程序实时监测，程序异常   注意：Application 需在清单文件中注册

package com.catch.catchex;

import java.util.ArrayList

import com.catch.catchex.CashHandler ;
import android.app.Activity;
import android.app.Application;
import android.content.Context;

public class MyApplication extends Application {

    private static Context context;
    ArrayList<Activity>    list = new ArrayList<Activity>();

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    /**
     * context
     */
    public static Context getContext() {
        return context;
    }

    public void init() {
        // 设置该CashHandler为程序的默认处理器
        CashHandler unCeHandler = new CashHandler(this);
        Thread.setDefaultUncaughtExceptionHandler(unCeHandler);
    }

    /**
     * @param activity activity关闭时，删除Activity列表中的Activity对象
     */
    public void removeActivity(Activity activity) {
        list.remove(activity);
    }

    /**
     * @param activity 向列表中添加Activity对象
     */
    public void addActivity(Activity activity) {
        list.add(activity);
    }

    /**
     * @param activity 关闭Activity列表中的 所有Activity
     */
    public void finishActivity() {
        for (Activity activity : list) {
            if (null != activity) {
                activity.finish();
            }
        }
        // 杀死应用进程
        android.os.Process.killProcess(android.os.Process.myPid());
    }

}

异常处理器 CashHandler 

package com.catch.catchex;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Looper;
import android.util.Log;
import android.widget.Toast;

import com.catch.catchex.MainActivity;
import com.catch.catchex.MyApplication;

public class CashHandler implements UncaughtExceptionHandler {

    private UncaughtExceptionHandler mDefaultHandler;
    public final String              TAG = "CatchExcep";

        this.application = myApplication;
    }

    @Override

        if (!handlerException(ex) && mDefaultHandler != null) {
            // 若果用户没有处理则让系统默认的异常处理器来处理
            mDefaultHandler.uncaughtException(thread, ex);
        } else {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {

            application.finishActivity();
        }
    }

    /**

     */
    private boolean handlerException(Throwable ex) {
        // TODO Auto-generated method stub
        if (ex == null) {
            return false;
        }
        // 发个友好的提示，弹个土司
        new Thread() {

            public void run() {
                Looper.prepare();
                Toast.makeText(application.getApplicationContext(), "检测到程序异常，即将退出", Toast.LENGTH_SHORT).show();

            };
        }.start();
        return true;
    }

}

MainActivity 中初始化

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);                         
        setContentView(R.layout.activity_main);      
        CatchExcApplication(); // 检测程序异常
        initView(); // 初始化View
                    }

 /**
     * 检测程序异常，重启
     */
    public void CatchExcApplication() {
        // 添加程序异常检测
        MyApplication application = (MyApplication) getApplication();
        application.init();
        application.addActivity(this);
    }

清单文件配置 MyApplication

 <application
        android:name="com.catch.catchex.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher_camera"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.catch.catchex.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
