I have a list which I get from firebase and displaying those values in the UI using SwipeListView.

The list data contains details like: coin price, count of coins purchased, total cost of the coins as price,count and amount. And some other fields.

Now, I want to make aggregate of all the coins and display in the text field. But the aggregation I am not able to set.

I tried creating two variables and setting those using hooks but getting error as

I am VERY VERY new to React Native. i have never posted on a forum, sorry if formatting is incorrect. Please bear with me. When i store a value using Async, i write to the console, so i know it is storing the value, then i read back the value and i know it is there when i read from the console but it wont set my radio button to the value stored using Async. The first line of these 4 does NOT work even though i KNOW the data is set but the 3 commented out lines each work fine if i test them separately but it is the first line i want to work:

I am a bit new in react native and I have got into an interesting situation. I have a Login screen in which there are two fields;

1. Mobile number.
2. password

On Login button press I am executing two functions :

1. handleMobileInput() - which check if the mobile number is valid. 2 handlePasswordInput() - which will check if password is valid.

I also have a global state named 'errors' initially it is empty object({}) and 'setErrors' function to update it. Full code looks like this

I am newbie to react native with expo, I have created a functional component that tries to do things similar to the behavior of the TextInput of react-native-paper, with animations and so on.

The problem is I have several instances of this component on the same screen and when I press on the first one to write to it, the rest of them also get focused. And if I fill any text in the first one, the second one triggers the notifications without having been touched.

I am using formik, Yup and typescript.

I have a react native app which is on play store for some time and recently i received this important notice from play store, stating if i don't fix this my app will be removed from play store.

Can anyone tell me what this is and how to fix it?

Here is the complete message from Play store

We've detected that your app contains the requestLegacyExternalStorage flag in the manifest file of 1 or more of your app bundles or APKs.

Developers with apps on devices running Android 11+ must use Scoped Storage to give users better access control over their device storage. To release your app on Android 11 or newer after May 5th, you must either:

• Update your app to use more privacy friendly best practices, such as the Storage Access Framework or Media Store API
• Update your app to declare the All files access (MANAGE_EXTERNAL_STORAGE) permission in the manifest file, and complete the All files access permission declaration in Play Console from May 5th
• Remove the All files access permission from your app entirely.

For apps targeting Android 11, the requestLegacyExternalStorage flag will be ignored. You must use the All files access permission to retain broad access.

Apps requesting access to the All files access permission without a permitted use will be removed from Google Play, and you won't be able to publish updates.
