QUESTION
I want to download the file in my app and I used Dio, path_provider, permission_handler
so I should write something in the android manifest for android and info for ios.
and I did it. but it did not work and I've get this error when I clicked on the download button:
...ANSWER
Answered 2022-Jan-05 at 22:03I solved this problem with the following solution:
instead of just asking for Permission.storage i added two more permission requests Permission.accessMediaLocation , Permission.manageExternalStorage in order to support all versions of Android.
QUESTION
edit: Turns out the solution is in the docs. I had bog standard normal 'sam' installed but I needed what they call the 'public preview version' AKA 'sam-beta-cdk'. With this installed the API can be started locally with sam-betacdk start-api and works well. While I appreciate the answers which suggest that development should be done using purely TDD I feel there is also value in this more interactive, manual mode as it permits quicker exploration of the problem space.
I'm trying to build my first app with CDK + Typescript using API Gateway, Lambdas and DynamoDB. I have built a couple of Lambdas and deployed them and they work fine live on the web. However I don't want a minute long deploy cycle and various associated AWS costs as part of my workflow. What I want is to be able to test my API locally.
I have struggled to find docs on how to do this. Amazon seem to recommend using the SAM CLI here so that is what I've been trying.
The docs claim running sam local xyz runs cdk synth to make a "could assembly" in ./aws-sam/build but I see no evidence of this. Instead what I get is a complaint that sam could not find a 'template.yml'. So I manually run cdk synth > template.yml which creates one in the root folder. Then I run sam local start-api and it seems happy to start up.
Then I try and hit my test lambda using CURL: curl 'http://127.0.0.1:3000/test' I get {"message":"Internal server error"} and a huge ugly stack trace in the console that is running sam local start-api
The lambda is this...
...ANSWER
Answered 2021-Sep-15 at 15:15You must be doing something wrong with your file directory. Where is your index.js located? If you generate the template.json, is the directory correct? Also in what directory do you execute the Sam local command?
The thing with testing your serverless application is you don't have to test your full application. You need to count on AWS that API gateway, dynamodb and lambda is perfectly working. The only thing you need to test is the logic you implemented.
In here you make sure your function prints out something and returns a 200. That's all you have to do. Look into 'jest' for testing js.
If you want to test cdk you should into https://docs.aws.amazon.com/cdk/latest/guide/testing.html
Also "running Aws locally" is not good practice. it's never the same as how it's running in real life aka the cloud. You use plugins for this, tools for that... Local is not the same as in the cloud.
If you have any more questions, feel free to ask.

QUESTION
We developed with expo and needed an eject so We ejected from expo with the option to use expoKit. We heard there are two ways to run the server in this state.
- to build in xcode after
expo start - to
react-native run-iosorreact-native run-androidin another tab afterreact-native start
If We run it the first time, it will work as before, but it doesn't load the native library properly. So We ran it the second way, and We get the following error. We think Bundler doesn't map it properly.
Here is a log of react-native start orreact-native start —reset-cache:
ANSWER
Answered 2020-Mar-14 at 03:09The problem was not with Podfile,info.plist or a some command. When using expo eject, I chose the option to useexpoKit. The main reason was that there was no expoKit in the project module.
First, install the library as shown below:
QUESTION
I have a problem with a deallocation of a variable: cache
This is from the tutorial Reusable Image Cache in Swift
Error:
Fatal error: Attempted to read an unowned reference but object 0x280208080 was already deallocated Fatal error: Attempted to read an unowned reference but object 0x280208080 was already deallocated
Code:
...ANSWER
Answered 2020-Mar-11 at 16:04This error has a pretty simple explanation:
by the time URLSession is finishing its work, the instance of ImageLoader does not exist, because nobody keeps a reference to it. It may happen when you just create that instance in function scope variable. (Maybe in some function like viewDidLoad). This crash is useful, as it says that loader is using in the wrong way. In case of usage of weak self or capturing the whole instance, the crash will not happen, but you will have a lot of ImageLoaders with its own caches with one image there. Thus there would be no caching in its meaning.
To solve that, after the creation of ImageLoader instance, you should keep the reference to it in a class/struct variable which is consuming it and pass it to another consumer, who needs the same cache. (a dependency injection technic is a good approach for that). Thus one cache with some amount of items will exist and works.
Or the simplest way is to make a shared instance of ImageLoader and use it only, thus it also guaranties one instance of it with one filled cache.
