What’s new: It’s now even easier to find your Google Drive files wherever and whenever you need them. With this launch, Drive files and folders are now indexed via Firebase App Indexing and appear as results when you search for them in the Google app on your Android phone. Simply type your query and tap the “IN APPS” tab to view any Drive files relevant to your search. Select those files to open them in the appropriate app.
Visit the Google Play Store to download the latest versions of the Drive Android app.
