You said in patron the app work in lollipop as minimum target and some medium devices and yeah hell
It run only on snapdragon latest release and android.
can it be for medium devices in future? ???

One of the things I immediately noticed on installing the app is that there's no way to disable game audio

Noted, I have a volume slider that didn't make it into the final app

Originally posted by @BreadFish64 in #12 (comment)

It also requires an audio enable/disable switch so that the audio doesn't take up any processing resources if turned off hence slightly enhancing the game's video rendering.

In some circumstances the frame counter can display extremely inaccurate values on Android. I'm just opening this issue to keep track of this bug.

Morph reported this happening in Super Mario 3D Land for example.

I'd like to compare it to NDS Boy if you don't mind. It has this feature that makes playing more convenient, especially for those who use their own controller with Citra. In this example, the button is called "touch" and it basically toggles showing of the buttons on the screen. It would be awesome to see something similar in Citra.

The images are too big even after resizing, so I've put them in spoilers (further downscaling of those images result in visible compression artefacts).

EDIT: Might be related to #39.

Tales of abyss is working but the screen is all black only sounds plss fix it bec. I always want to play that game.. thanks you so much u bring citra on android.

Lighting flickers every second frame or so on Exynos 9810.(is probably an issue with Mali GPU)

I don't know where logs are saved in mobile version, and there's no citra_log.txt in my /sdcard.

The issue is visible on attached screenshots.

edit: So apparently there are logs on mobile version, but I don't know where they are. Please help.

When Citra is minimized the audio channel continues to be open. There is a slight hum. The audio should be cut off completely when the app is minimized. When I open recents and swipe away Citra (closing it), the hum goes away. This is more easily detected when using headphones.

In beyond the labyrinth if you are using an English patch for the game the party members names wont pop up except for your own so you dont know who is talking.

The GitHub APK is a single package, while the Google Play version gets installed as split apks:

These files are from /data/app/org.citra.citra_emu

base.apk (2.67MB)
split_config.arm64_v8a.apk (26.30MB)
split_config.en.apk (30KB)
split_config.xxhdpi.apk (540KB)

The last 2 (or 3) are device/region specific.

Since the GitHub APK is a single file, this makes the two versions incompatible with each other. You simply get a "App could not be installed" error when installing the GitHub APK while the play store version is already installed. You can't do it the opposite way because Google Play will not update an app installed from outside.

By "incompatible", I mean that the two apps can NOT be installed at the same time as they have identical package name, but still the GitHub version can NOT be installed as an update to play store version.

This is reported on Android 9 but should be the same for any version, as it's most likely related to Google Play app publishing.

Hello sir..
Iam use phone with chipset helio G90t and game is very lag.
Will it take a long time for the Citra Android to support chipsets other than Snapdragon?
Thanks in advance.

This happens for example when I use the translucent controls on my Galaxy S8+.
The control bar just doesn't appear when sliding down from the top then.

I'll try to find a workaround for this in the future.

Save states would be awesome!

Hi, I'm curious how you guys reconcile using the Android Billing library (which is closed source, and gets included in the APK) with the GPL.

This part of the FAQ seems to preclude using it: http://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL - "You may not distribute these libraries in compiled DLL form with the program".

But if that does not apply somehow, which I assume since you are indeed using it, I'd be curious to know the reasoning - always good to understand the GPL better.

When playing Pokemon moon the game works fine at 60% of speed, but it randomly freezes, music keeps playing but everything else doesn't works.
In Pokemon Omega Ruby the game works between 80/100% of speed, but the game crashes in the title screen, cutscenes, and Pokemon selection screen when hardware shader option is enabled, when disabled the game doesn't crash in that instances, but runs at 40% of speed and it randomly freezes, just like in Pokemon moon
In Pokemon X the game crashes when hardware shader is enabled.

Implement a way to be able to play our games stored on networked folders

The game starts without any issues, but it crashes when loading the "game field" to play on. Practice mode from intermission works without any issues (it skips the "game field"). Please see the video.

I'm seeing the app version "null" in the Play Store. Why is that? Can you fix the versioning to be correct please?

Plss add Android Nougat compatibility because I have a snapdragon 625 processor and I can't update my software 😢

And I see, you already closed the issue same to my problem

There's any reason why you can't change your miminum Android version?! It's okay if doesn't good we will accept that, but we'll wish that we can also play some 3ds games so bad 🙏😢🙇

The original shin megami tensei 4 will crash the citra app back to the game selection screen when loading a save file

I think I've seen someone port this on Discord as well but didn't find any open issues about this kind of crash, so I thought I'd just post it here.
In Pokémon Ultra Sun (might apply to Sun, Moon and Ultra Moon as well) there's a crash occurring when the submenu is opened (Mystery Gift / Live Competition) instead of continuing the adventure. After leaving one of the game's submenus, the title screen with animation should appear again as it is on my 3DS and on Citra Desktop. Instead, the game immediately crashes. The video showcasing the issue is here.

I'm not sure if that's related to my phone specs at all, but I'll post them here along with the log.

On Picross 3D Round 2, you have to hold down different buttons and touch things on the touchscreen to perform different actions (eg. hold X and touch a block to remove it, hold Y and touch block to paint blue).

