more than one device/emulator, please specify the serial number

To specify the serial number of a specific device/emulator, you can use the following command:

adb -s <serial_number> <command>

Replace `<serial_number>` with the actual serial number of the device/emulator you want to target. For example, if you have multiple devices/emulators connected and want to install an APK on a specific device with the serial number "ABC123", you can use:

adb -s ABC123 install app.apk

This way, you can differentiate between multiple devices/emulators connected to your system.

error: more than one device/emulator Performing Push Install adb: error: failed to get feature set: more than one device/emulator

这个错误通常是由于同时连接了多个 Android 设备或模拟器导致的。解决方法是使用以下命令之一指定要安装应用程序的设备或模拟器：

1. 使用设备 ID 安装应用程序：

   adb -s <device_id> install <path_to_apk>

2. 使用模拟器名称安装应用程序：

   adb -s <emulator_name> install <path_to_apk>

请将 `<device_id>` 或 `<emulator_name>` 替换为您要安装应用程序的设备或模拟器的 ID 或名称，将 `<path_to_apk>` 替换为您要安装的应用程序的 APK 文件路径。

error: more than one device/emulator

This error message appears when there are multiple devices or emulators connected to the computer at the same time and the command being executed is ambiguous as to which device to target.

To resolve this error, you need to specify which device or emulator to target by using the `-s` flag followed by the device ID or name. For example:

adb -s emulator-5554 install myapp.apk

This command installs the `myapp.apk` file on the emulator with the ID `emulator-5554`.

To get the list of connected devices and their IDs, you can use the `adb devices` command. This will display a list of all connected devices and emulators along with their unique IDs.

adb devices

Once you have identified the device or emulator you want to target, use the `-s` flag to specify it in the command.
