android - java.lang.ArithmeticException: divide by zero when compress image from pick gallery

Question

I'm getting error java.lang.ArithmeticException: divide by zero when compress image from pick gallery. this Is my code:

 public String compressImage(String filePath, String outputFilename) {

        Bitmap scaledBitmap = null;

        BitmapFactory.Options options = new BitmapFactory.Options();

        options.inJustDecodeBounds = true;
        Bitmap bmp = BitmapFactory.decodeFile(filePath, options);

        int actualHeight = options.outHeight;
        int actualWidth = options.outWidth;
        Log.i("INFO", "ActualHeight Input: " + actualHeight);
        Log.i("INFO", "ActualWidth Input: " + actualWidth);

        float maxHeight = 816.0f;
        float maxWidth = 612.0f;
        float imgRatio = actualWidth / actualHeight;
        float maxRatio = maxWidth / maxHeight;


       ............

        return outputFilename;
    }

the error get in lin : float imgRatio = actualWidth / actualHeight; so how to fix it?

Answer 1

The fact that you are getting the exception says that division by zero is occurring, and that options.outHeight is returning zero. You need to find out why that is happening. If Log.i("INFO", "ActualHeight Input: " + actualHeight); returns you something other than null, provide us more details.
