Android App Update, Assets Update

I have an app and it uses .txt files from assets folder. In assets folder are more directories in some depth. Later I will want to add new files to this assets folder so I'll hav

Solution 1:

The old app is just replaced by the new app.

You don't have to worry about that. Apps are always installed completely without loosing data. That is, the .apk file is just replaced. So your assets will be also updated automatically.

Here an example:

Google Play Store downloads the new .apk file.

Next, it replaces the old apk file in /data/app/ by your new apk file. That means that all the stuff that is in your new app is now available.

In this way the whole application is replaced.
