Android-FIDO integration

Steps to integrate SAWO authentication on your Android application

How to Integrate SAWO SDK to an Android app

  1. Add following line to root build.gradle repositories block

    maven { url '' }
  2. Add this to your app level build.gradle android block

    compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
    kotlinOptions {
    jvmTarget = '1.8'
  3. Add this to your app level build.gradle dependencies block

    implementation 'com.github.sawolabs:Android-SDK:0.1.5'
  4. Sync your project

  5. Go to and create a project and copy the api key and api key secret

  6. Create an Activity in Android Studio to get login success response for this example lets assume it is CallbackActivity

  7. In your MainActivity add a button to login and add following code to its onclick handle


import com.sawolabs.androidsdk.Sawo;
public void onClickLogin(View view) {
new Sawo(
"" // your api key,
"" // your api key secret
"email", // can be one of 'email' or 'phone_number_sms'
CallbackActivity.class.getName() // Callback class name


import com.sawolabs.androidsdk.Sawo
fun onClickLogin(view: View) {
"" // your api key,
"" // your api key secret
"email", // can be one of 'email' or 'phone_number_sms' // Callback class name

8. Get the response payload in the CallbackActivity


import com.sawolabs.androidsdk.ConstantsKt;
Intent intent = getIntent();
String message = intent.getStringExtra(ConstantsKt.LOGIN_SUCCESS_MESSAGE);
// continue with your implementation


import com.sawolabs.androidsdk.LOGIN_SUCCESS_MESSAGE
val message = intent.getStringExtra(LOGIN_SUCCESS_MESSAGE)
// continue with your implementation

9. Recommended: Verify the payload sent by sdk from your backend

Python example:

import requests
data = {
'user_id': payload_sent_from_sdk['user_id']
res ='', data=data)
# Match the verification token in response with sdk payload
if res.status_code == 200:
response_data = res.json()
if response_data['verification_token'] \
== payload_sent_from_sdk['verification_token']:
# continue with your implementation for example add the user to your db
