#Does service start will null intent android studio code

We will use the ID to refer to the Image View in our Java Activity, updating it to display any image received from the SEND Intent.

Inside the layout, add the following to display a received image:

#Does service start will null intent android studio code

Replace any existing code in the layout file with the following Relative Layout outline:Īlter the 'tools:context' attribute if you chose a different Activity class name. Open the main layout file and switch to the XML tab to edit the code. Let's design the app to display the received text String or image. Here is the 'DataReceiver' app appearing in the share list for the Gallery application, through which various image types can be shared. If you need your app to receive multiple data items of one of your MIME types, you can include the SEND_MULTIPLE Action as well as/instead of the SEND Action alone. There are lots of other types you can receive, including audio, video, message, and application. You can optionally specify particular text or image types. This indicates that the app will receive any text or image type. Next we need to indicate the MIME types the app is going to receive: This tells Android that when other apps launch a SEND Intent this app may receive what is being shared. Inside the new element, add an Action element specifying the SEND Intent Action: By adding another Intent Filter element, we are specifying additional options for launching the app. This is where we define the Actions that can launch the app - the existing Intent Filter specifying the normal options for when the user launches from the homescreen or device application menu. Find the section containing your app's main Activity - you should see an Intent Filter element there already, indicating MAIN action and LAUNCHER category.Īfter the existing Intent Filter element, inside the main Activity element, add another Intent Filter: Open it in Eclipse and switch to the XML editor tab. In order for your app to appear in the chooser list presented when the user attempts to share data from another app, you need to alter the Project Manifest file. Eclipse should create Activity and layout files for your app.
