Android get Gallery image Uri path

Question

In an Activity, I can choose an image from the Gallery, and I need its Uri path (in the log, the Uri path for my test image is /content:/media/external/images/media/1).

I'm getting this error though:

08-04 02:14:21.912: DEBUG/PHOTOUPLOADER(576): java.io.FileNotFoundException: /content:/media/external/images/media/1 (No such file or directory)
08-04 02:14:32.124: WARN/System.err(576): java.io.FileNotFoundException: /content:/media/external/images/media/1 (No such file or directory)

Is this the correct format of a file path? Or should I make it to be something like sdcard\...\image.png?

to anyone who may also have this problem: you do need a absolute path of your file. I'll post the method above you can use to convert this uri to path – Leathern

Post it as an answer if you have a solution. – Susurrate

I meant, post it as an answer. Since it answers the question so other people see it as answered. – Susurrate

Answer 1

public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    startManagingCursor(cursor);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Leathern

For anyone else who gets here, note that managedQuery is a method of an activity, so you may need to provide an activity. – Interpreter

A second note is that the cursor should be closed cursor.close() – Interpreter

from the docs: Warning: Do not call Cursor.close() on a cursor obtained using this method, because the activity will do that for you at the appropriate time. – Meteoroid

I would like to mention that managedQuery is now deprecated. If somebody developes the app for Android API 4 and higher, add support library v4 and use this code: CursorLoader loader = new CursorLoader(context, uri, projection, null, null, null); Cursor cursor = loader.loadInBackground(); instead of Cursor cursor = managedQuery(uri, projection, null, null, null); – Clos

cursorloader target api 11 (at least for me) – Polycotyledon

crash when you pick an old picture from "Photos" – Zillion

I get the absolute uri but when I check the file.length() it's 0. Someone has one idea why? – Saint

not compatible with all sdks , try my answer ... its full . – Lexicostatistics

MediaStore.Images.Media.DATA is also deprecated, this method will no longer work – Conchitaconchobar

Answer 2

val inputStream = context.contentResolver.openInputStream(uri)

is all you need.

Crust

How on earth this answer hasn't got any up votes yet? This is EXACTLY ALL WHAT WE NEED. Thank you Sir! – Gravelly

This is too easy. Does it only work for certain SDK versions or something? – Honeybunch

@DavidKennedy ContentResolver#openInputStream() was added in API level 1 so don't think so – Crust

great, but how do i get path from this InputStream? – Lobation

@Lobation you don't, the idea is to abstract away file paths – Crust

Now I just need to get a file path from this. Might be able to convert InputStream to OutputStream and save the file to a different location (I need to copy it anyway). IMO this whole Uri business is ridiculous. Why return this useless abstract Uri thing from an Image Gallery Picker, rather than an actual path to the actual file, on the actual device? LIke real world stuff. Crazy I know – Weinberger

@Weinberger Android uses Uri instead of raw file paths because images picked from Android's media picker may not actually be stored on user's storage (think Dropbox or Google Photos for example). Just because you don't understand something fully doesn't make it ridiculous. – Crust

@Crust Yeah that's a good point, but the hoops you have to jump through for this are pretty funny. So it's impossible for a Uri to provide an absolute path if it's not a remote file? I just wish it wasn't so unwieldy to deal with. – Weinberger

I don't think it is. You get a URI whose content can be read using a couple lines of code, especially with Okio. Accessing raw paths was always dangerous because they can be cached longer than their files' lifetime. What happens if a file is deleted? If you really want file paths, copying them to your app storage is a safe solution. – Crust

this works for all SDK's Versions :
