Application类设置
监听到错误,退出程序(注意当发生错误时,发送广播,跳转Intent等方式都是无效的)

package com.siyehua.testanimation;
import java.util.LinkedList;
import java.util.List;
import android.app.Activity;
import android.app.Application;
import android.content.Intent;
import android.util.Log;
import com.siyehua.testanimation.CrashHandler.ErrorListener;
public class SiApplication extends Application {
    private static SiApplication instance;
    private List mList = new LinkedList();
    public void exit() {
        try {
            for (Activity activity : mList) {
                if (activity != null)
                    activity.finish();
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            System.exit(0);
        }
    }
    // add Activity
    public void addActivity(Activity activity) {
        mList.add(activity);
    }
    public synchronized static SiApplication getInstance() {
        return instance;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
        CrashHandler a = CrashHandler.getInstance();
        a.init(this);
        a.setOnErrorListener(new ErrorListener() {
            @Override
            public void error() {
                Log.e("接收到错误消息", "");
                sendBroadcast(new Intent("siyehua"));//此句无效,无法发送广播,或启动服务
            }
        });
    }
}

最后一步:在BaseActivity中Activity加入到集合中

SiApplication.getInstance().addActivity(this);
