After a busy week and finally having time to write something, we continue to introduce another way for Android APK to prevent anti-compilation technology. Top two we talked about Shell technology (http://my.oschina.net/u/2323218/blog/393372) and runtime modification bytecode (http://my.oschina.net/u/2323218/blog/396203) , if there is something you can see in the first two articles of my blog about both of t
documentation. There are two ways of signing: one is to use the Jarsigner tool signature provided in the JDK, and the other is to use the SIGNAPK tool provided in the Android source code, which is located in the source build\tools\signapk directory of the Android system.Seventh step: Align the apk file after the signature. "Input" after signing the.

publishing organization is difficult to disguise. We can think of it as not camouflage for the time being. With the theoretical foundation, we can start to practice. So how can I obtain the public key information of the APK file? Because the Android system installer will certainly obtain the APK information for comparison, we can get some ideas and help through
we need to use the signature method to package our software. The procedure is very simple.

then aligns the APK with the Zipalign tool. The whole process does not require manual intervention. Debug certificate ExpirationThe certificate used for signing in debug mode expires after 1 years from the date it was created.
