How to create an App to open Camera through Intent and display captured image

 

Step 1:Firstly create a new Android Application. This will create an XML file “activity_main.xml” and a Java File “MainActivity.Java”. Please refer to the pre-requisites to learn more about this step.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/White"
    android:orientation="vertical"
    android:weightSum="3"
    tools:context=".LoginActivity">
    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_margin="30dp"
        app:cardCornerRadius="25dp">

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/parselboy"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/ic_baseline_photo_camera_24" />
        <TextView
            android:id="@+id/parselboytv"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:padding="5dp"
            android:text="Click Parsel Boy Pice"
            android:textColor="@color/textcolor"
            android:textSize="18dp">

        </TextView>

    </androidx.cardview.widget.CardView>




</LinearLayout>

Step 2:

Add permission in AndroidManifest file in android app

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />

Step 3: Now Start Coding in MainActivity. java File
