How to save url images in app based folder? [duplicate]

Question

i am downloading the image from database and saving in download but want to save it in my own app named folder.

fabDownload = (FloatingActionButton) findViewById(R.id.fabDownload); fabDownload.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { //check permission if (ActivityCompat.checkSelfPermission(ViewWallpaper.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, Common.PERMISSION_REQUEST_CODE); } else { AlertDialog dialog = new SpotsDialog(ViewWallpaper.this); dialog.show(); dialog.setMessage("Please wait......"); String fileName = UUID.randomUUID().toString() + ".png"; Picasso.with(getBaseContext()) .load(Common.select_background.getImageLink()) .into(new SaveImageHelper(getBaseContext(), dialog, getApplicationContext().getContentResolver(), fileName, "CreativeGraphy Live Wallpaper Image")); } } });

to save i used image helper bitmap so i wanna know how can i add folder to save this images

SaveImageHelper

package com.blipclap.creativegraphy.Helper;

import android.app.AlertDialog; import android.content.ContentResolver; import android.content.Context; import android.graphics.Bitmap; import android.graphics.drawable.Drawable; import android.provider.MediaStore; import android.widget.Toast; import com.squareup.picasso.Picasso; import com.squareup.picasso.Target; import java.lang.ref.WeakReference; /** * Created by Vinit on 3/26/2018. */ public class SaveImageHelper implements Target { private Context context; private WeakReference<AlertDialog> alertDialogWeakReference; private WeakReference<ContentResolver> contentResolverWeakReference; private String name, desc; public SaveImageHelper(Context context, AlertDialog alertDialog, ContentResolver contentResolver, String name, String desc) { this.context = context; this.alertDialogWeakReference = new WeakReference<AlertDialog>(alertDialog); this.contentResolverWeakReference = new WeakReference<ContentResolver>(contentResolver); this.name = name; this.desc = desc; } @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { ContentResolver r = contentResolverWeakReference.get(); AlertDialog alertDialog = alertDialogWeakReference.get(); if (r != null) MediaStore.Images.Media.insertImage(r, bitmap, name, desc); alertDialog.dismiss(); Toast.makeText(context, "Download succeed ", Toast.LENGTH_SHORT).show(); } @Override public void onBitmapFailed(Drawable errorDrawable) { } @Override public void onPrepareLoad(Drawable placeHolderDrawable) { } }

call it after download in SaveImageHelper class:

private void saveImage(Bitmap bitmap,String fileName) { ByteArrayOutputStream stream = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); byte[] byteArray = stream.toByteArray(); File downloadfolder= new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/NewFolder"); if (!downloadfolder.exists()) { downloadfolder.mkdir(); } File file = new File(downloadfolder, fileName); try { FileOutputStream fos = new FileOutputStream(file); fos.write(byteArray, 0, byteArray.length); fos.flush(); } catch (Exception e) { e.printStackTrace(); } }

should i call after this line MediaStore.Images.Media.insertImage(r, bitmap, name, desc);

File folder = new File(Environment.getExternalStorageDirectory() +File.separator + "YOUR_APP_NAME"); boolean success = true; if (!folder.exists()) { success = folder.mkdirs(); } if (success) { try { bm.compress(Bitmap.CompressFormat.JPEG, 100, new FileOutputStream(new File(Environment.getExternalStorageDirectory() + File.separator + "YOUR_APP_NAME" + File.separator + "file_name" + ".jpg"))); Toast.makeText(getActivity(), "Downloaded", Toast.LENGTH_SHORT).show(); } catch (FileNotFoundException e) { e.printStackTrace(); } } else { // Do something else on failure }
