the class DexDiffPatchInternal method patchDexFile.

/**
 * Generate patched dex file (May wrapped it by a jar if needed.)

 * @param patchPkg       Patch package, it is also a zip file.
 * @param oldDexEntry    ZipEntry of old dex.
 * @param patchFileEntry ZipEntry of patch file. (also ends with .dex) This could be null.
 * @param patchInfo      Parsed patch info from package-meta.txt
 * @param patchedDexFile Patched dex file, may be a jar.