This works fine on Windows but doesn't immediately work on Android when using the virtual gamepad. When I press and hold a button on the virtual gamepad, the touchscreen doesn't register any presses. This occurs with any button on the virtual gamepad, regardless of whether it is overlying the screen or off screen in empty space. Swapping screens or changing layouts doesn't make a difference either.

A workaround is to press and hold on the touchscreen, then press and hold the gamepad button, then release the touchscreen while still holding down on the gamepad. Any subsequent touches on the touchscreen then register properly.

I'm on beta 2 of the official Android build, though also had this issue on the initial beta release.

The GitHub release APK (Beta 2) does not allow for premium purchase.

Feature request: add (optional) on screen toggle button for "Enable Speed Limit." This would allow for quick access to "fast forward."

Dragon Quest VII (DQ7) will not open if "Enable asynchronous GPU emulation" is checked. If the option is uncheced, then it will start. Once the game starts, I am able to go into settings and check the option.

When trying to take photos in dragon quest 8 the photos will save as a completely black picture as if nothing was taken meaning that you will not be able to get past cameron obscure when you first encounter him and in turn making the game not passable past the 3rd town

Version (commit hash) of Citra:
*Initial Beta release (May 22)
*Android Build 3: QQ3A.200605.001
*Pixel 3

Steps to reproduce:

1. Enable hardware rendering (on by default)
2. Load captain toad
3. Loads initial screen
4. Fades out initial screen and then returns to Citra's game list

Note: If I disable hardware rendering it will render Toad's face in a circle (but with incorrect colors).

Additional info
Changing other debug options doesn't help (disable JIT/hardware shading)

Logs don't have any info about the crash. They just complain about the encryption being incorrect (I converted it with godmode9).

Citra Android doesn't handle notched phones correctly, resulting in weird cropping or wrong screen dimensions.
Using Googles APIs, we should detect notches and work around those problems.

From a users perspective, I want to be able to edit and select cheat files from within the Citra UI. Functionality-wise it should be just as complete as the Desktop version.

Considering a mod is aware of this I just thought I'd leave it on the repo too, it crashes the application upon launching a title on the Android Switch port

One of the things I immediately noticed on installing the app is that there's no way to disable game audio which also stutters in game because game speed rarely reaches over 85% on a Snapdragon 845 phone, would be great to see more optimization done on the graphics like the Citra emulator by Zhang Wei, which also incidentally has a cheats section for AR codes which works beautifully in game, hope you address these issues and also have a way to move/position the upper and lower screens and edit screen size if possible because the lower screen looks overly magnified and pixelated in comparison to the upper screen. Lastly I'd also request to add AR cheats if possible, Citra is beautiful on the PC because of it.
I've added a screenshot of both Citra apps side by side.

Thanks and regards,
Alwyn.

The same bug that affects this game from starting on the desktop version also affects the android version.

I would assume you'd have to add the CPU clock speed feature to get it working again

I'd like to be able to install CIAs from the UI, just as on the Desktop version.
One problem on Android is disk size constraints though.

In a future update, can the devs please add the cheats option.

Running at 1x resolution the game creates a flickering mishmash of pixels on the screen
At 2x and higher mgs shows a similar problem with a diagonal line from bottom left to upper right
Also the game runs significantly slower than citra mmj

It would be nice to be able to change the controller opacity / transparency, especially when in landscape.

I don't know of this is planned in a future update or not, so I thought I'd open an issue or a "feature request" for it.
So I was wondering if you could implement a menu with Citra Desktop's options that appears when you right click a game in the game list (save data location, custom textures, update/extra data location etc.)
However on mobile you can't right click, so instead we could open this menu by pressing and holding a game in the game list. This would especially make it easier for users who need to transfer their save data from Desktop <-> Android.
I know your goal is to achieve feature parity with Desktop, so feel free to close if you don't think this request is needed!

This issue can be reproduced with Async GPU both enabled and disabled.
To have it happen, the best way is to start a new save, play until level 2 of World 1 and go into a pipe there.

This will cause the music to continue playing while our button overlay and the gameplay is completely frozen. When trying to press the back button, the app crashes immediately.

I'll try to get a log and a call stack soon.

We are currently not decrypting any Amiibo contents anyway, so I think a feature like this would be possible to implement and a nice addition.

Please fix this problem , mhxx mh4u crashes after loading when opened with citra official emu for android . This happened to many player n w hope in the future this game not crashes anymore

Samsung S9 works perfectly fine.. FPS is 60 for Super Mario Land 3D and Zelda Between Two Worlds. THANK YOU DEV!!

However.. I have a problem and I want to test it on Android TV so I can report to you.

I installed it using the third party and it tried to install but message said: App not installed.

Mali GPU are getting poor performance in Citra, is there any way to tweak the code for better framerates? Even top Exynos phones can barely run Pokemon games, while 835 is doing fine.

Synthetic FLOPS tests are reporting Mali's superior performance, but the emulator is proving the opposite.

Is there anything we can do at this stage?

PS: I believe this doesn't need any logs because it's performance issue.

Google has already shown that Kotlin is its preferred language for Android now.
It also has better static analysis, null safety, is used by major companies, etc.
It can also be picked up easily by people knowing Java and Android Studio provides automatic seamless code translation.

Any feedback on this idea would be appreciated.

If screen segmentation is not possible

this official citra

this mmj unofficial

Thank you always for your hard work.
