SDK Initialization

License Key​

The Docutain SDK for React-Native needs a valid, non-expired license key in order to work. On Android the license key is bound to the applicationId in your build.gradle and on iOS to the CFBundleIdentifier in your info.plist. Any attempt to use a license key in an app with a different applicationId or CFBundleIdentifier will fail.

Trial license​

The Docutain SDK is a commercial product and requires a paid license for production use. In order to get a trial license, please visit our website via https://sdk.docutain.com/TrialLicense to generate a trial license key.

Production license​

To get information about the SDK's functionality and pricing and to purchase a production license, please contact us.

Initialize the SDK​

In order to use any functionality of the SDK, you must initialize it first. Add the following code to your App constructor:

import DocutainSDK from '@docutain/react-native-docutain-sdk';

export class App extends React.Component {
  constructor(props: any) {
    super(props);
    this.InitDocutainSDK();
}

async function InitDocutainSDK() {
  if(!await DocutainSDK.initSDK("YOUR_LICENSE_KEY")){
    //init of Docutain SDK failed, get the last error message
    const error:string = await DocutainSDK.getLastError();
    //your logic to deactivate access to SDK functionality
  }
}
caution

If the initialization fails, you are responsible to deactivate access to SDK functionality.

Logging​

The SDK writes certain information into a log file. You can get the log file by calling DocutainSDK.getTraceFile(). You can send this log file to us if you have any issues/bugs with the SDK. The Logger has certain levels that you can set depending on your needs. However, we suggest to leave the level to it's default value which ensures that in case of any issues/bugs we can get all the information we need from you.

//get the log file
const traceFile:string = await DocutainSDK.getTraceFile();

//set the log level
DocutainSDK.setLogLevel("VERBOSE");

Depending on the log level, some temporary files get written. These files, if any, will be deleted everytime the SDK starts, so you don't need to worry about spamming the files dir.

If you like, you can delete these files manually by using DocutainSDK.deleteTempFiles(false).
