The iOS SDK allows you to integrate the DaCast player securely in your mobile applications. To get started download the archive from this link and open it in a folder.

In your Xcode application right click on the project, select "Add Files to ..." and add both THEOplayerSDK.framework and DacastPlayerIOS.framework from the archive.
In the project configuration make sure the frameworks are listed in both Linked Frameworks and Libraries and Embedded Binaries. You should end up with something like this: In ViewController.swift import the Dacast Player SDK:

import DacastPlayerIOS

Next add the following code to your viewDidLoad function:

let player = DacastPlayer(contentIdStr: "104301_f_506288", adUrl: "https://cdn.theoplayer.com/demos/preroll.xml")
player.frame = CGRect(x: 0, y: 0, width: 400, height: 400)
player.addAsSubview(of: self.view)

Let's break down this code. First we create a DacastPlayer object with 2 arguments: the contentId and an adUrl.
The contentId is found in the javascript embed code in the publish settings section of your backoffice. The adUrl can be from any ad provider and is optional, removing it will just play the video with no ad.
Next we set a size for our player with the frame property and add the player to the current view with addAsSubview (you can also use insertAsSubview)

From there you can get the instance of the THEOplayer by calling player.getTHEOplayer() and refer to the official THEOplayer documentation.

The Android SDK allows you to integrate the DaCast player securely in your mobile applications. To get started download the archive from this link and open it in a folder.

In Android Studio, right click on your app in the project explorer select New > Module. Scroll down and choose Import .JAR/.AAR Package. On the next screen, for the File Name, browse to where you uncompressed the archive and select DacastAndroidSDK.aar and click Finish. If an error pops up open the settings.gradle file for the project and add the module name to the comma separted list after the include statement.
Repeat the steps to import theoplayer-android-sdk.aar. In the end your settings.gradle file should look like this: Now you need to add both modules as a dependency for your app. Go to File > Project Structure...
Before adding the dependencies, there is currently a bug in the THEOplayer SDK if your Target Sdk Version is API 28. Go to the Flavors tab and make sure your Target Sdk Version is set to 27 and the Min Sdk Version set to API 16 or above.
Next go to the Dependencies tab, click the + button at the bottom, select 'Module dependecy' and add both modules as a dependecy.
Click the + again, select Library dependency, in the search bar type 'gson' and hit enter. Add com.google.code.gson as a dependency.
Your dependency tab should look similar to this:
In your MainActivity.java file, create a new field of type DacastPlayer

private DacastPlayer player;

If everything went well Android Studio should ask you to import the com.dacast.dacastandroidsdk.DacastPlayer namespace.
You also need to relay the pause, resume and destroy even to the player

@Override
protected void onPause() {
    super.onPause();
    player.onPause();
}

@Override
protected void onResume() {
    super.onResume();
    player.onResume();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    player.onDestroy();
}

Now let's initialise the player field in the onCreate method.

player = new DacastPlayer(this, "104301_f_506288"/*, "https://cdn.theoplayer.com/demos/preroll.xml"*/);
ConstraintLayout layout = findViewById(R.id.mainlayout);
player.getView().setLayoutParams(
    new ConstraintLayout.LayoutParams(
        ConstraintLayout.LayoutParams.MATCH_PARENT, 
        ConstraintLayout.LayoutParams.MATCH_PARENT
    )
);
layout.addView(player.getView());

As you can see we instantiate a DacastPlayer object giving it the content id and optionally an url to a preroll ad. Then we just insert it in the main layout, assuming you have set up an id of mainlayout for it.

From there you can get the instance of the THEOplayer by calling player.getTHEOplayer() and refer to the official THEOplayer documentation.
