终于用ADB连上平板了
可以看到设备管理器里， ADB Interface 设备装不上驱动。
1，百度到的内容，没有一个靠谱的。
2，google到内容了， 却因为看的不仔细，浪费了好多时间。。。（android自己的文章都是有问题的）
3，最近（2018/3/9）又重新安装了一下。 翻—墙单独下了 usb driver （上传到cnblogs了）,这样就不用下载整个sdk. 不过，安装次序没变，一点都不能偷懒。
google_adb_usb_driver_windows.zip
下面的才是正确的，注意红字！！！
Step 1: Download Android SDK: Android SDK download link
Scroll to the bottom of the page linked above, then click on “Download for other platforms”. From there, you can download the zip version as well as the exe installer. File names will be like:
- Zip Package for Windows: android-sdk_r21.0.1-windows.zip
- SDK Installer for Windows: installer_r21.0.1-windows.exe
Download the one of your choice.
Step 2: If you downloaded the zip package, extract it to a convenient location. If you downloaded .exe installer, install it on your PC.
For this guide, we extracted the zip file to D:\ drive. Upon extracting, it will create a directory named android-sdk-windows.
Step 3: Open the android-sdk-windows directory and run the SDK Manager.exe. It will fetch all the packages for you, wait till it’s done.
From here, you can install or delete the packages.
Step 4: Select following packages to install:
- Android SDK Platform-tools
- Google USB Driver
After selecting the packages and unchecking all other options, click “Install 2 packages…” button at bottom right.
Step 5: A window will appear asking for confirmation. Select “Accept All” option and click on “Install” button to continue.
The selected packages will now be downloaded and installed. Be patient. After it’s done, you will see the confirmation message in SDK Manager.
Step 6: Now connect your device to the computer. You will notice drivers getting installed, which will eventually fail. Don’t worry.
Step 7: Open Device Manager and locate your device under “Other devices”.
Step 8: Right click on your device and then click on “Update driver software”.
Step 9: Now click on “Browse my computer for driver software” option.
Step 10: In next screen, click on the option “Let me pick from a list of device drivers on my computer”.
Step 11: Now select “Show All Devices” option and click the next button.
Step 12: Now click on “Have Disk…” button. A window will pop up, click the browse button and browse to following location: D:\android-sdk-windows\extras\google\usb_driver and select android_winusb.inf file.
Note: If you installed / extracted the Android SDK to a different location, browse to that location instead of D:\.
Step 13: In next screen, select “Android Composite ADB Interface” and click the “Next” button.
