In cases where mobile data or WiFi connection is limited, downloading large media files from your Ona account to ODK Collect may be challenging. In this case, you can manually add their media files to their device.
Below are step by step instructions on how to add media files to your /odk/forms directory on your device’s storage:
Yes, it is possible to introduce questions that will launch the smartphone device’s camera during data collection.
The Tutorial XLSForm is used as an example to illustrate how to include questions that allows one to capture an image. In your XLSForm, the question type for such a question should be image. In ODK Collect, the image capture relies on the configuration and capabilities of your device’s camera application.
You either launch the camera by tapping on Take Picture or by selecting an image stored in devices storage by tapping on the Choose Image button.
When collecting data via Enketo the camera cannot be launched, but the image will be uploaded from your local drive.
Yes, it is possible to introduce questions that will launch device’s audio or video recorder during data collection. For example, to collect take an audio or video recording.
For example, you would write your questions as follows in your XLSForm:
|audio||audio_recording||Take an audio recording|
|video||video_recording||Take a video recording|
When collecting data using ODK Collect on your device you can either tap on Record Sound or Record Video button. You can also select a recorded audio or video file from your device by tapping on Choose Sound for audio and Choose Video for video.
Audio capture relies on the configuration and capabilities of the device’s audio recorder app. On newer 4.x devices and tablets, the inbuilt audio recorder app may not provide a good user experience when launched from ODK Collect. To get audio capture to work on devices that do not come with a built-in audio recorder, installing RecForge Lite which is a free third party app and may also provide a better experience.
On the Project page, select the form that you wish to view the media data captured then follow the instructions below:
