i made the tictactoe game using dynamic layout and applied with logic of 3*3 matrix,if i enter 3 in input so it will make 3*3 matrix, if i will enter 4 in input so it will create 4*4 matrix,i have already make the logic for 3*3 matrix so now i want to make logic for tictactoe which can be applicable for all input.

there is no error for 3*3 matrix,but i want to make dynamic logic which is applicable for all input.

Above is the MainActivity in AndroidStudio. I got parcel size error first now I got On click error while trying to debug. I'm so lost. I assume the error is in the TicTacTocPLay class especially in the runnable and run method. But i still havent been able to pinpoint the error. So, in the main method there is a play button which should direct to the second activity which is the TicTacTocPlay class. In the emulator the app crashes when I press play.

I managed to retrieve the data from firebase, implementing an infinite scroll... is working right but when i scroll till end, is loading the same last values always..
Tried to change the .limitToLast to .startAt but there is no difference.

Also checked the log and is giving the result "data is over" but continues doing the same thing always. Any clue?

I'm building an application that makes piechart from database according to precise date interval. Unfortunately the achartengine's repaint function is not working when I'm stepping with the buttons.
When the Activity starts everything is fine the chart is okay but when i'm using the buttons then nothing happens.
I hope somebody can help me.
here is the code:
private GraphicalView chartView;
...
tabHost.addTab(tabHost.newTabSpec("").setIndicator("Grafikon")

.findViewById(R.id.summenutab3_periodtw);
if (chartView == null) {
LinearLayout layout = (LinearLayout) view.findViewById(R.id.chart);
intValChanger(intVal, 0);
layout.addView(chartView);
} else {
chartView.repaint();
}

I have not used Achart but this is a simple pie chart implementation. You can refer the demo and it might help.
In this demo after you update the values, you need to call invalidate() to redraw the pie chart.
