手机:T708(OS: Android 4.3)

手机开发者选项中USB调试已经打开,在电脑命令行下输入adb devices,显示手机未认证

D:/Program Files/HBuilder/tools/1.0.31>adb devices
* daemon not running. starting it now on port 5037 *

网上搜了一圈,几经折腾,什么adb kill-server/start-server、重新开关USB调试、撤回USB除错授权,甚至坑爹的重刷手机系统都试过,也没有搞定。

 

没办法,折腾adb源代码去,看这里

https://android.googlesource.com/platform/system/core/+/d5fcafaf41f8ec90986c813f75ec78402096af2d

源码没看到,先看到一大段英文,英文水平一般,直接搬原文:

 

adb: Add public key authentificationSecure adb using a public key authentication, to allow USB debuggingonly from authorized hosts.When a device is connected to an unauthorized host, the adb daemon sendsthe user public key to the device. A popup is shown to ask the user toallow debugging once or permanantly from the host. The public key isinstalled on the device in the later case. Other keys may be installedat build time.On the host, the user public/private key pair is automatically generated,if it does not exist, when the adb daemon starts and is stored in$HOME/.android/adb_key(.pub) or in $ANDROID_SDK_HOME on windows. If needed,the ADB_KEYS_PATH env variable may be set to a :-separated (; underWindows) list of private keys, e.g. company-wide or vendor keys.On the device, vendors public keys are installed at build time in/adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys.ADB Protocol change:If the device needs to authenticate the host, it replies to CNXNpackets with an AUTH packet. The AUTH packet payload is a random token.The host signs the token with one of its private keys and sends an AUTH(0)packet. If the signature verification succeeds, the device replies witha CNXN packet. Otherwise, it sends a new AUTH packet with a new token sothat the host can retry with another private key. Once the host has triedall its keys, it can send an AUTH(1) packet with a public key aspayload. adbd then sends the public key to the framework (if it has beenstarted) for confirmation.

 

 

在电脑的win7系统上查看ANDROID_SDK_HOME,命令行 echo %ANDRIOD_SDK_HOME%

天啊,指向一个不存在的目录,

 

将电脑环境变量中的ANDRIOD_SDK_HOME删除,重新运行adb devices,手机上出现授权提示,问题解决。
