How to access an image from the phone's photo gallery?

By any chance, does anyone know how to access the phone's photo gallery? I am making an application that takes a picture of a plant leaf and analyzes the image to determine whether or not it is determine. We were hoping that we could give the user two options of taking the picture of the leaf or using an image of a leaf that the user has already taken. However, we got the picture taking part, but we do not know how to access the photo gallery.

How do I access pictures from my phone?

On your Android phone or tablet, open Google Photos . At the bottom, tap Library Find the folder under Photos on device. If available, open your device folders to find your missing item. If you want your device folder items to appear in your Photos tab, you can back them up automatically.

Where are gallery images stored?

Your photos will be in one of two areas: The Pictures folder or the DCIM folder. Photos you took with your phone will likely be in your DCIM folder, while other photos or images (like screenshots) you keep on your phone will likely be in the Pictures folder.

Do not forget to add the following permissions to AndroidManifest.xml:

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

You have to launch the Gallery App using the built-in Intents. After that, on your onActivityResult(), get the path of the selected image and load your image into your ImageView

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 >
<TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="@string/hello"
 />
<Button
 android:id="@+id/loadimage"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Load Image"
 />
<TextView
 android:id="@+id/targeturi"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 />
<ImageView
 android:id="@+id/targetimage"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 />
</LinearLayout>

Your Activity

 package com.exercise.AndroidSelectImage;

    import java.io.FileNotFoundException;

    import android.app.Activity;
    import android.content.Intent;
    import android.graphics.Bitmap;
    import android.graphics.BitmapFactory;
    import android.net.Uri;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.ImageView;
    import android.widget.TextView;

    public class AndroidSelectImage extends Activity {

    TextView textTargetUri;
    ImageView targetImage;

     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         Button buttonLoadImage = (Button)findViewById(R.id.loadimage);
         textTargetUri = (TextView)findViewById(R.id.targeturi);
         targetImage = (ImageView)findViewById(R.id.targetimage);

         buttonLoadImage.setOnClickListener(new Button.OnClickListener(){

     @Override
     public void onClick(View arg0) {
      // TODO Auto-generated method stub
      Intent intent = new Intent(Intent.ACTION_PICK,
        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
      startActivityForResult(intent, 0);
     }});
     }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK){
     Uri targetUri = data.getData();
     textTargetUri.setText(targetUri.toString());
     Bitmap bitmap;
     try {
      bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri));
      targetImage.setImageBitmap(bitmap);
     } catch (FileNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
    }
    }
    }
