【MAC】android studio连接真机调试

前提

1. 配置好了Android开发环境，能在终端中使用adb命令
2. sdk Manage中的SDK Tools下已经勾选Google Usb Driver了
3. 手机连接上Mac了

问题来了： 手机连接上电脑是有反应的，而且重启adb后adb devices是能看到机子连接上（反正我的是能看到），然后点击运行项目，报错了，说找不到设备（这个时候adb devices后机子又不见了）。

解决方法

步骤：

1. 下载Android File Transfer
   
2. 获取电脑上的USB连接信息,找到连接上的手机的连接信息

3. 把手机的Vendor ID: 0x2717写入~/.android/adb_usb.ini文件中

MacBook-Pro ~ % vi ~/.android/adb_usb.ini

MacBook-Pro ~ % cat ~/.android/adb_usb.ini
0x2717

4. 重新启动adb

MacBook-Pro ~ % adb kill-server
MacBook-Pro ~ % adb start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully

5. 查看是否连接上了

MacBook-Pro ~ % adb devices
