安卓java怎么修改系统时间,Java环境下Android系统时间修改方法详解

亲爱的安卓用户们，你是否曾想过，在安卓手机上，自己动手修改系统时间呢？是不是觉得这只是一个遥不可及的梦想？别急，今天我就要手把手教你，如何用Java在安卓设备上轻松修改系统时间，让你的手机时间随心所欲！

一、获取权限，开启冒险之旅

在开始修改系统时间之前，我们首先要做的是获取相应的权限。这就像是要去探险，必须先拿到地图和指南针。在安卓系统中，修改系统时间需要获得ROOT权限，因为这是一个涉及到系统安全的操作。

获取ROOT权限的方法有很多，这里我推荐使用“Magisk”这个工具。它可以帮助我们轻松地获取ROOT权限，而且操作简单，安全性高。

二、Java代码，掌控时间

获取了ROOT权限之后，我们就可以开始编写Java代码来修改系统时间了。这里，我为你准备了一段示例代码，让你轻松上手：

```java

import android.os.Process;

import java.io.DataOutputStream;

public class TimeChanger {

public static void main(String[] args) {

try {

// 获取root权限

Process process = Runtime.getRuntime().exec(\su\);

DataOutputStream outputStream = new DataOutputStream(process.getOutputStream());

// 设置新的系统时间
