DroidKaigi 2017 official Android app 
DroidKaigi 2017 is a conference tailored for developers on 9th and 10th March 2017.
We use waffle.io to manage tasks. If you'd like to contribute to the project but are not sure where to start off, please look for issues labelled welcome contribute.
We've designated these issues as good candidates for easy contribution. You can always fork the repository and send a pull request (on a branch other than master).
We do accept suggestions for translations at this page.
This app depends on several libraries and plugins so make sure to set them up correctly.
This project uses Java8 and retrolambda. If you haven't set up Java8 yet, install it from here, and set env JAVA_HOME or JAVA8_HOME.
Tests are written in Kotlin!
This project tries to use DataBinding.
tView
droid:id="@+id/txt_title"
droid:layout_width="wrap_content"
droid:layout_height="wrap_content"
droid:maxLines="@{viewModel.titleMaxLines}"
droid:text="@{viewModel.title}" />
Custom attributes are also used like below.
geView
android:id="@+id/img_speaker"
android:layout_width="@dimen/image_size"
android:layout_height="@dimen/image_size"
app:photoImageUrl="@{viewModel.imageUrl}" />
BindingAdapter like photoImageUrl is written in DataBindingHelper.java.
dingAdapter("photoImageUrl")
ic static void setPhotoImageUrl(ImageView imageView, @Nullable String imageUrl) {
tImageUrl(imageView, imageUrl, R.color.grey200);
ate static void setImageUrl(ImageView imageView, @Nullable String imageUrl, @DrawableRes int placeholderResId) {
(TextUtils.isEmpty(imageUrl)) {
imageView.setImageDrawable(ContextCompat.getDrawable(imageView.getContext(), placeholderResId));
else {
Picasso.with(imageView.getContext())
.load(imageUrl)
.placeholder(placeholderResId)
.error(placeholderResId)
.into(imageView);
This project uses DI library Dagger2.
See classes in di package.
main/java/io/github/droidkaigi/confsched2017/di
cope
--ActivityScope.java : Scope annotation for objects being alive within activity lifecycle
--FragmentScope.java : Scope annotation for objects being alive within fragment lifecycle
ndroidModule.java : Provides system services(e.g. PackageManager, ActivityManager)
ctivityComponent.java :
ctivityModule.java : Provides activity-scoped objects
ppComponent.java :
ppModule.java : Provides application-scoped objects(e.g. SharedPreferences, HttpClient)
ragmentComponent.java :
ragmentModule.java : Provides fragment-scoped objects
This project uses ORM library Android-Orma. Android-Orma is a lightning-fast and annotation based wrapper library of SQLiteDatabase.
Some model classes in model package having @Table annotation.
le
ic class Session {
@Column(indexed = true)
@SerializedName("id")
public int id;
@Column(indexed = true)
@SerializedName("title")
public String title;
// ...
These classes are saved and updated in database via repository/XXXLocalDataSource.
To know more about Android-Orma, see document.
This app uses an simple MVVM (Model-View-ViewModel) architecture using DataBinding, dependency injection and OR-mapper.
model package.le
ic class Speaker {
rimaryKey(auto = false)
olumn(indexed = true)
erializedName("id")
blic int id;
olumn(indexed = true)
erializedName("name")
blic String name;
olumn
ullable
erializedName("image_url")
blic String imageUrl;
.
view package.onResume() is called.viewmodel packagesetText(), setImageResource() or setVisibility() are not used.OnClickListener() are also bound by DataBinding.ativeLayout

...

Repository class or DefaultPref class which are provided by Dagger2.ect
ionsViewModel(SessionsRepository sessionsRepository, MySessionsRepository mySessionsRepository) {
is.sessionsRepository = sessionsRepository;
is.mySessionsRepository = mySessionsRepository;
This project uses some modern Android libraries.
