I have the following code (adapted from this tutorial) that I use for saving files from backend:

import { FilesystemDirectory, Plugins } from '@capacitor/core';
const { Filesystem } = Plugins;

await Filesystem.writeFile({
    path: "filename.txt",
    data: "base64 data",
    directory: FilesystemDirectory.Documents,
  });

This codes works fine on Android, even creates the Documents directory in the root of internal storage. Unfortunately, on iOS no file is created, no mater what directory I use (I've tested it with Documents, Data and ExternalStorage). When I put this code block inside try..catch, nothing is thrown, so the operation is supposedly completed successfully, just no file is saved. Tested on one Android device and two iOS.

I am trying to generate an apk for my app built with quasar, but it still runs on localhost when the apk has been installed on a mobile device.

Steps I've tried

• generate Apk from Android Studio as debug
• generate Apk from Android Studio as release
• edited the quasar.conf.js file to change the host and port
• invalidate caches multiple times
• clean project and rebuild none have worked

when i run from the terminal

quasar build -m capacitor -T android

this is the error I get

> Task :app:dexBuilderRelease FAILED

FAILURE: Build failed with an exception.

I just want my apk to run like a mobile application independent of the local dev server.

quasar.conf.js

    build: {
      vueRouterMode: "hash",
    devServer: {
      open: false,
    },

capacitor.conf.js

{
  "appId": "org.capacitor.appname.app",
  "appName": "appname",
  "bundledWebRuntime": false,
  "npmClient": "npm",
  "webDir": "www"
}

I'm trying to write a mobile app via Capacitor that makes use of PouchDB. When I run the app in the emulator via Android Studio the connection to the remote CouchDB instance fails. I've tracked this down to a failure in the fetch API for certain URLs when running on Android.

To debug I made a minimal web application and wrapped it using Capacitor to run on Android. The app includes the following code

const testFetch = (url) => {
    console.log("Testing fetch", url)
    fetch(url)
        .then((response) => response.text())
        .then((t) => {
            console.log("Respose from fetch:", url)
            console.log(t)
            console.log("that was it")
        })
        .catch((reason) => {
            console.log("FETCH FAILED", url, reason)
        })
}

I then have three tests:

  testFetch("https://jsonplaceholder.typicode.com/todos/1");   // just some JSON 
  testFetch("http://10.0.2.2:5984/simple");    // local pouchdb instance 
  testFetch("http://10.0.2.2:8080/sample.json");  // local http server + CORS 

The second two use the IP address that is an alias for the development machine when running in the Android emulator. I confirmed that I can access all of these URLs from the browser on the emulator but the app succeeds on the first and fails on the second two (error: TypeError: Failed to fetch). When running the base web app in the browser, all succeed (with localhost instead of 10.0.2.2).

CORS headers are in place on all URLs. As far as I can see the app doesn't even try to access the two servers that fail - no HEAD requests for example. I've also tried various other URLs and can't see a pattern to the failures -- eg. it's not the port number != 80.

Any clues as to what is going on would be appreciated.

i am maintaining a capacitor ionic project supporting both iOS and android platform. I can build the project locally and run it on a device without any issue. But when archiving the following error pops up:

I am using following pods:

  pod 'Capacitor', :path => '../../node_modules/@capacitor/ios'

  pod 'CapacitorCordova', :path => '../../node_modules/@capacitor/ios'

  pod 'CapacitorApp', :path => '../../node_modules/@capacitor/app'

  pod 'CapacitorBrowser', :path => '../../node_modules/@capacitor/browser'

  pod 'CapacitorHaptics', :path => '../../node_modules/@capacitor/haptics'

  pod 'CordovaPlugins', :path => '../capacitor-cordova-ios-plugins'

  pod 'CordovaPluginsStatic', :path => '../capacitor-cordova-ios-plugins'

I already desintegrated/updated pods in my ios folder. Cleaned the Build folder shift-command-k. Further there's no special chars or whitespaces in my project name and I did renew all my certificates / load them into xcode. Restarting machine does not solve it either.

What I did as well, was checking the option "For install build only" in my Build phases (Targets > App > Build phases) as suggested here

I haven't touched my build files (capacitor.config, package.json, ...) lately

Update:

Executing the command by hand produces following ouput:
