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
}
