I just started to use Android Studio. I don\'t know where to put my own properties file since there is no assets folder in the project structure.
The posted snippet
By default assets folder is placed in src/main/assets, if it does not exists create it.
src/main/assets
Then you can access the file using something like this:
getBaseContext().getAssets().open("app.properties")
