What is the right technique to automate Android builds from command line with gradlew command?

Prahlad Yeri — Fri, 14 Jun 2024 15:42:00 GMT

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.

What is the correct syntax to call onCreateOptionsMenu() and onPrepareOptionsMenu() in Android Studio?

priyamtheone — Sat, 02 Mar 2024 15:39:00 GMT

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.

\@Override

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.

\@Override

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.

\@Override

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.

\@Override

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.

\@Override

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?

Beginner question #kotlin #mssql

unEsprit deCendres — Fri, 20 Jan 2023 08:30:00 GMT

Hmmm, it's kind of hard to ask a question because I know something, but only that I don't know much yet 😕.
I want to go back to learning in the project.
Blocks to use: #android , #kotlin , #mssql
Interface in Kotlin already covered (as such ) Database in MS SQL (not the worst, a bit of my hubby ) Connection covered.

And here comes the conundrum of which way to go. Conditions to be met:
1. Work with the database offline/online.
2. When resuming the connection, the client data is synchronized with the server connection test is carried out "independently"
3. data update on the server is done "independently"
4. In offline mode, customer data cannot be lost even after restarting the device

I was thinking of using #sqllite #maven on a device between user and #mssql
Do you know any simple tutorial?
Most of the tutorials I've come across end with "select * from table"; and the rest is up to you. Hurrah 😕

shoutcast upstreaming v1 or v2 from android to server

Ismail ahmed 2022 — Sun, 16 Oct 2022 05:23:00 GMT

I've checked the many blogs and forums and github but nothing found related/help for implementing shoutcast v1 or v2 in android, only ref which is helpful I've found in github is this:

https://github.com/fatihsokmen/android-icecast-broadcast

but above code only work with icecast server and also very limited use and files which is used for broadcasting is *.so files so we can not change or override the exiting methods.

is there any guide or helpful link or source code which I can use to build shoutcast broadcasting in

Passing views to a second fragment screen does not display them correctly

lixo ten — Tue, 27 Sep 2022 03:31:00 GMT

I am getting an an error when I try to display 2 input views. They are captured in one fragment screen and then I try to display them on a second fragment screen. The navigation works but they display as resources?... i do not even know what it is called.

This is the setOnClickListener that calls up that screen. I suspect it has something to go with safeArgs

Kotlin

binding.buttonConfirm.setOnClickListener{
    val username = binding.editTextUsername.toString()
    val password = binding.editTextPassword.toString()
    val action = LoginFragmentDirections.actionLoginFragmentToWelcomeFragment(username, password)     findNavController().navigate(action)
}

I want to program an application to search for contacts by name or phone number use java or kotlin or flutter

Salim Alghiathy — Tue, 31 May 2022 00:32:00 GMT

I have an idea for an app but I'm very confused and don't know where to start I want to program an application to search for contacts by name or phone number use java or kotlin or flutter

The mechanism of its work is when the user installs the application, the contacts are pulled from the phone and then uploaded to an external database. This process is done for all users so that when one of the users tries to search by phone number, it displays all to him from the database the names that are registered in all other users’ phones I ask fellow engineers to help me from where to start and how to program it Thank you from the bottom of my heart

How to create a centralized messaging system?

Hello everyone

I don't really know how to code but i have this project to create a centralized messaging app to concentrate all the messages of my social networks (snapchat, telegram, wattsap...).

I have done some research on API or similar projects but didn't find things that could help me.

If you have any advice on what type of code i will have to learn, idea of similar questions on the forum or documentation it will help.

Thanks

Whats the best way to get others involved in a project app?

Jstavene — Fri, 08 Apr 2022 05:45:00 GMT

I have a idea for a project a app, that I think could be a money maker, but even better I think could save lives and make lives better for many? Huge catch, it would require coding I do not know, and business cooperation but I think I have some contacts to begin. I thought about making it open source and no profit but I think if others want to be paid, I could not afford that, so I am working on making a nondisclosure aggreement, then cut percentages for the app? What interests developers, attracts talent? Is this enough? (looking at some months to mature maybe years) I am thinking I could dump into a nonprofit developer site then there is a hardware component I want to add at some point.

Cristo1985 — Fri, 25 Feb 2022 07:38:00 GMT

Hi,
i need a little help.

I'm creating my custom Drawing View.

The functionality I am trying to achieve is:

Arrow icon => touch one point and drag until other point draws line-arrow

Text icon => touch in one point of screen and enter a text (open keyboard and write and close it)

Eraser icon => erase canvas drawn

These is the design of the menu I've made:

TOOLS MENU

And all interface is here:

I've tried to add this method inside Drawing View class:

Java

public void drawText(String testo)
   {
       mDrawPaint.setColor(Color.WHITE);
       mDrawPaint.setTextSize(200);
       mDrawCanvas.drawText(testo, 10, 25, mDrawPaint);
       invalidate();
   }

But when i call this method can't see add text...

Thanks for any help. Cris
