¿Cómo puedo conseguir que el tipo mime de un archivo tenga su Uri?
Tengo una Lista de Uri obtenidos con la Galería y la Cámara. Estos Uris son así: content://media/external/images/media/94
. ¿Cómo puedo obtener su tipo mime?

Puedes probar
ContentResolver cR = context.getContentResolver();
MimeTypeMap mime = MimeTypeMap.getSingleton();
String type = mime.getExtensionFromMimeType(cR.getType(uri));
Editar:
mime.getExtensionFromMimeType(cR.getType(uri))
Devuelve - > "jpeg"
cR.getType(uri);
Devuelve "image/jpeg" que es el valor esperado.

Este método devuelve la extensión del archivo (jpg, png, pdf, epub, etc..).
public static String getMimeType(Context context, Uri uri) {
String extension;
//Check uri format to avoid null
if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
//If scheme is a content
final MimeTypeMap mime = MimeTypeMap.getSingleton();
extension = mime.getExtensionFromMimeType(context.getContentResolver().getType(uri));
} else {
//If scheme is a File
//This will replace white spaces with %20 and also other special characters. This will avoid returning null values on file name with spaces and special characters.
extension = MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(new File(uri.getPath())).toString());
}
return extension;
}

En lugar de esto:
String type = mime.getExtensionFromMimeType(cR.getType(uri));
Haz esto:
String type = cR.getType(uri);
Y obtendrás esto: image/jpeg
.

Para Content
Uri
.
ContentResolver cr = context.getContentResolver();
mimeType = cr.getType(contentUri);
Para File
Uri
.
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(fileUri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
Para ambos, funciona tanto para Content
como para File
.
public String getMimeType(Context context, Uri uri) {
String mimeType = null;
if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
ContentResolver cr = context.getContentResolver();
mimeType = cr.getType(uri);
} else {
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
}
return mimeType;
}
