Apk Analyzer is an app that lets you analyze the APK of any app that is installed on your Android. You are even able to use it on APKs that haven't been downloaded yet, but that are stored in your device's memory.
The data you can see from each APK is as follows: general information, including the name of the package; the process name or the versioncode; certificates, including the MD5; required user permissions, etc. All this information is perfectly organized and presented.
Apk Analyzer is a very useful app, thanks to which you can take a look at any APK's data. You can also create a backup file of any APK in a matter of seconds or check the data integrity of any app.
