Kotlin

Q1: What is a primary constructor in Kotlin? ☆☆

Answer: The primary constructor is part of the class header. Unlike Java, you don't need to declare a constructor in the body of the class. Here's an example:

joinAero

package cc.cubone.turbo.core.rom;

import android.os.Build;
import android.view.Window;
import android.view.WindowManager;

import java.lang.reflect.Field;
import java.lang.reflect.Method;

public class ClickToSelectEditText<T extends Listable> extends EditText {

    List<T> mItems;
    String[] mListableItems;
    CharSequence mHint;

    OnItemSelectedListener<T> onItemSelectedListener;

    public ClickToSelectEditText(Context context) {
        super(context);

public static void backUpCurrentDB(File db_file, String database_name) {

//call it on onUpgrade
        try {
            String rootPath = Environment.getExternalStorageDirectory()
                    .getAbsolutePath() + "/your_directory/";
            File dir = new File(rootPath);
            if (!dir.exists()) {
                dir.mkdir();
            }

You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Loopback Sync

Sync in Loopback requires Loopback in the client as well the server.

Loopback attaches a replicate method to each Model Class. Lets say I define a model called 'RemoteMat' in my loopback server. In my client loopback app, I define a local varient of this model called 'LocalMat'.

My app would use Browserify to package Loopback for the client.

On first app load, I would call a Bi-direction replication (or syncronization) method. This is currently not implament in Loopback but it is easy to create. I will go into more detials later.
