在Android中编程生命游戏，在尝试创建新一代时崩溃

Question

我正在尝试将Conway的生命游戏编程为Android应用程序。我创建了我可以绘制的初始网格，并设计了一个引擎。但是，当我尝试使用我的初始网格作为输入并运行引擎时，应用程序崩溃了。引擎的代码如下，如果有人能指出我如何创建工作引擎的话，我将不胜感激。

我看到的主要错误是“线程退出未捕获的异常”

LifeEngine.java

public class LifeEngine {

    private Context context; 
    private NeighborCheck checker; 
    private MyGridView myGridView; 
    private int height = this.myGridView.getMyHeight();
    private int width = this.myGridView.getMyWidth();

    public LifeEngine(Context context) {
        this.context = context;
    }

    public char[][] generateNextGeneration(char[][] world) {

        //char[][] currentGeneration = world;
        int neighbors; 
        char[][] nextGeneration = new char[this.myGridView.getMyHeight()][this.myGridView.getMyWidth()];

        for (int c = 0; c < height/UpdateGridActivity.cell_size; c++) {
            for (int r = 0; r < width/UpdateGridActivity.cell_size; r++) {
                if(world[c][r] != 0) //handles live cells 
                {
                    neighbors = checker.check(world,r, c);
                    if (neighbors !=3 && neighbors !=2) 
                        nextGeneration[c][r] = 0; 
                    else
                        nextGeneration[c][r] = '*'; 
                }
                else //handles dead cells
                {
                    neighbors = checker.check(world,r, c);
                    if(neighbors == 3)
                        nextGeneration[c][r] = '*';
                    else
                        nextGeneration[c][r] = 0;
                }
