由 自作多情 提交于 2021-02-18 18:52:57
问题 I have an int "flag" variable , which will have two possible int values , 0 & 1. Main theme of the app here is : Ask user yes or no? If user selects YES, assign int=1. else if Selects No, assign int=0; I am achieving this using: public static int flag; @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.flag0: flag=0; System.err.println("Flag : " + flag); break; case R.id.flag1: flag=1; System.err.println("Flag : " + flag); break; default:

Appium环境搭建 谷歌驱动和对照：注意：64位向下兼容，直接下载32位的就可以啦，亲测可用。 https://blog.csdn.net/allthewayforward/article/details/81736418 本文主要讲述 Appium 环境的搭建，虽然网上有很多 Appium 的搭建教导教程，但大数描述不够祥细而导致环境搭建失败。本人经过多次实验，终找到了搭建成功的方法，分享给大家进行参考 工具 /原料 夜神模拟器连接手机 {SDK目录下的adb.exe文件，复制到夜神模拟器的目录下，复制过去之后改名为nox_adb.exe} 3.然后命令行窗口中输入adb connect 127.0.0.1:62001即可以连接到adb .启动要查看的程序， usp连接手机后---手机打开usp调试命令行输入： 使用adb shell dumpsys window | findstr mCurrentFocus 命令查看当前运行的包名和Activity更清晰。 Java（JDK），AndroidSDK（SDK），Android模拟器、Appium服务端、Python 库 方法 /步骤 1 安装配置 JDK 环境：安装 JDK 过程简单，不再累述；下面进行 JDK 的配置，参数如下： JAVA_HOME （你的 JDK 安装位置，如： C:\Program Files\Java

由 时光毁灭记忆、已成空白 提交于 2021-02-18 18:19:08
问题 I can't figure out how to access the led light on my android with python or kivy, I have tried installing python-for-android to be able to import the android module into my code but it's not the module can't be found.

Can someone please point me in the right direction? 回答1: Yes, you can write this app in Kivy from the desktop,

Firebase connection detection does not work after 60 seconds

由 北慕城南 提交于 2021-02-18 18:15:54
问题 As explained in some answers: On Android, Firebase automatically manages connection state to reduce bandwidth and battery usage. When a client has no active listeners, no pending write or onDisconnect operations, and is not explicitly disconnected by the goOffline method, Firebase closes the connection after 60 seconds of inactivity. The problem is that after 60s, even after I go to an activity with a complete new reference, event listener, etc.. It still says it is disconnect, when in fact,

由 不想你离开。 提交于 2021-02-18 18:12:21
问题 How can I successfully activate the demo mode for the status bar in android programmatically?

The adb commands are working without an issue. Thank you very much! 回答1: I found out that it's not possible for not system apps to do this

FTPClient.storeFile() uploads slowly and then doesn't work

问题 Android n00b trying to figure out file server upload. I'm having a lot of trouble trying to upload a file to my FTP server in Android using the storeFile method in FTPClient , testing on a Galaxy Nexus. Two problems. First, it runs very, VERY slowly - like a minute or more for a file of a few bytes before the code moves on (so that my display often goes to sleep before it finishes running). Second, no file arrives on the server when it's done. But the code does continue running and I don't
