Hi Daniel,
Your post is a good news for me.
Actually, the dex jar files that were signed is so strange for me.
Currently, when DexFile wants to load a class of them (i.e. the dex
jar file), they define this class with a null ProtectionDomain
parameter. A way to fulfill the security for the dex jar file is
change this parameter to a valid ProtectionDomain object. However, I
can not really create a that object because the CodeSource object was
impossible to created by the JarVerifier is not successful. More
clearly in source code as here:
...
JarFile jf = new JarFile(path, true);
JarEntry je = jf.getJarEntry("classes.dex");
CodeSource cs = new CodeSource(url, je.getCertificates()); //<--- at
this line, je.getCertificates() return null, so the creation failed.
...
For normal jar file (i.e they have class files, not dex file), the
creation is OK.
Could you explain why it fails to get certificates?
Thank you so much.
