app崩溃后捕获异常或自动重启

        import java.lang.Thread.UncaughtExceptionHandler;        import android.app.Application;        import android.content.Intent;        public class AppContext extends Application {            protected static AppContext instance;            public void onCreate() {                super.onCreate();                instance = this;                Thread.setDefaultUncaughtExceptionHandler(restartHandler); // 程序崩溃时触发线程  以下用来捕获程序崩溃异常                }            // 创建服务用于捕获崩溃异常                private UncaughtExceptionHandler restartHandler = new UncaughtExceptionHandler() {                public void uncaughtException(Thread thread, Throwable ex) {                    restartApp();//发生崩溃异常时,重启应用                    }            };            public void restartApp() {                Intent intent = new Intent(instance,                        LoginActivity.class);                PendingIntent restartIntent = PendingIntent.getActivity(                        this.getApplicationContext(), 0, intent,                        Intent.FLAG_ACTIVITY_NEW_TASK);                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                instance.startActivity(intent);                android.os.Process.killProcess(android.os.Process.myPid());  //结束进程之前可以把你程序的注销或者退出代码放在这段代码之前            }        }
