Everything about ActivityResult API
As an Android developer, we all know that we need to manage the runtime permissions while picking any image, video from the camera, or storage. We need to write more boilerplate code to manage request code for each and every permissions and that’s too annoying sometimes. There are also some third-party libraries are available to manage that all things like Dexter, PermisionsDispatcher, etc. But sometimes we expect something to handle with native codes rather than to use third-party libraries.
So that’s why I have thought to write the blog and share my knowledge with the community which helps you to handle runtime permissions, pick any content from storage with the new ActivityResult API from AndroidX.
What is ActivityResultAPI?
ActivityResult API provides some built-in contracts which commonly use while developing an android app such as :
StartActivityForResult()
RequestMultiplePermissions()
RequestPermission()
TakePicturePreview()
TakePicture()
TakeVideo()
PickContact()
CreateDocument()
OpenDocumentTree()
OpenMultipleDocuments()
OpenDocument()
GetMultipleContents()
GetContent()
Benefits:
- No need to manage to get the result from Fragment or Activity using different request codes.
- No need to write boilerplate code to handle the runtime permission
