Here's the error on the Zebra device TC when using A13 and A14:

java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission for android.content.AttributionSource@f787829e: AdapterService getConnectionState

No problem with Google Pixel and any version

 

Manifest permissions:

   <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
   <uses-permission android:name="android.permission.BLUETOOTH" />
   <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

Hi John. Thanks for using Zebra products. 

If you can, please explain briefly what you were trying to do when the error occurred. 

Several Zebra apps require the device user to manually grant certain permissions before normal operations are possible. 

Thanks,

Hi. My apologies please for the insufficient information. This is a Bluetooth printing application, the framework of which I've used since before an SDK was available. The error is logged on socket.connect(). An AS example project here: https://zebra-my.sharepoint.com/:u:/p/qkjn37/EVZxBP258XRKuQu_mJbR5g8B_XneSkg3mX8q1RFIDmm5KA?e=72RABA

Hi John,

As per Android developer guide, "android.permission.BLUETOOTH_CONNECT" is added from A12 as dangerous permissions and these are runtime permissions and needs to be handled by following below link.

Thanks Sandeep. I'm aware of the runtime permissions but I'm confused why my app runs without error on the Pixel. I lowered the minSdkVersion to 16 and no longer get the error on the TC so I'm good. My only concern now is if this is a TC problem or a Pixel problem. If it got me it'll get others.
