Hi, I had written code which encode image in Base64 format. It
requires Base64OutputStream class, as I know it is present in API
level 8, but I want to develop application for G1(API level- 4). I had
download source code for BAse64OuputStream class from
http://commons.apache.org/codec/
this URL and save in src folder of android application . The program
compiles and when I installed and run application on G1 it gives me
error as
java.lang.VerifyError .
And Logcat gives following error as

I know it is because of Java source that was compiled against
the one of the other versions . But how to write code for G1 which
encode image? So I had tried using InputStream class as
public void encodeImage()
{
try
{
out = new PrintWriter("c:/program1/zzz.txt");
InputStream inputStream = new FileInputStream
("c:/program1/
tt.jpg");
OutputStream outputStream = new
FileOutputStream("c:/program1/
zzz.txt");
byte[] b = new byte[1024];
while((read= inputStream.read(b))>0)
{
System.out.println ("Inside while");
inputStream.mark(b.length);
String encoded = Base64.encode(b);
//System.out.println (encoded);
out.print(encoded);
out.flush();
//bas.write(b);
}
out.close();
}
catch (Exception e)
{
System.out.println (e);
}
}
But this code produce encoded string but when I decode it , at
http://www.opinionatedgeek.com/dotnet/tools/base64decode/ this site
then it gives me error as The input is not a valid Base-64 string as
it contains a non-base 64 character, more than two padding characters,
or a non-white space character among the padding characters.
Please help me how to encode image?
