The device log will be uploaded to SAP Cloud Platform Mobile Services reusing the OKHttpClient and SettingsParameters from the flow.

How to make a log upload request reusing values provided by the flows framework

When the app is opened, the restore or onboard flow will have initialized an OKHttpClient to communicate with Mobile Services. The OKHttpClient instance will be reused for the log upload method call. Additional values such as the serviceURL are available which would be needed in an online or offline OData request.

Step 1: Add code to upload the log

Add the uploadLog method below to the bottom of the MainActivity class.

public void uploadLog() {
    LOGGER.debug("In uploadLog");
    myLogUploadListener = new Logging.UploadListener() {
        @Override
        public void onSuccess() {
            LOGGER.debug("Log upload completed");
            Toast.makeText(getApplicationContext(), "Log upload completed and was successful!",
                    Toast.LENGTH_LONG).show();
            Logging.removeLogUploadListener(myLogUploadListener);
        }

        @Override
        public void onError(@NonNull Throwable throwable) {
            LOGGER.debug("Log upload encountered an error with message: " + throwable.getMessage());
            Toast.makeText(getApplicationContext(), "Log upload failed with error message: " + throwable.getMessage(),
                    Toast.LENGTH_LONG).show();
            Logging.removeLogUploadListener(myLogUploadListener);
        }

        @Override
        public void onProgress(int percentUploaded) {
            LOGGER.debug("Log upload progress: " + percentUploaded);
        }
    };

    Logging.addLogUploadListener(myLogUploadListener);

      // String serviceURL = flowContext.getOnboardingParameters().getSettingsParameters().getBackendUrl();
      // String deviceID = flowContext.getOnboardingParameters().getSettingsParameters().getDeviceId();
      OkHttpClient okHttpClient = flowContext.getOkHttpClient();
      SettingsParameters sp = flowContext.getOnboardingParameters().getSettingsParameters();
      Logging.uploadLog(okHttpClient, sp, Logging.UploadType.MERGE);
}

The above method uploads the existing log to Mobile Services and displays the result of the action. Notice that the Logging.uploadLog method requires an OkHttpClient and SettingsParameters variables that are retrieved from the flowContext.

Add the following line to the onUploadLog method.
