The Android M developer preview was recently launched at Google I/O 2015 in San Francisco. At the conference, Google senior VP of Products Sundar Pichai said that the company had “gone back to basics” with this new version of Android. 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

In the previous version of Android M , we have to accept some list of app permission before to install the application into our phone. Things are changed from the new M release. Here the permissions will now be requested the first time we try to use a feature, not at the point of installation. “We don’t have to agree to permissions that don’t make sense”.

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. Fingerprint support

The very good next step taken by Google is to giving the M release with a fingerprint support. We can do play store purchases and  unlock the device using the fingerprint. Google is opening the necessary APIs to allow developers to add fingerprint support with any app. And the  bio-metric authentication will also be extended to Android Pay to authorize payments, making it work a lot like Apple Pay.

3. Android Pay

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. It can be compatible with any device with  NFC capabilities (and running 4.4 KitKat or above). The user can tap over the NFC panel to pay for products.

4. Power Management

Its Doze actually. the new power management mechanism for Android M devices.

Doze that recognize when the Android device is in a rested state to help conserve power. Google says it has tested it with a Nexus 9 and claims it can help make battery life last two times longer in standby mode by using fewer background services.

5. USB TYPE-C

Android M will bring full support for Type C, which should be capable of fast data transfer and fast charging. Apple has already announced support for the next generation USB standard on its latest MacBook earlier this year, while the new Chromebook Pixel also includes support.
