Android Fundamentals in Kotlin Starter Apps

This repository contains the starter code for the apps for the Android Fundamentals in Kotlin course, published by the Google Developer Training Team. See Android Training.

A starter app” is an app that contains the code for starting a codelab.

Code for the solution apps in this course are in a different repository.

Introduction

Each of the samples in this repository is associated with a codelab exercise from the Android Fundamentals in Kotlin course.

The Android Fundamentals in Kotlin course can be used for self-study, or as the basis of an instructor-led training. It is targeted towards beginning Android developers with a background in software development or computer science with at least two years of experience with a modern, object-oriented programming language, such as the Java programming language, and familiarity with basic software architecture principles.

Since this course is in Kotlin, it is assumed you know Kotlin at the level taught in the Udacity course, Kotlin Bootcamp for Programmers.

Pre-requisites

The samples, along with the course, assume basic competence in software design and development, as well as some background in computer science.

Specifically, to get started you need:

Familiarity with the general software development process for object-oriented applications using an IDE (Integrated Development Environment).
At least 1-3 years of experience with object-oriented programming and the Java programming language, or a comparable modern language.
Familiarity with the Kotlin programming language.

Android Studio Version

During development of this course, all samples were built using Android Studio 3.3, and the codelabs assume you are using Android Studio 3.3 with corresponding libraries and available features. See the Android Studio download page for details.

Getting Started

Install Android Studio, if you don't already have it. (If you are just starting the course, you will be guided through this process.)
Download the starter sample for the codelab.
Open the sample into Android Studio.
Build and run the sample. You may need to update gradle and library versions. Follow the guidance provided by Android Studio.

android-kotlin-fundamentals-starter-apps's Issues

GDGFinder app has `drawer_view.xml` with conflict symbols

git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/Documentation/SubmittingPatches?id=4e8a2372f9255a1464ef488ed925455f53fbdaa1

Missed Migration to androidx for Navigation Component.

For GDGFinder-Starter

GIVEN IN THE CODE:

//app  build.gradle file:
version_navigation = "1.0.0"
classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:$version_navigation"


//module  build.gradle file:
implementation "android.arch.navigation:navigation-fragment-ktx:$version_navigation"
implementation "android.arch.navigation:navigation-ui-ktx:$version_navigation"

CORRECTION:

//app  build.gradle
version_navigation = "2.3.0"
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$$version_navigation"

//module  build.gradle file:
implementation "androidx.navigation:navigation-fragment-ktx:$version_navigation" 
implementation "androidx.navigation:navigation-ui-ktx:$version_navigation"

The given code compiled correctly but led to an error on one of my devices (Samsung Galaxy TAB S6 SM-T865, Android 10 - API 29 ) while it worked on other devices.

ERROR:
navAndXError.txt

ViewModelProviders

As stated here : https://developer.android.com/reference/androidx/lifecycle/ViewModelProviders
The ViewModelProviders class is deprecated.
Instead of viewModel = ViewModelProviders.of(this).get(GameViewModel::class.java) you should use
val provider = ViewModelProvider(this, ViewModelProvider.NewInstanceFactory()
viewModel = provider.get(GameViewModel::class.java

MarsRealEstate-Starter does not build

Error is:
Some problems were found with the configuration of task ':app:generateSafeArgsDebug' (type 'ArgumentsGenerationTask').
Type 'androidx.navigation.safeargs.gradle.ArgumentsGenerationTask' property 'applicationId' is missing an input or output annotation.

In the gradle file, replacing
classpath("android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0")
with
classpath("androidx.navigation:navigation-safe-args-gradle-plugin:2.3.5")

fixes it.

Guess The Word starter BUG

Whenever I clone and open the project, I get the following bug:-
TtileFragment.kt
findNavController().navigate(TitleFragmentDirections.actionTitleToGame())

TitleFragmentDirections is not being recognized.

Refer to the screenshot for proof:-

How to fix it?

deprecated method ViewModelProviders.of(this) in Mars Real Estate- Starter

Mars Real Estate- Starter has deprecated method to initialize view model

Sleep Duration and Sleep Quality

Hi, I strongly recommend moving the following lines
oldNight.endTimeMilli = System.currentTimeMillis()
updateNight(oldNight)
from onStopTracking() in SleepTrackerViewModel to onSetSleepQuality(quality: Int) in SleepQualityViewModel because if the user presses the Stop button and then closes the app when trying to get the Quality Sleep and reopens the app again, the system does not show the lastNight as an open time because when the user presses Stop button it stores the endTime immediately.

