Platform(s) for real-time automotive GUI

(((I have decades of real-time and GUI development experience, but am relatively new to Android.)))

I will be hiring out the development of an Android automotive app for use in race cars. In essence, it replaces the dash. So it needs responsive and nice looking automotive style gauges in the GUI, and it needs an architecture that can properly handle the real-time data coming in via USB.

I'm asking on this forum for suggestions of:
1) open source tools and platforms that can make app development faster and more robust, and
2) methods and techniques to further assist.

Be aware that this app MUST run on the following hardware: Teclast P80H. Android 7.0. Security Patch Level January 5, 2018. Kernel version 3.18.35. Build number V1.04_20180201. CPU Modem MT8163. CPU Kernel number 4. 1GB Ram. 8GB Flash.

If you've had DIRECT experience in the design/use of circular and other shaped GUI gauges suitable for automotive, please let me know your recommendations. If you have SPECIFIC knowledge of one or more solutions, even without direct experience, please make suggestions. Please note that this opinion may change over time, but for now, I'm not interested in any paid third party solutions... only open source solutions.

If you've had DIRECT experience in real-time apps on Android, handling data or video information passing and so forth, please let me know your recommendations. If you have SPECIFIC knowledge of one or more solutions, even without direct experience, please make suggestions. I've been looking into RTOS versions of Android, but I'm not yet sure if one is actually needed in my case or if my selected hardware can support one.

Your input is GREATLY appreciated.

How to set the height of view to be the same as another view?

Hello, I'm begginer. In relative layout on image view which is aligned to the bottom of parent (relative layout) I want to put a button which would have height the same as image view. How can I do that? I can't make button to be child of image view. If I could, I'd do match_parent. I read that I can use frame layout to put view on view but I can't bottom align view when using it. Using Android Studio.

Imaging

Hi all,

I am new to Android Development. I have been looking at how to create a Bluetooth app to communicate with my Arduino and I have picked up a better understanding. My problem is now a little different and I am not sure where to start. I read in data and from my Arduino and I store it in an 2Darray in 128x128. I would like to should this image on the app. Convert each data to its corresponding color. For example if Array[0][0] were 5 I would like that pixel to be red and if it were 0 blue. Then I need to be able to display that changing image every time a new set of 128x128 information is read. Can anyone please point me in the direction I should be looking?


thank you.

Dead but still touch responsive screen on Galaxy Tab A 10.1

Hello everybody

I have a Galaxy Tab A 10.1, specifically the SM-P585 model with S Pen. The thing is that a few days ago the screen died. However, althought it's completely black and not showing any image, it's still responsive to touch. I can notice that because I am able to do things such as activate or deactivate the Wi-Fi by touching the screen in the place where the Wi-Fi icon should be.

Considering that it's likely that just the display part of the screen is not working, while the touch responsiveness seems to be fine, what kind of damage it could be? Do you think it could be bad enough to need to replace the whole screen, or could be just a connector issue?

Also, for example, when connecting the tablet to my Windows computer, the computer makes the corresponding sounds when connecting or disconnecting some peripheral, so the tablet is pretty much alive despite the display issues. I think that someone accidentally might have sit over the tablet, but it doesn't seem to have any kind of external damage, and also it's protected by a screen protector and a hard case.

Is there any internal connector that has to do only with the display part of the screen, but not with the touch responsiveness?

Thanks!

When is GCam 7 coming officially to Pixel 3XL?

Since both P4 and P3 have the same sensor, I think there won't be any dramatic difference between the two once the GCam 7 is "officially" available to the Pixel 3s. Btw, I have ported GCam 7.2 to my 3XL and I actually prefer the native GCam 6 on my 3XL. That's why I kept on saying "officially" because I think there's a difference when the GCam is updated to 7.2 from Google Play versus an APK download.

Help Battery % is different when on or off

Ive got an Axon 7 that shuts down at 15%, when I plug the charger in itll be something like 54% and when I turn it on the battery might be something totally different. Last nightafter it closed itself down I charged it to 100% while it was off, switched it on and it was at 100%. I watched a couple of videos, then closed all apps and turned wifi & mobile data off and it dropped to 2%. There it stayed until 11pm that night, I moved some files from phone to sd card and it lost power. I plugged it in and it was reading 34% while it was off. Can someone tell me whats going on, is the battery knackered or is it just out of sync?

Help Bluettoth OK for calls, but not for music in my 2007 Audi

Hi I am a newbie in your forum.

I used to be able to make calls and also play Spotify music from my S9 over Bluetooth, in my 2007 Audi.

Since my Audi's MMI was recently updated at the dealer, the phone was automatically paired, but I can only make calls but cannot play music.

I've removed and reconnected Bluetooth connection from both ends, have reset the car Bluetooth to default settings and have tried various settings on the phone, such as various Bluetooth settings, the Samsung Smart things app settings etc etc.

Again, only calls, no music

Currently on my phone, in Settings/Connections/Bluetooth/Paired Devices, i see my Audi properly paired, but under 'Use For' I only find Calls and Contact access, nothing for music there.

Any help will be greatly appreciated!
