App Development: How To Create Apps


Graphical user interface, application

Android apps are fairly easy to make. While some better level applications need the developer to have good understanding about the Android. This development however there are plenty of apps out there whose development took place without using much knowledge about android development. However let’s check out how you can easily create Android apps at your home.

Step By Step Guide To Creating Android Apps

Here is a step by step guide to developing Android apps without going through a lot of trouble. Let’s check it out.

Begin Installing Android Apps with Android Studio

Download Android Studio and follow the steps to complete the installation process. And then if you did the installing of the software before, this should be a walk in the park. If not, the instructions are available within the download in the “Installer” file. Just follow the steps and you will be good to go.

Create New Project of Android Apps

Once the software is installed and running, select “Create New Project” option. And then give a name to your project. You can save the project file at your desired location or keep the default location. Then keep clicking ‘Next” and proceed. Do remember that only the “Phone and Tablet” option selection should take place on the second screen. After that select the “Blank Activity” option and don’t change any option. Keep proceeding till the black project is ready to be edited. Finally click “Finish”.

Creating First Page Activity

For this step you will have to enter the design view mode of activity_main.xml. Once there, add a button. Write a welcome note for the users. And then place the button underneath it. Make the button “Next”.

Creating Second Activity

Go to the top of the file system tree of the project that you are working on currently. In other words, get ready to create another “Blank Activity” by right-clicking on “app”. And then select the options New >> Activity >> Blank Activity. After you click on “Finish” open activity_second.xml in design view.

In other words, Add a text box just like you did earlier. Therefore now with the text box selected open the ID field under Properties and set that to “text2”. For instance, Now open strings.xml and type whatever message you wish to display on the second page. In other words when done, get back to activity_second.xml and in the properties of the text box write “@string/second_page” in the “text” section.

Compose The Button’s On-Click Action Code

Go to the MainActivity.java and enter the following codes in the onCreate method:

Button button = (Button) findViewById(R.id.button);

button.setOnClickListener(new View.onClickListener() {

@Override

public void onClick(View v) {

goToSecondActivity();

}

});

Under the class MainActivity enter the following code lines:

private void goToSecondActivity() {

Intent intent = new Intent(this, SecondActivity.class);

startActivity(intent);

}

The MainActivity.java will have a ‘+’ right beside import. Add the following lines of code, in case they are not present there:

import android.content.Intent;

import android.view.View;

import android.widget.TextView;

Testing Android Apps

Once you are done with all these, it is time to start the emulator. Moreover, this will take place in the virtual machine test and the buttons and the messages. Therefore now You will need to check whether the buttons are taking you to the next page or not. For instance, whether or not the messages are being displayed.

Above all, this is the basic of the development part of Android apps. After that, you can make further changes and find code snippets on the Internet for various activities.
