Answer 1

I have found a way to do it. I opne the .apk file as a JarFile and then I can access individual files inside .apk. I believe this will only work for the .apk file that is running this code.

Here it is:

// Get Package Name
String packageName = ctx.getPackageName();

// Get classes.dex file signature
ApplicationInfo ai = ctx.getApplicationInfo();
String source = ai.sourceDir;

JarFile jar = new JarFile(source);
Manifest mf = jar.getManifest();

Map map = mf.getEntries();

Attributes a = map.get("classes.dex");
String sha1 = (String)a.getValue("SHA1-Digest");
