AndroidX86模拟器Genymotion的一些使用和另一款Andy模拟器

命令行启动虚拟机

当我们下载安装好，可以通过命令行运行指定名字模拟器

Since Genymotion 2.5.0
gmtool admin create "Google Nexus 5 - 4.4.4 - API 19 - 1080x1920" myNexus
gmtool admin start myNexus

当使用genymotion的控制台shell时，一些命令在免费版本不可用，同样的界面上按钮也不可用。

其实，官方文档就有：https://www.genymotion.com/#!/support?chapter=start-virtual-devices-command-prompt

另外可以参考：How to start Genymotion device with shell command?

虽然早就看到这个问题的解决有一个是取消windows的hy设置，但是总以为分配ip和这个无关。最后不得不关掉这个设置重启机器，确实可行，机器为win10。

Interacting with virtual devices

To modify sensor statuses and values of a virtual device, use the commands listed below:

• devices list
  Lists available virtual devices and provides details such as current status, IP address and name.
• devices refresh
  Refreshes the virtual device list.
• devices select
  Selects a virtual device. Add the ID of the virtual device you wish to select (as displayed in the device list).
• devices ping
  Sends a ping message to check that the virtual device is responding.

取得系统时间

要得到目前的时间，这个倒是很容易，就是 System.currentTimeMillis()。不过要注意的是，这个函式传回的是 UTC (GMT) 这个时区的时间，像台湾所在的时区是 UTC+8，你得将这个函式所传回的值再加 8 个小时，才是你要的答案。实际上，当然不用自己加，你可以借用 Calendar 这个类别来帮你。

更改系统时间

要更改系统的时间，这可就难倒我了。在 m5 SDK 上，用 SystemClock.setCurrentTimeMillis()，虽然会有警告讯息，不过系统时间还是会被更改。到了 v0.9 SDK，这招就没效了。扫过 Android 的原始程式，他们的确是用这个函式在更改系统时间。可是在我的程式里，不管我加了那些 permission，都是给我个 Permission denied 错误。最好，只好在 这里发文问了这个问题，有个应该是 Google 的工程师，给了下面这个答案。

User apps cannot set the time. Only the system processes can. This is for security, but also because it won't have much effect--the time is reset from the radio via network time.

看了，要在 application 这一层更改系统时间，应该是没解了。如果有人知道其他答案的，帮忙解答一下。

取得与更改系统时区

用 TimeZone.getDefault() 就可以取得当前的时区，如果你没有特别设定的话，那你取到的，都是 GMT 这个时区。看起来，至少在 Windows 平台上， Android Emulator 还是不会正确决定当前的时区。目前我知道的唯一方法就是，在启动 Emulator 的参数上，加上 -timezone "Asia/Taipei"。透过启动 Emulator 的参数可以更改时区，那可以透过 API 来更改系统时区吗？我试过 TimeZone.setDefault(TimeZone.getTimeZone("Asia/Taipei"))，也用过 System.setProperty("user.timezone", "Asia/Taipei")，没一个有效。所以看起来，也暂时无解。有谁知道如何透过 API 更改系统时区？

设置系统的时区配置

cat /data/property/persist.sys.timezone //查看当前时区配置文件
setprop persist.sys.timezone GMT        //修改属性 
2、开始设置修改当前系统时间

date -s "yyyymmdd.[[[hh]mm]ss]"  或System/bin/date -s "yyyymmdd.[[[hh]mm]ss]"

3、查看是否生效

date

二、用代码实现修改android 系统时间的方法

public void testDate(){
try {
Process process = Runtime.getRuntime().exec("su");
String datetime="20131023.112800"; //测试的设置的时间【时间格式 yyyyMMdd.HHmmss】
DataOutputStream os = new DataOutputStream(process.getOutputStream());
os.writeBytes("setprop persist.sys.timezone GMT\n");
os.writeBytes("/system/bin/date -s "+datetime+"\n");
os.writeBytes("clock -w\n");
os.writeBytes("exit\n");
os.flush();
} catch (IOException e) {
e.printStackTrace();
}
}

android默认系统日期、时间、时区更改

做android平台，经常会遇到产品需要更改系统默认时区日期时间的问题。android更改时区相对比较容易实现，网上也有很多资料，直接设置一个属性即可，例如设置上海东八区，persist.sys.timezone=Asia/Shanghai。但是如何实现更改默认系统时间呢？

在android中，Linux内核中、rtc时钟，默认的起始日期都是1970年1月1日，那么如何把默认日期指到2012-01-01呢？笔者在实践中发现，在RTC驱动中可以很容易实现。在RTC驱动加载的时候，一般都有个probe函数需要先执行，因此在probe函数里下手最直接有效。RTC从1970-01-01开始，那当然很容易把默认值设置到2012-01-01，所需要设置的seconds也就是从1970-01-01所差的秒数，以秒为单位。因此，一旦读出来的RTC值小于我们预想的值比如2012-01-01（1325402913）小，我们就把它设置到这个时间点。

[cpp] view plaincopy

1.  seconds = rtc_read_time();

2.  printk("init PMU/RTC time to  %ld \n", seconds);

3.

4.  if(seconds <= 1325402913) {

5.      seconds = 1325402913;/*2012-01-01*/

6.      ret = rtc_set_time(seconds);

7.      RTC_DBG("Init Set time: %ld, ret =0x%x\n", seconds, ret);

8.  }

笔者通过结果显示，在android平台上是可行的。要设置到哪天几点几分，只要算好具体1970-01-01 00：00差的秒数即可，简单明了。这样客户、用户使用起来更方便一些。
