3. Prerequisites of android app development
•If you want to create a basic android app, you should have basic knowledge on coding languages
like JAVA, C, C++.
•Concept/idea to showcase or implement your app
System specifications to check:
The following are the required software requirements which you need to install if you are not
having before you start creating the app. Doesn't have!
Download and install the both Java tool Kit and Android Studio

Hardware Requirements: Ensure that you are having these hardwarespecifications
- RAM 4GB, Hard disk 500GB

4. Wireframe
Have a great idea to develop app? Then now draw wireframe for your basic app and
ensure that you are making use of this tool to represent the proposed functionality of the
app and the structure of the app.
There should be proper attention on the graphical elements and the functionality of the
app. When this is achieved properly, then developing the code will be easier and you will
also know how the end users are going to use it. It is also helpful to make desired changes
if you wish things are not as per the specifications.
For example I want to develop a
basic Login Demo app with login &
sign up buttons functionality. Here is
my wireframe

5. Impeccable Design
Design is the element which attracts the people. When they like the graphics and the
colors used for the theme of the app, then they would spend some more time and know
the details of the app or its services. So make sure that you are vigilant about the colors
and as well the images and the graphics which you put into it.

6. Steps How to Create android app (Login Demo)
Once you are done with the wireframe and then added the images and the designs of
the app, now it is time to start the coding as per the requirements.
Step 1:
Open the Android studio and you can follow
the bellow steps to create new app.
