How To Show More Providers With Action_open_document

I want to use the android system dialog provided as part of the Storage Access Framework to open a file. I do this with Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); int

Solution 1:

Use 'ACTION_GET_CONTENT:

Intentintent=newIntent(Intent. ACTION_GET_CONTENT);
intent.setType("application/pdf");
startActivityForResult(intent, EDIT_REQUEST);

Solution 2:

We also had this issue. It seems there are multiple ways to get a chooser.

Here's what we did:

                val fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri.toString())
                MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension.toLowerCase())
            }
            return mimeType
        }

    }

So, suppose you wish to choose a video file, you can do as such:

privateval mimeTypeMap = MimeTypeMap.getSingleton()
privateval videosMimeTypes = arrayOf(mimeTypeMap.getMimeTypeFromExtension("mkv"), mimeTypeMap.getMimeTypeFromExtension("mp4"), mimeTypeMap.getMimeTypeFromExtension("3gp"))

...
val intentForChoosingVideos = ThirdPartyIntentsUtil .getPickFileChooserIntent(this,null,
            true, "videos/*", videosMimeTypes)
            ?: getPickFileIntent(this, "video/*,", videosMimeTypes)

You can change it to handle other file types of course. Here's for image files:

privateval mimeTypeMap = MimeTypeMap.getSingleton()
privateval imagesMimeTypes = arrayOf(mimeTypeMap.getMimeTypeFromExtension("png"), mimeTypeMap.getMimeTypeFromExtension("jpg"), mimeTypeMap.getMimeTypeFromExtension("webp"))

...
val intentForChoosingImages = ThirdPartyIntentsUtil .getPickFileChooserIntent(this, null,
            true, "image/*", imagesMimeTypes)
            ?: getPickFileIntent(this, "image/*,", imagesMimeTypes)

It will try to have the extended one, and if it fails, it will try to get a chooser of which app to use. If that fails, it will return null.

Note that for some reason, "Google Photos" app doesn't allow to choose just videos, so if you want to include it, use a more generic form:

val intentForChoosingVideos = ThirdPartyIntentsUtil.getPickFileChooserIntent(this, null,
            false, true,"*/*", videosMimeTypes)
            ?: ThirdPartyIntentsUtil.getPickFileIntent(this, "video/*,", videosMimeTypes)
