(for all 3 capture types)

I would drop the use of getTempDirectoryPath to not write in app temp dir, because this path is cleaned up by the system while such captured audio/image/video should be available afterward in the device media dirs (correct Environment.DIRECTORY_..) as a common practice.

See the Taking photos doc : https://developer.android.com/training/camera/photobasics#TaskPath, really similar to what you have done

  • use File.createTempFile
  • with specific values and correct Environment.DIRECTORY_.. for each of our 3 types
  • and possibly more <external-files-path entries inside mediacapture_provider_paths.xml to match that

The Android training link I shared gives example of using getExternalFilesDir (with corresponding paths.xml) but this writes to the app private dirs and thus requires to "Add the photo to a gallery" to be similar to the auto-indexing of previous Android and iOS mediacapture code!

Note: If you saved your photo to the directory provided by getExternalFilesDir(), the media scanner cannot access the files because they are private to your app.

Do you agree? Or to which dirs will we agree to write by default here?

Any way to capture and write all 3 types to public dirs?

I suggest ".mp4" instead of ".avi" as it the file extension I get for video capture with previous code without these FileProvider changes

Is it save to assume file extension to begin with? I imagine this could differ depending on the underlying camera app.

@breautek I think you're right :/

"but" one more link in Android training docs should be interesting to follow : https://developer.android.com/guide/topics/media/camera.html#saving-media
for its getOutputMediaFile(), with output switch for MEDIA_TYPE_IMAGE or MEDIA_TYPE_VIDEO = "IMG_x.jpg" // "VID_x.mp4"

a similar output extension of .mp4 can be found in CameraX training too

Ah, well if the docs shows an assumption of .mp4 I guess it's fine to assume!

I suggest to remove the check on videoAbsolutePath != null ; no such check for audio or image, and the absolutePath is always defined when this method is called

req.results.put(createMediaFileWithAbsolutePath(this.videoAbsolutePath));
} else {
pendingRequests.resolveWithFailure(req, createErrorObject(CAPTURE_NO_MEDIA_FILES, "Error: data is null"));

the target file is always defined now with file extension/type? (video always as avi/mp4, and audio as wav) so this block about .3gpp files may be removed?
