Android Marshmallow Features for Developers 

Google unveiled its new version of Android  — code named Android M —  and like with Android Lollipop, we also got a developer preview. The Android M developer preview gave developers a clear timeline to test their apps, and an opportunity to explore the new features the latest version of Android has to offer. We now know this version of Android as Android 6.0 Marshmallow. Google has also finalized the Android version 23 APIs, and developers can download the official Android 6.0 SDK via the SDK Manager in Android Studio.Lets don't waste time dig into the pos

Android M App permissions

Application permissions have been completely overhauled in Android Marshmallow. Now you will be able to grant apps individual permissions to device functions, instead of the previous model of all or nothing.

What this means is, if an app is trying to access your phones camera or microphone, the system would prompt you saying this app is trying to access camera/ microphone on your device and it will ask, "Would you like to allow this?" It's a big change from the current system where you have to either give an app access to all the services it wants; or not install the app.

Here's another example: If you want to send a voice recording on WhatsApp, the system would give you a prompt telling you that WhatsApp is trying to access the microphone on your phone. This means you don't have to agree to permissions from an app which doesn't make sense to you, such as if you don't want a specific camera app to access your contact list.

Now you can also go into app settings and individually turn on or off app specific permissions at any time. This gives users complete control over an app, and resolves any privacy concerns they might have.

Android M Fingerprint Authentication 

Android Marshmallow brings official support of fingerprint authentication to the Android platform. To use this feature in your app, you will first need to add the USE_FINGERPRINT permission in your manifest. To authenticate users via fingerprint, scan using a device with a compatible fingerprint sensor, get an instance of the new android.hardware.fingerprint.FingerprintManager class and call the FingerprintManager.authenticate() method. You must also implement the user interface for the fingerprint authentication on your app, and use the standard Android fingerprint icon in your UI. This is to provide a uniform experience across the Android platform.

Android M Notifications Upgrade

Nothing major is coming to the notifications API this time around, but the Android notifications are getting a few upgrades. For one, there’s a new NotificationListenerService.INTERRUPTION_FILTER_ALARMS filter level that corresponds to the new Alarms only do not disturb mode. There is also a new Notification.CATEGORY_REMINDER category value that is used to distinguish user-scheduled reminders from other events (CATEGORY_EVENT) and alarms (CATEGORY_ALARM). Also coming to Android Marshmallow is a new android.graphics.drawable.Icon class which can be attached to your notifications via the Notification.Builder.setSmallIcon() and Notification.Builder.setLargeIcon() methods. Finally, there’s a new NotificationManager.getActiveNotifications() method that allows your apps to find out which of their notifications are currently alive.

Android M Bluetooth Stylus Support

Google has included improved support for Bluetooth styluses. Apps are now able to listen for stylus button presses and perform secondary actions by registering the new View.onContextClickListener and GestureDetector.onContextClickListener callbacks in their activities. The MotionEvent methods and constants can be used to detect stylus button interactions:

If the user touches a stylus with a button on the screen of your app, the getTooltype() method returns TOOL_TYPE_STYLUS.

Android M Bluetooth Low Energy Scanning

With low power Bluetooth Beacons getting increasingly popular, it makes a lot of sense that Android would evolve to better utilize the location context that they provide. The new android.bluetooth.le.ScanSettings.Builder.setCallbackType() ensures that your app is only notified when an advertisement packet matching the set ScanFilter is first found, and when it is not seen for a period of time. This approach to scanning is more power-efficient than what’s provided in the previous platform version.

Android M Video

Android Marshmallow offers a number of upgrades to the existing video processing APIs. The new android.media.MediaSync class helps applications synchronously render audio and video streams. The audio buffers are submitted asynchronously and are returned via a callback to avoid blocking the main UI thread. It also supports dynamic playback rate. Android Marshmallow also adds the new MediaDrm.EVENT_SESSION_RECLAIMED event, which indicates that a session opened by the app has been reclaimed by the resource manager.

Android M Audio

There have been a few incremental enhancements to audio processing in the new APIs, particularly focusing on support for the MIDI protocol with the new android.media.midi classes. Developers can now use these APIs to send and receive MIDI events. Android also adds new classes to create digital audio capture and playback objects. The AudioManager.getDevices() method lets you retrieve a list of all audio devices currently connected to the system. By registering an android.media.AudioDeviceCallback object, you can receive a callback when an audio device is connected or disconnected.

Android M Camera

The Camera2 API now supports both YUV and private opaque format image re-processing. Developers can decide if these reprocessing capabilities are available by calling the CameraManager.getCameraCharacteristics() method and checking for the REPROCESS_MAX_CAPTURE_STALL key. If a device supports reprocessing, you can create a reprocessable camera capture session by calling CameraDevice.createReprocessableCaptureSession(), and create requests for input buffer reprocessing. The ImageReader class now supports android.graphics.ImageFormat.PRIVATE format image streams, allowing apps to maintain a circular image queue of ImageReader output images, choose one or more images, and send them to the ImageWriter for camera reprocessing.

Android M Doze

One of the most common complaints faced by Android users has been unpredictable standby times on their phones. This happens because of apps running in the background, which can affect the standby time and performance.

Google is now looking to improve this with the feature called Doze. This is a new technology that learns over time and detects when your device is motionless and not being used, so it can be sent into a deep sleep mode. Once your phone is set to Doze, it checks for updates from apps less frequently, while still staying responsive for calls, messages, and other similar things. Google claims that internal tests have showed double the battery life on standby mode, when compared to Android 5.0.

Android M Automatic backup and restore

A seamless back up feature is something which has been missing from Android for years, and it looks like Google has finally taken notice. With Android 6.0, you can set up automatic backups, which will back up apps and app settings of up to your Google Drive storage. There will be a limit of 25MB per app, and the backups will not count against your Google Drive storage limits, and are encrypted by default.

These backups happen no more than once a day and run only when the device is idle and is connected to a working Wi-Fi connection to avoid unwanted data charges and battery drain on your device.

This way you can change phones or just reset your phone and when you re-install your apps the previous data will be restored conveniently. This feature works even with apps which have been side-loaded or purchased through other app stores.

These six features are some of the highlights, in our view. Overall, Google is bringing some much needed polish and great new features to the OS in Android 6.0 Marshmallow, and we can't wait to try it on the final release.
