i created an android app(simple cocos2d-x project) that in this project i have a method that takes a string and then render it, in initialize state of my app i pass the "abcde" as parameter to this method. This works fine in windows and android devices. but when i open SO file that placed in apk and edit any of character of "abcde" string and then replace so file with older so in apk file, the apk does't install on android devices. I get this error when trying to install the apk : application not installed.
anyone can explain me why this happen??
