    The Best Version(s) For Game Development

    Posted: 18 Jul 2021 07:03 AM PDT

    Hello folks.

    I am incredibly new in Android Development. I would like to use Kotlin for development, I don't have much coding experience but love to learn, so it won't bother me.

    Right now, stuck at picking the best Android version for hyper-casual game development. I checked the top charts to see the version of the most popular games, they are in between Android 4.4 - 5 versions.

    Atm, thinking about picking Android 6 or 7. I don't have a specific game in my mind, but I want to experience all the possible advantages of newer versions and use them in my app, in the same time I want to get the best outcome from it (high distribution, more features).

    With Android 7.0, I get Vulkan API for the bonus. But I am not sure how much advantage I will get from it, because I lose approx 10-15% of Android users.

    Waiting for your suggestions and really excited to discuss them. I might make not much sense, but as I said, I am incredibly new and want to learn everything :)

    Thanks, have an awesome day.

    How to pass data between activities that isn't bound to the first activity's view

    Posted: 18 Jul 2021 04:27 PM PDT

    I have this app where I have a recycler view that gets the images and titles of news. Then, when the user clicks on the image, the news is supposed to open and show the image, title and then the author and description of the news. The thing is, the author and the description were not on the recycler view and I want to add them to the second activity that shows the detail of the news. How can I do that since the data isn't bound to any view yet and, therefore, I can't pass it through an intent (I think)?

    This is my recycler adapter with the setOnClickListener that triggers the second activity: ``` package com.example.newsapp

    import android.content.Intent import android.icu.text.CaseMap import android.net.Uri import android.view.LayoutInflater import android.view.View import android.view.ViewGroup import android.widget.AdapterView import android.widget.ImageView import android.widget.TextView import androidx.core.content.ContextCompat.startActivity import androidx.recyclerview.widget.RecyclerView import com.example.newsapp.databinding.NewsItemBinding import com.squareup.picasso.Picasso

    class RecyclerAdapter ( private var Titles: List<String>, private var Images: List<String>, private var Authors: List<String>, private var Descriptions: List<String> ) : RecyclerView.Adapter<RecyclerAdapter.ViewHolder>(){

     inner class ViewHolder( view: View ): RecyclerView.ViewHolder(view){ private val binding = NewsItemBinding.bind(view) val itemTitle: TextView = binding.tvTitle val itemImage: ImageView = binding.ivNewsImage fun bind(urlToImage:String){ Picasso.get().load(urlToImage).into(binding.ivNewsImage) } init { itemImage.setOnClickListener{ val intent = Intent(view.context, PostActivity::class.java) intent.putExtra("title",itemTitle.text) intent.putExtra("source",) view.context.startActivity(intent) } } } override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder { val v = LayoutInflater.from(parent.context).inflate(R.layout.news_item, parent, false) return ViewHolder(v) } override fun onBindViewHolder(holder: ViewHolder, position: Int) { holder.itemTitle.text = Titles[position] val itemImage = Images[position] holder.bind(itemImage) } override fun getItemCount(): Int { return Titles.size }

    } This is the second activity that needs to have the extra details: package com.example.newsapp

    import android.media.Image import android.os.Bundle import android.widget.TextView import androidx.appcompat.app.AppCompatActivity import com.example.newsapp.databinding.ActivityPostBinding

    class PostActivity: AppCompatActivity() {

    private lateinit var binding: ActivityPostBinding override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_post) binding = ActivityPostBinding.inflate(layoutInflater) val view = binding.root setContentView(view) //get title var detailTitle = intent.getStringExtra("title") binding.tvTitleItem.text = detailTitle //get image //get author //get description }

    } This is the API response: package com.example.newsapp

    import com.google.gson.annotations.SerializedName

    data class NewsResponse ( @SerializedName("status") var Status: String, @SerializedName("totalResults") var totalResults: Int, @SerializedName("articles") var Articles: List<ArticlesData> )

    data class ArticlesData ( @SerializedName("source") var Source: SourceData, @SerializedName("author") var Author: String, @SerializedName("title") var Title: String, @SerializedName("description") var Description: String, @SerializedName("url") var Url: String, @SerializedName("urlToImage") var urlToImage: String, @SerializedName("publishedAt") var publishedAt: String, @SerializedName("content") var Content: String )

    data class SourceData ( @SerializedName("name") var Name: String, ) ```

    This is the Main activity: ``` package com.example.newsapp

    import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import android.util.Log import androidx.recyclerview.widget.LinearLayoutManager import com.example.newsapp.databinding.ActivityMainBinding import kotlinx.coroutines.* import retrofit2.Retrofit import retrofit2.converter.gson.GsonConverterFactory import java.lang.Exception

    class MainActivity : AppCompatActivity() {

    private lateinit var binding: ActivityMainBinding private lateinit var adapter: RecyclerAdapter private val newsTitles = mutableListOf<String>() private val newsImages = mutableListOf<String>() private val newsAuthors = mutableListOf<String>() private val newsDescriptions = mutableListOf<String>() override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) binding = ActivityMainBinding.inflate(layoutInflater) setContentView(binding.root) makeAPIRequest() } private fun initRecyclerView() { adapter = RecyclerAdapter( newsTitles, newsImages, newsAuthors, newsDescriptions) binding.rvNews.layoutManager = LinearLayoutManager(this) binding.rvNews.adapter = adapter } private fun addToList(title:String, image:String, author:String, description:String){ newsTitles.add(title) newsImages.add(image) newsAuthors.add(author) newsDescriptions.add(description) } private fun makeAPIRequest() { val api = Retrofit.Builder() .baseUrl("https://newsapi.org/") .addConverterFactory(GsonConverterFactory.create()) .build() .create(APIService::class.java) GlobalScope.launch(Dispatchers.IO){ val response = api.getNews() val posts = response.body() try{ if (posts != null) { for(art in posts.Articles){ Log.i("Main Activity", "Result = $art") addToList(art.Title,art.urlToImage, art.Author, art.Description) } } withContext(Dispatchers.Main){ initRecyclerView() } } catch (e:Exception){ Log.e("Main Activity", e.toString()) } } }

