Peyu:

I'm new at Android Studio and I'm trying to make a simple app. All I want it's to pick an image from Gallery and show it in an imageView. this is what I got until now:

Activity:

package com.example.peyu.bellatrix_01b;

import android.content.Intent;  
import android.net.Uri;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class ImageActivity extends AppCompatActivity {

public final static String TAG_LOG = ImageActivity.class.getSimpleName();
public static final int PICK_IMAGE = 100;
public Uri imageURI;
public ImageView imgPicture;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_image);

    Button btnAbrirImagen = (Button) findViewById(R.id.btnAbrirImagen);
    ImageView imgPicture = (ImageView) findViewById(R.id.imgPicture);

}

public void AbrirImagen(View v) {

    Intent photoPickerIntent= new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
    startActivityForResult(photoPickerIntent, PICK_IMAGE);

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {


    if(resultCode == RESULT_OK && requestCode == PICK_IMAGE){

        imageURI = data.getData();
        imgPicture.setImageURI(imageURI);

    }


}
}

I Understand that the resultcode is getting a -1, but I don't know why... any idea?? thank you
