To cut a lengthy story quick – I didn’t managed to use one to fake Tinder application with time

This past year, one-day before Valentine’s day are real, I got the new glorious idea (ironie) in order to shock my pleasant partner which have another android app with the Romantic days celebration. Exactly who said computer system science can not be personal?

The idea is actually simple: I needed to create an android os app you to imitates and you may seems particularly Tinder but instead off demonstrating real anyone nearby, We faked that which you in order for merely my personal character gets shown thus she merely can choose me personally. Almost what you is hard coded but the chatting part. To save work I did not must build my personal very own backend to save texts and offer a lay api. Rather I thought i’d fool around with GCM to send and you can submit cam texts mode my girlfriend’s phone to my phone and the other way around. That expected to shop the received chat messages towards the a local SQLite database on the profiles unit. Therefore a database library is requisite.

Database

One reason why is that i had not located a and simple databases abstraction coating library. I can see merely a greatest you to definitely obtain the work done, however, you to was not what i desired to do. More over, I happened to be interested in a library you to coordinated next standards:

SQLBrite DAO

  • Native SQL: I do not such ORM libraries since usually they need understand their particular ask words and declarative dining table schemas. To build productive issues I need to can fool around with you to ORM library (We check you Hibernate!). Basically transform ORM library one-day, I want to learn how to build successful inquiries once again to possess the newest ORM library. More over, ORM libraries keeps their particular implementations simple tips to help save and you can take care of interactions. Possibly, you have to adjust their model (pojo) groups and come up with effective requests it is possible to even though away from an ORM execution outline. I’m very regularly SQL that is universal useable (definitely in addition to beyond your android os business). I know already how to attract efficient issues for the SQL. For this reason, I want to produce my question in the sheer local SQL. Fundamentally, We came to the conclusion that concealing SQL is not necessarily the best tip.
  • Based on RxJava: Of many developers are thinking about Rx programming, since the Rx programming offers practical the same operators such as flatMap() etc. Many hardly understand one to that with RxJava they are watching investigation. For this reason, they won’t know Rx coding anyway. Not only is it from the changing study. Rx implements brand new observer development. You’re signing up for an observable to acquire position. That like an effective http effect, nevertheless genuine fuel of observer pattern and you may RxJava can get noticed and you may utilized by making a data source observable you to is also develop over and over again activities, particularly a databases really does: As soon as the research on your own database could have been altered, every readers are told in regards to the alter of the emitting factors (with the intention that onNext() gets titled once again).
  • Immutability: Every ORM built library misses the period. I am not probably give an explanation for pros and cons out-of immutability. I recommend to read through Productive Java by the Joshua Bloch or possess a peek at javapracties which figures within the key one thing.

I know that will get sounds like an overkill to have eg a simple software for instance the phony Tinder app try. It stores chat messages to the a database. Once i create an application, I would like to make sure that it’s make the best way and you may furthermore, with each the newest application (despite such as for instance a little software including the bogus Tinder app) We improve my knowledge and you can see new stuff.
