        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
    }
}

        dir.mkdirs()
        val fileName = String.format("%s_%d.jpg", "Image", System.currentTimeMillis())
        val outFile = File(dir, fileName)

Save bitmap to location

try (FileOutputStream out = new FileOutputStream(filename)) {
    bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance

} catch (IOException e) {
    e.printStackTrace();

Save bitmap to android default pictures directory

String path = Environment.getExternalStorageDirectory().toString()
            + "/Pictures/Keshavarzi/" + "screenshot-" +

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) {

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

Android Studio - Save bitmap to gallery is incorrect

Try this one, maybe it helps you.

private void saveImage(Bitmap bitmatFile, String image_name) {

    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root);
    myDir.mkdirs();
    String fname = "Image-" + image_name+ ".jpg";
    File file = new File(myDir, fname);
    if (file.exists()) file.delete();
    Log.i("LOAD", root + fname);
    try {
        FileOutputStream fos = new FileOutputStream(file);
        bitmatFile.compress(Bitmap.CompressFormat.JPEG, 90, fos);
        fos.flush();
        fos.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
