Run my app at opening of a file of determinate extension android

Question

i'm developing an android app, this app generate text files that contains a Json string, the files are saved using .fr extension. What i want is that when the user open a file with .fr extension the system run my app. I read other similar questions in stack and i add an intent filter in my manifest.xml, but it don't run. If i try to open a file with fr extension android don't show my app in the list. I try to make this with txt file, is the same problem. I ask you why it don't run and if i will fix the problem how can i read the file. thanks.

What do you mean by 'open the file' ? Also note that a simple text file with an extension of '.fr' will not match your intent-filter of 'application/fr' - you probably don't want to use mime-type.
