I'm using the following code:
Intent fileIntent = new Intent(Intent.ACTION_GET_CONTENT);
fileIntent.setType("image/jpg|image/png|image/jpeg");
startActivityForResult(fileIntent, REQUEST_FILE);
I believe that code should allow me to select any jpg, png or jpeg file, but it doesn't.
On the other hand changing fileIntent.setType("image/jpg|image/png|image/jpeg"); to fileIntent.setType("image/*"); allows to select the file. But it also allows to select another image files I don't want to.
What needs to be corrected in fileIntent.setType("image/jpg|image/png|image/jpeg"); so it allows to choose files of those types and not other ones?
You can only specify a single mimetype with setType(), instead apply an extra with the key Intent.EXTRA_MIME_TYPES with an array of mimetypes:
fileIntent.putExtra(Intent.EXTRA_MIME_TYPES, Arrays.asList("image/png", "image/jpeg").toArray());
I have found that even when providing a list of mimetypes you may still need to apply intent.fileType("*/*"); to the intent regardless, however, the list of mimetypes will take preference.
