Make sure you installed the special build a couple posts up.
Pair your bluetooth input device.
Go into Quakedroid
At this point I was able to use the DPad and LStick (A- and B-Buttons) for Menu Navigation.
Ingame the walk and look stick were working.
Then I went to options and to controller options and rebound all the necessary buttons.
My gamepad: Gamesir G3s, can recommend, really noice 

My setup:
R2: shoot
L2: jump
L1: last weapon
R1: next weapon
Had a blast playing, much more fun than touch. Don't get me wrong because I got along quite well with the touch controlls.

Sadly the Kindle still shows a white screen whilst playing the demo with sound. I'm looking forwards to the other graphics of Mark V coming to Quakedroid soon, or what I think I saw in the screenshot. :D 

"@gunter - aw that sucks. Sorry to hear that :( "

Heh, thanks.
Ya know, it really does suck! Hah, it's way more stressful than it should be when one of our little tech devices kills over.... But it served me well, daily, for the last 4 years. I think something in the hardware gave out, because factory resets do nothing.

In any case, I've found a nice little 7" RCA Voyager Pro Android 6 tablet on walmart.com for just under $50. Gets high reviews. And comes with a nice little keyboard case and free 2-day shipping, so I should be back up and testing Quakedroid in a couple days. 

@apm - Thanks! Always nice to have more interested parties. Like brassbite said, should work.

@brassbite - I only added controller support in that beta but I think I'll do another incremental and throw that in plus, if I am fortunate, a 2nd with what you correctly saw in a screenshot :D

@gunter - Awesome! That's funny that it comes with a keyboard too for under $50. 

I didn't have any luck with my Xbox 360 wired controller. (no buttons/axes had any effect). Here is the qconsole.log:
https://pastebin.com/94T2xJ1N

It doesn't look like it was even detected as a joystick? 

Hmmm. Does it show as a bluetooth device in Settings->Bluetooth?

I suspect it is not showing as a joystick to SDL, but in the next incremental I'll add a warning for devices that cannot be opened (I can't entirely rule this out, I'll have it print unopenable devices in the next incremental).

I posted a code block @ insideqc code that shows what it does when considering a device. Note it always prints something and didn't for your XBox 360 controller.

I have the number of buttons check to exclude the accelerometer.

By the way, should you ever be interested in compiling, it is rather straightforward and I'd be happy to assist. 

Download: GL QuakeDroid
Screenshots: Rubicon 2 Honey QMB Option

Suggested: if QuakeDroid has been loaded before ...

1) Settings->Video Options->Brightness: Texture Gamma
2) Settings->Preferences->Autoscale: Auto Large
3) (Option) If you want QMB particles Preferences->Effects: QMB

The above are new default settings but would be off in an existing config.cfg. 

It's a wired USB controller connected to a "USB->USB C on the go" adapter. I actually don't have any other games to test it with so I need to do some more testing on my end, and I'll try compiling myself this week and see what's happening. I'm worried that the SDL "Joystick" api won't be compatible across different joysticks. As I understand it, they added the "Game Controller" api's to SDL2 as a layer on top of the Joystick API to give a consistent view of joysticks, so when the API says "left stick" or "A button" etc., it's actually that stick or button on the joystick.

Whoah - GL support! Nice! 

Runs well for me, but can the GL error pop-ups during startup be suppressed please? At least for second and subsequent runs? Having to click through 4 or 5 of them every time gets old real fast. 

Whoa! I get zero GL errors during run, but I did the build in debug mode in the event someone had issues.

I'll suppress those in the next incremental and instead record them to log, but I want to know what they are. 

See the Butane qii4a post/link for an APK download for a different game with controller support.

Regarding the SDL2 joystick API ---

This is all new to me -- that being said, I looked at the SDL2 2.0.8 source code and it leverages native Android controller support which is extremely robust and standardized and mature.

So I am thinking the controller support is going to work almost universally.

Nonetheless, this is the thread where we find these things out ... 

I want to see more feedback, but the fact you have GL errors already annoys the hell out of me. I spent time studying the OpenGLES specs and was under the impression that it was pretty damn standardized.

