Android Slices Tutorial

Continuing in last post here I gone explain how to create Slices for your application. If you have not read it please go through my previous post Understanding Slices to get your setup ready.

First Get your setup ready

You need to install Slice Viewer apk to view your slices. Download latest relase of slice viewer apk from https://github.com/googlesamples/android-SliceViewer/releases & install it using command:

adb install -r -t slice-viewer.apk

where :

-r: replaces existing application
-t: allow test packages

Now you can view your Slice by running the following command:

adb shell am start -a android.intent.action.VIEW -d slice-content://com.hiteshsahu.slicedemo/

It is pretty much like loading different pages of a website by changing URLS

For example:

content://com.hiteshsahu.slicedemo/ : will gone load home slice
content://com.hiteshsahu.slicedemo/about : will gone load about slice
content://com.hiteshsahu.slicedemo/contact : will gone load contact slice

and so on see the result below.

Every time you gone launch a new slice with this adb command then that slice will be automatically get added in Slice Viewer demo app. Which you can see any time later.

Same can be achieve with the help of Android studio but I prefer command line tool. COmmand line tool is less complicate and less overhead.

Uninstall sliceviewer

If you have uninstalled sliceviewer.apk by drag and drop in Launcher app then chances are you might no longer will be able to install it back via adb command. This is a weird bug I found. In that case you will need to uninstall sliceviewer using this command.

 adb  uninstall com.example.android.sliceviewer

Building Custom Slices

As already described in my previous post Understanding SLices you can use Android Studio to create Slices as shown in pic below:

Steps to build slices

Install SliceViewer APK:

 adb install -r -t slice-viewer.apk

Download, Build, Install & Launch this project.

Execute this command from adb termainal:

  adb shell am start -a android.intent.action.VIEW -d slice-<uri_from_below>

For example to Launch Home screen from Slice execute. Note the "-" after slice.

  adb shell am start -a android.intent.action.VIEW -d slice-content://com.hiteshsahu.slicedemo/

Basic SLices

BasicSliceProvider class contain example of how we can create aslice and use Peending Intent to send data to the App

Similarly replace <uri_from_below> with this uris to launch Slice mapped to screens.
