I am starting to get used to Android DJI Mobile SKD... Even successfully got DJI FPV sample code running on my Phantom 4 Pro+ GL300E screen (SDK 22).
My problem: it seems that an app using the SDK has to get the internet connection to be able to register to DJI before doing anything.
Such process apparently doesn't happen only once, but occurs every time I run my application.
My need: I should be able to use my UAV in the countryside, without any internet connection of course: will I be able to use a DJI-SDK based application in such conditions?
You only need to register the SDK once via internet. After the first successful registration, the app remembers it and you can use your app on offline mode. You will however need to activate it again if you make a clean installation.
Btw:
You don't need to have a SIM inserted to use your App.
You don't need to login to your DJI account to use your App.
The SDK seems to connect to the internet on it's own from time to time. The purpose is unknown to me but I guess it's e.g. to retrieve updates for the flySafe Database (FlyZoneManager).
To ensure the SDK does not connect to the internet apart from app activation you can additionally use the LocalDataManager (LDMManager) accessible from the DJISDKManager:
if(DJISDKManager.getInstance().getLDMManager().isLDMSupported()) {
DJISDKManager.getInstance().getLDMManager().enableLDM();
}

Currently,
My team and I are developping an Android Auto enabled app. And it appears to me this app is only available in my car unit, when I enable unknown sources in the Android Auto app.
However I'm wondering what defines an unknown source and how do I make sure my app is not an unknown source. Does Android Auto communicate with the Google Play Services for this or do i need to sign the APK with specific data?
How are you deploying your app? If you are deploying with Android Studio: as I recall you won't see it on your real automotive head unit, just the emulator. To show on the head unit it needs to be deployed in the Play Store, at least in developer and pre-release mode while under development.
First of all: Android Auto runs on your own device, meaning it adapts the same permissions you granted to particular apps. If your app doesn't have an app in the normal UI or you didn't open it on your phone once, then it would usually prompt you to grant permissions the first time you open it.
An unknown source is pretty much any way of getting your app outside of the Google Play Store (and OEM-specific app stores like Samsung App Store for Samsung devices etc.).
That is especially common if you e.g. download an .apk from the internet and want to install it, but your phone thinks their own file manager is an unknown source (because it is not intended to download apps).

I can attach my Android phone by cable, and install to it. I can run "Local Machine" on my windows 10 development machine and test there. I want to give a copy of the UWP project to someone else to test with (on Windows 10 desktop). This is a new application, not in any stores, so...how to do this? Can it be done without using store distribution, and if so, can someone tell me how to do this, or point me to a link that documents this?
You could create package (like for publishing to store) and then with PowerShell install it on another PC. Packaging UWP apps
You can limit the distribution of an app to only a certain group of testers, without first publishing a submission that's broadly available, you can use the same app submission process as any app you submit. To allow only certain people to get the app free of charge, and prevent other customers from seeing its listing or downloading it - read more about Beta testing and targeted distribution
I followed the documentation(https://parse.com/docs/dotnet/guide#push-notifications-setting-up-push) by Parse for sending Push to Windows 8.1 device. But, I am not able to get through the first step ie. "Installation". As per the documentation I followed , the channel should get registered instantly. I have enabled "Toast capable" within the Package.appxmanifest file in my Windows 8.1 Universal App(C#).
I have also authenticated the App by adding the Package Security Identifier and the Client Secret to the Parse.com Windows Push Credentials settings. But still no success. Can anyone tell me if I am missing anything or if Parse SDK is supported for Universal Windows 8.1 C# App.
I previously had Parse working for WP8 as per instructions here. So this is to say it is definitely doable, follow those steps there to see if you missed any steps.
Caveat
We are using Cordova, but I had to end up doing this part natively. It was working in December 2015 but mysteriously this year we had issues with Parse on all 3 device platforms (iOS, Android, WP8). I'm still spending time trying to figure out why WP8 just doesn't work now, can't even get the device to register to a channel anymore...
I've configured an email ID (obviously gmail id) to 20 android devices all are situated at different place now if i want to install an application. to all device like Avast antivirus
if any device have already installed then how could i be able to do this.
Goal :
1: Install an application to all devices if not intalled.
2: devices may have already intstalled application then it will show install say if one have intall and other don't then how to install in all devices.
I am not too versed in telephony. I know for blackberries you have to have a blackberry [enterprise] server to manage devices in this fashion. I think one client for android is called Good, but if you do a search for android enterprise management, you probably could find others.
How can I run my XCode SDK application on my iPad without key and without jailbreak?
(I found a description yesterday, but cant find it back).
This can be with the device connected to my development machine.
(I can afford the $99, but I cant wait for it to arrive)
Without program membership and without jailbreak? You can't.
