Android O Developer Preview: Our first take

Why it issues to you

Your subsequent telephone is prone to run Android O — and primarily based on our assessments, it positive seems candy.

Android Oreo, anybody? Or perhaps it’s Android Oatmeal Cookie?

No matter Google finally ends up calling it, the Mountain View, California, firm is prepping its subsequent main Android launch: Android O. On March 21, it made everything official besides the title.

Similar to final yr, Google is providing builders (and intrepid customers) the chance to test drive the new version of Android earlier than it launches publicly later this yr. Which means it’s unfinished (and slightly unstable), however packs most of the options that may make it into the ultimate model.

The primary Developer Preview is obtainable for the Nexus 5X, Nexus 6P, Nexus Participant, Pixel, Pixel XL, and Pixel C. It’s not accessible as an over-the-air replace — it must be put in manually, which isn’t for the faint of coronary heart.

Fortunately, Google’s spilled the main points about Android O in a prolonged weblog put up. And after many trials and tribulations, we managed to get Android O up and operating on a dusty outdated Nexus 6P. Right here’s all the pieces we’ve discovered, and all the pieces it’s worthwhile to know.

Android O is now in beta

Google I/O is right here and on the present, Google introduced Android O is in beta — which means that in case you’re a developer, or simply an Android hobbyist, now you can get the newest and biggest model of Android in your telephone. Be mindful, the working system is in beta mode so you need to anticipate bugs and possibly mustn’t set up it in case you don’t know what you’re doing. You possibly can join the Android O beta by heading to the signup page.

Whereas Google didn’t essentially announce any new options for O at Google I/O, it did spotlight a number of facets of the working system. For instance, the corporate talked about Mission Treble, its new initiative geared toward pushing updates to Android far quicker. Project Treble primarily permits producers to simply push low-level firmware updates to Android with out having to replace the working system as a complete.

Google can also be rushing up Android, on the whole. The corporate introduced that via plenty of working system optimizations, boot time is now quicker and apps ought to run lots higher. Additionally it is implementing “smart limits” on apps that run within the background — guaranteeing they don’t take up an excessive amount of battery life and processing.

Revamped notifications

The earlier model of Android, Android Nougat, added the flexibility to prioritize sure notifications over others. Android O tweaks that habits.

Customers can snooze alerts and schedule them to reappear at a later time, and builders can change the background shade of notifications and trigger notifications to dismiss themselves after predefined time increments: 15 minutes, 30 minutes, or 1 hour.

The snooze function is probably the obvious change, and it really works moderately nicely. After dragging a notification to the right-hand aspect of the notification shade, a clock-shaped icon seems, and tapping on it brings up the aforementioned listing of time increments. In our testing, Gmail, Slack, Allo, and Hangouts notifications all reappeared with out challenge. A phrase of warning, although: It’s simple to by chance dismiss notifications whereas pulling up the Snooze menu. Drag slowly.

After all, not all notifications are suitable. For instance: “Persistent notifications” or ongoing notifications that may’t be dismissed can’t be snoozed, both.

There’s a brand new prioritization function in Android O known as Notification Channels. Extra particulars are forthcoming, however right here is Google’s description of the way it works: If an vital e mail from a colleague is available in amongst a flood of spam, the colleague’s message will seem on high. Relying on how customers tweak Android O’s notification settings, they could not see the junk emails in any respect.

App builders can even select to combination alerts of the identical sort in a single Notification Channel. When you get a number of “tech information” updates throughout a handful of apps, for instance, they’ll present up bundled in a single channel — very like Google’s Gmail sorting, which provides granular management over what emails customers obtain notifications for.

The onus is on builders to implement Notification Channels. We’ve but to see an app that helps them, as a result of Android O is so contemporary out of the oven. We anticipate to listen to extra as the brand new model of Android progresses.


Android Nougat launched Doze, a battery-saving function that routinely “hibernated” apps operating within the background. With Android O, Google has taken that concept one step additional with “computerized limits” that place strictures on background apps — particularly those who replace location of background providers. Android O can impose “execution limits” on the latter, which restrict system entry to sure processes when the app isn’t getting used. Location limits, then again, stop apps that entry a tool’s location (through GPS or Wi-Fi) from doing so gratuitously. Google’s calling it a “important change” to the best way Android manages apps.

We’ll should run Android O via its paces to determine how dramatically the under-the-hood modifications influence battery life.

Excessive-quality Bluetooth audio

Wi-fi Bluetooth headphones, earbuds, and audio system are all the trend today, so it’s not all that stunning that Android O brings main enhancements to wi-fi audio.

New Bluetooth audio codecs promise to make music crisper, clearer, and richer than on Android variations of the previous.

Android O helps Sony’s LDAC wi-fi codec, which guarantees huge audio efficiency good points. Right here’s the gist: it lets telephones switch roughly thrice the quantity of information (990kbps) over the identical Bluetooth connection as the typical smartphone. That’s greater than twice as quick as Spotify’s requirement for Hello-Fi streaming (320kbps), and simply wanting Tidal’s lossless high quality (1,411kbps).

LDAC has been round some time — Sony launched it on the 2015 Shopper Electronics Present, and has since constructed it into its high-end Walkman music gamers, Xperia smartphones, and MDR-1000X headphones. However Android O will mark the primary time the codec’s made accessible on non-Sony units.

