Re: [android-developers] What is difference between the Android App downloaded using Google Play store and the one directly installed?
Thanks for your help. I downloaded and installed one paid Android app using Google Play Store in phone with Android OS 4.3. I wrote one test application which enumerates list of installed apps and prints apk download location them. When I tested this app, I found that, this paid app was downloaded at /mnt/asec. In this location, the directory named by that app's package name was created and it was having following files: - res.zip (containing res directory, AndroidManifest.xml) - pkg.apk - libs directory On Tuesday, September 24, 2013 7:56:12 PM UTC+5:30, Nikolay Elenkov wrote: On Tue, Sep 24, 2013 at 11:16 PM, gauri gauri...@gmail.com javascript: wrote: How does Android split APK?

How does Android split APK? What part of APK is stored in /data/app and what part is stored in /data/app-asec? On Monday, September 23, 2013 7:53:34 PM UTC+5:30, gauri wrote: Thanks Nikolay!!!

[android-developers] What is difference between the Android App downloaded using Google Play store and the one directly installed?
Hello, The android app downloaded/purchased from Google Play is stored in /data/app directory. Does Play Store or android system modify the apk after download? I have calculated message digest of apk before it's upload to Play store. I am calculating message digest of the downloaded apk (present at /data/app) and verifying it with the digest stored in my app. When I purchase it from Play store, after my app launch, digest verification is getting failed. I found that the message digest which I have stored in app and the digest which I am calculating at run time are differing. Am I going in right direction? Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.
