How do I display a list of all MIME types supported by a given Android device?

Question

I'm trying to displaying a device supported format programmatically. i have found this on the internet. the question is, how to display those ? please help me, im newbie in Android development.

Here is the code for checking file format of the device.

    package com.android.mmscommon;

Here is the full list : https://www.iana.org/assignments/media-types/media-types.xhtml

It is referenced in the android documentation here: https://developer.android.com/guide/topics/providers/content-provider-creating.html#MIMETypes

Note that these MIME types are supported only if the user has the appropriate app for it. I don't think that you can display the supported MIME types programmatically. However you can check if the one that you want to use is supported using code like this :

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(someUri, "YOUR_MIME_TYPE_HERE");
if(intent.resolveActivity(activity.getPackageManager()) != null)
{
    lActivity.startActivity(intent);
}
else
{
    Log.w(TAG, "There is no application for this MIME type");
}
