Save Controller Profile does not work on Android by default

[davidhedlund]

Description

In the default RetroArch configuration file (retroarch.cfg), the joypad autoconfig directory is set to "/data/user/0/com.retroarch/autoconfig" which requires a rooted Android phone. Most Android phones are not rooted. Due to this setting, RetroArch is unable to write files to this directory.

I just added this temporary workaround for Android in our Joypad Auto Configuration guide: https://docs.libretro.com/guides/controller-autoconfiguration/#android-configuration

Expected behavior

This improvement streamlines the process for users, eliminating the need to follow the Android section in our Joypad Auto Configuration guide (https://docs.libretro.com/guides/controller-autoconfiguration/#android-configuration) in order to generate autoconfig files for Android users.

Update configuration file

The current default retroarch.cfg contains:

joypad_autoconfig_dir = "/data/user/0/com.retroarch/autoconfig"

I propose that we replace the default joypad autoconfig directory path with a user-accessible location:

joypad_autoconfig_dir = "/storage/emulated/0/RetroArch/autoconfig"

Autoconfig file migration

To ensure independence of the Update Controller Profiles option for the controllers to work by default, I suggest that RetroArch automatically copying the system autoconfig files from /data/user/0/com.retroarch/autoconfig to the newly designated user directory /storage/emulated/0/RetroArch/autoconfig directory.

Actual behavior

"Error saving controller profile."

The joypad autoconfig file is not generated.

Steps to reproduce the bug

• Settings > Input > Retropad Binds > Port 1 Controls:
• Set All Controls
