            Firebase crashlytics not able to read crash reports
            Asked 2022-Apr-11 at 14:08

            I have configured crashlytics as per Firebase Documentation But crash reports not generated and uploaded to server.

            Kindly refer my build details.

            Here is our project-level build.gradle



            Answered 2022-Apr-11 at 14:08

            There was another utility logger library initialized in the application class that prevented crashlytics from collecting log.

            Also the initialization & manifest part is not necessary unless you want to explicitly enable/disable crashlytics working.



            Modify For loop to go from certain string forward and delete a selection of lines using batch
            Asked 2022-Mar-28 at 12:50

            Ok so i am writing a batch file in which i delete every line containing "," after finding string: "plugins": { Is it possible to make this condition in for loop ?

            now i know you can avoid quotes using ^ but i just cant make it work.

            what i do right now is the following:



            Answered 2022-Mar-28 at 12:50

            Keep in mind, batch can't interpret .json files and handles them as pure text. So any batch solution will highly depend on the exact format of the file. Any change in the format (a stray space might be enough) may cause trash.

            That said: use a flag that changes at (each) line that starts with "plugins": and changes back when hitting the line starting with } (end of the block) and write the line dependent on the flag:



            Angular is not recognizing ion tags
            Asked 2022-Mar-23 at 17:38

            I upgraded angular to angular 13 and cannot get my project to build or serve. It appears that Angular isn't recognizing any of my ionic tags in the .html files. What am I missing?

            I am able to run npm install without issues. I have deleted the node_modules and package-lock.json files, removed the platform and then run npm install and added the platform back. That is successful, but running ionic serve or ionic cordova build android results in a whole stream of errors that looks like angular isn't seeing the ionic html tags and there are new errors with Promises and more.

            I get a ton of these errors:

            This is what I get when I run Ionic info:

            my package.json....



            Answered 2022-Mar-23 at 17:38

            Figured out what the issue was. MicrosoftSDK had TypeScript 3.1 and first when running "where tsc". I moved the npm directory up in the Environmental Variables. Then I removed Angular and reinstalled it.



            Grey Screen when release to store without error
            Asked 2022-Mar-17 at 13:10

            There is a float action button and it opens a dialog. It works fine in debug mode without red error. However I uploaded the google and app store, it shows grey screen. Then I tried to run in release mode with Flutter run --release. It works fine with that. I could not find any error or any reason why it shows grey screen.



            Answered 2022-Mar-17 at 13:10

            mark these two options in debug menu, you'll see a red screen on your device/emulator, that's what the problem is. Try to solve the issue.

            if that's not working try to run app in release mode by running the following command:

            flutter run --release -v and see the result in terminal in VS code



            How to get the updated value and apply it to another function in React Native?
            Asked 2022-Mar-14 at 06:59

            as for someone new to react native, how can I get the updated value from usestate and apply it to another function? for example here is my code:



            Answered 2022-Mar-13 at 19:10

            We could pass the barcodeData back to the HomeScreen using route params. Actually, from the code that you have provided, we could remove the state in BarcodeScanner and pass data in the handleBarCodeScanned function directly.

            This could be implemented as follows. I assume that HomeScreen is a Screen defined in a navigator.



            React Test prop component is not called with async
            Asked 2022-Feb-24 at 23:10

            I have a problem with a test in React.JS. My component scans a QR Code Image, I use this dependency: with version 1.4.1

            This is my test



            Answered 2022-Feb-24 at 20:24

            You have an incorrect mock for onScan and you are not waiting for results. The action is resolved in the next "tick" not instantly. I think this should work (not tested)



            Should every view have a ViewModel?
            Asked 2022-Feb-01 at 04:13

            I've been developing in Android for a few months back and I am currently learning and implementing MVVM arquitecture, but the info related in Internet confuses me a little bit.

            Google recommend to have only one viewModel per view, other resources says that is not necessarily for all views....

            In my current project I have a view where i don't know if is needed or not, main activity has a RecyclerView with clickable items (this activity has his viewModel) and when user clicks on one item it takes him to a details page populated using Bundle (I think until this point a viewmodel is not needed, or it is?), but as an update I want to implement a BarcodeScanner button in main activity and as result it will make a GET to an API and populate the same view (details with de result of the call).

