I need to select an image from SD card in my android application.
I'm using URI to run device apps by below code:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
I want to know if it is wise to handle URI tasks like above task by myself in my app or could it cause any trouble something like this.
Yes its fine and risk free. Incase you are trying to get images from Local storage, this is a good library :

I'm using this code for some years now and it worked fine:
final Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
sharingIntent.setType("audio/mpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM,
SoundProvider.getUriForSound(getContext(), sound));
getActivity()
.startActivity(Intent.createChooser(sharingIntent,
getContext().getString(R.string.share)));
My SoundProvider generates a URI that starts with content:// which is picked up by a FileProvider (actually the same SoundProvider). This provider reads an audio file from my raw folder.
The sounds was playable directly in WhatsApp (and not a generic file) and shown with the correct title from the ID3 tags.
This has worked flawlessly and still does with Telegram/Dropbox etc. but up until a recent WhatsApp update from a few months ago it fails with the message "Sharing failed please try again".
Is anyone aware of any changes made by WhatsApp and has encountered something similar?
Try this:
Uri uri = Uri.parse(audioPath);
Intent shareIntent = new Intent();
shareIntent.setType("audio/*");
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
I had to work around this by copying the sounds to the external-files-dir.
I don't know why whatsapp suddenly doesn't accept files from the raw directory served by a FileProvider anymore while other apps still do without any problems.
please help
how can i do preselection all for user in a native android gallery ?
here is a code
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
galleryIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, multiple);
galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Pick an image");
activity.startActivityForResult(chooserIntent, IMAGE_PICKER_REQUEST);
its working fine, but initial stage 0 files are selected
thanks
There is no means of pre-selecting anything when using ACTION_GET_CONTENT, let alone pre-selecting everything.
Also note that ACTION_GET_CONTENT is not tied to a gallery app, and there is no single "native Android gallery" app across the ~10,000 Android device models.
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 am using the following code to pick images.
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
photoPickerIntent.setData(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(Intent.createChooser(photoPickerIntent, getActivity().getResources().getString(R.string.select_picture)), 1);
Its working fine but it only let me to choose images from default Photos application. I want to pick images from "Gallery" application even in today's latest devices. I don't know how WhatsApp is doing this even for Lollipop.
I am using This code in my app and it works fine for me..
intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/* video/*");
startActivityForResult(intent, 3);
I am trying to use Android gallery to pick image. Launching gallery is easy for that purpose
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
However, I need to limit images that are shown in the gallery to specific path on device (i.e. to show images from single folder only). Is this possible to do and how?
Sorry, no this is not possible.
Also you are using this Intent protocol wrong. As per http://developer.android.com/reference/android/content/Intent.html#ACTION_PICK this protocol expects that you put the content: URI of the data set you want the picker to select from.
That said, you should consider ACTION_PICK deprecated. The modern action is ACTION_GET_CONTENT which is much better supported; you will find support of ACTION_PICK spotty and inconsistent. Unfortunately, ACTION_GET_CONTENT also does not let you specify a directory.
Why not ?
Intent galleryIntent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivity(galleryIntent)
Good luck with..
