No problem. We’ve got an app just for you.
Let us show you how easy it is to use Google Drive from within your apps.
In this tutorial we show you how to display a file picker showing the folders and files in the user’s Google Drive. The user can then select a folder or a file and some of its metadata is then displayed in the LogCat. (Have you seen our LogCat tutorial? Using Android’s Log class API to debug Android application code).
Google Drive is your storage in the sky.
You can use it like a local drive and access it from anywhere from any device.
Our tutorial shows you how to upload a text file from within your app to the user’s Google Drive. We also show you how to download the contents of the uploaded file.
Got an app using activities that you want to convert to using fragments?
We’ll show you how easy it is to convert activity apps to fragment apps. It’s no big deal.
You can grab the power of Flickr, Youtube, Twitter and thousands of other powerful online applications, presenting their data from within your apps. We’ll show you how with this simple, easy to follow tutorial app.
Our tutorial shows you how to use an image repository’s API’s to access their image gallery.
We also show you how to use the OkHttp library to do network uploads, downloads and queries.
Finally, we also show you how to use the Picasso library to download, cache and display images in a RecyclerView widget.

The launch mode specifies how a new activity should be associated with the current task.
Before trying to make sense of this, let’s first have a look at:
Users can interact with their Smart Android devices using hardware keypads and buttons or by touching the screen.
Touching the screen puts the device into touch mode. The user can then interact with it by touching the on-screen virtual buttons, images, etc.
The device remains in touch mode across activities until the user exits touch mode.
Touching a hardware button causes the device to exit touch mode.
You can check if the device is in touch mode by calling the View class’s isInTouchMode() method.
A view or widget is usually highlighted or displays a flashing cursor when it’s in focus. This indicates that it’s ready to accept input from the user.
Focus is necessary for devices using trackballs, styluses, external keyboards and hardware buttons so that the user can see which view is ready to receive input.
Focus is not necessary when the device is in touch mode.
If you display images in lists or grids then you should consider using Picasso and RecyclerView.
Picasso is a powerful image downloading and caching library package which you include in your app build. It simplifies working with images, reducing the code that you need to use to one line of code.
Picasso is fast and easy to use and it’s FREE!
The RecyclerView widget is essentially a container that you can use to display large sets of data. It’s very efficient as it only displays a few items at a time. Views that are no longer needed are recycled and reused.
Not having to keep on inflating views saves CPU resources and valuable memory is saved by not having to keep views alive in the background.
Combine Picasso and RecyclerView and your app will move at the speed of light!
