Getting Android Device Identifier from ADB and Android SDK

Getting Android Device Identifier from ADB and Android SDK

21 May 2024 Stephan Petzl Leave a comment Tech-Help

Identifying a unique Android device identifier can be crucial for various development and testing purposes. This guide provides step-by-step instructions on how to retrieve a unique identifier using both ADB (Android Debug Bridge) and the Android SDK.

Using ADB to Retrieve Android Device Identifier

One of the simplest methods to retrieve an Android device identifier is through ADB. The command to get the device’s serial number is straightforward:

adb devices -l

This will list all connected devices along with their identifiers. The output will look something like this:

List of devices attached
    YOGAA1BBB412    device

Retrieving ANDROID_ID via ADB Shell

Another method to get a unique device identifier is by querying the ANDROID_ID. This can be done using the following ADB shell command:

adb shell settings get secure android_id

Alternatively, you can query the settings content provider:

adb shell content query --uri content://settings/secure --projection value

Using Android SDK to Retrieve Device Identifier

Within the Android SDK, you can retrieve the device’s serial number programmatically. Here is a simple example using Java:

String serialNumber = android.os.Build.SERIAL;

For ANDROID_ID, you can use:

String androidId = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);

Practical Use Cases

Knowing how to retrieve device identifiers can be particularly useful when managing multiple devices during development or testing. For example, identifying devices by their serial numbers can help in automating tests across different hardware configurations.
