Store Firebase data locally on phone

Hi, I need to get records from Firebase and store them locally in my Ionic 3 app such that every time I open the app, it checks Firebase for changes and updates the local one if need be. It needs to be listening for changes even when the app is closed. Kinda like an email app (when you open an email app, all the previous messages are already there - no need to redownload from the server - and is updated when new messages arrive).

Right now, every time I load the app, it pulls fresh data from Firebase, and when I navigate to a different page and return, it does a fresh pull of data. I’d rather it get all the data one time and store locally, only updating when there’s a change. It should also be listening to Firebase for changes.

How do I achieve that?

Thanks.

Has this been solved yet, or do I still have to use the workaround described by Uehara?

HTTP: Onesignal does not accept my message

Try inspecting what’s really being sent to the OneSignal API from your app. You can do that by running in a local browser like Chrome with ˋionic serveˋ, open the developer tools (usually with F12) and choose the “Network” tab. There you can see request headers, payload and reply for every request sent from the browser app.

I assume there is some kind of translation happening when Angular serializes your “body” object into raw post data, e.g. escaping the double quotes.

In your project-properties, try changing com.google.android.gms:play-services-analytics from 11.0.1 to 16.0.8.

Good luck.

Did you solve this issue? I have the same problem – it doesn’t seem to matter which version of the googlemaps plugin – it builds and runs fine for me local but not on AppFlow.

Am starting a new project on ionic version 3.20

Every time I update a file, the web page isn’t refreshing/rebuilding, where it suppose to live reload on “localhost:8100”. So am stopping ionic and run “ionic serve” again on every update.

Although when i refresh the web page (localhost:8100) the page is reloading till infinity.

I have uninstall cordova and ionic, and still same issue.

Any solutions please?

theming inside shadow dom - v4

June 7, 2019, 11:09 am

Hi All,

I’m facing some problems with theming ionic components (v4) and shadow DOM. In my ionic-pwa from stencil I even don’t get it to work.

For example:
<ion-button fill="solid" expand="full" color="success">Success</ion-button>

Without shadow DOM enabled this results in a success button as expected.
With shadow DOM enabled, the ion-color-base variable doesn’t seem to point to the success color.

To reproduce it:

  1. Install https://github.com/ionic-team/ionic-pwa-toolkit
  2. Go to this file: https://github.com/ionic-team/ionic-pwa-toolkit/blob/master/src/components/app-home/app-home.tsx
  3. add ‘shadow: true’ after rule 5.
  4. add ‘color=“success”’ to the ion-button

Regards, Peter

Hi,
We generated the bundle with Android Studio.

The steps are:

  1. Launch Android Studio
  2. Go To Import Project (Eclipse ADT, Gradle, etc).
  3. Select Android platform directory in your project (/platforms/android).
  4. Wait to finish the Sync
  5. Go to Build > Generate Sign Bundle
  6. Complete Signing info
  7. Upload de .aab file generated (in path /platforms/android/outputs/

Note: if you have problem related to minSDK version, fix this and make a resync

I am trying to create an interactive graphic on one of my pages that will allow me to click on a body part and it will toggle a value behind the scene and then also toggle a fill effect (filled if selected, not fill if unselected). (See the attached example)

Can anyone point me in the right direction?
