Can't open obb file although it is there

Question

I'm trying to mount an obb file but

std::fstream test("/storage/emulated/0/Android/obb/com.bixense.jngl_test/main.1.com.bixense.jngl_test.obb");
assert(test);

says it doesn't exist (or I can't access it). When looking via adb shell the file is located here:

/storage/sdcard1/Android/obb/com.bixense.jngl_test/main.1.com.bixense.jngl_test.obb

Do I need to give my app some special permission?

project.properties has target=android-20, so I guess 20? There's APP_PLATFORM := android-10 in my Application.mk file though. — jhasse, Sep 03 '15 at 13:50

I would try to access it in good old C style and print strerror(errno) as in https://stackoverflow.com/a/504039/755804

Thanks! This gives me "No such file or directory" though :( – jhasse Sep 03 '15 at 17:08
Ah wait: It's "Permission denied". So I'll have to add some permission to my app, right? – jhasse Sep 03 '15 at 17:09

Okay I've fixed it using

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

in my AndroidManifest.xml. Strange, I thought I've read that this isn't needed for accessing my own files ...
