Capture Image from camera and store in Firebase RealTime DataBase

I am creating an inventory app for a friend's crystal specimens in Kotlin. The intended logic is:

However, I am unsure how to store the image in Firebase RealTime DataBase. I have seen examples of this process in Java and it requires in the onActivityResult, data.data be converted to a bitmap before storing but I do not fully understand enough to convert this. I was hoping someone could explain the hows and whys of storing images from the camera and not from the camera into the firebase.

My code is below and I add some questions.

RockEnry.kt

package com.inven.rock_stock

import android.content.Intent
import android.graphics.Picture
import com.google.firebase.database.FirebaseDatabase
import com.google.firebase.database.core.Context

class RockEntry {
    var name = ""
    var purchDate = ""
    var local = ""
    var mine = ""
    var weight = ""
    var paid = ""
    var asking = ""
    var description = ""
    var dimensions = ""

    constructor(name:String,purchDate:String,local:String,mine:String,
                weight:String,paid:String,asking:String,description:String,dimensions:String,){
        this.name = name
        this.purchDate = purchDate
        this.local = local
        this.mine = mine
        this.weight = weight
        this.paid = paid
        this.asking = asking
        this.description = description
        this.dimensions = dimensions

how do I store picture in constructor?

MainActivity

package com.inven.rock_stock

import android.app.Activity
import android.content.ActivityNotFoundException
import android.content.Intent
import android.os.Bundle
import android.provider.MediaStore
import androidx.appcompat.app.AppCompatActivity
import com.google.firebase.database.FirebaseDatabase
import kotlinx.android.synthetic.main.activity_main.*

var CAMERA_REQUEST_CODE = 0
var database = FirebaseDatabase.getInstance().reference

class MainActivity : AppCompatActivity() {  
    private val TAG = "MyActivity"
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)


        button.setOnClickListener {
            var name = name.text.toString()
            var local = locality.text.toString()
            var mine = mine.text.toString()
            var weight = weight.text.toString()
            var dimensions = dimensions.text.toString()
            var paid = paid.text.toString()
            var asking = asking.text.toString()
            var description = description.text.toString()

            database.child("Rocks").child(name.toLowerCase()).setValue(
                RockEntry(
                    name,
                    local,
                    mine,
                    weight,
                    dimensions
                    paid,
                    asking,
                    description


                )
            )
        }

        imageBtn.setOnClickListener {
            takePicture()
        }
    }


    private fun takePicture() {
        CAMERA_REQUEST_CODE = 222
        val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
        try {
            startActivityForResult(takePictureIntent, CAMERA_REQUEST_CODE)
        } catch (e: ActivityNotFoundException) {
            // display error state to the user
        }
    }


    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            CAMERA_REQUEST_CODE -> {
                if (resultCode == Activity.RESULT_OK && data != null) {

println("What do I need to do to get picture into firebase?")

                    val singularity = data.data

                    }

                }

            }

        }

    }

I guess I am having some conceptual issues on:

I found some examples in Java here, (which I probably should have created this project in) but my conversion is pretty ugly at this point.
here's the doc i've been staring at photobasicsDoc, uploadDoc

Solution

  • My misconception was that FireBaseDatabase & FireBaseStorage were one in the same.

    I still welcome input on the post, questions that still stand:
