Filesystem access on android

Filesystem access on android

When writing an android app using allegro (NDK), i need to be able to write to the actual filesystem. I know that I can use al_android_set_apk_file_interface() and al_android_set_apk_fs_interface() to set the filesystem to the apk, but I need to be able to write to the actual filesystem to save my config files and to read user themes.

When trying to use al_path_cstr() on android without setting the apk file interface, the program segfaults.

How does one access the main/external flash?

Does your program request, and have, permission to access the file system?

al_set_standard_file_interface otherwise to switch back

Nope it's returning nulls when I try and do anything with the "normal" filesystem. When I try and get a path, it segfaults

Here's my test program

I got it never mind

Please share the solution. How do you access the filesystem on Android?

I see, test_path was NULL.

Yea, I wasn't assigning test_path to anything. It's really tough to get meaningful errors out of an Android app. I use stdout/stderr to log my debug messages, and those are piped to /dev/null on the platform

Also it looks like the android version of allegro deson't support Android Video.
