感觉ActivityStack没啥可以讲的主要目的就是将activity存入一个自己定义的栈中再根据自己的需要处理activity中的信息
代码如下

public class ActivityStack {    private final static String TAG = "ActivityHolder";    private List<FragmentActivity> activityList = new ArrayList<FragmentActivity>();    ;    private static ActivityStack instance;    private ActivityStack() {    }    public static synchronized ActivityStack getInstance() {        if (instance == null) {            instance = new ActivityStack();        }        return instance;    }    /**     * add the activity in to a list end     *     * @param activity     */    public void addActivity(FragmentActivity activity) {        try {            if (activity != null && activityList != null) {                int size = activityList.size();                if (checkActivityIsVasivle(activity)) {                    removeActivity(activity);                    activityList.add(activityList.size(), activity);                } else {                    activityList.add(activity);                }                size = activityList.size();                for (int i = 0; i < size; i++) {                    LogUtils.i("addActivity ==[" + i + "]" + " " + activityList.get(i));                }            }        } catch (Exception e) {            // TODO: handle exception        }    }    /**     * 获取当前Activity（堆栈中最后一个压入的）     */    public Activity currentActivity() {        Activity activity = activityList.get(0);        return activity;    }    /**     * 结束当前Activity（堆栈中最后一个压入的）     */    public void finishCurActivity() {        Activity activity = currentActivity();        activityList.remove(0);        activity.finish();    }    /**     * finish all the activity in the list.     * <p/>     * <p/>     * the activity calling this method hold the context     */    public void finishAllActivity() {        if (activityList != null) {            int size = activityList.size();            for (int i = size - 1; i >= 0; i--) {                FragmentActivity activity = activityList.get(i);                if (activity != null) {                    activity.finish();                }                LogUtils.i("finishAllActivity ==[" + i + "]" + " " + activity);                activityList.remove(activity);                // activityList.clear();            }        }    }    /**     * finish all the activity in the list.     * <p/>     * <p/>     * the activity calling this method hold the context     */    public void finishOtherActivity(FragmentActivity activityCurrent) {        if (activityList != null) {            int size = activityList.size();            for (int i = size - 1; i >= 0; i--) {                FragmentActivity activity = activityList.get(i);                if (activity != null && activity != activityCurrent) {                    if (activity != null) {                        activity.finish();                    }                    LogUtils.i("finishAllActivity ==[" + i + "]" + " " + activity);                    activityList.remove(activity);                }            }        }    }    /**     * remove the finished activity in the list.     *     * @param activity the activity is removed from activityList     */    public void removeActivity(FragmentActivity activity) {        try {            if (activityList != null) {                activityList.remove(activity);                LogUtils.i("removeActivity==" + " " + activity + "activityList.size===" + activityList.size());            }        } catch (Exception e) {            LogUtils.e("removeActivity" + e.getMessage());        }    }    public void pop(Class<? extends FragmentActivity> activity) {        for (Activity a : activityList) {            LogUtils.i(a.getClass().getName() + "--->" + activity.getName());            if (a.getClass().getName().equals(activity.getName())) {                if (!a.isFinishing()) {                    a.finish();                }            }        }        activityList.remove(activity);    }    public boolean checkActivityIsVasivle(FragmentActivity activity) {        LogUtils.i(" " + activityList.contains(activity));        return activityList.contains(activity);    }    /**     * <p>     * 功能 干掉除home外的所有activity     * </p>     *     * @author sss 时间 2013年12月11日 上午5:38:59     */    public void finishWorkActivity() {        Activity act = null;        for (int index = 0; index < activityList.size(); index++) {            act = activityList.remove(index);            if (act == null) {                continue;            }            // if(act.getClass()==HomeActivity.class){            // continue;            // }            act.finish();        }    }    public static boolean isTopActivity(FragmentActivity activity) {        boolean isTop = false;        ActivityManager am = (ActivityManager) activity.getSystemService(Context.ACTIVITY_SERVICE);        ComponentName cn = am.getRunningTasks(1).get(0).topActivity;        if (cn.getClassName().contains(activity.getClass().getSimpleName())) {            isTop = true;        }        return isTop;    }}

与之关联的还有一个处理app异常的类代码如下

public class AppException extends Exception implements UncaughtExceptionHandler {    private static final long serialVersionUID = -6262909398048670705L;    private String message;    private Thread.UncaughtExceptionHandler mDefaultHandler;    private AppException() {        super();        this.mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();    }    public AppException(String message, Exception excp) {        super(message, excp);        this.mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();    }    public String getMessage() {        return message;    }    public void setMessage(String message) {        this.message = message;    }    /**     * 获取APP异常崩溃处理对象     *     * @return     */    public static AppException getAppExceptionHandler() {        return new AppException();    }    @Override    public void uncaughtException(Thread thread, Throwable ex) {        if (!handleException(ex) && mDefaultHandler != null) {            Log.e("=uncaughtException=","uncaughtException");            if (InnoFarmApplication.getAppContext()!=null){               TCAgent.onError(InnoFarmApplication.getAppContext(), ex);            }            mDefaultHandler.uncaughtException(thread, ex);        }    }    /**     * 自定义异常处理     *     * @param ex     * @return true:处理了该异常信息;否则返回false     */    private boolean handleException(Throwable ex) {        if (ex == null) {            return false;        }        final String errLog = ex.toString();        final Activity activity =  ActivityStack.getInstance().currentActivity();        if (activity == null) {            return false;        }        new Thread() {            @Override            public void run() {                Looper.prepare();                new AlertDialog.Builder(activity).setTitle("提示")                        .setCancelable(false).setMessage(errLog)                        .setNeutralButton("确定", new OnClickListener() {                            @Override                            public void onClick(DialogInterface dialog,                                                int which) {                                AppManager.getAppManager().finishAllActivity();                                android.os.Process.killProcess(android.os.Process.myPid());                                System.exit(1);                            }                        }).create().show();                Looper.loop();            }        }.start();        return true;    }}

这样的话我们就能判断异常位置我们的BaseActivity是这样处理的

public abstract class BaseActivity extends FragmentActivity {    //  管理所有打开的activity    //  static  和对象没有关系  和类有关系    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);       Thread.setDefaultUncaughtExceptionHandler(AppException.getAppExceptionHandler());        init();        initView();        ActivityStack.getInstance().addActivity(this);    }    @Override    protected void onResume() {        super.onResume();    }    @Override    protected void onPause() {        super.onPause();    }    @Override    protected void onDestroy() {        super.onDestroy();        ActivityStack.getInstance().removeActivity(this);    }    /**     * 初始化     */    protected abstract void init();    /**     * 初始化view界面     */    protected abstract  void initView() ;}
