Call Recorder App in Android Studio - Step by Step Tutorial


Here in this tutorial, we are going to build a call recorder app using the Android studio. You'll need to follow step by step tutorial to make this on your own. I'll be providing a link to the source code at the end of the tutorial you can download it or fork it to modify pre-written code.

Firstly, you need to add a few dependencies to your project to build. gradle file. these dependencies are used by the app




Open the layout file in the res folder in your project. Now we need to make a basic UI (User Interface) for our app. Open main_activity.xml file and paste the code below into it.





Now we need to make some layouts to show up the data recorded. In simple, to show up the recorded audio name, time & date when recorded and some other parameters. To show them up on a recycler view we need to make layout files which are inflated to recycler view as list.

The first layout is date_layout.xml this makes organised recordings according to the date they were recorded. Just paste the below code to the layout file.



Now we make a layout file for no_date_layout.xml this is because we don't want to show the update on every recording on the same day.
just paste the below code.



Now we make the toggle switch which turns on and off call recorder service. This will be shown on the toolbar of the app.
Make a new XML resource in layouts folder in res directory call it switch_layout.xml.
paste the code below to it.



Now we need to make a new place holder called record_list.xml which is used to show up the recorded item.



Now make a new layout resource and call it record_noname_list.xml and paste the code below to it.



Now make a directory called XML in the res folder. make a file named provider_paths.xml in XML directory you created.
This file finds the path for the recorded files by our app.



Now make a new directory in res folder and name it as menu and add an XML resource called mainmenu.xml.




Now we are done with the UI. Let's continue the java coding in the next part of this tutorial. Feel free to comment down any problems or questions.
