Uiza SDK for Android

Welcome to UizaSDK

Simple Streaming at scale.

Uiza is the complete toolkit for building a powerful video streaming application with unlimited scalability. We design Uiza so simple that you only need a few lines of codes to start streaming, but sophisticated enough for you to build complex products on top of it.

Read CHANGELOG here.

Importing the Library

Step 1. Add the JitPack repository to your build.gradle file

allprojects {
repositories {
maven { url '' }

Step 2. Add the dependency

defaultConfig {
multiDexEnabled true
dependencies {
// for playing VOD, LIVE video
implementation 'com.github.uizaio.uiza-android-sdk-player:uizacoresdk:[latest-release-number]'
// for broadcasting / live streaming
implementation 'com.github.uizaio.uiza-android-sdk-player:uizalivestream:[latest-release-number]'

Get latest release number HERE.

If you are using uiza_android_sdk_player (Version 4.0.9 and above), you will need to import dependencies:

// for playing VOD, LIVE video
implementation 'com.github.uizaio.uiza-android-sdk-player:uizacoresdk:4.0.9'
implementation ''
implementation ''
implementation ''
  • Additionally, if you want to use the Chromecast feature, add the following dependencies to your project:

    // for ChromeCast
    implementation 'androidx.mediarouter:mediarouter:1.0.0'
    implementation ''
  • If advertising support should be enabled, also add the following dependencies to your project:

    // for IMA Ads
    implementation ''
    implementation ''


  • The version of the ExoPlayer Extension IMA must match the version of the ExoPlayer library being used.

  • If you are using both ChromeCast and IMA Ads dependencies, we recommend using dependency '$version' with version >= 18.0.0 to avoid dependency version conflicts

If you are using uiza_android_sdk_player (Version < 4.0.9), you only need to import dependencies:

// for playing video VOD, LIVE, ChromeCast and advertising support
implementation 'com.github.uizaio.uiza-android-sdk-player:uizacoresdk:X.X.X'

Please note if your project uses firebase: firebase-core & firebase-database ... should be same version: Basically, you need to bump all Play Services and Firebase libraries to their latest version (which may be different for each since version 15).

You may use to find the latest version for each library. See also:​

Check example here.

Turn on Java 8 support

If not enabled already, you need to turn on Java 8 support in all build.gradle files depending on ExoPlayer, by adding the following to the android section:

compileOptions {
targetCompatibility JavaVersion.VERSION_1_8

Node, Inside v5:

Init SDK

  1. apiKey : generate HERE.

  2. apiUrl : default is

    public class App extends MultiDexApplication {
    public void onCreate() {
    UizaCoreSDK.initWorkspace(this, apiUrl, apiKey);
  3. If you want show log, install any Tree instances you want in the onCreate of your application class

if (BuildConfig.DEBUG) {
Timber.plant(new Timber.DebugTree());


android:name=".App " <!-- important -->

How to call API?:

Call API by using this function

UizaLiveService service = UizaClientFactory.getLiveService();
listEntityWraps -> {
// onSucces
throwable -> {
// onError

Other API can be used with the same function above.

​API Reference​

This class help you know how to use all Uiza API, please refer to THIS​

How to play the video?:


android:layout_height="wrap_content" />


Create java file MainActivity:

public class MainActivity extends AppCompatActivity implements UZCallback {


android:name=".MainActivity "
android:configChanges="keyboard|keyboardHidden|orientation|screenSize|screenLayout|smallestScreenSize|uiMode" />

In your activity or fragment

  • Play with entity:

    uzVideo = (UizaVideoView) findViewById(;
    // or for VOD"put entityId");
    // or Live"put entityId", true);
  • Play with playlist/folder:

    uzVideo.initPlaylistFolder("put the playlist/folder id here");

Don't forget to add in activity life cycle event:

public void onDestroy() {
public void onResume() {
public void onPause() {
public void onActivityResult(int requestCode, int resultCode, Intent data) {
uzVideo.onActivityResult(resultCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);

If you wanna listen all events of SDK, check the sample here.

This sample help you know how to use all Uiza SDK, please refer to THIS​

More information for AndroidTV, AndroidBox:

You can use this SDK for AndroidTV, AndroidBox as well, but limited some features. We also provide some functions for AndroidTV like:

uzVideo.addUZTVCallback(this); // listen event onFocusChange of components.

Please take a look at module sampletv for more details.

How to customize your skin?

Only 3 steps, you can customize everything about player skin.

Step 1: Create layout uiza_controller_skin_custom_main.xml like THIS:

Please note app:controller_layout_id="@layout/uiza_controller_skin_custom_detail"

Step 2: Create layout uiza_controller_skin_custom_detail.xml like THIS:

  • In this xml file, you can edit anything you like: position, color, drawable resouces...

  • You can add more view (TextView, Button, ImageView...).

  • You can remove any component which you dont like.

  • Please note: Don't change any view ids if you are using it.

Step 3: On function onCreate() of Activity, put this code:



protected void onCreate(@Nullable Bundle savedState) {

Note: If you are using Chromecast, please use UZUtil.setCasty(Activity activity) on function onCreate() of Activity

protected void onCreate(@Nullable Bundle savedState) {

Ex: findView from your custom layout:

TextView tvSample = uzVideo.findViewById(;

That's enough! This code above will change the player's skin quickly. You can build and run your app now.

But if you wanna change the player's skin when the player is playing, please you this function:


This sample help you know how to customize player's skin, please refer to THIS​


  • You should not change the id of the view. Ex: android:id="@id/player_view" Do not change android:id="@id/player_view_0" or android:id="@+id/player_view_0" ...

How to livestream with UizaSDK?:

It's very easy, follow these steps below to implement:


android:layout_height="match_parent" />

In class LivePortraitActivity:

public class LivePortraitActivity extends AppCompatActivity implements UZLivestreamCallback {
// ...

In onCreate():

getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED, WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
uzLivestream = (UZLivestream) findViewById(;

In onResume():

protected void onResume() {

Start a portrait livestream:

if (uzLivestream.prepareStream()) {

To stream in landscape mode, use uzLivestream.prepareStream(true) instead.

Start a livestream and save to MP4 file:

if (uzLivestream.prepareStream()) {

Stop streaming (It auto saves mp4 file in your gallery if you start a livestream with option save local file)


Switch camera:


Allows streaming again after back from background:

uzLivestream.setBackgroundAllowedDuration(YOUR_ALLOW_TIME); // default time is 2 minutes

This sample help you know how to use all Uiza SDK for livestream, please refer to THIS​

For contributors

To run checkstyle for project

  1. Right click on project

  2. Select Analyze > Inspect Code



Supported devices

Support all devices which have Android 4.4 (API level 19) above. For a given use case, we aim to support UizaSDK on all Android devices that satisfy the minimum version requirement.

Note: Some Android emulators do not properly implement components of Android’s media stack, and as a result do not support UizaSDK. This is an issue with the emulator, not with UizaSDK. Android’s official emulator (“Virtual Devices” in Android Studio) supports UizaSDK provided the system image has an API level of at least 23. System images with earlier API levels do not support UizaSDK. The level of support provided by third party emulators varies. Issues running UizaSDK on third party emulators should be reported to the developer of the emulator rather than to the UizaSDK team. Where possible, we recommend testing media applications on physical devices rather than emulators.
