Google’s next version of Android is set to launch in the third quarter of 2015. That’s when Google will release the software to the public and release the source code so that phone and tablet makers can bring the update to their users.

But developers and early adopters can try an early version. Google released an Android M Developer Preview on the first day of the Google I/O developer conference.

So what’s new in the latest version of Android? Google says there are over a hundred changes, but here are some highlights.

Auto Backup for Apps

Want to upgrade, replace, or factory reset your device, but worried that you’ll lose all of your saved app data? Android M’s got you covered.

Google is introducing automatic app data backup. Your data will be backed up to Google Drive every 24 hours as long as your device is idle, charging, and connected to a WiFi network.

back up

Then when you uninstall and reinstall an app or switch to a new device, not only will the app be downloaded again, but so will your data.

During the developer preview period users will be able to store up to 25MB of data per app. Google hasn’t announced how much data it will allow after the preview period ends, but there’s no charge to users or developers.

That said, there are some things that won’t be backed up, including some types of cached data, files located on external storage, or any files a developer explicitly says should not be backed up.

App Permissions

In earlier versions of Android, you’d see a list of permissions used by an app before you downloaded it form the Play Store. This would let you decide whether or not you wanted to install an app that could see you contact list, access your phone dialer, or use your microphone, for instance.

But you couldn’t easily download an app and just disable certain permissions unless you used unofficial tools.

perm_05

Starting with Android M, there’s a new runtime permissions model. This lets users decide whether to grant permissions when they run. You won’t have to allow any permissions when you first install an app. Instead, when you first run an app that requires a lot of permissions, it’ll ask you to enable them… but you can choose not to.

You can also go into settings later to adjust permissions for each app even after you’ve made your initial choices.

Note that developers will need to update existing apps to support Android M before they can take full advantage of the new permission model.

Apps that haven’t been updated will still show you a permission screen before you install them. But you’ll be able to disable settings selectively even on those apps… you’ll just have to deal with a scary warning letting you know that you might break something by disabling permissions on apps that haven’t been updated for Android M.

Adoptable External Storage Devices

Google Android has a somewhat complicated history with external storage devices. One of the key things that set early Android phones apart from iPhones was Google’s support of microSD cards… but over time Android has been modified to limit the ways you can actually use a microSD card.

That makes sense, since SD cards tend to be slower than built-in storage and more prone to failure, so you might not want to store all of your important data on those cards.

But some folk really like the option to use external storage… and they might be happy to know that Android M includes support for adoptable storage devices.

adopt storage

This lets you treat an external storage devices like an SD card as if it were internal storage. This lets Android encrypt and format the device to behave just like built-in storage, letting you move apps and other data between storage devices.

Improved USB flash drive support

Speaking of external storage, this is what happens when you connect a USB flash drive to a Nexus 5.

usb_01

Choose the Explore option, and a file browser opens up, letting you sift through the contents of your flash drive. You can view content in list or grid modes, with small thumbnail icons for images and other content in list view or larger thumbnails in grid mode.

usb_02

It’s interesting that the file browser seems to be pretty robust… but it only lets you explore the removable storage device. You’ll still need to install a third-party app if you want a file explorer for your device’s built-in storage.

Launcher and App drawer

The default launcher app for Android M also has a new app drawer. When you go to launch apps, you’ll see four of your most frequently used apps at the top of the screen, followed by an alphabetical list of apps… which you can scroll through.

home new

The widget menu is also now organized by app, and the home screen has been updated so that you can not only remove apps from home by dragging and dropping them to the top of the screen, you can also opt to uninstall apps from the same screen.

remove home

Dark Mode

Don’t like the white backgrounds Google put all over the place in Android 5.0 Lollipop? Now it looks like there’s an option to use a dark theme instead.

Update: This feature was available in early previews, but it has since been removed from Android 6.0. 

dark mode

You’ll only see the dark (or light) theme in the Android Settings menus. But that could change in the future.

Quick Settings

Don’t need all of the options in the Quick Settings panel? There’s a new tool available in the Settings menu called System UI tuner. It lets you remove tiles you don’t want to see and change the order of the tiles that you do want.

ui tuner

So if you never use airplane mode, but want the Hotspot icon to be at the top of the screen, you can customize your Quick Settings panel to meet your needs.

Notifications

Want to turn off heads-up notifications for specific apps? There’s an option for that… although Google now calls the action “peeking.”

m notifications

A more developer-friendly feature is support for bitmaps in notifications to create graphics on the fly for things like weather images.

Doze and App Standby (power improvements)

Google is taking steps to reduce power consumption of Android devices. One big part of that is a new feature called Doze which puts your device into a low-power sleep state when it’s not in use.

Doze uses motion detection to sense when your phone is idle and puts it into a deeper sleep state than earlier versions of Android offered, while waking the system periodically to perform pending operations.

doze

When Doze is active, wake locks are ignored, WiFi scans are disabled, sync jobs are not performed, and network access is disabled unless a high-priority Google Cloud Message. Some types of alarms are also disabled.

Google says all of this can double the idle run time of the Nexus 9 tablet.

There’s also a new feature called App Standby which disables network access for apps that haven’t been used in a while.

ignore opt

Want to make sure your device doesn’t shut down apps you need? There’s an Ignore optimizations setting that lets you tell Google which apps need to keep running, Doze and App Standby be damned.

Android Pay

Google Wallet is growing up and getting a complete overhaul. Meet Android Pay.

