Android Device Names Build Status

This tiny Android library transforms a device model name into something people can understand. For example, a useless

Samsung Galaxy Note4
with a single method call. :tada: It currently recognizes about 15k devices, including all Google Play supported devices.

It does not require network connectivity, ever. No, really.

To use it, add the following to your list of dependencies:

compile 'com.github.tslamic:dn3:3.0'

There are two classes you can use:

  1. DeviceNames
    use this if all you need is a single query.
  2. DeviceNamesDatabase
    for multiple queries. Don't forget to close it afterwards!

RxJava2 is supported out of the box. Obtaining a

instance is easy:
  .subscribe(names -> doSomethingWith(names));

but good ol' callbacks are supported too, in case you don't feel reactive:

  new AndroidDeviceNames.Callback() {
    public void onReady(@NonNull DeviceNames instance) {
      String name = instance.currentDeviceName(); 

You can obtain an instance of

in a similar fashion. After you're done using it, don't forget to explicitly call
. For example:
protected void onStart() {
    new AndroidDeviceNames.Callback() {
      public void onReady(@NonNull DeviceNamesDatabase instance) {
        database = instance;

@Override protected void onStop() { super.onStop(); if (database != null) { database.close(); } }


come with three methods:

| method | description | | -----: | :---------- | |

| Returns a user-friendly current device name, or
if the model is unknown. | |
currentDeviceName(String fallback)
| Same as above, but returns
if the model is unknown. | |
deviceName(String model, String fallback)
| Returns a user-friendly name for the specified
, or
, if model is unknown. |

Not backwards compatible with v1 or v2, sorry.

If you've been using AndroidDeviceNames v1 or v2, please note that this version is not backwards compatible. Updating should be trivial, result in minimal code change and is highly encouraged.


Special thanks to @corcoran for making numerous improvements to the lib.
