   project(':react-native-confirm-device-credentials').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-confirm-device-credentials/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-confirm-device-credentials')
   

Usage

import ConfirmDeviceCredentials from "react-native-confirm-device-credentials";

ConfirmDeviceCredentials.isDeviceSecure().then(
  (isDeviceSecureResult: boolean) => {
    console.log("Is device secure: " + isDeviceSecureResult);
    if (!isDeviceSecureResult) {
      ConfirmDeviceCredentials.makeDeviceSecure(
        humanReadableMessage,
        securitySettingsButtonLabel
      )
        .then((result: boolean) => {
          console.log("Result of make device secure: " + result);
        })
        .catch((error: any) => {
          console.log("User canceled authentication: " + error);
        });
    }
    if (isDeviceSecureResult) {
      ConfirmDeviceCredentials.keystoreInit(keyName, 10, false).then(
        (keyStoreInitResult: boolean) => {
          console.log("Keystore init result: " + keyStoreInitResult);
          if (keyStoreInitResult) {
            ConfirmDeviceCredentials.storePin(keyName, pin)
              .then((storePinResult: boolean) => {
                console.log("Store Pin result: " + storePinResult);
                ConfirmDeviceCredentials.retrievePin(keyName).then(
                  (decryptedPin: string) => {
                    console.log("Decrypted Pin is : " + decryptedPin);
                  }
                );
              })
              .catch((reason: any) => {
                console.log("Store pin failed: " + reason);
