The main activity loads settings essentially as soon as it
starts, in order to determine which tab to show. If the process
of stopping emulation has not finished at this point, a race
condition may be triggered where two IOS kernels are created
at once due to the emulation thread loading or saving the
SYSCONF while the GUI thread is loading the SYSCONF. To fix
this, we can wait for emulation to fully end before returning.
Because this race condition is hard to reproduce, I have not
been able to test that this actually fixes the race condition,
or even that the cause of the race condition is exactly what I
believe it is. But I am relatively confident.
The only place where initTouchPointer was called automatically
was Host_RequestRenderWindowSize, which is called at least once
after emulation start, but not after activity recreation.
I was hoping we would be able to pull in the default values
from C++, but it seems like more trouble than it's worth,
partially because of different settings having default values
of different types and partially because we don't have any
convenient way to get a list of all C++ settings.
Except controller settings, because those would be annoying
to fit into the same system, and I only need the non-controller
settings to be brought over for the next commits to work.
...instead of waiting for it after launching EmulationActivity.
We need this because there is code that runs very early in
EmulationActivity that accesses the settings.
Android TV devices aren't the only devices without touchscreens.
Regarding MotionAlertDialog, I could've replaced the leanback
check with a touchscreen check instead of just removing it,
but I thought there was no reason to prevent people with
touchscreens from doing a long back press if they want to.

We currently have one way of opening the menu on touch screen
devices (swiping down from the top of the screen to bring up the
action bar and selecting the menu in the action bar), and another
way of opening the menu on Android TV (pressing Back). However,
some devices that claim to support touch (or don't support
leanback? Dolphin currently conflates the two) don't actually let
you swipe down from the top of the screen in the way that Dolphin
expects, notably Chromebooks. There are also some phones where you
can swipe down from the top of the screen but this for some reason
doesn't lead to the action bar becoming visible, though we are
getting less reports about this nowadays than in the past.
This change makes us use the Back method on all devices,
since it should work on all devices with no significant drawbacks.
Unfortunately, we not only have two different ways of triggering
the menu but actually two entirely different menus, with the
non-touch menu not implementing options that only are revelant
when using a touch screen. A later commit will add the missing
features to the menu that we now use on all devices.
The reason why the finish() call was added no longer exists.
(Also, there was never a duplicate SettingsActivity as far as
I can tell, only a duplicate SettingsFragment.)
Just for maintainability. This is a shorter and more standard
solution compared to our current one where the Fragment
persists the Settings and passes it to the Activity.
That a device doesn't have a touchscreen doesn't necessarily mean
that it doesn't support rumble (though it is usually the case).
setPhoneVibrator already contains a check for whether the device
supports rumble, so we can simply remove the touchscreen check.
Since updating to 28 took us so long that Google Play started
requiring updates to target 28 before we actually merged the PR that
made us target 28, I'm trying to get the update to 29 done early.
Setting targetSdkVersion to 28 would normally force scoped storage
on us, which we do not support yet. However, we can easily
avoid this by setting android:requestLegacyExternalStorage="true".
There will be no such luxury with targetSdkVersion 30, however...
The functions with "UTF" in the name use "modified UTF-8" rather
than the standard UTF-8 which Dolphin uses, at least according
to Oracle's documentation, so it is incorrect for us to use them.
This change fixes the problem by converting between UTF-8 and
UTF-16 manually instead of letting JNI do it for us.
This essentially reverts d9c78d5. Thanks to the previous commit,
the touch controls issue which was fixed by d9c78d5 is still fixed.
The behavior for gamepads is reverted, bringing back the ability
to run diagonally in games that had trouble with it after d9c78d5.
Currently, the touch controller overlay uses a square gate for
sticks. This commit changes that so that it instead uses the
stick gate configured in the INI, which ensures that the values
sent to the core are appropriately scaled regardless of what
is configured in the INI and makes the overlay look nicer
if the INI is set to a stick gate that matches the graphics.
