I am developing an application in Android but whenever i try to update my application (deleting the old app's files and uploading new files from my pc). After i replace files and re-install my app, i can not see any changes on my phone. It stays like the old version, like no changes are applied. btw. i change the versionCode and versionName in the manifest file and My app is not on GooglePlay store yet, only in my PC .
Please try to Clean and build the project after u updated the files in your app project if you are using Eclipse as an IDE.
