Tips Hackathon: Idea•OOT is Bad IdeaEvery hackathon has a topic. Don’t develop app that out of the topic.

•Problem SolutionYour app must solve the problem. Less technology but solve the problem better than less solution but lot of technology.

•Wow FactorPrepare cool stuff that can make jury excited.

•Focus to Demo: Hard code? Why not?Don’t develop full version of the app. You not have much time for present it to the judgment session. Even, you only have 1 minute to demo. Focus to the core.

Get Things Prepared

•The Team: Coder & PresenterHackathon wasn’t just about coding.

•Learn Hackathon Environment, First: API

•Create To Do List

•Never Forget Judgment PointsProblem Solution, Originality, User Friendly, API Implementation, Readiness, etc.

Steal Start is Fine

•Setup Group Chat

•Setup Project: User Interface, Library

•Setup Git

•Setup Cloud Service / Web Service

During Hackathon

•Take Frequent BreaksDon't let you sick after hackathon

•Have Fun!

•Presentation: Less Text, Lot Screen Shoot, Make a Story, Use Usual Words.

Tricks Hackathon• ButterKnife

• Retrofit

• Cloud Service :

Azure Mobile Service

Firebase

AWS

• Json2Java : http://www.jsonschema2pojo.org/

• Icons : http://www.flaticon.com/

Without ButterKnife• Declare

• Initialize

• OnClick

private Button btn_login;

btn_login = (Button) findViewById(R.id.btn_login);

btn_login.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

//execute login

}

ButterKnife• Add Pulgin apt to gradle (Project)

• Apply Plugin apt to gradle (Module)

• Add to gradle (Module)

classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

compile 'com.jakewharton:butterknife:8.3.0'

apt 'com.jakewharton:butterknife-compiler:8.3.0'

apply plugin: 'android-apt'

ButterKnife for Bind View• Declare

• Binding

@BindView(R.id.img) ImageView img;

@BindView(R.id.title) TextView title;

setContentView(R.layout.activity_news_detail);

ButterKnife.bind(this);

ButterKnife for OnClick@OnClick(R.id.share)

protected void share(){

String content;

if (isi.length() > 114){

content = isi.substring(0, 114) + " ...";

}else {

content = isi;

}

shareContent(judul, content);

}

Integrate Azure Mobile Service with Android• Add Azure Mobile Service SDK

• Add Gson Library

compile 'com.microsoft.azure:azure-mobile-services-android-sdk:2.0.2+'

compile 'com.google.code.gson:gson:2.7'

Create Model from Azure Table

public class TPromo implements Serializable {

@com.google.gson.annotations.SerializedName("id")

private String id;

@com.google.gson.annotations.SerializedName("image")

private String image;

@com.google.gson.annotations.SerializedName("title")

private String title;

@com.google.gson.annotations.SerializedName("description")

private String description;

Setup Azure Servicepublic void setupAzureService() {

try {

// Create the Mobile Service Client instance, using the provided

// Mobile Service URL and key

mobileServiceClient = new MobileServiceClient(

GlobalVariable.AZURE_SERVICE_URL,

GlobalVariable.AZURE_SERVICE_KEY,

getActivity()).withFilter(new ProgressFilter());

// Get the Mobile Service Table instance to use

mobileServiceTable = mobileServiceClient.getTable(TPromo.class);

} catch (MalformedURLException e) {

AppUtility.logD("TAG", "There was an error creating " +

"the Mobile Service. Verify the URL");

}

}

Load Dataprivate void loadPromos(){

new AsyncTask<Void, Void, Void>() {

@Override

protected Void doInBackground(Void... params) {

try {

final MobileServiceList<TPromo> result = mobileServiceTable.execute().get();

getActivity().runOnUiThread(new Runnable() {

@Override

public void run() {

tPromos = new ArrayList<>();

tPromos.clear();

for(TPromo item : result){

tPromos.add(item);

}

adapter.getData().addAll(tPromos);

adapter.notifyItemInserted(adapter.getData().size() - 1);

list.setLayoutManager(linearLayoutManager);

list.setAdapter(adapter);

}

});

} catch (Exception exception) {

AppUtility.logD("MainActivity", "get comment Error");

}

return null;

}

}.execute();

}
