[android-developers] Re: How to avoid reverse engineering of an APK file?
If the code if obfuscated I don't see anyone easily reading your code. The only things that will remain are literal strings for example, but reverse engineering the whole obfuscated code will be hard if not impossible to get the logic behind.

Re: [android-developers] Re: How to avoid reverse engineering of an APK file?
On this track, if the idea is to make it hard for the repackagers, you can
check your package signatures to make sure they were signed with your
private key and if not, raise an error (and perhaps send yourself an email
alert). You can do this by embedding your public key in your code and use
it to verify a signature.
Now if you are worried about reverse engineering so they can steal
algorithms/ideas, {Dex,Pro}guard are the obvious options. They don't solve
everything, but a lot of things.

Use your mind. Generally, these APK repackagers go for the first version.
When you deploy your app, have it shut down at a predetermined date. Make
sure you put out an update prior to the cut-off date that either disables
the shut-down, or furthers the date.
All of the people that got you app from the repackagers, will find the app
no longer works. You can advise them to download from official sources at
that point.

Generally someone doesn't really care about the way you wrote your java code. Few people have code that actually needs protecting. If you're running something you don't want to give out to someone, you should never be sending the code to them anyway (you should run it via a service).

you can open it in Total Commander just in the directory with cd apk need to type the name of the file and it will go into it as a folder вторник, 14 апреля 2015 г., 12:18:47 UTC+4 пользователь bo написал: HI All please any body help to restrict extracting apk .
