Android : Android Java Application is freezing with No Error message being sent back

for some Reason my Android Java App is freezing when i press a certain button. However the app doesnt seem to be crashing since no error message is send back to Android Studio. It just freezes and after a while the app will restart.

Here is the Code that is executed on ButtonClick. I am aware that this is very confusing because i am using so many variables :/ i will try to put some declaration above the actualy Button Code.

ChronometerList = new Chronometer[]{Overtime1,Overtime2,Overtime3,Overtime4,Overtime5,Overtime6,Overtime7,Overtime8,Overtime9,Overtime10,Overtime11,Overtime12};
 //is an Array of Chronometers

    TimeList = new TextView[]{ TimeUntilTopic1Ends,TimeUntilTopic2Ends,TimeUntilTopic3Ends,TimeUntilTopic4Ends,TimeUntilTopic5Ends,TimeUntilTopic6Ends,TimeUntilTopic7Ends,TimeUntilTopic8Ends,TimeUntilTopic9Ends,TimeUntilTopic10Ends,TimeUntilTopic11Ends,TimeUntilTopic12Ends}; 
    // Array of Textviews, that show us the Time Left, i need so many since i build a table out of lines and every line needs a timer

    TopicTimer = new MyCounter[]{TopicTimer1,TopicTimer2,TopicTimer3,TopicTimer4,TopicTimer5,TopicTimer6,TopicTimer7,TopicTimer8,TopicTimer9,TopicTimer10,TopicTimer11,TopicTimer12};

// MyCounter is extended by Countdowntimer -> Simple Class //All the Timer are being build fine with no error

Here is the Code. Hella confusing but i hope you can help anyways :D

  NextTopic.setOnClickListener(new OnClickListener() {

       @Override
       public void onClick(View v) {
        // TODO For some Reason this freezes the Whole Program
           if(TimeList[row-1].getText().toString() == "Done")
           {
               ChronometerList[row-1].stop();
               long ElapsedTimeInMillis = SystemClock.elapsedRealtime() - ChronometerList[row-1].getBase();
               int RowUsed = 0;

                  double SubtractionTime = ElapsedTime / RowUsed;

                  while (RowUsed >= n) {
                      TimeList[row + n].setText(String.valueOf(Double.parseDouble(TimeList[row + n].getText().toString()) - SubtractionTime));

               }
            // have to split up the text in there cause there are **m **s in it and not just the number
            String TimeOutput = TimeList[row - 1].getText().toString();
            String[] TimePartSeconds = TimeOutput.split("m ");
            String Minutes = TimePartSeconds[0];
            String SecondsLetters = TimePartSeconds[1];
            String[] GetSeconds = SecondsLetters.split("s");
               String seconds = GetSeconds[0];


            int SecondsLeft = (Integer.valueOf(Minutes)*60) +(Integer.valueOf(seconds));
            long AdditionTimeSeconds = SecondsLeft/RowsLeft;

            TopicTimer[row-1].onFinish();


            while (RowsLeft>= n) {
                   TimeList[row + n].setText(String.valueOf(Double.parseDouble(TimeList[row - 1 + n].getText().toString()) + (AdditionTimeSeconds/60)));
                   n++;
               }
              row++;

       }
   });
