Apply the License Key ​

Initialize the ComPDF SDK and authenticate using the following method. The SDK will automatically distinguish between online and offline activation:

java
String xmlPath = "assets://Android.xml";
// You can also pass the file path of the XML to initialize the SDK
// String xmlPath = "/data/user/0/your_package/files/license/Android.xml";
CPDFSdk.initWithPath(this, xmlPath, (verifyCode, verifyMsg) -> {
  Log.e("ComPDF", "verifyCode: " + verifyCode + ", verifyMsg: " + verifyMsg);
});
