Android 检测程序异常崩溃，重启应用

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.ArrayListimport 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    list = new ArrayList();    @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 java.lang.Thread.UncaughtExceptionHandler;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";    MyApplication                    application;    public CashHandler(MyApplication myApplication){        // // 获取系统默认的UncaughtException处理器        mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();        this.application = myApplication;    }    @Override    public void uncaughtException(Thread thread, Throwable ex) {        // TODO Auto-generated method stub        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) {                // TODO Auto-generated catch block                Log.e(TAG, "error ;", e);            }            Intent intent = new Intent(application.getApplicationContext(), MainActivity.class);            PendingIntent restartIntent = PendingIntent.getActivity(application.getApplicationContext(), 0, intent, Intent.FLAG_ACTIVITY_NEW_TASK);            // 退出程序            AlarmManager mgr = (AlarmManager) application.getSystemService(Context.ALARM_SERVICE);            mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 1000, restartIntent); // 1秒后重启            application.finishActivity();        }    }    /**     * 自定义错误处理,收集错误信息 发送错误报告等操作均在此完成.     *      * @param ex     * @return true:如果处理了该异常信息;否则返回false.     */    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();                Looper.loop();            };        }.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);    }
