Image Download From URL and save in the folder

Step 1:

Add Dependencies app/Gradle/build.gradle −

dependencies {

    implementation libs.appcompat
    implementation libs.material
    implementation libs.activity
    implementation libs.constraintlayout
    testImplementation libs.junit
    androidTestImplementation libs.ext.junit
    androidTestImplementation libs.espresso.core

    implementation 'com.github.CodeWithTamim:NasaDownloader:1.0.0' //add library
    
}

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

Step 2:

Add Library  app/Gradle/settings.gradle −

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' } //add jetpack url
    }
}

Step 3:

File open res/layout/activity_main.xml file −

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_margin="10dp"
        android:gravity="center"
        android:orientation="vertical">

        <EditText
            android:id="@+id/urlED"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="input image url..."
            android:inputType="text" />

        <androidx.appcompat.widget.AppCompatButton
            android:id="@+id/downlaodBTN"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background="#4CAF50"
            android:padding="5dp"
            android:text="Download" />

    </LinearLayout>
</RelativeLayout>

Step 4:

File open com.microappvalley.newtestproject/MainActivity.java file −

package com.tutorialb.imagedownloadfromurlandsaveinthefolder;

import android.os.Bundle;
import android.view.View;
import android.widget.EditText;

import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.AppCompatButton;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;

import com.nasahacker.downloader.NasaDownloader;

public class MainActivity extends AppCompatActivity {

    EditText urlED;
    AppCompatButton downlaodBTN;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_main);
        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
            Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
            return insets;
        });

        urlED = findViewById(R.id.urlED);
        downlaodBTN = findViewById(R.id.downlaodBTN);

        NasaDownloader downloader = new NasaDownloader("SavingDirName");

        downlaodBTN.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String imageURL = urlED.getText().toString();

                if (!downloader.isPermissionGranted(MainActivity.this)) {
                    downloader.requestPermission(MainActivity.this);
                } else {
                    downloader.downloadImage(MainActivity.this, imageURL, NasaDownloader.IMAGE_TYPE.JPEG);
                }
            }
        });

    }
}
