
            this.getIntent().getStringExtra(ApplicationUtilities.TEST_CATEGORY_PARAMETER), 50);
    mQuestionsCount=mQuestions.size();
    Log.e("count", String.valueOf(mQuestionsCount));
    if (mQuestionsCount==0) {
        Log.e("1", "111");
        Toast.makeText(this, "В данной категории нет слов", Toast.LENGTH_LONG).show();
        this.finish();
    }

    makeQuestion();

mQuestions is empty ArrayList, and I see that count equals 0 on Log always. Also I see 1/111 record on my Log always too. But my activity doesn’t do a finish method!

makeQuestion is method that needn’t work with empty mQuestion (it throw Exception). But If I make a comment for makeQuestion then finish method works well! Method for this code works on main thread (it is executed from onCreate() method).

Please, suggest where I am going wrong.

Thanks in advance.

Answer 1

The finish() function is non-blocking, this means that the execution will continue while the activity is finishing in background.

To solve your problem, add a return statement after the finish() call.
