当我使用扎根的Android设备作为ADB主机将adb命令 adb设备发送给Samsung S4时,我收到了设备未授权的错误消息。但是,当我尝试使用adb到Samsung Galaxy Nexus时,它工作正常。谁能建议我解决三星S4问题?
When I'm using a rooted Android device as ADB host to send adb command "adb devices" to Samsung S4, I received device unauthorized error message. However when I tried adb to Samsung Galaxy Nexus, it is working fine. Can anyone advise how to solve my Samsung S4 problem?

从客户端电话(adb主机)获取公钥
Get the public key from the client phone (adb host)
cat /data/.android/adbkey.pub
cat /data/.android/adbkey.pub
将上述公钥复制到目标电话的
/ data / misc / adb / adb_keys
位置。 (您可能需要先通过stop adbd
停止adb守护程序)copy the above public key to the target phone's
/data/misc/adb/adb_keys
location. (you may need to stop the adb daemon first withstop adbd
)cat / data / misc / adb / adb_keys
cat /data/misc/adb/adb_keys
验证两个
cat
输出是否匹配。verify both
cat
outputs match.尝试在目标
启动adbd
上重新启动adb守护程序,或者只是重新启动它们。try restarting adb daemon on target
start adbd
or just reboot them.如果在上述步骤中读写ADB KEY时遇到问题,请。请参考更多详细信息
If you are having problems reading or writing to ADB KEYS in above steps, try setting environment variable
ADB_KEYS_PATH
with a temporary path (eg:/data/local/tmp
). Refer to that link it goes into more details"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 (; under Windows) 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"
