The official IDE forANDROIDAPPS isANDROIDSTUDIO.It doesn't cost anything and supports two languages.You have great control over what your app does.Why don't you program your app in it?If you don't know the basics of Java, please look at How to Write Your First Program in Java for an introduction.You can learn how to make a basic app in this website.
Step 1: You can download the Android studio.
You need to download the correct version of the operating system.You are using Windows, Mac, or Linux.The download may take a while.Make sure to get the version for your system to download and install.Go to the studio's website in a web browser.Make sure the correct operating system is listed below the green button when you click it.Next to "I have read and agree with the above terms and conditions" is a box.The blue button says to open the install file.Go to the on-screen instructions.
Step 2: The only way to install the dependencies is to use the Linux 64-bit only.
If you don't have a 64-bit Linux computer, you will have to install additional packages.The command line on a system that uses apt is apt-get.If you want to install Linux on your system, open the Software Center and click on the icon that resembles a magnifying glass.There is an icon that resembles a drawing compass in the shape of an "A" inside a green circle.
Step 3: You need to extract the archive.
If you downloaded an install file on Windows or Mac, you should skip this step.You can change to the directory where you downloaded the archive.Pick the "Extract here" option if you click on it in the file manager.If you want to change the name of the file you just downloaded, you can enter "tar -xf downloadName.tar.gz" into the command line.
Step 4: It's time to launch the Android studio.
Double-click on the file if you downloaded it.If you download and extract an archive, open the Terminal and change the directory to the "bin" of the files.This is done by typing into a keyboard.The file "studio.sh" can be run by typing.
Step 5: Decide if you want to import settings.
Select if this is your first time using the program.Select and specify where you saved the settings if you used it before.
Step 6: Should usage data be sent to Google?
This is not a decision that will affect the installation or programming process.
Step 7: Wait for a window to open.
It will be called the "Android Studio Setup Wizard".Click on to move on.
Step 8: Decide if you want to do a standard install or a custom install.
If you don't have any special requirements, you should select "Standard".
Step 9: Click Finish once the components are downloaded.
You can do something else while this takes some time.Click on them when they are downloaded.
Step 10: Open the studio.
It has an icon that resembles a drawing compass in the shape of an A inside a green circle.You can open the studio by clicking the icon.
Step 11: Click on the button to begin a new project.
It can be found in the window labeled "Welcome to Android Studio".If you don't see a window, check to see if it is hidden by other windows.
Step 12: Click Next to select an activity.
You can choose from a variety of templates when you start a new project.You can choose the devices you want to design for using the tabs at the top.Phone and tablet, WearOS, TV, etc.If you want to learn how to make apps, you should select "Empty Activity".The additional features the other activities provide can be used when you have figured out app programming.
Step 13: You can enter a name for the app.
This is at the top of the "Configure your project" page.You should see what the app is for immediately.
Step 14: The language should be Java.
Below "Language", use the drop-down menu to select.
Step 15: Pick the version you want to design for.
You can use the drop-down menu to choose the earliest version of the app you want to use.Even if it is older, you should choose a version that is supported by most devices.
Step 16: Click to finish.
A new project is created.Allow some time for the automated build system to set up your project.
Step 17: Understand what you want to do
Think about what input the user will give, how you will process it, and how to show the output to them.In this example, the user can enter two numbers and the sum is displayed.
Step 18: You can open the translations editor.
Even if you don't translate the app, it's a good idea to only use strings from the translation resources.Click the tab that says at the top to open the Translations editor.The icon that looks like a globe is next to the drop-down menu that says "Default (en-us)".The option says.
Step 19: Add some words.
You will have to explain to the user what they are supposed to do.To add a string, press on the plus button in the upper left corner of the translation editor.A short key is like a variable name.Next to "Default Value", enter the full English text.You can enter two numbers to add.Click.You can add a locale by using the button that depicts a globe with a + sign on it, and then translate all the text to that locale.
Step 20: You can click on the activity_main.xml tab.
You can close the translation editor and go back to the Activity Main screen.The text "Hello World!" will be displayed on the empty screen.In the middle.This interface is useless for now.
Step 21: "Hello World!" should be replaced.
"The following steps can be used to replace the "Hello World!"The textbox is in the center.The input is labeled "text" on the right side."Hello world!" should be replaced.You can use "@string/main_instruction" or whatever you want.The textbox will now show the text you entered.You have space below the textbox if you drag it further up.Click on the entry of "Text View" in the menu that displays all items and you will be taken to the next page.If the textbox is moved to an unacceptable position, move it back to where it was.To center the textbox, select followed by.
Step 22: There are two inputs on the screen.
Click in the panel to the left below "Palette" to add the inputs.There are two inputs to the preview screen.You can change the IDs by using the text box labeled "Id" in the Attributes panel."number 1 and number 2."Don't use spaces in the Id.You should center the number inputs the same way you did with the textbox.There is a warning about missing an attribute.
Step 23: There is a button on the screen.
Click in the panel to the left below "Palette" to add an "add" button.You can drag on the screen.The translation editor will add a string with the key "text_add" and "Add" as the default value.Go back to "activity_main.xml" and replace the text "Button" with "@string/text_add" in the Attributes panel to the right.You should center the button the same way you did the other objects.
Step 24: There are two translation strings.
Two new strings can be created with the Translation Editor.The key and result should be called "result" and "Result" respectively.The other one should be called "not_yet_calculated" as the key and the default value.
Step 25: Two more textboxes should be added.
Go back to the "Activity_main.xml" tab and add two new text boxes.Below "Palette", click in the panel.There are two text boxes on the screen.You should replace the strings with the ones you added.Textbox should display an ID like "result Out" in the "id" field of the Attributes panel.Limit these textboxes to parent start and parent top.
Step 26: You can switch to "mainActivity.java".
The app code is contained in this file.
Step 27: Determine the necessary variables.
To change the textbox to the result of the calculation, you will need to get the user input.To see the items on the screen, the program needs to see them.They should be declared final because you will never change them directly.You can type the following on the line below the onCreate function.Change the textboxes and buttons if they have different names.There is a possibility that this is not the case.The final code is as follows: final EditText num1, final edit text num2, and final button button add
Step 28: You can create a click listener.
When a user clicks on a button, the function is called.To add one, type the following below the final line of code.
Step 29: Code can be added into the click listener.
You want to get the user's inputs, convert them to integers, add them together, and change the text of the "not calculated yet" textbox to the result.The following code should be added to the "public void onClick(view v)" line.
Step 30: The app needs to be built.
Click the tab to use the following steps.Click on it.
Step 31: You can find the "locate" link in the lower right corner.
The folder will be opened in the file manager.
Step 32: You can connect.
Use the transfer cable to connect your device to your computer.
Step 33: The APK should be copied.
If you want to avoid making a mess on the phone, you should either create a new directory or use the Downloads directory.Don't copy the file, just ignore it.
Step 34: The app can be found on the phone.
The file manager can be opened.If it isn't in the recent downloads, you can search for it.
Step 35: The app is on the phone.
Should you install it?Wait for the installation.To install and test your app on your phone, you have to allow it to be installed from external sources.After installation, you can uninstall the app.If you need it again, you can always build a new one on your computer.
Step 36: The app is on the phone.
A dark blue-green background will be used as an icon.
Step 37: Check to see if the app works as expected.
