I’ve connect my device via TCPIP at 5555 port.

Result of adb devices

adb devices
List of devices attached
192.168.0.107:5555      device

Device IP: 192.168.0.107:5555

Running scrcpy gives the result:

Press any key to continue...

I tried using scrcpy -s 192.168.0.107:5555 as the ip address was returned as the device serial when using adb devices

Which gave the same issue.

Then I used adb shell getprop ro.serialno to get my device’s serial no ; 8HUW4HV4Y9SSR4S8

Then with this new serial no I tried: scrcpy -s 8HUW4HV4Y9SSR4S8 which gave a new error:

INFO: scrcpy 1.10 <https://github.com/Genymobile/scrcpy>
adb: error: failed to get feature set: device '8HUW4HV4Y9SSR4S8' not found
ERROR: "adb push" returned with value 1
Press any key to continue...

This might be because the device is not connected via usb and the default serial returned is the Local ip address.

I’ve tried all previous solutions. Did not work.

The Android Debug Bridge (ADB) is a versatile tool that allows developers to communicate with Android devices via command-line tools. The adb shell command opens a terminal interface to interact with an Android device or emulator’s shell. However, when operating with multiple devices or emulators, developers are likely to encounter errors like «error: more than one device/emulator» that prevent them from executing their intended commands. This article aims to shed light on this error and provide solutions to overcome it.

Understanding the ‘error: more than one device/emulator’ Error

When using the adb command, the error «error: more than one device/emulator» usually occurs when multiple Android devices (physical or emulators) are connected to the computer by USB or the network. In this case, ADB is unable to determine which device to interact with as well as which Android emulator to communicate with.

Additionally, this error message may occur when attempting to run a command on all devices at once, but ADB is unable to differentiate between them. This error can be frustrating for developers working with multiple devices and emulators as it prevents them from moving forward with their development tasks.

Ways to Resolve ‘error: more than one device/emulator’ Error

The ‘error: more than one device/emulator’ error is usually not that critical and can be resolved with some adjustments to the ADB command. Below are some solutions to this problem.

Solution 1: Specify the Android device in the ADB command

The simplest way to resolve this error is to specify the device or emulator to which the ADB command should be sent. This is accomplished by appending the «-s» option followed by the device ID to the ADB command. The device ID can be found by running the «adb devices» command. Here’s an example of how to interact with one specific device:

Where «deviceID» is the ID of the specific device, which can be found by running the following command:

This tells ADB which device to interact with, and the error should no longer appear.

Solution 2: Use the ADB command to specify which emulator to run

If the error occurred when trying to start an emulator using ADB, a possible solution to overcome it is by specifying the emulator to which the ADB command should be sent. The emulator can be identified using its port number, which can be determined by running the «adb devices» command. Here’s an example of how to run an emulator using ADB:

adb -s emulator-port -e emu

Where «emulator-port» is the port number of the specific emulator.

Solution 3: Close Other Emulators

When multiple emulators are actively running on your computer, ADB might not know which emulator you’re trying to connect to. Therefore, one of the most straightforward solutions is to close all running emulators except the one you want to work on and then start the ADB command again.

Solution 4: Reconnect the Android Emulator or Device

In some cases, the error may occur due to poor connectivity between the emulator or device and the computer. In such instances, unplugging the device from the USB port or closing and reopening the emulator can help resolve the error messages.

Final Thoughts

The ‘error: more than one device/emulator’ error message is a common issue that occurs when multiple devices or emulators are connected to the computer while working with ADB. The solutions recommended above provide various ways to overcome the error and get back to conducting your intended ADB command. By following these simple steps, you should be able to work through the error and maintain your productivity without losing momentum in your development tasks.

here’s some additional information on each of the previous topics:

ADB Shell:

ADB shell is a command-line tool that enables you to interact directly with an Android device or emulator’s shell. It provides a terminal interface for executing various commands on your device or emulator, such as installing and uninstalling apps, accessing system files, and more. ADB can be a valuable tool for Android developers and power users alike, as it allows you to perform many advanced operations that are not possible through the device’s regular user interface.

ADB Devices:

The «adb devices» command is used to find the list of all connected android devices to your computer. It lists all available devices that are attached to your computer, both physical devices and emulators. Before executing any other ADB command, you must ensure that the device is connected and detected by the ADB server. The «adb devices» command helps you identify the status of the device by displaying its ID and verification status.

ADB Error: More Than One Device/Emulator:

The «error: more than one device/emulator» error usually occurs when more than one Android device or emulator is connected or running on your computer. ADB is unable to determine which device to send a command to in this case and fails to execute the command. The error message can be resolved by specifying the device or emulator to which the ADB command should be sent, or by closing other emulators that might interfere with the ADB command.

ADB Commands:

ADB provides a wide range of commands for interacting with Android devices and emulators, including installing and uninstalling apps, accessing system files, taking screenshots, recording videos, and more. Some commonly used ADB commands include «adb install» to install an app onto a device, «adb uninstall» to uninstall an app from a device, «adb logcat» to view the system log, and «adb shell» to launch the device shell.

In conclusion, ADB is a powerful tool that can help developers and power users to interact with Android devices and emulators more efficiently. By understanding some essential ADB commands, users can perform many advanced operations that are not possible through the device’s regular user interface. And with the solutions provided for the common «error: more than one device/emulator» error, ADB users can quickly resolve the issue and be on their way to achieving their development goals.
