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 -lThis 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_idAlternatively, you can query the settings content provider:
adb shell content query --uri content://settings/secure --projection valueUsing 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.
