Question

我的应用程序有一个非常奇怪的问题！

我一直在bluestacks上编程，一切都很好 - 没有崩溃或者什么都没有。当我将apk移动到我的手机时它也工作正常直到我关闭应用程序 - 这导致了崩溃，我不知道如何获取。

这让我怀疑我的问题与我正在使用的SurfaceView有关，但我不知道导致崩溃的问题可能是什么。

这里是onCreate：

GameView g;
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         g=new GameView(this);
        setContentView(g);
    }

以下是我创建surfaceview的方法：

gameLoopThread = new GameLoopThread(this);
        this.requestFocus();
        this.setFocusableInTouchMode(true);
        holder = getHolder();
        holder.addCallback(new SurfaceHolder.Callback() {

            @Override
            public void surfaceDestroyed(SurfaceHolder holder) {
                boolean retry = true;
                gameLoopThread.setRunning(false);
                while (retry) {
                    try {
                        gameLoopThread.join();
                        retry = false;
                    } catch (InterruptedException e) {
                    }
                }
            }

            @Override
            public void surfaceCreated(SurfaceHolder holder) {
                gameLoopThread.setRunning(true);
                gameLoopThread.start();
            }

            @Override
            public void surfaceChanged(SurfaceHolder holder, int format,
                    int width, int height) {
            }
        });
    }

，这是主题：

import android.annotation.SuppressLint;
import android.graphics.Canvas;

public class GameLoopThread extends Thread {
       static final long FPS = 60;
       private GameView view;
       private boolean running = false;

       public GameLoopThread(GameView view) {
             this.view = view;
       }

       public void setRunning(boolean run) {
             running = run;
       }

       @SuppressLint("WrongCall") @Override
       public void run() {
             long ticksPS = 1000 / FPS;
             long startTime;
             long sleepTime;
             while (running) {
                    Canvas c = null;
                    startTime = System.currentTimeMillis();
                    try {
                           c = view.getHolder().lockCanvas();
                           synchronized (view.getHolder()) {
                                  view.onDraw(c);
                           }
                    } finally {
                           if (c != null) {
                                  view.getHolder().unlockCanvasAndPost(c);
                           }
                    }
                    sleepTime = ticksPS-(System.currentTimeMillis() - startTime);
                    try {
                           //if (sleepTime > 0)
                               //   sleep(sleepTime);
                          // else
                                  //sleep(10);
                    } catch (Exception e) {}
             }
       }
}

我没有触及ondestroy或onstop，所以问题必须出在我怀疑的surfaceview中。

编辑2 我找到了手机的logcat，这里是崩溃： enter image description here

Answer 1

根据logcat输出的屏幕抓取，您从java.lang.Thread.stop()获得UnsupportedOperationException。这是所有Android版本的行为，因为该调用已被弃用，除了抛出异常之外什么都不做。

从您的代码（Sp.game.spiceinspace.MainActivity.onStop，MainActivity.java第26行）调用它。你需要停止这样做，并以其他方式结束线程。

应用程序可能也会在模拟器上崩溃，但出于某种原因，崩溃并未引起您的注意。

应用程序关闭后崩溃
