when converting image into base 64 encoded String android gives Out of memory on a 7967328-byte allocation. Exception

Question

I want to send images to the server for that I have to convert images into base 64 encoded String but gives me the Out of memory on a 7967328-byte allocation. exception not always but most of the time Maybe it happens because of large image size but i don't find a way to solve this problem here is my code which converts an image into base 64 String

public class ConvertImage1 {
    public static String convert(String path){
        InputStream inputStream = null;
        try {
            inputStream = new FileInputStream(path);

        byte[] bytes;
        byte[] buffer = new byte[8192];
        int bytesRead;
        ByteArrayOutputStream output = new ByteArrayOutputStream();
        try {
            while ((bytesRead = inputStream.read(buffer)) != -1) {
            output.write(buffer, 0, bytesRead);
            output.flush();
        }
        } catch (IOException e) {
        e.printStackTrace();
        }
        bytes = output.toByteArray();
        String encodedString = Base64.encodeToString(bytes, Base64.DEFAULT);
        return TextUtils.htmlEncode(encodedString);
        } catch (FileNotFoundException e1) {

            e1.printStackTrace();
        }
        finally{
            try {
                inputStream.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }   }
        return null;
        }

}

Here is the Logcat

Answer 1

This is because after converting to base64 image size become very large. Tryout small size image and you will understand this.
