If you are just arriving at this page; and you are not familiar with with creating Android Apps, we suggest you begin with our tutorials:
Coding Android App Pages
and How To Create a Simple App in Android
From there follow along with each tutorial lesson.
AIDE and ANDROID STUDIO
We are using AIDE(a mobile coding environment using language java/xml), to create these tutorial apps on our
tablet(7" screen) that has android version 5.0.
Once we build and RUN our app; we then install the app on this same tablet; and the app is also installed on a smart phone that has android version 6.
AIDE can be installed on any android version from 4 - 8.
We are using the AIDE coding editor to code our pages; and then to Create - RUN our apps. AIDE is a SDK coding environment for android devices like a tablet or smartphone.
AIDE has a free and paid version.
Once you create your apps code pages, you need to RUN the app to build your apk package; then you INSTALL it on your tablet or smartphone.
For info on using AIDE, gohere
can also create; RUN your apps using the code in these tutorials, with Android Studio. Android Studio is for desktop computers. Choose Java XML as the programming language.
Android Studio is free to install and use for your android app development. Although not as convenient as testing your app on an actual android device; you can test
your newly created app in Android Studio using its' android emulator.
Complete Example Codes are available for each of our tutorials. With these example codes you can make a functioning android app in
either AIDE or Android Studio.
First, create a java/xml android template app using AIDE, (or Android Studio). Then you can get the code for this app from the EXAMPLE CODE section on this page.
Replace the code on the pages you need to(with our tutorial code); in order to create this app.
Sometimes, new pages have to be created.
All the other coded pages in your app
can remain as they are; they don't need to be changed.
This is the App - Fragments
It has 2 fragments in the layout, coded by using the weight attribute; meaning each fragment is given a % weight of the layout total.
for each fragment can be whatever you choose. For this app; fragment 1 is 30% of the layout, and fragment 2 is 70% of the layout. This means that fragment 2 is
a larger section of the layout.
Where - How To Use Fragments
Fragments are added to your app interface. You can have as many fragments as you like. Fragments reside within your app activity. Because they do,
you do not have to define them in the manifest file as you do with your layout file (typically main.xml, MainActivity.java).
Fragments can be used for any purpose in your app. This tutorial shows how they can be added as a 'weighted fragment'. Each fragment has its own
section of the app screen layout.
Creating - Naming Your App Using AIDE
When creating your app,(from left menu) choose:
Create New Project;
New Android App(gradle, android Java/xml)
Hello World App Java/xml
if your using the original version of AIDE
You can name your app whatever you like; if your using the name as shown in our example code use;
for the App Name and,
for the package name(next line) use:
If you want to name it differently, you can, just change the code to whatever name you choose where it says, com.aac.fragmentexample, in the coded pages, usually at the
top of the java class pages like- MainActivity.java
The Coded Pages
Code for the app - Fragments
For this app you will use these coded pages:
1 layout file, main.xml, where you define your 2 fragments; located at res/layout/,
2 fragments, you must create 2 xml pages, one for each fragment; and put them at res/layout/fragment1.xml; and res/layout/fragment2.xml,
2 fragment java pages, you must create 2 java pages; one for each fragment; where you define the java class code for each fragment; put them at src/java/Fragment1.java and src/java/Fragment2.java
1 strings.xml page, where you define the app name Fragments, located at res/values/strings.xml.
Since this app has no images; we don't have to add any to our drawable-hdpi folder.
The folder src/res/drawable-hdpi also has our ic_launcher.png image; but we don't need to add it because it was
added automatically when we created our android template app.
EXAMPLE CODE - Code For This Tutorial
JUST USE YOUR MOUSE to copy the code for this tutorial
App Name is 'Fragments - located at AppProjects/Fragments in AIDE, open the AIDE app, then open App Projects, THEN select the 'Fragments',
app from your files hierachy(left menu); then click on any file from the app, like strings.xml Make sure at top of page, the app name 'Fragments' is there next to
AppProjects like so: AppProjects/Fragments, then you know you have the proper App.
Once a file is in the editor, you can edit, save it, then RUN your APP, Install,
and Open your app.
Make sure you SAVED EACH PAGE,(or choose automatic saving in AIDE settings) before you RUN your code. SAVE, RUN, INSTALL, OPEN, your App. Once it has been
installed on your tablet, you can open it Simply by Clicking on the Android little green App Icon,with the wording 'Fragments' on your tablet. It will
be with your other installed apps.
If you make further changes to this App, you need to SAVE, RUN, UPDATE, INSTALL, OPEN the app.
This free script provided by
for creating Android Apps on your tablet or cell phone(android).
Free and Paid - with Free, create java/xml android template apps, and there is a couple free android coding lessons.
create java/xml android template apps, and you can create a 'keystore' for your app, so you can publish your apps to the marketplaces like Google Playstore and Amazon.
