The Android M developer preview was recently launched at Google I/O 2015 in San Francisco.While Android Lollipop introduced a new visual aesthetic, Android M brings some much-needed stability and usability improvements which might not be as eye-catching, but may prove to be significant additions for a while to come.
Features:
1. App permissions:
Users now are able to choose to accept or deny individual permissions as they see fit. Permissions have also been simplified.Permissions will now be requested the first time you try to use a feature, not at the point of installation.
For example:
If you want to record a voice message, WhatsApp will prompt you with a one-time request for permission to use your mic: if you still wish to give it access and record the message, you can, but you don't have to. Android M is giving users greater control of the information apps can access, and this is a truly positive step forward for Android.
2. Web experience:
Chrome Custom Tabs is a new feature that gives developers a way to harness all of Chrome's capabilities, while still keeping control of the look and feel of the experience.Chrome Custom Tabs will allow apps to open a customized Chrome window on top of the active app, instead of launching the Chrome app separately. This will provide a faster and more intuitive user-experience when navigating between apps and the web. Chrome Custom Tabs supports automatic sign-in, saved passwords, autofill, and multi-process security to assist the integration of the app and web experience.
3. Fingerprint support:
This new functionality will allow fingerprint scanners to be used not only to unlock phones, but to make purchases shopping in real-life or within Play Store apps.
4. Mobile payments:
Android Pay is Google's new mobile payments system designed to make the checkout process easier and faster.Google is aiming to provide "simplicity, security, and choice," with Android Pay, allowing you to use your existing credit cards to pay for products in more than 700,000 stores in the US.
5. App links:
App links are being changed in M so that Android has a greater awareness of which apps can open content directly, instead of stopping users every time with the dialog box. If you tap a Twitter link in an email, for example, the Twitter app will open automatically instead of prompting you to ask if you want to use Twitter to view it.You may be familiar with the "Open with" dialogue box which appears when you try to open a link within an app on Android. You might be asked if you want to open a link with YouTube, or with Chrome, for example.
6. Power and charging:
Android M makes use of a new function known as Doze to improve device standby time. By using motion detectors, Android will recognize when devices haven’t been interacted with for a while, such as when a person is asleep or a device has been left on a table, to reduce background processes.Google tested two Nexus 9 devices, one running Lollipop and one running the Android M preview, and learned that M will provide up to two-times longer standby time. Even in Doze mode, your Android can still start alarms or notify you of priority notifications.
The Android M Developer Preview is available now for Nexus 5, Nexus 6, Nexus 9 and Nexus Player, and the final version is due to launch in Q3, 2015.
Well there's more features in Android M which includes Auto Backup and Restore for Apps, New app drawer, Android M RAM manager, Adoptable Storage Devices, Dark Theme, Google Now, Google Photos .