/Pioneers, arrows in the back -- this is the whole purpose of exploring engine developing and killing these kinds of things, but damn ... 

Here's what I get; it's an el-cheapo Nokia 5 btw.

First is "Alert: GL_EXT_texture_filter_anisotropic" but no other info.

Then a 1280 at line 221 in GL_Evaluate_Renderer_CheckExtensions.

Then another 1280 at line 222, same function.

Then a 1280 at line 223.

Finally one more 1280 at line 224.

Following which it loads and runs fine. LIT files work, and VIS files also seem to do so; I have a bunch of them in a pak2.pak so I'm assuming it's getting them (I've deliberately avoided reading the code for feedback purposes). 

Alright, well -- gives me an action plan.

And I'll act on it and address in the next build. 

which is unfortunate because i really want to have quake (and all the expansions) on the go.

the controller can controll the phone in the moga pivot app so its not a bluetooth thing, the controller works, but does nothering in qd.

please could you suggest a controller which you think is best to use for quakedroid. (im willing to pay for a new one just for this project).

I dont think my moga hero can work with quakedroid, i sure cant get it to work. I dont even know if it works outside of moga pivot games, confusing.

If anyone does mange to get this working with a moga controller please let me know so i can know if its worth persisting with this controller.

Might be worth considering moga support for quakedroid, seeing as i think it's a popular controller? Let me know what you think. 

brassbite suggested a controller.

My controller, a ERO VR was $19.98 at Walmart. 

Make that EVO VR.

/Typo corrected 

You might try to see if your controller works with https://www.apkmonk.com/app/com.n0n3m4.QII4A/

When I was setting up my controller, the greatest initial difficulty was correctly pairing it with the device. I had to hit a certain combination of buttons to cause it pair as Android vs. pair as iPhone and my initial pairing was wrong.

I had to unpair the device entirely and then pair it again to get it to work right.

While the device was paired improperly, it still showed as a bluetooth device, but didn't work in any game.

@mh/GL_EXT_texture_filter_anisotropic glerrors and notification no longer happen. 

Cool.

Won't be able to test until 6+ hours time at the earliest (it's the warmest day of the year and I have seasides to walk along, beer to drink and pizza to eat!) 

warmest day of the year

It was literally like December at 7 am this morning in Ohio with light snow. I'm a "cold weather coder" so that actually is quite ok by me. 

Both Bluetooth and wired connections are fucked. HOWEVER, it's not QuakeDroid. There are 3rd party options to solve it but I'm not rooting my phone to play Quake or any other game.

I tried the Steam controller had a little bit of luck but the right pad acts as a mouse cursor. Sadly the orientation is for portrait and the mouse doesn't work as an input device for the software anyway.

Any suggestions would be appreciated. I'd like to buy a Steel Series controller for this but a bit gunshy at this point. 

This article may help you:

There was a dark time, long, long ago (six years or so), when Android was still a platform in its nascent stage, and to really unlock its best features, you had to root your device. Well no more. One of the many things you can do now without rooting is connect your PS4 controller to your Android phone or tablet via Bluetooth.

This is also this article:

Some reading/researching around ... you might look into trying to set HID mode.

HID refers to the gamepad protocol inherently supported in Android™ devices running 3.0 and higher.

Both my EVO VR gamepad and my external bluetooth keyboard use HID mode.


MOGA's Pivot app has yet to be updated for Android 5.0 compatibility

However, certain MOGA gamepads (not all) have a HID mode switch on them that let you use HID mode with games.

Thanks for the links. I've been able to pair the devices as shown in the links above. I believe the PS4 is defaulting to HID mode already as I can navigate the phone's UI as the guy showed in the video.

What happens is that I can use the X button IIRC on the controller and the analog sticks do work - which is a great start - but as soon as I press the other buttons the whole thing blows up. The view pans up and the QuakeDroid menu behaves as if the up button is held down.

I think re-configuring the buttons is probably the fix I need but the app you linked is out of date and unstable per the developer. I am going to keep searching and will report back.

There are other apk's that are out there that require rooting my phone to fix all this that I won't even bother with. I'll probably just get a different controller eventually. But I'm tantalizingly close on the Ps4 Dualshock.
