    Error generating Android app with Cordova Plugin - "Duplicate class com.google.gson...."

    Posted: 13 Jun 2022 07:57 AM PDT

    Hello everyone,

    I'm trying to generate an Android app which uses a Cordova Plugin, and I've tried everything and couldn't manage to solve the following error:

    Execution failed for task ':app:checkDebugDuplicateClasses'. [2022-06-13T14:48:03.937Z] [VERBOSE] [Build] > A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable [2022-06-13T14:48:03.938Z] [VERBOSE] [Build] > Duplicate class com.google.gson.DefaultDateTypeAdapter found in modules jetified-gson-2.6.2 (com.google.code.gson:gson:2.6.2) and jetified-mposSDKRelease-runtime (:mposSDKRelease:) [2022-06-13T14:48:03.938Z] [VERBOSE] [Build] Duplicate class com.google.gson.ExclusionStrategy found in modules jetified-gson-2.6.2 (com.google.code.gson:gson:2.6.2) and jetified-mposSDKRelease-runtime (:mposSDKRelease:) [2022-06-13T14:48:03.938Z] [VERBOSE] [Build] Duplicate class com.google.gson.FieldAttributes found in modules jetified-gson-2.6.2 (com.google.code.gson:gson:2.6.2) and jetified-mposSDKRelease-runtime (:mposSDKRelease:) [2022-06-13T14:48:03.938Z] [VERBOSE] [Build] Duplicate class com.google.gson.FieldNamingPolicy found in modules jetified-gson-2.6.2 (com.google.code.gson:gson:2.6.2) and jetified-mposSDKRelease-runtime (:mposSDKRelease:)

    The list goes on with similar logs.

    Does anyone know what I should do to fix these errors? I have the 'build.gradle', 'build-extras.gradle' and 'gradle.properties' files.

    Creating Android app which can record video at 120FPS.

    Posted: 13 Jun 2022 07:50 AM PDT

    Hi Everyone,

    I'm looking to create an Android app which can use the some specific features of the camera, e.g., recoding a video at 120FPS. Is there a react-native library which can do that? I tried using 'react-native-vision-camera' but that shows support only for 60FPS and not 120FPS. I have a pixel 4a and I know it supports 120FPS. Any suggestions would be really helpful.

    ​

    Thanks for your time!

    Any advice on how to structure Compose functions in an activity/fragment?

    Posted: 13 Jun 2022 03:36 AM PDT

    Compose is making my Activity massive. I would put them in a separate class but my clickable scopes are generally dependent on ViewModel. I am not sure if I should expose the viewModel to a non-lifecycle class.

    But the amount of compose functions needed to build the UI of the screen is affecting the readability.

    Any advice?

    Can I enable static local IPv4 on Android 12?

    Posted: 13 Jun 2022 07:19 AM PDT

    I don't have home internet service, and instead use my phone's wireless tethering to provide access to my devices. I usually get around ~100mbit so it's been fine.

    I use an app called "Every Proxy" to create a HTTPS/SOCKS5 proxy on my Android device. I then connect to this proxy on my machines (Android TV, Windows, Mac etc). This redirects the traffic through my phone, and effectively bypasses tethering limits.

    This works great. The "problem" is that, since Android 12, the local IP on Android devices is no longer static. It used to always be 192.168.43.1. Now, everytime the device is rebooted, it changes local IPv4s, meaning I have to update the proxy settings among all my devices. This is a minor annoyance, but I'd like to find a way around it if possible.

    Note: This began occurring on my Note 20 Ultra after updating to Android 12, and continues on my S22 Ultra. The problem could actually be OneUI/Samsung's Android 12 distro. I don't know, as I don't have any other Android 12 devices.

    Thanks for the assistance.

    Why are browsers allowed to use query_all_apps permission?

    Posted: 13 Jun 2022 03:30 AM PDT

    Ola!

    I would like to understand why browsers are one of the types of apps that are allowed to keep using the permission after Googles update to their policy. Why would a browser make use of that permission?

    The Infor article just mentions "awareness of interoperability". But what would be a concrete example that applies to every browser app?

    Does anyone use Google Pay as payment gateway for their app?

    Posted: 13 Jun 2022 04:08 AM PDT

    Hi, I want to try Google Pay for one of my project and I have a several question regarding the use of Google Pay.

    1. Where can you create/setup your UPI?
    2. What country it can support (Android)? Google Pay in iOS said to only support US and India. I check this page but it doesn't mention any countries.
    3. What are the main limitation of using this service?
    4. What sort of security should be perform when using it? Like protecting the UPI information?
    5. Where can you track all the transaction?

    If you know any blog or tutorial that can help would be very appreciated. Thank you in advance.

    Is using Lua to make an app for Android still possible?

    Posted: 12 Jun 2022 04:37 AM PDT

    I recently heard about someone using Lua for Android development. I try searching out, just to learn about it.

