Don't reinvent the wheel, use libraries
1 like462 views
The document discusses various Android libraries and tools to streamline development, emphasizing the use of libraries like Timber, Butterknife, Picasso, Robospice with Retrofit, Ormlite, Lombok, Parceler, and Dagger2. It provides practical examples of how to avoid common tasks and boilerplate code using these libraries, enhancing the efficiency and maintainability of Android apps. The document also introduces sample code snippets to illustrate the application of these libraries in real-world scenarios.
![Parceler
never again:
public static final Creator<Repo> CREATOR =
new Creator<Repo> {
public Repo createFromParcel(Parcel source);
public Repo[] newArray(int size);
}

Don't reinvent the wheel, use libraries
- 1. Don’t reinvent the wheel Modern Android Stack
- 2. Paweł Junak
- 3. Libs: ● Timber ● Butterknife ● Picasso ● RoboSpice + Retrofit ● ORMLite ● Lombok ● Parceler ● Dagger2
- 5. Timber never again: deleting logs from production app
- 6. Timber if (BuildConfig.DEBUG) { Timber.plant(new Timber. DebugTree()); }
- 9. Butterknife EditText email = (EditText) findViewById(R.id.email)
- 11. Butterknife never again: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { doStuff() } });
- 14. Butterknife @onClick(R.id.button) public void doStuff(Button b) { button.setText(); }
- 15. Butterknife ButterKnife.bind(this); ● OnCreate ButterKnife.bind(this, view); ● onViewCreated(View v, Bundle b), ● ViewHolder(View v):
- 16. Picasso never again: AsyncTask with HttpConnection downloading image
- 20. RoboSpice + Retrofit never again: AsyncTask with HttpConnection
- 22. RoboSpice
- 23. RoboSpice
- 25. Retrofit public interface GitHubService { @GET("/users/{user}/repos") List<Repo> listRep(@Path("user") String u); }
- 26. Retrofit @Headers("Cache-Control: max-age=640000") @Headers({ "Accept: application/vnd.github.v3.full+json", "User-Agent: Retrofit-Sample-App" })
- 28. Retrofit @GET("/group/{id}/users") List<User> groupList(@Path("id") int groupId, @Query("sort") String sort);
- 29. Retrofit RestAdapter restAdapter = new RestAdapter.Builder() .setEndpoint("https://api.github.com") .build();
- 30. Retrofit GitHubService serv = RestAdapter.create(GitHubService.class); List<Repo> repos = service.listRepos("octocat");
- 31. Retrofit POJO public class Repo { int id; String name; }
- 32. RoboSpice + Retrofit @Override public void onRequestSuccess(Repo repo) { // TODO forkAll } @Override public void onRequestFailure(SpiceException ex) { // TODO fail }
- 35. ORMLite @DatabaseTable(tableName = "repo") public class Repo { @DatabaseField(id = true) int id; @DatabaseField(canBeNull = false) String name; }
- 36. ORMLite No Args Constructor needed public Repo() {};
- 37. ORMLite class DbHelper extends OrmLiteSqliteOpenHelper onCreate(SQLiteDatabase db, ConnectionSource cS) { TableUtils.createTable(cS, Repo.class); }
- 38. ORMLite class DbHelper extends OrmLiteSqliteOpenHelper Dao<Repo,Integer> getDao() { return getDao(Repo.class) }
- 39. ORMLite class MainAct extends OrmLiteBaseActivity<DbHelper> Dao<Repo,Integer> repoDao = getHelper.getDao();
- 40. ORMLite Repo repo = new Repo(id, name); repoDao.create(repo);
- 41. ORMLite Repo repo = repoDao.queryForId(id);
- 42. ORMLite module in RoboSpice :)
- 43. Mention yahoo - squidb square - sqlbrite
- 44. Lombok never again: boilerplate getters, setters, constructors
- 45. Lombok @Getter @Setter public class Repo { int id; String name; }
- 46. Lombok public class Repo { @Getter int id; @Setter String name; }
- 47. Lombok @NoArgsConstructor public class Repo { int id; String name; }
- 48. Lombok @Data public class Repo { int id; String name; }
- 49. Parceler never again: public static final Creator<Repo> CREATOR = new Creator<Repo> { public Repo createFromParcel(Parcel source); public Repo[] newArray(int size); } public void writeToParcel(Parcel dest, int flags);
- 51. Parceler Parcelable pr = Parcel.wrap(new Repo()) Repo repo = Parcel.unwrap(pr)
- 52. Lombok @Getter @Setter @NoArgsConstructor @Parcel @DatabaseTable(tableName = "repo") public class Repo { @DatabaseField(id = true) int id; @DatabaseField(canBeNull = false) String name; }
- 55. Dagger2 @Module class Utils @Provides SharedPreferences provideSharedPreferences(){ return context.getSharedPreferences("pref", Context.MODE_PRIVATE); }
- 57. Dagger2 @Provides Tools provideTools(){ return new Tools(); }
- 59. Summary: ● Butterknife ● Picasso ● RoboSpice + Retrofit ● ORMLite ● Lombok ● Parceler ● Dagger2 ● Timber github.com/Polidea/OpenSourceBar-Android
