I want to add a folder of free images to my app, so that the user easily finds it with
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
startActivityForResult(Intent.createChooser(intent,
"Select image"), SELECT_IMAGE);
(Next step would be do let user click something to download another folder, perhaps at a cost.)
I only find ways to add images to the app so that direct links to the images can be shown in the app, but I didn't figure out how to let those image be part of the selection shown with the code above.

I want to pick single and multiple images from gallery, I have tried below code
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
but it allows only multiple images, I can't select single one. I want pick single as well as multiple images.
There is no any default way to pick multiple images from android Gallery. You have to make your own media picker for the same. Please refer following link to get source code for picking multiple media. here
We have a website where on mobile and specifically android devices when people want to change their "avatar" image the options that show up when we click on "upload" does not have the "Gallery". Instead it has "Documents" is there a way to define what to show and what not to show?
We are using PHP if that matters at all for development.
Please see below image.
well it depends on which intent you have used for upload button, in my opinion the most appropriate intent to call when you want user to select an image would be
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
it would make the gallery and other photo handling apps visible in the chooser dialog.

I am trying to open gallery on Nexus 7 with Android 6.0. It does not have in built gallery, but it does have the Google Photos app.
I am using the following code to open the gallery :
Intent i = new intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// Always show the chooser (if there are multiple options available)
startActivityForResult(Intent.createChooser(i, "Select Picture"), PICK_IMAGE_REQUEST);
The above code works well in all the versions below 6.0. And Please note that I am already using RUN TIME PERMISSIONS for accessing gallery and have given the permission to access gallery / or externa storage.
Now when the code is executed, I get a transparent screen with heading "Select Picture" and in the middle a text No Apps can perform this action.
Now what do I do to pick or choose image and use in my app.
Any help is appreciated.
Thanks
I am using the following code to open the gallery
That code has nothing to do with a "gallery". That code is requesting to pick a piece of content from a particular collection of content. There may be zero, one, or several activities on the device that offer to support that Intent structure.
The above code works well in all the versions below 6.0
Only on devices that happen to have one or more activities that satisfies that Intent structure.
Now what do I do to pick or choose image and use in my app.
Intent i = new intent(Intent.ACTION_GET_CONTENT).setType("image/*");
// use PackageManager to see if there is anything that supports this
// Intent structure, or just blindly make the following call and handle
// the ActivityNotFoundException
startActivityForResult(i, PICK_IMAGE_REQUEST);
I am using this code , so that only gallery opens and not any other option to pick image
There is nothing in your code that limits it to just a "gallery".
Not allowed to comment because I don't have enough points. But here's just a suggestion, how about if you just passed the intent directly? Like this:
startActivityForResult(i, PICK_IMAGE_REQUEST);
Use this line of code rather than what you have done
Intent i = new intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, PICK_IMAGE_REQUEST);
I have a small app where some people can have a 1:1 chat with each other. Now I want to implement a possibility to share some files (images, sounds, whatever,...).
My problem: I need a possibility to let the user choose such a file. Since I did not find some kind of "file dialogue" for Android: what is the best way to do this?
I do not need a ready-to use solution but just some hints/ideas how this could be done out of an app.
Thanks!
You can have one Button in your screen and clicking on that button let user choose a file from gallary using below code,
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
startActivityForResult(Intent.createChooser(intent, "Select Picture"),SELECT_IMAGE);
I find this code here to open the gallery from my own btn:
btnGallery.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), 0);
}
});
It works, but when I click on a photo it exit the viewer.
I guess it because the "createChooser".
How can I change it to only view the photos and not to choose them?
As far as I know this is impossible.
If you had access to a full class name of an activity to start the Gallery app you could call it as you usually do it Activity.startActivity(Context context, Class clazz). But Gallery classes is an internal API which you have no direct access to.
Well, Gallery app is accessible via throwing an appropriate Intent like the one in your sample code. By setting action name intent.setAction(Intent.ACTION_GET_CONTENT) you request the behavior you've got (browse all images, select one, get back to the caller activity with a uri of a selected image). There is also another possible action Intent.ACTION_VIEW, and if set with a uri of an image it causes Gallery to show that image for you. But that's all we can request from Gallery (there are no other predefined actions to suit your needs - just to browse images).
So, a way out is to create your own custom image browser activity.