    I found this library, but fail to get it to compile on my machine https://github.com/qtiuto/lua-for-android
    I also found this https://github.com/kigkrazy/luaj-android, but also fail to get it compiled. Seems like it is not supported on the latest Gradle 7.x

    Does anyone know if it is still possible to use Lua to make an Android App? (using the latest Android Studio Chipmunk)

    anyone know what this weird optomization app is for ?

    anyone had a "error: package R does not exist" before? I can't get this to go

    Posted: 12 Jun 2022 04:21 PM PDT

    Since adding an Assets folder to my project I now get:

    error: package R does not exist "return new ActionOnlyNavDirections(R.id.action_newAlarmFragment_to_homeFragment);"

    which is from this auto generated code:

    import androidx.annotation.NonNull; import androidx.navigation.ActionOnlyNavDirections; import androidx.navigation.NavDirections; public class SetNewAlarmFragmentDirections { private SetNewAlarmFragmentDirections() { } @NonNull public static NavDirections actionNewAlarmFragmentToHomeFragment() { return new ActionOnlyNavDirections(R.id.action_newAlarmFragment_to_homeFragment); } }

    I have tried cleaning and rebuilding the project and tried "Invalidate caches and restart". Removing the assests folder does nothing, so it might not even be the assets folder and commenting out the nav code like below also does nothing.

    Looking through other answered questions here it seems it can be an import of R. somewhere causing this, but I can't find anything..

    The NavDirection itself comes from this fragment and three others that are basically doing the same in terms of navigation:

    import android.os.Bundle import android.view.LayoutInflater import android.view.View import android.view.ViewGroup import android.widget.CompoundButton import androidx.fragment.app.Fragment import androidx.lifecycle.ViewModelProvider import androidx.navigation.Navigation import com.pleavinseven.alarmclockproject.alarmmanager.AlarmManager import com.pleavinseven.alarmclockproject.data.model.Alarm import com.pleavinseven.alarmclockproject.data.viewmodel.AlarmViewModel import com.pleavinseven.alarmclockproject.databinding.FragmentSetNewAlarmBinding import com.pleavinseven.alarmclockproject.util.TimePickerUtil import java.util.* class SetNewAlarmFragment : Fragment() { private val timePickerUtil = TimePickerUtil() lateinit var binding: FragmentSetNewAlarmBinding private lateinit var alarmViewModel: AlarmViewModel override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View { binding = FragmentSetNewAlarmBinding.inflate(inflater, container, false) binding.fragmentCreateAlarmRecurring.setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener { _, isChecked -> if (isChecked) { binding.fragmentCreateAlarmRecurring.visibility = View.VISIBLE } else { binding.fragmentCreateAlarmRecurring.visibility = View.GONE } }) alarmViewModel = ViewModelProvider(this)[AlarmViewModel::class.java] // binding.fragmentBtnSetAlarm.setOnClickListener(View.OnClickListener { _ -> // scheduleAlarm() // Navigation.findNavController(requireView()) // .navigate(SetNewAlarmFragmentDirections.actionNewAlarmFragmentToHomeFragment()) // }) return binding.root }

    Fresh Android intern, how should I approach large codebase for enterprise apps? Grant me you guidance r/Androiddev :)

    Posted: 12 Jun 2022 09:44 AM PDT

    tl;dr Got accepted in an internship and I'm given a few days to dive into the codebase until I'm given tasks, what to do?

    Their app is big, not gigantic big and certainly grokkable, about 25-30 fragments, split into 5 modules, is a payment system app so there's a lot to do with keys, encryption, security, etc (things I literally know nothing about but I'm very excited to start researching them).

    So far I've been stuffing the app with log statements on Main Activity and the initial Fragment on almost all of their methods so that I can grok the app's workflow, what calls what and when, and will work my way to the other Fragments with logs. Am I on the right track? What else should I do?

    For people who were in my position and were initially anxious about an intimidatingly large codebase at your first/new work, how did you get through it?

    A question related to Facebook and Android Media Playback.....!

    Posted: 12 Jun 2022 01:16 PM PDT

    Just out my curiosity - For a long time while watching videos on Facebook i have noticed it can automatically pause my own device background music Playback. What bugging me is that why can it resume the playback after the video i was watching is finished or i moved on to watching something else?!!! Like i can play whatever i like in background while surfing right? Why does Facebook have the knowledge of if I'm playing anything or not and not only that it can control it?!!

    is firebase cloud storage a good choice for an video based app?

    Posted: 12 Jun 2022 01:50 PM PDT

    I've been using firebase cloud storage for a long time, but up until now I only needed to store images and zip files. But now there is a new demand to create a video based platform, where users can post and see video of other users (mainly short videos), but I never worked with this type of content on firebase, so I don't know if the price is good or bad...even the cloud storage calculator doesn't show this (only shows about images). So, anyone knows if firebase cloud storage is a good service for this new platform or is it to expensive when it comes to videos? Also, if you know any other services for this, I would appreciate.