Sadly, not everybody will be capable to take benefit. LDAC requires that each the sending machine (a smartphone) and receiving machine (a pair of headphones) assist it — in case you don’t have cans with LDAC, you’re out of luck.

AptX, one other low-latency Bluetooth streaming format, can also be in tow. It’s hardware-dependent, however an rising variety of flagships — together with these operating Qualcomm’s newest Snapdragon processors — assist it. Android O’s audio is a dramatic improve from Android 7.zero Nougat for wi-fi followers.

Adaptive icons, picture-in-picture mode, and UI tweaks

Android O is comparatively mild on UI tweaks and modifications, however there are a number of notable ones in tow. The standing bar is cleaned up. In Android O, new icons indicating your telephone’s Wi-Fi and cellular connectivity standing sit subsequent to the battery icon. The Settings menu has been overhauled. In comparison with Nougat, there are roughly half the variety of top-level menu choices because of aggressive consolidation. Google has finished away with the slide-out menu.

Android’s System UI Tuner gained a bunch new options. Simply faucet and maintain the settings gear on the high of Android’s Fast Settings menu. When you’ve held it for a number of seconds, the gear will start to spin and slightly wrench icon will seem subsequent to it, indicating that the System UI Tuner has been enabled. To any extent further, you’ll see it close to the underside of Android’s Settings menu.

Android O offers you full management over the navigation bar’s look and habits. You’re free to alter the format of the buttons, or add an additional proper and left button. A brand new Compact mode squishes them nearer collectively. When you’re the methodical kind, you’ll be able to assign buttons custom codes that set off actions like launching the calendar app, pausing/enjoying music, and opening the default dialer.

Not all of them work equally nicely. We have been in a position so as to add a customized button for the Calendar (code 208) and Dialer (5), however others just like the Digicam (27) and Calculator (210) appeared buggy. We anticipate Google to repair these types of niggles in developer previews to return.

A second welcome addition to the System UI Tuner is lockscreen shortcuts, which let you add shortcuts to your telephone’s lockscreen. You possibly can add a devoted button for Chrome tabs, or a shortcut to the settings menu — the sky’s the restrict, actually.

A function known as Adaptive Icons let builders alter the look and form of app icons relying on what residence display theme customers choose. If a consumer swaps Android’s default theme to a customized pack they downloaded from the Google Play Retailer, for instance, app icons that faucet Adaptive Icons will routinely swap to match the styling and shade scheme of stated theme.

There’s rising proof that Android O will introduce assist for themes. Within the show settings, there’s a bit for “Machine theme” and two choices: Inverted and Pixel. The previous, as you may anticipate, swaps the colour palette of each Android settings menu — white icons develop into grey, and gray backgrounds develop into white.

Google didn’t announce themes as a part of the primary Android O Developer Preview, however we wouldn’t be shocked to see the function fleshed out down the street.

Additionally in tow with Android O is assist for iOS-style residence display badges. Apps that assist them will present animated notifications for issues just like the variety of unread messages in your e mail inbox or the variety of mentions you’ve gotten on Twitter.

Android O packs a picture-in-picture mode for movies, too, plus assist for launching actions on a secondary show and a pop-up window for third-party apps. It’s already working for apps like YouTube, however enabling it isn’t precisely a stroll within the park.

Right here’s the way to do it: Head to Settings > System UI tuner and add a cursor button to the navigation bar. Map it to keycode quantity 171, and if you’re in a suitable app, press it to allow PiP mode. Press it once more to disable PiP.

An elective “wide-gamut shade” guarantees to make apps extra vibrant and colourful than ever on high-contrast screens.

It’s incumbent on builders to assist Adaptive Icons, residence display badges, picture-in-picture mode, and wide-color gamuts — as of now, there doesn’t look like a option to manually allow them. We’ll hold looking out, nevertheless it appears we’ll have to attend for builders to do their half.

Different conveniences

Android O can also be filled with miscellaneous goodies geared toward addressing longstanding annoyances.

It’s simpler so as to add customized ringtones, alarm sounds, and notification sounds in Android O. Head to the ringtone selector within the Settings menu and choose Add ringtone. Then, you’ll be able to choose an audio file you’ve downloaded.

Excellent news in case you’re a frequent Skype consumer: Android O’s “telecom framework” will allow you to swap out your telephone’s default dialer for a third-party VoIP different.

A brand new Networking Conscious Networking function will enable Android units to speak straight with one another over Wi-Fi, even when the community isn’t linked to Wi-Fi, GPS, or mobile knowledge. There’s a low-power connection mode that permits for sharing small bits of information like sensor readings, location, and extra.

New keyboard shortcuts together with “arrow and tab button navigation” will make utilizing bodily keys rather less painful.

An autofill API will make it simpler for password, deal with, and consumer title managers to register themselves because the system’s official autofill app. When a consumer encounters a password discipline, they’ll be capable to paste a saved password from a listing.

Apps put in from exterior the Play Retailer now should be granted permission manually. In Android Nougat and older, a toggling a common “Set up from unknown sources” possibility was sufficient to allow any third-party app entry to your telephone’s inner storage. Now, you’ll be prompted each time an app makes an attempt an set up.
