6 years ago Yes, this demo activity specifically only creates a text file. https://github.com/gsuitedevs/android-samples/blob/master/drive/demos/app/src/main/java/com/google/android/gms/drive/sample/demo/CreateFileInAppFolderActivity.java#L34
You can look at the Quickstart sample for a demo on how to upload an image file. further:https://github.com/gsuitedevs/android-samples/blob/master/drive/quickstart/app/src/main/java/com/google/android/gms/drive/sample/quickstart/MainActivity.java
CreateFileInAppFolderActivity doesn't show how to upload anything no content is set on the Drive Contents.