    } ```

    [HELP] Jetpack Compose vs XML For The Absolute Beginners

    Posted: 18 Jul 2021 01:55 PM PDT

    Hey everybody!

    I have a quick question, I am on the way to learning Kotlin and Android, I will soon switch to android and started researching about XML and Compose, I really couldn't like XML( I actually hated it :( ) and loved the Compose which is similar to the Dart/Flutter, but from what I researched that Compose is not stable yet, which is really interesting to me. How the heck this amazing system cannot be stable so far? So my question is, What if I will directly start picking up the "Jetpack Compose" from the very beginning and without touching the XML, would this be a proper way? I mean, Will I encounter some problems with Compose because it is not stable? Please also consider that I will be still a beginner in the next 1 year, maybe Compose will be stable till then? (I hope it will :)

    any help would be appreciated, thanks in advance

    Google Play Console Reviewing

    Posted: 18 Jul 2021 06:02 AM PDT

    I have submitted my game for closed testing and it is under review, and I plan to publish it afterwards. Was just wondering how long these usually take from your past experiences.

    Is gradle configuration avoidance possible with AGP?

    Posted: 18 Jul 2021 05:04 AM PDT

    I tried
    android { applicationVariants.configureEach { variant -> variant.outputs.configureEach { output -> println "variant=${variant.name}" } } }

    I also tried the new variants api in AGP 7

    androidComponents { onVariants(selector().all()) { variant -> println "variant=${variant.name}" } } }

    it still prints when running gradlew help, i.e. being configured

    Why? Or this is as designed and are only the tasks registered this way in the lambdas supposed to be lazy? That would work

    However, then there is apk renaming, where I read git hash, I don't want to pay this configuration price every build, when running unrelated variants

    ``` applicationVariants.configureEach { variant -> variant.outputs.configureEach { output -> if (variant.buildType.name == "debug") return

     // Rename APK def variantName = variant.name def date = new Date().format("dd-MM-yyyy") def versionName = variant.versionName.replace(".", "-") def versionCode = output.versionCode def version = "v${versionName}_${versionCode}" def gitHash = getGitHash() outputFileName = "app_tm__${variantName}_${gitHash}__${date}__${version}.apk" } }

    ```

    (and config cache is broken in ksp)

    UI Design in Android Studio

    Posted: 17 Jul 2021 05:01 PM PDT

    Good afternoon

    I currently use Adobe to design my apps UI and icons before completing the design in Android studio, but I am starting to feel like it is less productive since I am both the developer and designer. Does anybody else only use Android Studio? Since I am fulfilling both roles, would I need to pre-design the UI in Adobe or would it be good practice if I just designed everything within Android Studio?

    Use Python programs for making an app

    Posted: 18 Jul 2021 06:48 AM PDT

    Hello everyone, I assume that I am a beginner in Android development. I have in mind (for educational purposes only) to create an app (or better, a GUI) that would use the youtube-dl software. Is there a way to integrate a Python software (open-source) into an app? The only shortcut I think is to make a REST api instead of integrating everything into the app. Do you have any advice for me?

    What laptop specs would you recommend for android app building?

    Posted: 18 Jul 2021 01:12 AM PDT

    Currently I have intel 8th gen i5 , 8 gb ram and HDD and whenever I am starting android studio,

    my hdd goes to 100% capacity, CPU goes to 80% and ram goes upto 95%.Also, a single page build takes upto 40 mins to build(it's an old laptop).

    Can you recommend what spec should a computer have for faster android build and running smoother emulator? I know that windows 10 pro is important and it has hyper v which is important for intel-HAXM to run (smoother AVD performance).

    What are your experiences with using Appium for your mobile testing? Have you used Appium Studio or do you find it doesn't add any benefit and you can do the same without it?

    AndroidTV images for Mac M1 (compiling them?)

    Posted: 17 Jul 2021 07:55 PM PDT

    I've been able to use the M1 mac to develop on Android for a little while thanks to the native arm64-v8a images for the latest OSes which run on the emulator. Unfortunately no trace of a build for AndroidTV.

    I haven't found any clear instruction on how to compile an image for AndroidTV myself, similar to the official ones (if that's even possible), could anyone point me into the right direction?

    Google's review process when promoting open beta to production

    Posted: 17 Jul 2021 10:07 PM PDT

    Hi guys! Usually, when I promote my app from open beta to production, Google's review takes about 5 minutes. But not this time: they took it on review yesterday, and still no sign of activity from them. Open beta version was review successfully in ~6 hours, but ~8 hours already passed now, after I promoted it, still no sign of any activity.. Too bad, this version only had few minor fixes over previous one, with major changes. And now I even can't do a full rollout of the previous version (its rollout halted automatically) Is this normal? Did this happen to your apps as well? Do you know, if there's any way to check the review status in details or to ask somewhere for speed up?
