# Android

Here is a summary of the changes, fixes, and additions in IMS SDK release 1.13:

### Breaking Changes

* **The version 1.10 BluetoothManager is no longer available.**\
  Use [device manager](https://github.com/ims-developers/android-sdk#device-support); the combination of `BluetoothPairedAclProvider` and `DsDeviceDetectionMonitor` provides the same functionality.

### New Features

* Primary users can send invitations to secondary users also based on their family accounts (VEHICLE and ACCOUNT based invitations).
* Primary users can remove secondary users from their FAMILY ACCOUNT.

### Known Issues

* SDK 1.12 is not obfuscated. If you are using SDK Bluetooth (Device) libraries, you need to add this line in your proguard-rules file : `-keep class com.drivesync.android.devices.** { *; }`
* See [Fixing Runtime Crashes](https://github.com/ims-developers/android-sdk#fixing-runtime-crashes)
