I have textfield that I am setting text string and observing strange issue If the string is "🙏" which is codepoints 128591 1f64f I see the first image, But if the string is "🙏🙏" which is basically 2 code points with values 128591 128591, I see the second image Is there something special I need to do in order for the first emoji to get rendered correctly in a textView? The emoji in question is - https://www.unicodepedia.com/unicode/emoticons/1f64f/person-with-folded-hands/

Any way to make an object such as a sound start on background without a button on Android studio? I can make it as a button to start but haven't found resources to make it start automatically as the activity starts . Would really appreciate the help. Using kotlin language that is

Is it a good idea to pass an intent to a viewModel ?

Are there any tutorials on how to sideload Baseline Profiles besides the official docs? They explain it pretty poorly

Trying to get my head around Views & Widgets. Am I correct in thinking widgets are a type of 'bottom level' Views (i.e. Buttons, TextView...) that do not contains Views.

OK sorry me again, with some not great code from a course (they are slowly sorting out code to show problems and how to make it better).

override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
    Log.d(TAG, "getView called pos $position")

    // if convertView is null inflate it otherwise use it
    val view =
        if (convertView == null) {
            Log.d(TAG,"getView called with null convertView")
            inflater.inflate(resource, parent, false)
        } else {
            Log.d(TAG,"getView privided a convertView")
            convertView
        }

    val tvName: TextView = view.findViewById(R.id.tvName)
    val tvArtist: TextView = view.findViewById(R.id.tvArtist)
    val tvSummary: TextView = view.findViewById(R.id.tvSummary)

    val currentApp = applications[position] // position from constructor

    tvName.text = currentApp.name
    tvArtist.text = currentApp.artist
    tvSummary.text = currentApp.summary

    return view
}

Its the 'val view =' bit I have a question about. I get what it is doing, i.e. only running the inflator if needed. What I don't get is why when the method is run again convertView is set. i.e. when is convertView set to view?

I have a very tricky question that nobody was able to answer it so far. My app needs to create and save a JSON file in the external storage. When I uninstall the app and install it again, I want to click a button that opens a file picker and pick the JSON file I have created before. Is that possible?

You can save your file in external storage. If you store in external storage than user can see or open file using file manager.

Hi all check this article on optimising recycler item inflation by using prefetch view pool https://tech.winzogames.com/optimizing-recyclerview-pre-inflated-viewpool-eaf5a6dd242a

Hello all ! I'm working on android project where I'm doing background task or say tracking location, putting application on background. Now let say my application get destroyed after 3-4 hours due to any reason (most probably OS) I'm tracking my device outages(Active , inactive , app is not reachable) on my backend, so is there any way to trigger some kind of dialogue or wake my application up after get destroyed automatically (so I get location updates properly). hopefully I described my case. I will appreciate your approaches.

Hey, everyone! Just a quick question, does anyone has experience with integrating Ionic Portals into an Android app? I am interested in how does it affect the code quality and development process. Any input would be really appreciated!

Hey, n our app we have SIP module (pjsua2), which has the JNI libs libc++_shared, libpjsua2 • When we try to integrate Zoom SDK(mobilertc and commonlib) we are getting compile exception saying _2 files found with path ‘lib/arm64-v8a/libc++_shared.so’ from inputs:_ _- pjsua2/build/intermediates/library_jni/debug/jni/arm64-v8a/libc++_shared.so_ _- /mobilertc/build/.transforms/445b8adf65ed1845334c5eaf41712982/transformed/jetified-mobilertc/jni/arm64-v8a/libc++_shared.so_ I tried to use packageOptions pickfirst like below to resolve this

android{
  packagingOptions {
      pickFirst 'lib/x86/libc++_shared.so'
      pickFirst 'lib/x86_64/libc++_shared.so'
      pickFirst 'lib/armeabi-v7a/libc++_shared.so'
      pickFirst 'lib/arm64-v8a/libc++_shared.so'
  }
}

The compinlation issue is resolved but when I invoke Zoom API not able find _/libc++_shared.so_

help is appreciated

Hey guys, is there a similar slack/discord channel like this one but for general android questions? I really love this slack but as soon as I have a question about something that has nothing to do with Kotlin for example Baseline Profiles, ART, gradle etc. I don’t know where to post my questions. My questions on StackOverFlow mostly remain unanswered.

Hi, can anyone give me some advice? As part of my learning I decided to create a simple application working with the openWeather API. But I ran into a problem regarding the request.

val url = "<https://api.openweathermap.org/data/2.5/forecast/daily?q=hamburg,de&appid=33aa634c216259f797f35e862f07****>"
val resultJson = URL(url).readText()
Log.d("Weather Report", resultJson)
val jsonObj = JSONObject(resultJson)
val main = jsonObj.getJSONObject("main")

Attempting to execute then brings up the following: https://pastebin.com/84EDhwyU The debug basically did not detect any faults. Anyway, the bug refers this line:

val resultJson = URL(url).readText()

Edit: I will add that when I played with it yesterday I somehow mysteriously managed to get the resulting JSON, but only once and without any code modification. It's as if each time the resulting JSON was loaded incorrectly

you can add the directory as a standard directory, create the

src

directory and add your gradle file. Then in the

settings.gradle

file add the new module as

include ':ui:my-module'

Which kind of Button are you importing?

