Question

I am not able to send photo to server in Version 6.0.1 and above below versions its working fine. Facing below error.

Camera Utils Class code where its showing the error with getBytes method and save to internal method:

public  static String saveToInternal(Context context, Uri tempUri)

    OutputStream out = null;
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 10;
    Bitmap bmp= BitmapFactory.decodeFile(tempUri.getPath(),options);
    File destinationInternalImageFile = new File(getOutputInternalMediaFile(context, 1).getPath());
    byte[] bitmapdata=getBytes(bmp);
    ByteArrayInputStream bs = new ByteArrayInputStream(bitmapdata);
    try {
        destinationInternalImageFile.createNewFile();
        out = new FileOutputStream(destinationInternalImageFile);
        byte[] buf = new byte[1024];
        int len;
        while ((len = bs.read(buf)) > 0) {

        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    finally {
        try {
            if (bs != null) {
                bs.close();
            }
            if (out != null) {
                bs.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    Log.e(TAG, "File Size : " + (destinationInternalImageFile.length() / 1024) + "KB");
    return destinationInternalImageFile.getPath();
}

// convert from bitmap to byte array

    public static byte[] getBytes(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG,50, stream);
    return stream.toByteArray();
}

// convert from byte array to bitmap

    public static Bitmap getImage(byte[] image) {
    return BitmapFactory.decodeByteArray(image, 0, image.length);
}

Clearly error shows that there is no image with that name in your file or directory. and null is going in to your compress function. — Muhammad Saad, Dec 20 '17 at 11:32

Saad i am clicking the image and it was in the internal storage of the device while uploading it to server its crashing. — Chaudhary Amar, Dec 20 '17 at 11:37
did you ask runtime permission for `Version 6.0.1 and above` @ChaudharyAmar — AskNilesh, Dec 20 '17 at 11:39

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.graphics.Bitmap.compress(android.graphics.Bitmap$Com‌pressFormat, int, java.io.OutputStream)' on a null object reference.

This tells it all.

Bitmap bmp= BitmapFactory.decodeFile(tempUri.getPath(),options);

You have no bitmap! bmp==null.

Check before use! Before you call .compress() on it.

But your real mistake is

 Bitmap bmp= BitmapFactory.decodeFile(tempUri.getPath(),options);

You use a wrong path:

/external_files/DCIM/Camera/JPEG_20171220_163728_946425952.jpg

That is a non existing 'path' to begin with.

Change your code to.

InputStream is = getContentResolver().openInputStream(tempUri);
Bitmap bmp= BitmapFactory.decodeStream(is,options);

There is nothing to check. Instead you should check for 'bmp==null' and not continue with your code if so. Add: `if (bmp==null){Toast ( ... bitmap is null ...); return;}`. – greenapps Dec 20 '17 at 11:49
what i have to do if the bmp is null. – Chaudhary Amar Dec 20 '17 at 11:54
