Android Question Bluetooth Printer Connection Problem on Release(obfuscated) Version

Richard Goh · Jun 2, 2016

Hi,

I discovered that there is a connection problem to Bluetooth printer when compile the apps into Release (obfuscated) version. It's can't connect to the printer. It's was keep trying to connect to the Bluetooth printer. But it's working well when compile in debug or Release version without obfuscated. Any advice on this?

Thank you.

Moved to the questions forum.

You need to post the relevant code. Make sure to go over the common pitfalls related to obfuscation: https://www.b4x.com/android/forum/threads/android-code-obfuscation.13773/#content

Hi Erel,
Sorry for late reply. I had re-test the programs attached is the printing sample programs which have the connection problem after compile into obsfucated mode.
Thank you.

Did you go over the pitfalls section in the tutorial? The error is clear.

You are calling a sub with this code:

B4X:

CallSub2(BTNotify, BTNotifyRoutine, BTConnected)

The value of BTNotifyRoutine ("PrinterConnected") should include an underscore.