Hi all, any one try generate coverage inline documentation using dokka

Hi all, I would like to start learning Kotlin programming language, i want to start from scratch. Please send me links and documentations to get started. Thanks.

Hello friends, I just started learning Kotlin. I would be grateful for good advice or a joint project.

do you run

on debug or release build type and why?

Hello everyone, I have a problem doing a startActivity to an Activity that is in another module of the application. I have this error. Maybe it has happened to someone else and they can help me

android.content.ActivityNotFoundException: Unable to find explicit activity class {package/packgae.OtherActivityInFeatureModule}; have you declared this activity in your AndroidManifest.xml?

I was seeing that it is added in the manifest-merge but I still have the error I am creating the intent like this

fun intentToClear(intentActivity: IntentActivity, bundle: Bundle? = null): Intent {
    val intent = Intent(Intent.ACTION_VIEW).setClassName(PACKAGE_NAME, intentActivity.className)
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_NEW_TASK)
    bundle?.let {
        intent.putExtras(it)
    }
    return intent
}

Can we do constructor injection in serivice class

class MyFirebaseMessagingService @Inject constructor(private val repository : Repository) :
    FirebaseMessagingService() {

Hi, I need help with this error:

Unable to create converter for retrofit2.Call<com.marsuch.weatherapp.network.WeatherInfo>

for method WeatherApiService.getWeatherData

I have found a number of different solutions on the internet however none of them work for me. I use Moshi with retrofit. My WeatherInfo.kt

data class WeatherInfo (
    val city : City,
    val cod : Int,
    val message : String,
    val cnt : Int,
    //val list : List<Weather>,
    )

data class City (
    val id : Int,
    val name : String,
    //val coord : Coord,
    val country : String,
    val population : Int,
    val timezone: String?
    )

WeatherApiServices.kt

import com.squareup.moshi.Moshi
import com.squareup.moshi.kotlin.reflect.KotlinJsonAdapterFactory
import retrofit2.Call
import retrofit2.Retrofit
import retrofit2.converter.moshi.MoshiConverterFactory
import retrofit2.http.GET
import retrofit2.http.Query

private const val BASE_URL = "<http://api.openweathermap.org/data/2.5/>"
private var lon: String = ""
private var lat: String = ""
private var appId: String = ""

private val moshi = Moshi.Builder()
    .add(KotlinJsonAdapterFactory())
    .build()

private val retrofit = Retrofit.Builder()
    .addConverterFactory(MoshiConverterFactory.create(moshi))
    .baseUrl(BASE_URL)
    .build()

interface WeatherApiService {
    @GET("forecast/daily")
    suspend fun getWeatherData(
        @Query("lat") lat : String,
        @Query("lon") lon : String,
        @Query("appid") apiKey : String
    ): Call<WeatherInfo>
}

object WeatherApi{
    val retrofitService : WeatherApiService by lazy {
        retrofit.create(WeatherApiService::class.java)
    }
}

The resulting data are displayed as follows:

private val _status = MutableLiveData<String>()    

fun getData() {
        viewModelScope.launch {
            try {
                val listResult = WeatherApi.retrofitService.getWeatherData(lat, lon, api)
                //_status.value = "Success ${listResult} wether data retrieved"
                Log.d("Response weather:", listResult.toString())
            }
            catch (e: Exception) {
                _status.value = "Failure: ${e.message}"
                Log.e("Failure", e.message.toString())
            }
        }
    }

I'm still learning, so I apologize if the solution to the error is trivial.

is there a sight to look up jetpack compose api

reference?

I can test my app on a mobile phone but cant get emulator working. Ive tried emulators using SDK 17, 26 & 29 but it always hands when it get to

var data = URL(params[0]).readText()

it hangs(I used a debugger and when it runs the code it just never comes back, the code is in AsyncTask.doInBackground (I know it depreciated, I am doing tutorials). Any advice? The URL is

<https://www.flickr.com/services/feeds/photos_public.gne?tags=android,%20oreo&tagmode=any&format=json&nojsoncallback=1>

This works fine if I just do it in InteliJ. I know URL is Java but the readText extension is. if it's not enough Kotlinly can someone point me to a good alternative place to ask question?

For an Android dev like me who has been doing traditional Android/Java programming and is new to Kotlin looking into implementing a KMM lib common to both our Android and iOS apps, what would be the best place to start learning Kotlin (and eventually KMM)? Would that be the official Android Kotlin docs or is there a good tutorial series somewhere like Youtube that provides a good crash course on Kotlin (and KMM too)? TIA!
