QUESTION

There was a problem saving the text in EditText to a file

Asked 2021-Jun-16 at 01:47

This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.

And manifest.

uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

is written.

Please let me know the solution. And this content is written with a translator, so the sentence can be strange.

when you press finButton, the logcat is shown below.

The code corresponding to the 116th line is this.

FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

Upgrade your dagger-hilt dependencies to the same version.

How does Kotlin coroutines manage to schedule all coroutines on the main thread without block it?

Asked 2021-Jun-15 at 14:51

I've been experimenting with the Kotlin coroutines in android. I used the following code trying to understand the behavior of it:

fun onStartButtonPressed(view: View) {
    Log.d(TAG, "Outside Scope: ${Thread.currentThread().id}")

    lifecycle.coroutineScope.launch {
        Log.d(TAG, "Top Level Scope: ${Thread.currentThread().id}")

        val t1 = launch {
            Log.d(TAG, "Task 1 Scope: ${Thread.currentThread().id}")
            for (i in 1..2) {
                delay(1000L)
                withContext(Dispatchers.Main) {
                    viewBinding.task1ProgressBar.progress = i * 50
                }
            }
        }

        val t2 = launch {
            Log.d(TAG, "Task 2 Scope: ${Thread.currentThread().id}")
            for (i in 1..4) {
                delay(1000L)
                withContext(Dispatchers.Main) {
                    viewBinding.task2ProgressBar.progress = i * 25
                }
            }
        }

        t1.join()
        t2.join()

        withContext(Dispatchers.Main) {
            Log.d(TAG, "Completion Scope: ${Thread.currentThread().id}")
            viewBinding.startButton.isEnabled = true
            viewBinding.resetButton.isEnabled = true
            viewBinding.statusTextView.text = "All tasks have been finished."
        }
    }

    viewBinding.statusTextView.text = "All tasks have been started."
    viewBinding.startButton.isEnabled = false
    viewBinding.resetButton.isEnabled = false
}

This is very wired to me as join() method would block the main thread but the UI is not freezing, why is that?

This is exactly the reason why coroutines were invented and how they differ from threaded concurrency. Coroutines don't block, but suspend (well, they can do both). And "suspend" isn't just another name for "block". When they suspend (e.g. by invoking join()), they effectively free the thread that runs them, so it can do something else somewhere else. And yes, it sounds like something that is technically impossible, because we are in the middle of executing the code of some function and we have to wait there, but well... welcome to coroutines :-)

You can think of it as the function is being cut into two parts: before join() and after it. First part schedules the background operation and immediately returns. When background operation finishes, it schedules the second part on the main thread. This is not how coroutines works internally (functions aren't really cut, they create continuations), but this is how you can easily imagine them working if you are familiar with executors or event loops.

delay() is also a suspending function, so it frees the thread running it and schedules execution of the code below it after a specified duration.

QUESTION

How can add a Row dynamically in flutter?

Asked 2021-Jun-15 at 14:50

My problem is that, I have a List of Icons(CustomWidgets) what are provide by an API. I need put this icons in my App but when the are 7 or more its looks like these:

I want to put the icons in separate rows. I've tried out a method which split the list in 2 and add it dynamically but didn't print anything because I'm using a FutureBuilder to print the Icons.

Here is the code:

FutureBuilder(
            future: investCall, //API CALL
            initialData: [], //NULL SAFE
            builder: (context, snapshot) {
              if (snapshot.hasData){
                return investCodes();
              }else {
                return Divider();
              }
            }, //BARRA DE REDES SOCIALES
          ),

Method investCodes(); Where I added the icons

Widget investCodes(){
List<Widget> iconos= []; //EMPTY ICON LIST
for (var object in _investCodes){
  //print('Pintando: '+sn.accesto); DEBUG CONSOLE
  iconos.add(
          Flexible(
          flex: 1,
          child: Container(
            child: GestureDetector(
              onLongPress: (){
                /*...*/
              },
              //JAVA ANDROID ONCLICK LISTENER
              onTap: (){
                _launchURL(object.rfUrl);
              },
              child: Center(
                child: Container(
                  padding: EdgeInsets.only(left: 2.0.h, right: 2.0.h),
                  height: 3.0.h,
                  child: FadeInImage(
                    image: NetworkImage(object.rfIconUrl),
                    placeholder: AssetImage('assets/sn-placeholder.png'),
                  ),
                ),
              ),
            ),
          ),
      )
  );
}


  return Container(
      /*HERE I WANT TO ADD A COLUMN WITH MULTIPLE ROWS*/
      padding: EdgeInsets.all(18.0),
      width: 100.0.w,
      child: Row(
        children: iconos, //LIST OF ICONS
      )
  );
}

What I suggest is to use Wrap instead of Row in your case, widget will place in the 2nd row is not enough space

THERE IS THE WAY TO DO IT:

      return Container(
      padding: EdgeInsets.all(16.0),
      width: 100.0.w,
        child: Center(
          child: Wrap(
            spacing: 10.0,
            runSpacing: 10.0,
            direction: Axis.horizontal,
            crossAxisAlignment: WrapCrossAlignment.center,
            children:iconos, //LIST OF ITEMS
          ),
        ),
  );
