Hello fellow automotive friend

did you use an off the shelf dev kit, some proprietary OEM part from Harman/Conti/whoever, or some sort of reference board from, say, Nvidia?

we got some piece of poo poo chinesium head unit from amazon, lemme see if i can find it

e; oh that was easier than i thought: https://www.amazon.com/gp/slredirec...dgetName=sp_atf

idk how exactly they flashed it but it worked

Dumb question, but could you ask the OEM what arguments to use when calling the emulator tool from the command line? If they insist it works, they've got to have a way to do it (though it might be specific to some jerkwad engineer)

in my experience if you're dealing with the OEM they use the physical unit to do testing and don't bother with an emulator of any sort.

Sure, I guess I misread the original message. I read into it that they put out an image specifically with emulator support, but rereading shows that's not necessarily the case

It does, but depending on how straightforward your native code setup is it can be difficult to get running. If you're writing and building all the code with AS it should work without much headache.

Is anyone else running into a bizarre issue where the layout editor in AndroidStudio shuffles everything in a layout whenever you modify something? Like even renaming a layout causes everything in it to sort themselves by their class. It's so bizarre, and also super annoying.

Edit: It also likes to refactor component names across files even when I say not to do that. I renamed deleteButton to deleteGroupButton and it asked if I wanted to refactor - "No (local only)". Build fails - it renamed all deleteButtons in every layout.

Does anyone know how to get the boot animation to display in landscape mode rather than portrait (for an AOSP build, Android 9)?

Our device is always in landscape mode -except- for the boot animation for some reason. It displays in portrait and when it is done the screen rotates to landscape. The image is made for landscape so it looks terrible.

Maybe, but you're looking at boot code at that point. Rotating really is going to be your best bet unless you feel like Going On An Adventure.

A few comments.

Play store still shows a "Not designed for children" warning. For utility apps there's no reason you should be restricting this.

Don't disable the back button.

DON'T DISABLE THE BACK BUTTON.

Follow the guidance on how to prompt users for permissions; don't let the permissions dialog be the first thing they see.

Give me a good reason why you need the full storage permission instead of app local storage or selecting photos via intent. For that matter, consider saving to a location that camera apps are aware of.

"Torch" is a British word for flashlight, consider localizing.

Guide dialog still shows in portrait even when holding on landscape

I could be wrong but I think there's a lengthy review process and stringent requirements to be designed for children now. I tried it on my cartoony live wallpaper and it got rejected / still has that notice.

I limit the preview size to maximize the frame-rate. I am using OpenCV4Android in order to interface with the camera api and perform native image processing. I don't know if using the camera api directly would appreciably improve performance, but I'm not sure how to tell without doing a huge revision.

I'm trying to give my app an option to pick the language, but it's proving to be a lot more difficult than I thought.

code:

Activity context = getActivity();
Locale locale = new Locale(languageToLoad);
Locale.setDefault(locale);

Configuration configuration = context.getResources().getConfiguration();
configuration.setLocale(locale);

//context.createConfigurationContext(configuration); // This does not seem to do anything

//context.getResources().updateConfiguration(configuration, context.getResources().getDisplayMetrics()); // This works, but is "depreciated"

context.recreate();

I'm also running into the issue that recreating the Activity breaks everything. The fragment doing the language setting is sitting in a ViewPager, and when the Activity gets remade, the ViewPager gets set to null, so when I change the page with a button, it crashes. It also does an annoying double blink thing while it's reloading, and only actually sets the language on the second time I set the language.

Is there a better way to do this?

Googling the problem gives me a lot of results how to change my phone settings. It's annoying sometimes that the language and the OS have the same name.

The android way is to just let the OS decide the language but I've done this for testing purposes (API 24+ only):

code:

/**
 * to change language in activity:
override fun attachBaseContext(newBase: Context?) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N && newBase != null) {
super.attachBaseContext(MyContextWrapper.wrap(newBase, Locale("fi")))
return
}
super.attachBaseContext(newBase)
}
 */

class MyContextWrapper(base: Context) : ContextWrapper(base) {
    companion object {
        @RequiresApi(Build.VERSION_CODES.N)
        fun wrap(context: Context, newLocale: Locale): MyContextWrapper {
            context.resources.configuration.setLocale(newLocale)
            val localeList = LocaleList(newLocale)
            LocaleList.setDefault(localeList)
            context.resources.configuration.setLocales(localeList)
            val ret = context.createConfigurationContext(context.resources.configuration)
            return MyContextWrapper(ret)
        }
    }
}

As above, you generally want to just let the language the user has chosen for their device be used. Is there a reason you want to let the user override it?

I've lived in a lot of places and have had to deal with a lot of computers which aren't in my native tongue, and it's super frustrating when you have no option to change the language on something. I recognize that sharing a phone is tremendously unlikely, but why not give users the option?

Like this ^
You never know what kind of relationship the user has with a language. I meet a lot of people who have their phone in language X, but like to have something like Facebook in English for studying purposes.

Also the app is for myself, so I'm not super concerned about "best practice", haha.

Cool camera effects. The UI isn't very intuitive and the guide could be more helpful but if it's just for you to use that stuff isn't so important.

Is it possible to build Android with OEM unlocking enabled and dm-verity disabled by default? That does not involve hacking the uboot source and figuring out whatever magic the OEM unlocking service does? Or is it vendor specific?
