This document provides tips and tricks for rapid Android development for hackathons. It discusses using ButterKnife to reduce boilerplate code, integrating with Azure Mobile Services to access cloud data, and preparing for hackathon judging by focusing on problem solving and usability over extensive features. Sample projects demonstrate integrating ButterKnife and connecting to an Azure Mobile backend.

- 6. Tips Hackathon: Idea •OOT is Bad Idea Every hackathon has a topic. Don’t develop app that out of the topic. •Problem Solution Your app must solve the problem. Less technology but solve the problem better than less solution but lot of technology. •Wow Factor Prepare 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.
- 7. Get Things Prepared •The Team: Coder & Presenter Hackathon wasn’t just about coding. •Learn Hackathon Environment, First: API •Create To Do List •Never Forget Judgment Points Problem Solution, Originality, User Friendly, API Implementation, Readiness, etc.
- 8. Steal Start is Fine •Setup Group Chat •Setup Project: User Interface, Library •Setup Git •Setup Cloud Service / Web Service
- 9. During Hackathon •Take Frequent Breaks Don't let you sick after hackathon •Have Fun! •Presentation: Less Text, Lot Screen Shoot, Make a Story, Use Usual Words.

- 11. 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
- 12. 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'
- 13. 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);
- 14. 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); }
- 15. 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'
- 16. 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;
- 17. Setup Azure Service public 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"); } }
- 18. Load Data private 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(); }
