Android Debug Bridge（Android 调试桥） 针对移动端 Android 的测试， adb 命令是很重要的一个点，必须将常用的 adb 命令熟记于心， 将会为 Android 测试带来很大的方便，其中很多命令将会用于自动化测试的脚本当中。 adb 是一个 C/S 架构的命令行工具，用于通过电脑端与模拟器或者真实设备交互。在某些特殊的情况下进入不了系统，adb就派上用场了，主要由 3 部分组成： · 运行在 PC 端的 Client : 可以通过它对 Android 应用进行安装、卸载及调试 · 运行在 PC 端的 Service : 其管理客户端到 Android 设备上 adb 后台进程的连接 · 运行在 Android 设备上的 adb 后台进程 adb 服务启动后，Windows 可以在任务管理器中找到 adb.exe 这个进程 通过adb操作android设备 连接上数据线，然后把手机开发者模式打开，打开usb调试。 在配好环境变量的前提下，在命令窗口当中输入 adb help 或者直接输入 adb ，将会列出所有的选项说明及子命令。 在开发或者测试的过程中，我们可以通过 adb 来管理多台设备，其一般的格式为： adb [-e | -d | -s <设备序列号>] <子命令> adb devices 获取设备列表及设备状态 adb get-state

由 ぐ巨炮叔叔 提交于 2019-12-10 11:43:49
问题 I'm using logcat to log messages in my Android application, and I'd like to be able to access these messages and show them in a TextView in a DialogFragment. The list of messages is very inconsistent and changes each time I open and close the dialog. It shows the full history once, and then the next time it erases, and sometimes it shows some more messages. Is there anything that I can do to show all the messages (for the run) each time I open the dialog? Am I running the process at the wrong
