ACTION_GET_CONTENT : How to get file-ending when searching for multiple file types?

Question

I am using an Intent to let the user select a file, and after the user has done that I want to know what kind of file-type the selected file is. The intent: ``` Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType("*/*"); ``` In my onActivityResult I want to extract the path from the intent through intent.getData() and all of it's "submethods" (getScheme(), getLastPathSegment() etc). However, I only get the Uri for the selected file. Example of Uris': ``` Uri: content://media/external/audio/media/15185 //This is an audiofile Uri: content://media/external/audio/media/20 //Another audiofile Uri: content://media/external/images/media/20577 //this is a picture Uri: file:///storage/emulated/0/testWed%20Apr%2017%2011%3A10%3A34%20CEST%202013 //This is a file ``` I've seen solutions of how to get the absolute path when the user is only allowed to chose images or audios. But how do I do I get the absolutePath (the real path with the name and file-ending, e.g. MyPicture.jpeg) i…

Accepted Answer

By file-ending I'm assuming you mean the file extension? (i.e. mp4)

If so you can use the `ContentResolver` to get the mimetype:

```
String mimeType = getContentResolver().getType(sourceUri);
```

This will give you the mimetype assuming they are within the `MediaStore` which they should if you have the content `Uri`. so you'll get something like "image/png", "video/mp4", etc.

Then you can use `MimeTypeMap` to get the file extension from the mimetype:

```
String extension = MimeTypeMap.getSingleton().getExtensionFromMimeType(mimeType);
```

Note that you should never substring the mimetype after "/" to get the extension as some mimetype does not use its extension such as ".mov" files which has the mimetype "video/quicktime"
