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...

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.

  • can't find android_usb in /sys/class/... Also, I found this number in /cat/proc/cpuinfo – mgulan Jun 03 '14 at 19:59
  • specific location depends on android version. which one are you using? as for the `/proc/cpuinfo` - this number contains the chipset ID. some vendors may choose to use it (or part or some hash function of it) for the USB serial as well. – Alex P. Jun 03 '14 at 20:07
  • Android 2.3.3 Also, can you tell me if chipset ID (serial=) from /proc/cpuinfo can be found on every Android device? – mgulan Jun 03 '14 at 20:12
  • `/proc/cpuinfo` will contain the chip ID for all chipsets supporting it. But it does not help you with finding out the number which `adb devices` shows as very few phone manufacturers use chip ID for USB serial. Unfortunately I do not have any devices that old to check the exact location for that version. – Alex P. Jun 03 '14 at 20:38

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.

Try using the SERIAL string from android.os.build class http://developer.android.com/reference/android/os/Build.html#SERIAL

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

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

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;
    }
