### Misc
## Private APIs used / Assumptions for Android customizations
This app doesn't require Busybox, but if you have installed it, please make sure it's v1.28.1 or higher.
_a.k.a. things that can go wrong if this app doesn't work._
This is a list of stuff that might impact this app's functionality if unavailable.
This is only meant to be an index. You can read more in the source code.
API light grey list:

* (deprecated since API 26) [`Landroid/net/wifi/WifiManager;->setWifiApEnabled(Landroid/net/wifi/WifiConfiguration;Z)Z`](https://android.googlesource.com/platform/prebuilts/runtime/+/94fec32/appcompat/hiddenapi-dark-greylist.txt#4378)

Private system configurations:
* `@android:array/config_tether_usb_regexs`
* `@android:array/config_tether_wifi_regexs`
* `@android:array/config_tether_wimax_regexs`
* `@android:array/config_tether_bluetooth_regexs`
Other:
* Activity `com.android.settings/.Settings$TetherSettingsActivity` is assumed to be exported;
* Several constants in `ConnectivityManager` is assumed to be defined as in `TetheringManager.kt`;
* `android.net.conn.TETHER_STATE_CHANGED` is assumed to be a sticky broadcast.
For `ip rule` priorities, `RULE_PRIORITY_TETHERING` is assumed to be 18000.
Undocumented system binaries are all bundled and executable:
* Since API 24: `iptables-save`;
* `echo`;
* `ip` (`link monitor neigh rule` with proper output format);
* `iptables` (with correct version corresponding to API level);
* `su` (needs to support `-c` argument).
If some of these are unavailable, you can alternatively install a recent version (v1.28.1 or higher) of Busybox.
Wi-Fi driver `wpa_supplicant`:
* It should be [fairly recent](https://android.googlesource.com/platform/external/wpa_supplicant_8/+/216983bceec7c450951e2fbcd076b5c75d432e57%5E%21/); (see also [#31](https://github.com/Mygod/VPNHotspot/issues/31))
* `/data/misc/wifi/p2p_supplicant.conf` is assumed to be saved to and have reasonable format;
* Android system is expected to restart `wpa_supplicant` after it crashes.
