Android: How to get the Serial Number as shown in About Device, Status with Java

Question

On my Android Tablet I go to Settings -> About Device -> Status In this screen I find a serial number with a length of 11 characters. I would like to read this serial number with Java. Anyone an idea how to do that?

Answer 1

Use

String x = Build.SERIAL

For more details check this out. This is the device serial number.

For MDN or MEID of the device depending on which radio the phone uses (GSM or CDMA), try

TelephonyManager tManager = (TelephonyManager)myActivity.getSystemService(Context.TELEPHONY_SERVICE);
String uid = tManager.getDeviceId();

and include the permission in the manifest file:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Answer 2

Very old question, but perhaps the solution from dev here still helps:

public static String getManufacturerSerialNumber() {
String serial = null; 
try {
  Class<?> c = Class.forName("android.os.SystemProperties");
  Method get = c.getMethod("get", String.class, String.class);
  serial = (String) get.invoke(c, "ril.serialnumber", "unknown");
} catch (Exception ignored) {}
return serial;
}

Answer 3

Try this:

TextView tv = (TextView)findViewById(R.id.text);
String serial = Build.SERIAL;
tv.setText(serial);
