android : file Uri to Content Uri. (converting)

Question

I have two type of Uris.

type one :

content://media/external/images/media/465

content://media/external/images/media/466

type two :

file:///storage/emulated/0/DCIM/Camera/20151112_185009.jpg

file:///storage/emulated/0/testFolder/20151112_185010.jpg

What is difference and how to convert file uri to content uri?

Because, file uri is just causing error. When I call method :

ContentResolver contentResolver = getContentResolver(); fis = (FileInputStream) contentResolver.openInputStream(fileTypeUri);

how do I fix this?

for contentResolver.openInputStream to work you need to use content:/... like Uri — pskink

Try It :)

public static Uri getImageContentUri(Context context, File file) { String filePath = file.getAbsolutePath(); Cursor cursor = context.getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new String[] { MediaStore.Images.Media._ID }, MediaStore.Images.Media.DATA + "=? ", new String[] { filePath }, null); if (cursor != null && cursor.moveToFirst()) { int id = cursor.getInt(cursor .getColumnIndex(MediaStore.MediaColumns._ID)); Uri baseUri = Uri.parse("content://media/external/images/media"); return Uri.withAppendedPath(baseUri, "" + id); } else { if (file.exists()) { ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.DATA, filePath); return context.getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); } else { return null; } } }

If you're trying to share data that is stored as part of your app with another app you'll need to use a content:// scheme and not a file:// scheme. This can be accomplished using the FileProvider class found here: https://developer.android.com/reference/android/support/v4/content/FileProvider.html.

By using the FileProvider class you can more precisely and more securely define what files your app can share.

Though be aware that external-cache-path and external-files-path don't work despite what the documentation says. See: how to set FileProvider for file in External Cache dir for more info.
