Android Question Run pdf file

[abdo.b4a]

Dear All
I use this code to run "a.pdf" file stored in the device :
File.OpenInput(File.DirInternal, "a.pdf") , But it Does not work !
What is the wrong ? and what is the code to know if Acrobat Reader is already installed ?

Thanks very much

File.OpenInput has nothing to do with "running" a file.

Search for FileProvider and see how the image is displayed with the default viewer app.
