Question

Will proguard work to obfuscate static string constants?

Answer 1

ProGuard doesn't obfuscate string constants, as mentioned in its FAQ. Its more recent specialized closed-source sibling for Android, DexGuard, provides additional application protection techniques, like string encryption and class encryption.
