I have one old Azure Functions project (v3). It contains several timer triggered functions. They stopped working on VS2022. You can see the logs below. If I create a new Functions project via VS2022, it will work fine. Looks like Azurite also starts up fine. Setting "AzureWebJobsStorage" equals "UseDevelopmentStorage=true". What can I do?
...ANSWER
Answered 2022-Jan-06 at 12:33Created the Azure Functions v3 Project in Visual Studio 2019 along with the azurite extension to the project and running locally:
Same Code opened in VS 2022 and run the function locally:
As given in the Microsoft Documentation, Azurite is automatically available with the VS 2022.
When you open the Azure Functions v3 project (earlier created in VS 2019) in VS 2022 now, it might show this messages in the output dialog box after loading the dependencies:
Still, the Azure Storage Emulator is required to run any azure functions project in the Windows, it needs to be installed in the system.
Make sure the Azure Storage Emulator is installed and the azurite is a future storage emulator platform included with VS 2022. If you're using earlier Visual Studio, you'll need to install Azurite by using either Node Package Manager, DockerHub, or by cloning the Azurite github repository given in the following documentation.
QUESTION
The following macro is from an MCAL source of a microcontroller and it converts timer ticks to milliseconds.
...ANSWER
Answered 2022-Jan-20 at 13:16The multiplication and addition are in fact pointless, as is the outer cast.
Both operators perform the usual arithmetic conversions on both operands.
For the multiplication, the left operand has type uint64
(as a result of the cast) and the right operand has type int
. Since uint64
is the larger type it will be the type of the result. The operand 1
does not change value as a result of the conversion, so in multiplying by 1
the result has the same type and value as (uint64)(x)
.
Similarly for the addition, the operands are of type uint64
and int
respectively, meaning the resulting type is uint64
, and 0
does not change value after the conversion. So by adding 0 the result has the same type and value as (uint64)(x) * 1
which has the same type and value as (uint64)(x)
.
The cast at the end is also superfluous, as the casted expression already has type uint64
. As above, the division operator performs the usual arithmetic conversions on its operands so dividing a uint64
by an int
results in a uint64
.
So the above macro is equivalent to:
QUESTION
Is there a way to detect when the app has been minimized? Simply using WidgetsBindingObserver
with the paused
event doesn't work as it's indistinguishable from when the user turns off the screen / phone locks. Note, I need this to work for both android and ios.
A bit of context of what I'm doing. In the application, I'm running a timer. I want to stop this timer if the user minimizes the app (e.g. uses its phone for something else). If the user, however, turns off the screen/locks it, I want the timer to continue.
...ANSWER
Answered 2022-Jan-13 at 20:48I suggest to take a look at this package: is_lock_screen
As the description suggest
Useful for determining whether app entered background due to locking screen or leaving app.

QUESTION
I am developing an app where the app will detect Bluetooth signals (Sensoro Smart Beacon device) and open the activity. But I want the app to still be able to detect the signal even when the application on the background or even when killed. I used a foreground service, it detects the signal when I open the application and move between activities but when sending the app to the background and opening other applications, the listener stops although the service still working. I am printing the logs. System.out.println("Sensoro 2" );
keeps printing even when I kill the application or open another application. But the printing logs in BeaconManagerListener are not working. I tried to use background service but it didn't work also.
Can you please advise if there is a way to make the listener works in a service when the app in background or killed?
Here is the service code:

According to Google documents, from Android 8 onwards, all applications that do not have a Google-approved signature will be removed from the background after a few minutes.
But the solutions:
- The first solution is to run the application in debug mode
- The second solution is to assign a signature to the application and send it to Google for approval
recommend:
- The third solution is to remove the google play service application from the emulator or android phone
