License Key
A license key is unique to a package name.
If you change the package name of an app or create an app with a new package name, you must create a new key for the new package name.
The license key can be created from License Manager.
If you have created a new key, use the following code to add the key.
ARActivity.java
protected void onCreate(Bundle savedInstanceState) { … MaxstAR.init(getApplicationContext(), "your license key"); … }
If you add a wrong license key, the ‘Invalid Signature' watermark will be displayed.
