As written 3 times in this thread you need to test this library on a real device. It will not work on the emulator.

 

[junaidahmed]

Yes Erel,

I have test this library in real device also ............

Do you need any screenshot from real device ????

 

[Erel]

You need to post the logs from the real device.

yes

without posting the stack-trace we do not know either

It may be possible that the lib is not compatible with your device. The included native library is a few years old and is not maintained anymore.
You need to find another solution for you in this case. Using a pdf-reader on your device and let this reader show the pdf then for example.

Run your app in debug mode. If there are no logs then you will need to switch to USB debug mode instead of B4A-Bridge.

ok I understood "Run your app in debug mode",
but still I am unclear that "If there are no logs then you will need to switch to USB debug mode instead of B4A-Bridge"...

Pls advise.

There are two ways to connect to devices: B4A-Bridge and USB debug mode (ADB). See this tutorial: https://www.b4x.com/android/forum/threads/7978/#content

B4A-Bridge can only show the logs in debug mode. Some errors happen before the debugger can connect so it is only possible to see those errors in USB debug mode.
