I want to build my Android Studio project from command line as opening it consumes too much RAM. Besides, my app is "WebView heavy", most of the work happens in HTML/JS/CSS inside of the webview, so it makes sense to build the APK/AAB directly from command line for testing. So far, I'm able to generate bunlde with the below command after setting the JAVA_HOME to \path\to\android-studio\jre\jre
gradlew bundle
However, this generates only the bundle file (*.aab) and that too the unsigned or debug version. What I want to generate is:
- Signed *.aab to release on Play Store.
- Unsigned *.apk for testing.
When I list the tasks using gradlew tasks command, it gives me the below. What should I do to achieve these objectives? I already tried some other tasks (build and assemble) as parameters but they result in error.
EDIT: OK, found some helpful information here. The second one (debug APK) I managed with the assembleDebug task. The first one (signing the aab) is still a constraint.

In Android Studio, I came across different ways to implement onCreateOptionsMenu() and onPrepareOptionsMenu() each with respect to the return statement in an Activity that extends from AppCompatActivity. It is quite confusing to me as to which one is the right way to implement the two methods, given that I want to maintain equality of syntax all across my application.
onCreateOptionsMenu()
Example 1: Only true is returned.
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
}
Example 2: Call to super class is returned.
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.options_menu_activity_dashboard, menu);
return super.onCreateOptionsMenu(menu);
}
Example 3: Call to super class is done in the first line and true is returned later.
public boolean onCreateOptionsMenu(Menu menu){
super.onCreateOptionsMenu(menu);
Intent intent = new Intent(null, dataUri);
intent.addCategory(Intent.CATEGORY_ALTERNATIVE);
menu.addIntentOptions(
R.id.intent_group,
0,
0,
this.getComponentName(),
null,
intent,
0,
null);
return true;
}
As you see, in the third example, call to super class is done followed by returning true. But in the first two examples, either true or call to super class is returned. Which one is the right way to do it?
onPrepareOptionsMenu()
Example 1: Call to super class is returned.
public boolean onPrepareOptionsMenu(Menu menu) {
if (Build.VERSION.SDK_INT > 11) {
invalidateOptionsMenu();
menu.findItem(R.id.option2).setVisible(false);
menu.findItem(R.id.option4).setVisible(true);
}
return super.onPrepareOptionsMenu(menu);
}
Example 2: Call to super class is done in the first line and true is returned later.
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
menu.findItem(R.id.action_save).setVisible(true);
menu.findItem(R.id.action_reset).setVisible(true);
menu.findItem(R.id.action_about).setVisible(true);
return true;
}
Here too the same question arises. Which syntax should I follow to implement the method properly?
|
|
|
|
|
Why not call the super class method first, and if it returns false, bail early?
Eg:
public boolean onPrepareOptionsMenu(Menu menu) {
if (!super.onPrepareOptionsMenu(menu))
{
return false;
}
menu.findItem(R.id.action_save).setVisible(true);
menu.findItem(R.id.action_reset).setVisible(true);
menu.findItem(R.id.action_about).setVisible(true);
return true;
}

Thanks for your suggestion. I'll keep that approach in mind for future reference. However, I found a better way to deal with the situation. Unless my code relies on a superclass's implementation, returning true after my modifications is straightforward. If I ever extend a class and want to allow the superclass's logic to still apply, I'll use the super call then. That seems to be the optimal approach.

Nobody is going to send you a personal email on this. The conversation either happens in the forum or it doesn't happen at all.
Oh, and posting your email address in a public forum only invites spammers to flood your inbox.

Hi guys, i want to know, can you guys tell me what I need to learn to create a simple web application for ecommerce website (not a complicated marketplace app) like for example: "shoes website" with the abilities for customers to sign up and put the product into shopping cart and then check out with simple payment system like paypal?
|
|
|
|
|
I am not sure why you posted this in the Android forum.
However, you need to study ASP.NET or PHP for the backend, HTML, CSS and Javascript for the frontend, and a suitable Database system. You can also Google for ecommerce to see if there are templated systems available to get you started.
|
|
|
|
|
can this ecommerce website be transformed into or opened as android app as well?
|
|
|
|
|
Possibly, but this is not something you can achieve in an afternoon. The question again requires considerable research.
|
|
|
|
|
Anyway, last question. What is the suitable database system for this ecommerce website that can store customers accounts and then send their order to us as well as payment confirmation when they have made the payment?
Thanks for your answers. really helped a lot with your answers. I have learned HTML, css and currently working on JavaScript. Anyway, do i need to learn about Typescript and React as well as Im building this web ecommerce website for android app as well?
|
|
|
|
|
The most common database systems are MySQL and Microsoft SQL Server. But you would need to study both to decide which is best for you. I do not know whether Typescript and React would be necessary or not, but their respective websites would probably give some ideas.

