any small demo to encode axml

[Jasi2169]

decoding does work as expected properly and after modifying
when i try
AxmlWriter v1 = new AxmlWriter();
byte[] v2 = v1.toByteArray(); kinda stuff the output is only 44bytes
any help ?

Edited :- okay i was thinking after writing the decoded xml can be change it with text search n replace and edit our text and encode it back ? any example

Fixed myself was not using Nodevisitor :) i also closed it

Hi Jasi2169, could you provide a more detail?
I don't quite follow your question.

okay what i was doing is this

InputStream is = new FileInputStream(file);
                byte[] xml = new byte[is.available()];
                is.read(xml);
                is.close();
                AxmlReader rd = new AxmlReader(ArrayDataIn.le(xml));
                AxmlWriter wr = new AxmlWriter();

                //initial parsed
                System.out.println("==== A");
                StringWriter writerA = new StringWriter();
                Axml axml1 = new Axml();
                rd.accept(axml1);
                axml1.accept(new DumpAdapter(writerA));
System.out.println(writerA);

// and after this i was writing the writerA Stuff to the txt file stored here /sdcard/z.txt and i made modification and wanted to compile back same this way to toByteArray but result was 4kb only

/* then i saw your test example with nodevisitor which works great,
but anyway i am thinking can be compile from the above method i definately took the txt file as input stream and tried to convert to byte array and then write the new axml,maybe i might be wrong somewhere ,i wanted to add activity in the manifest as apktool doesnot compile some manifests sometime om some apps

I didnt understand how to use it. need a simple tutorial

Hi @shahril772, please check test cases. They contain several good examples.

If you need more examples, you may want to check one of my old project that was using this library (again, there is no tutorial or friendly guide): link1, link2, link3

In general, I modified the interface of the original AXML slightly so that it looks similar to ASM. If you are familiar with using ASM, using AXML shouldn't be that difficult.
