good day, I just want to ask that do you have any documentation (step by step) on how to Insert/Update/Delete in Android Studio using kotlin and postgresql for the database? I am new in android studio. I cant find any documentation I need for inserting/updating or deleting data in android studio using kotlin and postgresql.
You have to use any library like Retrofit where I assume you have postgresql as API endpoint, so simply you can go by the Retrofit documentation or many youtube tutorials, blogs
(https://www.vogella.com/tutorials/Retrofit/article.html or
https://www.simplifiedcoding.net/retrofit-android-tutorial/) which have described it. But first of all you need to have your API endpoint via which your android app can communicate with postgresql database

I am new to android development. I am developing an android application for my workplace. Can we connect directly to postgreSQL database without API using kotlin language on Android? If yes, how?. Also, can someone provide me a link to find similar results sourcebook?
I am waiting for your answers
I am doing a project which requires me to query google cloud mysql database to save, delete, retrieve and update data using app build in android studio.
I have been googling for quite some time, all the tutorials are using AppEngine. However in android studio 3.0+, there isn't any App Engine available anymore.
Please give advice / guidance on what should I do?
thanks in advance
Since Android Studio 3 doesn't support AppEngine anymore, you have two options:
Build your own custom backend (web service) to function as a layer that allows database consumption via the Android app. This will require more development effort than option 2.
Set up Firebase and use its database instead.
You will have to do a bit of research on getting Firebase up and running, but you wan't have to build a custom backend.
If using the Google Cloud MySQL database is a must, then you can't get around to foreseeing your own backend layer.
do you have any idea, experience, or links of any tutorial about how to connect Laravel with MySQL database to android application made using android studio? Thanks.
Required Elements for That
Tools :
1. PhpStorm
2. PostMan
3. Android Studio
Working with Android
You need to create api's for Database insertion, modification, deletion then Connect Api through RetroFit then Just need to implement what you want
I made an app where anyone can sell a product: you set its details and then I save it in Firebase.
On the client side (Android app) I want to be able to search for products using plain text.
I think the best way is by using Algolia but I really have no idea how to set-it up. Your help will be appreciated!
There are actually two topics in your question: how can one link Algolia to a Firebase database and how can one build an Android app with Algolia. I'll cover both in my answer.
How to link Algolia to Firebase
You will need to use a scripting language to import your existing data into Algolia and to sync the changes when your data is updated. Algolia has a guide to help you do so using Node.js.
You don't need to be experienced with Node.js to do it! Have a look at this question where an Android developer like you with no prior experience of Node.js just followed the guide:
In the first gathering of data, I just copied the integration code, did the necessary changes and ran it on Windows terminal: the data is now imported from Firebase to Algolia.
You simply need to:
Copy the code samples from Algolia's Firebase guide
Replace the credentials with yours
Run the scripts from your computer (if you never ran js scripts locally, search for a Node.js beginner's guide like this or this)
Once your data is imported in Algolia, you can move on to step 2:
How to use Algolia in your Android app
For building your search interface with Algolia, the recommended tool is InstantSearch Android. It's a toolbox that provides you plug-and-play components to build your search interface quickly: InstantSearch will handle all the network-related issues, the data-binding, and many other things so you can focus on what's specific to your app.
You can have a look at InstantSearch Android's demo apps which will show you examples what you could build using this tool, like this Media demo:
Algolia also provides an Android API Client for building apps. It lets you interact at a lower level with Algolia: you send the requests, get the results as JSONObject and decide what you want to do with it.
Most projects should use InstantSearch Android as it is built to make your development easier and faster (and it actually uses the Android API Client under the hood!)
I am currently developing an Android application, which is going to use a database from MongoLab. Another member of my team has already created a working database on mongolab.com, I am just having trouble connecting to it via Eclipse.
I have looked all around Google and at countless tutorials, but I really don't know much about what I'm doing.
The best tutorial I have found is from mkyong.com. It seems the second section labeled Java MongoDB Examples is what I am looking for, but I cannot get the library being used in those examples imported into my projects.
Is there a URL I can search for in Help >> Install New Software in Eclipse? I have downloaded the mongo-java-driver, but do not know how to incorporate that into my Eclipse.
To clarify again, I have no need to create a MongoDB, I am just trying to connect to an existing database via an Android project in Eclipse.
You must add the driver jar to your CLASSPATH, please refer to this FAQ.
If you have done this correctly Eclipse should be able to provide import for the the Mongo class if you type something like:
Mongo mongo = new Mongo("localhost", 27017);
I think you need to use the rest API provided by the Mongo Lab , not the java API. Send Http call to the server and get the response and parse it using JSON Parsor, that should do it.
Java Mongo driver 2.6 is compatible with Android.
The actual version 3.0.3 isn't compatible with Android because javax.security.sasl.* isn't implemented on Android.
I'm working on a forked version of 3.0.3 adding javax.security.sasl classes of this project https://github.com/koterpillar/android-sasl