            I this case, does my details view needs a viewModel?

            Any info is appreciated.



            Answered 2022-Feb-01 at 04:13

            It is a design choice. It is not necessary for any view to have a view model to function. However, Google recommends the pattern because it leads to good design.

            If you want to say that your app is MVVM, then you need to keep the view separated from the data that drives it. This typically requires a translation layer to query and transform the model data in to data that can be consumed by the view.

            I didn't read this article thoroughly, but it has a diagram that illustrates the relationship between the model, view model, and view:


            In your barcode scanner button example, the API server can be thought of as the model. Your view model should interface with the API (make the GET calls) in such a way that it can post updates to the view (typically using LiveData). The view stays up to date by observing the API results.

            I would recommend isolating the interface to the API in it's own class or service. Then the view calls the view model when the barcode scanner button is clicked and the view model call the API class.

            Regarding your bundle populated details page question: It's hard to know without looking at your code, but presumably your main activity is populated from data in a database (whether local, or through an API). You recycler view contains a list of items, and upon selecting an item, it's details are displayed in a new view. If I were implementing that, I would pass only the ID of the item to the detail view and initialize the view model with that same ID. Then the view model would lookup all data associated with the item and display it.

            Presumably more data is displayed in the detail view than in the RecyclerView. The main activity does not need to access the item details or hold them in a ViewAdapter (and should not).

            However, these are all design choices. There is nothing that says your app has to be written a certain way or follow a certain pattern. It can function regardless. My advice is to follow the pattern even when you think you don't need to until you learn why you need to!



            react-native webview in Expo App shows 'about:blank' on Android before exiting the APP with BackHandler
            Asked 2022-Jan-24 at 14:53

            Good day everyone,

            I have a problem with an App that gives me some headaches for couple days. The App consists of a WebView containing a PHP WebShop and a bar-code scanner. So far everything was working as expected.

            For better Navigation on Android I wanted to use the HardwareBackButton to go back in the WebView History. This also works well but has a major flaw. I want the back button to go back until it cant go back anymore and instead it should exit the App. Now to the actual problem: the last Page url is 'about:blank' and results in a blank screen. From here the canGoBack state is false and the App exits as expected but if you open the App again its still in the 'about:blank' state. My first workaround was to add this.WEBVIEW_REF.current.goForward(); before BackHandler.exitApp;. This helps to get the App back in a navigateable state after exiting but i would like to completely get rid of the blank screen.

            I Hope the code below is enough to understand what i wanted to achive:



            Answered 2022-Jan-24 at 14:53

            I found a workaround for the Problem. The App has a SplashScreen on start and I simply set the state of canGoBack to false and am clearing the WebViews history when the SplashScreen closes.



            Expo BarcodeScanner works only the first time when I post data to my server on barcode scanned
            Asked 2022-Jan-22 at 13:33

            Expo BarcodeScanner works only the first time when I post data to my server on barcode scanned



            Answered 2022-Jan-22 at 13:33

            How about toggling some kind of waiting period while the data is actually getting sent to your server via the POST in a synchronous matter to stop the scan and then reactivate it right after?

            I don't have the chance to test it on an actual device and replicate it to the precise bit but I hope you'll get the gist of it:



            expo-barcode-scanner only works once with react-native version 0.64.2 and expo 43.0.0
            Asked 2022-Jan-12 at 17:35

            Because of Google Play, I had to update an old project of mine to the latest expo versions (version 43.0.0 to be exact). The idea is for the app to scan a QRCode and process the data, simply. However, expo-barcode-scanner only works once and after that I need to close and open the app again to work. Has anyone encountered this problem and (or) knows how to solve it? Below is my code:



            Answered 2021-Nov-12 at 21:14

            Welcome @Backup Gov18,

            This is a documented issue.

            Note: Only one active BarCodeScanner preview is supported currently. When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use without issues.

            There is a workaround.

            Instead of conditionally rendering the component, you could render it inside another dedicated screen component.

            This way, after this new screen reads the barcode, you could navigate back to your first screen. Navigating back may unmount this new screen. You can force unmount if you need to.

            As you are using react-navigation, you had better use .pop() instead of goBack().


            You can also use expo-camera instead of expo-barcode-scanner. expo-camera does not have this issue. It also offers more options like flashlight/torch and switching cameras.
