You need to test it on a real device as it uses a native library and probably doesn't include the x86 binary.

I have test in "Real Device" also.but its show an error message as "Unfortunately ,B4A pdfviewer has stopped"

Please help erel...

where it is problem ????

Start with posting the log from the real device... Without errorlog it is hard to give advices.
Which Device are you using? What Android Version does the device have?

Please check my below Config...

Device - Samsung Galaxy Note with Model "SM-N910C"
Android - 6.0.1
API Version - 25

Which library are you using exactly? Where did you get the library? URL

Please check below link ,that I have used in my application

It does NOT WORK on the Emulator as the emulator is based on x86! The lib does not include a binary for x86 architecture

Use a REAL Android-Device.

Sorry once again

I am getting the same error in device "Unfortunately ,B4A pdfviewer has stopped"....

Please download apk from below link

Whether I need to install any third party software in Real Device ????

It is working on my device.