This is Google’s new mobile payment system which lets you tap your phone against an NFC-enabled checkout system in 700,000 stores around the country or pay for in-app purchases on your device.

android pay_01

You can link your Android Pay account with existing credit and debit cards as well as loyalty programs

Fingerprint Authentication

While some Android phones have already shipped with fingerprint sensors, they’ve relied on third-party authentication software. Now it’s being baked right into Android.

Google will allow users to unlock their devices or confirm purchases from the Google Play Store using a fingerprint scan. Developers can also use APIs to integrate fingerprint authentication into their apps.

fingerprint_01

For instance you can sign into an account, make purchases, or perform other sensitive actions that require confirmation of your identity.

Direct Share

Android’s Share tool has long made it easy to share pictures, web pages, and other item. Just tap a button, choose the app you want to share your content with, and then figure out who you want to share it with and… actually now, that does sound kind of tedious.

Android M makes things a bit easier support for Direct Share features.

direct share

Developers can specify direct share targets that will launch a specific activity. For instance when you tap the share icon in one app, it might open a contact list so that you can send a picture to a contact through Facebook, Gmail, or another app with just a few taps.

Hotspot 2.0

Want to share your phone’s mobile data connection with other devices over WiFi? Android has had a built-in hotspot feature for a while (although it doesn’t work with all phones from all carriers).

Starting with Android M, you’ll be able to choose whether to use a 2.4 GHz or a 5 GHz band, assuming you’ve got a device that supports both.

Bluetooth Stylus support

There’s improved support for a Bluetooth stylus, which lets you pair a stylus with your phone or tablet and detect not only pressure ant touch input, but also button presses.

This lets apps perform secondary actions when the button is pressed.

bt stylus

Google says this will allow any app to detect that you’re using a stylus, even on a device that doesn’t have an active digitizer.

Audio

Android M introduces support for the MIDI protocol for connecting audio hardware like keyboards or other controllers.

For folks that aren’t musicians, there’s a simpler audio improvement: volume controls which make it easier to adjust the volume of alarms, music, and notifications.

Now when you hold the volume button down for a few seconds, the volume level will slide down until it hits vibrate. Tap the slider volume button again, and it enables do not disturb mode (which you can also access from the Quick Settings panel).

Now the only sounds you’ll hear will be alarms… unless you go to the Do not disturb settings and select “total silence.” You can find this option by tapping the Do not disturb icon in the Quick Settings panel.

total silence

You can also now easily adjust volumes for notifications, alarms, and media using separate sliders. Just tap the expand icon from the volume pop-up to see three different volume levels which you can adjust.

USB options

When you connect a USB cable and tap the USB icon on your device, you now have several choices including charging only, transfer files (MTP), Transfer photos (PTP), and MIDI.

usb options
These let you decide which type of connection you’d like to make… but sadly it doesn’t look like Google remembers your last selection. I’ve had to choose MTP every time I want to transfer photos from my phone to my computer, because Android seems to default to charging only.

Text Selection

There’s now support for a floating toolbar with copy, cut, paste, and other actions when you copy text. Previously this would appear at the top of the screen instead of above the content you’d actually selected.

android m select

It’ll be up to developers to integrated the floating toolbar, so it might not be available for all apps.

Split keyboard for tablets

The Android keyboard works well enough on smartphones and tablets with small screens. But what if you’re holding a larger device in two hands? Now there’s a split keyboard that lets you type with your thumbs while holding onto a larger device like a Google Nexus 9 in landscape mode.

split

Multi-window mode

This feature is actually hidden: you need to edit your build.prop file to enable the option for multi-window mode. But once you’ve done that, you can view two apps at the same time on phones, or up to four apps at the same time on a tablet.

multi

Multi-window mode is still experimental and it’s not clear if it’ll make it into the final version of Android M, or if this is just a preview of something Google is working on for a version of Android that’s even further off in the future.

You can learn more about how the feature works in our article on multi-window support in the Android M developer preview.

Android For Work

Google’s software for enterprise users lets you maintain two separate profiles on a device: one for personal use and another for work. Data isn’t shared between the two, and there are security features in place to help your boss feel comfortable with letting you wander around with sensitive data.

work

Android M allows device owners to disable or re-enable some features including the status bar, safe boot mode, and the keyguard, allows silent app installs and uninstalls by the device owner, and adds support for auto-acceptance of system updates, among other things.

Android TV

Google is also updating Android TV with a few new features. The Android M version of the company’s OS for smart TV devices adds native support for external storage and A2DP Bluetooth streaming, so you can hook up a USB hard drive and pair your Bluetooth headphones with a Nexus Player or other Android TV device.

  1. I’m missing a key item from App permissions:

    – which apps are permitted to auto-start upon boot.

    I find tons of apps that basically never should be running except when I manually start them.
    But there they all are, running in the background, clogging up the system for their own purposes.

  2. Many features were copied from Windows/Windows Phone… switch between light and dark theme, quick settings can be modified, split keyboard, etc…

    1. :p

      But you go on looking through your irrelevant Microcruft vs Greedle glasses…

      So many silly people acting like they were stake holders for some greedy corporation or other.

      1. Well, actually I’m a programmer and build apps for Windows. Technology blogs are frequented by many professionals who work in the sector and we discuss to take our decisions on where to point our skills. Our lives really depend on those platforms because in a couple of years we can become obsolete and lose our job.

  3. And they still haven’t added supports to undo and redo typed text while iOS has had it for years.
    Seem like alot of things they added already have on cyanogen os.

    1. Google keeps playing with UI things that generally aren’t an improvement instead of giving us truly useable features.
