Development Environment

Java8 & retrolambda

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.

DataBinding

This project tries to use DataBinding.

<TextView
    android:id="@+id/txt_place"
    style="@style/Tag"
    android:layout_marginEnd="@dimen/spacing_xsmall"
    android:layout_marginRight="@dimen/spacing_xsmall"
    android:layout_marginTop="@dimen/spacing_xsmall"
    android:background="@drawable/tag_language"
    android:text="@{session.place.name}" /

Custom attributes are also used like below.

<ImageView
    android:id="@+id/img_speaker"
    android:layout_width="@dimen/user_image_small"
    android:layout_height="@dimen/user_image_small"
    android:layout_below="@id/tag_container"
    android:layout_marginTop="@dimen/spacing_small"
    android:contentDescription="@string/speaker"
    app:speakerImageUrl="@{session.speaker.imageUrl}" />

BindingAdapter like speakerImageUrl is written in DataBindingAttributeUtil.java.

@BindingAdapter("speakerImageUrl")
public static void setSpeakerImageUrl(ImageView imageView, @Nullable String imageUrl) {
    if (TextUtils.isEmpty(imageUrl)) {
        imageView.setImageDrawable(ContextCompat.getDrawable(imageView.getContext(), R.drawable.ic_speaker_placeholder));
    } else {
        Picasso.with(imageView.getContext())
                .load(imageUrl)
                .placeholder(R.drawable.ic_speaker_placeholder)
                .error(R.drawable.ic_speaker_placeholder)
                .transform(new CropCircleTransformation())
                .into(imageView);
    }
}

Dagger2

This project uses DI library Dagger2. See classes in di package.

Orma

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 have @Table annotation.

@Table
public class Session {
    @Column(indexed = true)
    @SerializedName("id")
    public int id;

    @Column(indexed = true)
    @SerializedName("title")
    public String title;

    // ...
}

These classes are saved in database via dao/SessionDao. To know more about Android-Orma, see document.

Todo

This project is under development. Issues are managed by GitHub Project. https://github.com/konifar/droidkaigi2016/projects/1

If you have a feature you want or find some bugs, please write an issue.

For speakers

If you want to change description of your session, feel free to send PullRequest ????

You have to fix 3 json files below.

• sessions_ar.json
• sessions_en.json
• sessions_ja.json

If you can write only English or Japanese, it is good to write same description in sessions_en.json and sessions_ja.json. And if you can translate to Arabic by using GoogleTranslate, please write Arabic description in sessions_ar.json.

Thanks! Enjoy together!
