Trialy.io Android SDK

Trialy makes it super easy to create a free trial for your in-app-purchases. Trialy takes care of the heavy lifting for you (using server-side checks with customizable grace periods to allow offline use, for example) so you can focus on developing an amazing app.

  • Add the library to your app using gradle
  • Grab a free API key from here

For documentation and additional information see the website.

compile 'io.trialy.library:trialy:1.0.5' 
}

Usage

Initialize the library in your main activity's onCreate() method:

 @Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

 //Initialize the library and check the current trial status on every launch

Trialy mTrialy = new Trialy(mContext, "YOUR_TRIALY_APP_KEY");

mTrialy.checkTrial("YOUR_TRIAL_SKU", mTrialyCallback);

  
}

Add a callback handler:

private TrialyCallback mTrialyCallback = new TrialyCallback() {

@Override

public void onResult(int status, long timeRemaining, String sku) {

 switch (status){

  case STATUS_TRIAL_JUST_STARTED:

//The trial has just started - enable the premium features for the user

 break;

  case STATUS_TRIAL_RUNNING:

//The trial is currently running - enable the premium features for the user

break;

  case STATUS_TRIAL_JUST_ENDED:

//The trial has just ended - block access to the premium features

break;

  case STATUS_TRIAL_NOT_YET_STARTED:

//The user hasn't requested a trial yet - no need to do anything

break;

  case STATUS_TRIAL_OVER:

//The trial is over

break;

  default:

Log.e(TAG, "Trialy response: " + Trialy.getStatusMessage(status));

break;

 
}

}

}
;

To start a trial, call mTrialy.startTrial("YOUR_TRIAL_SKU", mTrialyCallback); Your app key and trial SKU can be found in your Trialy developer dashboard.

If you're using a "per Google account" trial, also add the GET_ACCOUNTS permission to your AndroidManifest.xml (and request it within your app on Android 6.0+):

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