问题:
I am using following code to pick an image from the gallery. When I test it with Samsung Galaxy S4, it directly goes to Gallery that is what I want actually.
BUT, when I test my code on LG Optimus II device, it shows a dialog gives an option to choose either Gallery or Picture. In other words, it adds one more layer which I do not want.
Both devices have KitKat 4.4.2 operating system.
public static void showFileChooser(Activity activity) { Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_PICK); activity.startActivityForResult(Intent.createChooser(intent, "Select Picture"), 1); }

That is because there are two activities on that device that support ACTION_PICK of image/* files. There can be zero to N such activities, depending on what apps are on the device. This will include both pre-installed apps and apps that the user installed themselves. These will range from local file managers to general cloud providers (e.g., Dropbox) to image-specific apps (e.g., Instagram).
In other words, it adds one more layer which I do not want.
Then do not use ACTION_PICK. You are delegating to a third-party app; it is up to the user, not you, what third-party app the user wishes to use.

if you want Gallery then
Intent pickImageIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
please use for api 19 or above
if (Build.VERSION.SDK_INT < 19) { Intent intent = new Intent(); intent.setType("image/jpeg"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent, "Select image to promote"), GALLERY_INTENT_CALLED); } else { Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); intent.addCategory(Intent.CATEGORY_OPENABLE); intent.setType("image/jpeg"); startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED); }
