android - "adb install" returns error: protocol fault (no status)

Question

I have created and ran a couple of android emulators, now I'd like to install application on them. Here is the story of me trying it a couple of times:

$ adb -s emulator-5562 install xxx.apk 
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: protocol fault (no status)
- waiting for device -
^C
$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
emulator-5554   device
emulator-5556   device
emulator-5558   device
emulator-5560   device
emulator-5562   device
$ adb -s emulator-5562 install xxx.apk 
error: protocol fault (no status)
- waiting for device -
^C
$ killall adb
$ killall adb
adb: no process found
$ adb -s emulator-5562 install xxx.apk 
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

    pkg: /data/local/tmp/xxx.apk <- sometime it reaches upto here but it stays there for ever
^C

can you please help me what else I can do to check the problem? thank you

Answer 1

“adb install”返回错误：协议错误（无状态）：

解决方案是

\platform-tools使用终端转到并执行以下命令

set ADB_TRACE=1
adb start-server

---

要从 ADB 设备列表中删除模拟器：

打开“Android虚拟设备管理器”->选择要删除的模拟器->点击删除按钮。

见下图

Answer 2

对我来说，它原来是一个过时的 ADB 服务（过时的平台工具）。
它仍然可能是一个过时的驱动程序，但由于驱动程序大部分时间都没有更新，请确保您已通过 SDK 管理器安装了最新版本的 Android SDK 平台工具：

我还读到，当您安装 Android Studio 时，可能会出现问题。然后您必须通过“工具 -> Android”禁用 ADB 集成（取消选中）。之后，使用adb kill-server或简单地重新启动计算机来重新启动您的 adb 服务器。

Answer 3

我遇到了它，因为连接了多个 ADB 设备。

断开除我正在使用的设备之外的所有设备对我有用。
