android implicit intent edit failed to load image -

-

this implicit intent invoke image editing apps on device:

startactivity(new intent(intent.action_edit).setdataandtype(myuri,      getmimetype(myuri)).setflags(intent.flag_grant_read_uri_permission |       intent.flag_grant_write_uri_permission));

and how getmimetype:

public string getmimetype(uri uri) {     string mimetype = null;     if (uri.getscheme().equals(contentresolver.scheme_content)) {         contentresolver cr = getcontentresolver();         mimetype = cr.gettype(uri);     } else {         string fileextension = mimetypemap.getfileextensionfromurl(uri                 .tostring());         mimetype = mimetypemap.getsingleton().getmimetypefromextension(                 fileextension.tolowercase());     }     return mimetype; }

for apps crashes load:

on app sketch_camera invisible page loads , disables interaction app.

on app airbrush loads app crashes message "failed load image".

is related minimum sdk version mine 16? i've tested on minimum sdk version of 9 , no change in result.

is there else should add intent work apps?

i've tried putextra , doesn't help:

.putextra(intent.action_edit, myuri);

i've gallery apps on device , of them launch sketch_camera , airbrush without problem.

what's happening here? i'm confused after 2 days of struggling phenomena.

it's file created path of 1 media store file querying mediastore.images.media.external_content_uri

there no guarantee other app has rights location, or your app has rights location. example, image on removable storage. besides, the file uri scheme being banned cross-app usage, anyway.

use content uri instead. example, in this sample app, query mediastore videos. given cursor named row positioned @ particular video, generate uri via:

videouri=     contenturis.withappendedid(       mediastore.video.media.external_content_uri, row.getint(row.getcolumnindex(mediastore.video.media._id)));

this uri both works own purposes (e.g., hand picasso thumbnail, hand videoview playback) , handing third-party apps (e.g., action_view playback).

other changing base uri 1 queried against (mediastore.images.media.external_content_uri), same basic code should work you.

also, rid of flags intent. intent points own contentprovider, not case in either original code or uri create withappendedid().
