How to save Image to external Storage in android?

Question

I want to store Bitmap image in external storage but I am getting an error creating the file directory.

This is my code.

private void saveImage(Bitmap bitmap){
        String root = Environment.getExternalStorageDirectory().toString();
        File directory = new File(root + "/Wallpapers");
        boolean wasSuccessful = directory.mkdirs();
        if(!wasSuccessful){
            Toast.makeText(context, "Error Creating directory", Toast.LENGTH_SHORT).show();
        }
        Random generator = new Random();
        int n = 10000;
        n = generator.nextInt();
        String fname = "Wallpaper-"+n+".png";
        File file = new File(directory, fname);
        if (file.exists()){
            file.delete();
        }
        try {
            FileOutputStream out = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            out.flush();
            out.close();
            Toast.makeText(context, "Wallpaper Saved Successfully", Toast.LENGTH_SHORT).show();
        }catch (Exception e){
            Toast.makeText(context, "Error Saving Wallpaper", Toast.LENGTH_SHORT).show();
            e.printStackTrace();
        }

    }

I already write the permission in android manifest.

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

I've already tried out many solutions but it cannot resolved my issue.

It is not enough to write permissions in manifest file any more! You must always ask the user to give them and check every time before using. — Psytho, Jan 31 '19 at 07:59

Thanks it worked! But the problem is that the saved image is not showing in the gallary. — M Umer, Jan 31 '19 at 08:02
You need to scan your image for it to appear in the gallery, check this out https://stackoverflow.com/a/29714851/2164363 — Bach Vu, Jan 31 '19 at 08:07

The image is storing in the phone memory not in sd card. What is this error? — M Umer, Jan 31 '19 at 08:11

Writing simple example to store bitmapImage Image given as follows. please try it out ...

    //Get file name and bitmapImage and call the method ()
    //Bitmap bitmapImage  = ImageUtil.getInstance().changeImageRotated(cameraUri, bitmapImage, ImageUtil.TypeMode.CAMERA);
    //String fileName = String.valueOf(getCurrentTimeStamp());
    //ImageUtil.getInstance().saveImage(bitmapImage, fileName);

    //Here is function to save bitmap image to internal storage
    public Boolean saveImage(Bitmap imageData, String fileName) {
    String savePath = getFilePath(AppConst.getInstance().IMAGE_DIR_APPLY);
    isPathMade(savePath);

    File file = new File(savePath, fileName);

    FileOutputStream fileOutputStream = null;
    ObjectOutputStream objectOutputStream = null;
    boolean keep = true;

    try {
        fileOutputStream = new FileOutputStream(file);
        imageData.compress(Bitmap.CompressFormat.PNG, AppConst.getInstance().PARKING_APPLY_IMAGE_COMPRESS_QUALITY, fileOutputStream);
    } catch (Exception e) {
        keep = false;
    } finally {
        try {
            if (objectOutputStream != null) {
                objectOutputStream.close();
            }
            if (fileOutputStream != null){
                fileOutputStream.close();
            }
            if (!keep) {
                file.delete();
            }
            return true;
        } catch (Exception e) {
            Logger.e(TAG, "saveImageToCache Exception is " + e.toString());
        }
    }
    return false;
}
