Select multiple images from android gallery -

so trying achieve opening gallery in android , let user select multiple images. question has been asked frequently i'm not satisfied answers. because found interesting in de docs in ide (i come on later) , thereby don't want use custom adapter vanilla one.

now code selecting 1 image is:

intent intent = new intent(); intent.settype("image/*"); intent.setaction(intent.action_get_content); startactivityforresult(intent.createchooser(intent,"select picture"), 1); 

now people on , other websites wil tell you have 2 options:

1) not use action_get_content action_send_multiple instead.
1 doesn't work. 1 according docs sending files , not retrieving , that's does. when using action_send_multiple got window opened @ device have select application send data to. that's not want, wonder how people got achieved solution.. miss something?

2) implement custom gallery. last option consider because imho it's not searching because have style myself , why heck can't select multiple images in vanilla gallery?

there must option this.. interesting thing i'v found this:
i found in docs description of action_get_content.

if caller can handle multiple returned items (the user performing multiple selection), can specify extra_allow_multiple indicate this.

this pretty interesting. here referring use case user can select multiple items?

later on in docs:

you may use extra_allow_multiple allow user select multiple items.

so pretty obvious right? need. following question is: can put extra_allow_multiple? sad thing can't find no in developers.android guide , not defined constant in intent class.

anybody can me out extra_allow_multiple?

the extra_allow_multiple option set on intent through intent.putextra() method:

intent.putextra(intent.extra_allow_multiple, true); 

your code above should this:

intent intent = new intent(); intent.settype("image/*"); intent.putextra(intent.extra_allow_multiple, true); intent.setaction(intent.action_get_content); startactivityforresult(intent.createchooser(intent,"select picture"), 1); 

note: extra_allow_multiple option available in android api 18 , higher.
