Save Bitmap to Location

Save bitmap to location

try (FileOutputStream out = new FileOutputStream(filename)) {
    bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
    // PNG is a lossless format, the compression factor (100) is ignored
} catch (IOException e) {
    e.printStackTrace();
}

C# Bitmap.Save path

Change that to

b.Save(Application.StartupPath + "\\img.jpg");

The problem here is that System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase doesn't return the executable directory as you might have wanted.

How to Save bitmap to app folder in android

You can just do this:

try {
     FileOutputStream fileOutputStream = context.openFileOutput("Your File Name", Context.MODE_PRIVATE);
     bitmap.compress(Bitmap.CompressFormat.PNG, 100, fileOutputStream);
     fileOutputStream.close();
 } catch (Exception e) {
     e.printStackTrace();
 }

It saves your bitmap in the "files" directory in app folder.

Save bitmap image to specific location of gallery android 10

Try this code :-

private void saveImage(Bitmap bitmap, @NonNull String name) throws IOException {
    boolean saved;
    OutputStream fos;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        ContentResolver resolver = mContext.getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, name);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/png");
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/" + IMAGES_FOLDER_NAME);
        Uri imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
        fos = resolver.openOutputStream(imageUri);
    } else {
        String imagesDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_DCIM).toString() + File.separator + IMAGES_FOLDER_NAME;

        File file = new File(imagesDir);

        if (!file.exists()) {
            file.mkdir();
        }

        File image = new File(imagesDir, name + ".png");
        fos = new FileOutputStream(image);

    }

    saved = bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
    fos.flush();
    fos.close();
}

Android save bitmap to image file

1.Check it if you don't request the runtime permission yet: https://developer.android.com/training/permissions/requesting

2.Or if your android is higher than 10:
https://developer.android.com/about/versions/11/privacy/storage#scoped-storage

• After you update your app to target Android 11, the system ignores the requestLegacyExternalStorage flag.

Then you have to use SAF or MediaStore API to store the bitmap in the "public directory".

SAF:
https://developer.android.com/guide/topics/providers/document-provider

MediaStore API:
https://developer.android.com/reference/android/provider/MediaStore

public void onBtnSavePng(View view) {
    try {
        String fileName = getCurrentTimeString() + ".jpg";

        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.DISPLAY_NAME, fileName);
        values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpg");
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            values.put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/");
            values.put(MediaStore.MediaColumns.IS_PENDING, 1);
        } else {
            File directory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
            File file = new File(directory, fileName);
            values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
        }

        Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

        try (OutputStream output = getContentResolver().openOutputStream(uri)) {
            Bitmap bm = textureView.getBitmap();
            bm.compress(Bitmap.CompressFormat.JPEG, 100, output);
        }
    } catch (Exception e) {
        Log.d("onBtnSavePng", e.toString()); // java.io.IOException: Operation not permitted
    }
}

how can i change bitmap saving location

thanks everyone This works

 public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
    ContentResolver r = contentResolverWeakReference.get();
    AlertDialog alertDialog = alertDialogWeakReference.get();
    if (r != null)
       file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/CreativeGraphy";
    File dir = new File(file_path);
    if (!dir.exists()) {
        dir.mkdir();
    }
    File file = new File(dir,name );
    FileOutputStream fOut;
    try {
        MediaStore.Images.Media.insertImage(r, bitmap, name, desc);
        fOut = new FileOutputStream(file);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
        fOut.flush();
        fOut.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
    alertDialog.dismiss();
    Toast.makeText(context, "Download succeed ", Toast.LENGTH_SHORT).show();
}

How to save a bitmap on internal storage

To Save your bitmap in sdcard use the following code

Store Image

private void storeImage(Bitmap image) {
    File pictureFile = getOutputMediaFile();
    if (pictureFile == null) {
        Log.d(TAG,
                "Error creating media file, check storage permissions: ");// e.getMessage());
        return;
    } 
    try {
        FileOutputStream fos = new FileOutputStream(pictureFile);
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        Log.d(TAG, "File not found: " + e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, "Error accessing file: " + e.getMessage());
    }  
}

To Get the Path for Image Storage

/** Create a File for saving an image or video */
private  File getOutputMediaFile(){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this. 
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
            + "/Android/data/"
            + getApplicationContext().getPackageName()
            + "/Files"); 

    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    } 
    // Create a media file name
    String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
    File mediaFile;
        String mImageName="MI_"+ timeStamp +".jpg";
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);  
    return mediaFile;
} 

EDIT
From Your comments i have edited the onclick view in this the button1 and button2 functions will be executed separately.

public onClick(View v){

switch(v.getId()){
case R.id.button1:
//Your button 1 function
break;
case R.id. button2:
//Your button 2 function
break;
} 
}
