Android How can I call Camera or Gallery Intent Together

If I want to capture image from native camera, I can do:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent, IMAGE_CAPTURE);

If I want to get image from gallery, I can do:

Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,
                        "Select Picture"), SELECT_PICTURE);

I am wondering how can put the above two together.
That means GET IMAGE FROM GALLERY OR CAPTURE PHOTO Select an action

Is there any example code to do it? Thanks.

Let's say that you have two intents. One that would open a camera, one that would open a gallery. I will call these cameraIntent and gallerIntent in the example code. You can use intent chooser to combine these two:

Kotlin:

val chooser = Intent.createChooser(galleryIntent, "Some text here")
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf(cameraIntent))
startActivityForResult(chooser, requestCode)

Java:

Intent chooser = Intent.createChooser(galleryIntent, "Some text here");
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { cameraIntent });
startActivityForResult(chooser, requestCode);

This is, as you asked, how you can put the two together (without having to make your own UI/ dialog).

In fact your dialog title is "select an action" means the dialog is a Intent chooser actually. not a user customed dialog. The every single item presents a Intent.

public void click(View view) {
        File file = getExternalFilesDir(Environment.DIRECTORY_DCIM);
        Uri cameraOutputUri = Uri.fromFile(file);
        Intent intent = getPickIntent(cameraOutputUri);
        startActivityForResult(intent, -1);
    }

    private Intent getPickIntent(Uri cameraOutputUri) {
        final List<Intent> intents = new ArrayList<Intent>();

        if (true) {
            intents.add(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI));
        }

        if (true) {
            setCameraIntents(intents, cameraOutputUri);
        }

        if (intents.isEmpty()) return null;
        Intent result = Intent.createChooser(intents.remove(0), null);
        if (!intents.isEmpty()) {
            result.putExtra(Intent.EXTRA_INITIAL_INTENTS, intents.toArray(new Parcelable[] {}));
        }
        return result;


    }

    private void setCameraIntents(List<Intent> cameraIntents, Uri output) {
        final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        final PackageManager packageManager = getPackageManager();
        final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
        for (ResolveInfo res : listCam) {
            final String packageName = res.activityInfo.packageName;
            final Intent intent = new Intent(captureIntent);
            intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            intent.setPackage(packageName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, output);
            cameraIntents.add(intent);
        }
    }

You may need solve permissions by yourself if run on OS >= 23

Here's my demo:(Appearance differences since OS different)
