Hello. The application from the file system is not installed but from AndroidStudio it fills perfectly and everything works. There are no memory leaks, there are no static links. I use a Yandex card in one place. Many drawable files and in some classes have a lot of text in String and StringBuilder (). on android 4.4.2. What is it for? When installing, it comes out << Application not installed >>

Android Studio can be installed by Android Studio for debugging, and in this case you do not need to sign the apk file. However, if you want to make a release build and upload it, say, on Google Play , you need to sign your apk after the build. By reference you will find all the necessary information.
