Get Android device ID shown in adb

Question

How can I get Android device ID to string (with Java code Android 2.2+) that is shown when I connect it to computer ( example from eclipse "Serial number" field ) or enter "adb devices" to cmd? I know it's not ANDROID_ID or telephonyManager.getdeviceId() or Build.SERIAL but I can't find what is it...

Answer 1

the only universal way is to pull the number from USB interface settings:

/sys/class/android_usb/android0/iSerial

Other than that it is up to every vendor to choose the way to store the serial number. Some of them choose not to populate ro.serialno property.

Answer 2

If you need the id shown by the adb devices command, then it is indeed Build.SERIAL .

The value shown in Eclipse seems to be just a concatenation of Build.MANUFACTURER , Build.MODEL and Build.SERIAL .

At least these are the results when testing on Nexus devices.

Answer 3

尝试使用android.os.build类http://developer.android.com/reference/android/os/Build.html#SERIAL中的SERIAL字符串

Answer 4

add android:name="android.permission.READ_PHONE_STATE" to your manifest

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);    
String id = telephonyManager.getDeviceId();

Answer 5

If u want to get android_id , u can use

 private String getAndroidID() {
            String androidId = Settings.Secure.getString(getContentResolver(),Settings.Secure.ANDROID_ID);
            return androidId;
        }

In case u want device id , u can use

private TelephonyManager getTelephonyManager() {
        TelephonyManager telephonyManager = ( TelephonyManager )getSystemService( Context.TELEPHONY_SERVICE );
        return telephonyManager;
    }

private String getIMEIStringOfDevice() {
       String imeiString = getTelephonyManager().getDeviceId(); 
        return imeiString;
    }
