Android App folder filesystem access

My question is related to filesystem access开发者_如何转开发 in Android apps. Suppose I want to grab a file that another app just downloaded? Can I access the other apps file / doc-folder from within my ohwn app? My first guess is no...

Thanks for clarification ;-)

If that other app is downloading the file to the sdcard, and your application has permission to access the sdcard, then yes, you can grab the file.

But if the other apps downloading to the internal filesystem, it will not be possible to get the file, unless the other app is allowing your app to do so, by using permissions or intents.
