How I can get the mime type of a file having its Uri?

Question

I have a List of Uris obtained with the Gallery and the Camera. These Uris are like this: content://media/external/images/media/94. How I can get its mime type?

Answer 1

for Content Uri.

ContentResolver cr = context.getContentResolver();
mimeType = cr.getType(contentUri);

for File Uri.

String fileExtension = MimeTypeMap.getFileExtensionFromUrl(fileUri
            .toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
            fileExtension.toLowerCase());

for Both, works for Content as well as File.

public String getMimeType(Context context, Uri uri) {
    String mimeType = null;
    if (ContentResolver.SCHEME_CONTENT.equals(uri.getScheme())) {
        ContentResolver cr = context.getContentResolver();
        mimeType = cr.getType(uri);
    } else {
        String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
                .toString());
        mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
                fileExtension.toLowerCase());
    }
    return mimeType;
}
