Overview
The document describes how to integrate Eazyshow platform into an Android application.
Dependencies
Add these dependencies to build.gradle:
implementation 'androidx.appcompat:appcompat:1.4.2'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
Usage
1. Add eazyshow session WebView item to the desired place
<WebView android:id="@+id/eazyshowWebView"
android:layout_width="match_parent"
android:layout_height="match_parent" /2. Get account details
Token
Account ID
3. Initialize User and Assignment objects
final User user = new User("1234567890", "Test", "User");
final Assignment assignment = new Assignment("android-sdk-test", "12345678");
User details are arbitrary values that should be taken from the end client data.
4. Initialize eazyshow Session object
final WebView webview = findViewById(R.id.eazyshowWebView);
final LiveSession session = new LiveSession(this /* Parent activity object*/, webview);
5 . Create class that will handle events coming from the webview by implementing Android Handler.Callback interface Here is an example handler that verifies client photo.
private static class ValidateSelfieCallback implements Handler.Callback {
private final LiveSession session;
private final boolean saveValidationImage;
public ValidateSelfieCallback(LiveSession session, boolean saveValidationImage) {
this.session = session;
this.saveValidationImage = saveValidationImage;
}
@Override
public boolean handleMessage(@NonNull Message message) {
final SessionEvent event = SessionEvent.values()[message.arg1];
Log.v("DemoActivity", "Message received: " + event);
if (event == SessionEvent.EVENT) {
final Bundle bundle = message.getData();
final String eventName = bundle.getString("name");
final String eventData = bundle.getString("data");
switch (eventName) {
case "vsValidateSelfie":
validateSelfie(eventData);
return true;
}
return false;
}
return false;
}
private void validateSelfie(String imageData) {
if (saveValidationImage) {
try {
final String base64image = imageData.replace("data:image/png;base64,", "");
final byte[] decodedString = Base64.decode(base64image, Base64.DEFAULT);
final Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
this.saveToInternalStorage(decodedByte);
final Bundle data = new Bundle();
data.putBoolean("isSuccess", true);
session.sendEvent(SessionEvent.SELFIE_VALIDATION_RESULT, data);
} catch (IOException ioe) {
Log.v("DemoActivity", "Error processing image", ioe);
final Bundle data = new Bundle();
data.putBoolean("isSuccess", false);
session.sendEvent(SessionEvent.SELFIE_VALIDATION_RESULT, data);
}
} else {
final Bundle data = new Bundle();
data.putBoolean("isSuccess", true);
session.sendEvent(SessionEvent.SELFIE_VALIDATION_RESULT, data);
}
}
private void saveToInternalStorage(Bitmap bitmapImage) throws IOException {
final long tsLong = System.currentTimeMillis() / 1000;
final String ts = String.valueOf(tsLong);
final String fileName = "selfie_" + ts + ".jpeg";
final String filePath = this.getGalleryPath(fileName);
final File imageFile = new File(filePath);
try (FileOutputStream fos = new FileOutputStream(imageFile)) {
// Use the compress method on the BitMap object to write image to the OutputStream
bitmapImage.compress(Bitmap.CompressFormat.JPEG, 100, fos);
}
}
private String getGalleryPath(String fileName) {
return Environment.getExternalStorageDirectory() + File.separator
+ Environment.DIRECTORY_DCIM + File.separator + fileName;
}
}
Every event has name and optional data attributes that contain all details about the event itself.
6 . Start the session itself
session.start(ENV_HOST, user, assignment, new JSONObject());
ENV_HOST here is the host where the call should be started (https://dev.eazyshow.com, https://demo.eazyshow.com, etc.) user and assignment are objects initialised in item #3 new JSONObject() is an optional parameters to start the session, these can be used to pass additional details on session start.