What you described is not simple.
Simple would be just to get a web server up and responding to a request.
Ben A Johnson wrote: what I need to learn
1. Do you know a normal programming language? Java, C# and/or C/C++. But JavaScript might also work (but NOT using it only in a web page.)
2. Database. Doesn't matter which one. You don't actually need to learn a relational one (SQL) but I consider those more useful, but more difficult, to learn.
3. Basics of Web Servers: Server, Client, other misc stuff, like how IP works.
4. After you learn most of that then you need to get a basic web server up which usually requires some sort of 'web server'. Which one depends on what you learned above.
5. Then you need to learn how to deliver content to a Client. So for example how a browser sends a request then gets a response.
After all of that then you could start, if that is your real goal (this forum) learning how to create a cell phone application. Such as one that runs on an Android phone. There are examples out there that would allow you to start from this step but it might not help if you do not understand at least some of the above.

Thank you so much for all of your answers man. Really helpful a lot. Yes, I'm still learning about JavaScript and I have been doing some research on YouTube regarding how to build an ecommerce website/app using MySQL PHP. But I want to ask. So i saw a video where this guy create an ecommerce site (clothing site) with the abilities for customers to sign up and then edit their profile (shippinng address, avatar, phone number, so on), and the admin is also able to edit any product that he sells through the admin page of his site. What i want to ask is, when he opens his admin page (where he can edit all of his products, verify payment, verify whether the product has been shipped or not, etc) is that ADMIN PAGE MySQL? How did he create that admin page? Did he build it from a scratch? I'm sorry for asking this, but I still want to get a better understanding about how this ecommerce site works?

There is nothing special about that page versus other pages. Any page does what the page does. Only difference there is that the page (and supporting backend functionality) was written to do that.
Basic outline of functionality for a page
browser => front end => business logic (of some sort) => database layer (of some sort) => database
Everything else is in the the details.
Since you mentioned PHP and MySQL you could look at LAMP. However I am not sure that is a good route for you to take at your experience level. But there might be some better tutorials now (versus very long ago when I looked to help.) If you go down that route then use Python rather than PHP since it is more widely used thus knowledge of it is more beneficial.

Hi I was just seeing a video on YOuTube explaining about MySQL and how it works with localhost XAMPP especially to create the database of data like products, customers, etc. What I want to know, Can I just learn about MySQL, HTML, CSS and JavaScript to make a fully working ecommerce website? And if I want to make an Android app of that ecommerce website, what else do I need to learn? Do i need to learn about React, Python and Java too (with Android studio)?

Not quite, as you need backend code to act as the interface between the web pages and the database. So you will need C#/VB.NET or PHP for that part. As to the Android system, you need to study some articles on Android development.
|
|
|
|

Thanks for your reply. Yes, I just saw a video explaining about the connection between HTML page, PHP and MySQL database? And how the login password or how user can register an account and then connect their data using PHP to our MySQL database using XAMPP. I wanna ask again. About MySQL. After we finish creating our database from user information, our products, etc using MySQL, do we need to upload these database (including our website with HTML, css and JavaScript) from our localhost (XAMPP) to our web hosting/server so the who ecommerce site can start operating?
|
|
|
|

You can host your database anywhere you like, although the logical place is on the webserver. And you would use that live database for all your account creation, i.e. users register on the site and then use their id and password for future logins.
But, TBH, you seem to be trying to run before you can walk. You should start small and get a basic website working, with a simple front end page and a simple text file rather than a database at the back end. That would help you to understand some of the issues that need to be worked on. The internet, and indeed Web Development[^] here on CodeProject, has many articles and samples that will help you.

As said before and just with the last post...
You cannot understand the big picture until you have at least some familiarity with some of the various parts. You need to pick a part and start learning just that part.

I received the following message from you, but it does not appear in the forum here (maybe you deleted it):
Quote: Thanks man for your reply. Yes you are right. I think i need to build simple website project for ecommerce first before jumping to the more difficult parts. I wanna ask by the way, so i found these 2 cool websites: Netlify and then 000webhost. And these 2 sites offers free web hosting for web projects and also Database with phpmySQL, and you can add your own domain there. what do you think about these 2 sites, are they legit and can be trusted for our professional web projects like serious ecommerce sites.
I cannot say whether either of those site will help you as I have no experience of them. However, as I and @jschell keep saying, you need to start with something simple. Forget about ecommerce as you are nowhere near ready to implement such a system. Just create a simple website that allows you to enter some data that can be checked by the backend. If necessary the backend can write it to a file so you can do some manual checking. You could host such a system on your own PC using IIS, which is part of Windows. I have such a system on my PC and it works fine as a test bed.

I've been developing Android apps since around 2009 and don't even think I'd try tackling an eCommerce project. Now sending data to a database backend from an Android device...way easier.

I agree, and have done both on a very small scale. I don't think the OP fully understands the issues involved, despite me and @jschell trying to point out some of the things that need to be understood.