Android Kotlin Fundamentals codelab: Lesson 8.1, Starter Code

Describe the problem
The starter code has version_retrofit "2.5.0" which is too old. Last Task will build but won't work properly.

In which lesson and step of the codelab can this issue be found?
Lesson: 8.1, Task 6 ( Starter code )

How to reproduce?
Follow changes up to Task 6. Change code to support coroutines , run app on emulator, it produces following Exception : "No Retrofit annotation found. (parameter google-developer-training/android-kotlin-fundamentals-apps#1) for method MarsApiService.getProperties "

Versions

What version of Android Studio are you using?
4.0.1
What API level are you targeting?
30

Additional information
Change the "version_retrofit" to "2.9.0" will fix the problem.

codelab: android-kotlin-fundamentals

Link is not in README.md

Can you add it soon? I want to see that codlab, but I can't.

Thank you for your useful lecture. Have a nice day!

Code don't works in newer Android Studio Versions

None of the code examples works on Android Studie 2020.3.1 and jdk 16, a lot of mistakes, warnings. The gradle builts works, but the app don't start. Why don*t you build the programms from Beginning a new projekt

Handle orientation ourselves in “AndroidTrivia-Starter”?

In "AndroidTrivia-Starter", configuration changes are signaled as being handled by the MainActivity. Is there an underlying reason for this?

If not, I can submit a patch to remove this attribute.

Xray

No repository pattern starter code to download

Gradle refuse to build

Error:
Could not execute build using Gradle distribution 'https://services.gradle.org/distributions/gradle-6.1.1-all.zip'.

I tired older and newer versions, but no luck

RecyclerViewFundamentals-Starter - Unresolved reference: List

I have downloaded RecyclerViewFundamentals-Starter but there is a code with some red squiggles. I have identified that the problem is in SleepDatabaseDao.kt in the following code:

fun getAllNights(): LiveData<List<SleepNight>>

I have tried to clear caches, restart Android studio, clean the project and rebuild it. Nothing helps.

The "List" is in error color with a hint "Unresolved reference: List". A strange thing is that the project compiles and I can even launch it and it works! I am not sure if this is problem in the project or in Android studio.

However, the RecyclerViewDiffUtilDataBinding-Starter project does not have this bug and "List" is not reported as unresolved reference.

DataTransferObjects, in the DevBytes starter app , has erroneous documentation for helper function

The comments for helper function,NetworkVideoContainer.asDomainModel(), state this helper function

Convert Network results to database objects

However, it actually converts the results to a domain model objects (DevByteVideo) and the comment should be fixed to reflect such a case.

A Method Missing in GuessTheWord-Starter

As per the Udacity Course on Developing android apps in Kotlin there should be gameFinished method already in GameFragment but there is not.

Update old android.arch.navigation.* dependencies to androidx.navigation.*

android-kotlin-fundamentals-starter-apps/RecyclerViewFundamentals-Starter/app/build.gradle

Lines 76 to 77 in 00739f8

    
           implementation "android.arch.navigation:navigation-fragment-ktx:$navigationVersion" 
        
           implementation "android.arch.navigation:navigation-ui-ktx:$navigationVersion"

Old dependencies are outdated. Update these to link to new dependencies? i.e.

    implementation "androidx.navigation:navigation-fragment-ktx:$navigationVersion"
    implementation "androidx.navigation:navigation-ui-ktx:$navigationVersion"

Base URL in MarsApiService.kt

In MarsRealEstate-Starter project BASE_URL is wrong. It must be "https://android-kotlin-fun-mars-server.appspot.com"

Why repository isn't suggested as a singleton?

In the Repository lesson (9.1) a repo is set up step by step, hiding DB-cached network resources.

How come it is not suggested to ever create just one of those?

Neither does it protect itself against concurrent multiple cache refreshes (by multiple repo instances). It's a blunt Dao.insertAll at the end of a refresh.

There isn't a code button to download the zip file and also no link to clone!
