I’m new to Ionic and I’m up and about playing around with the framework. I wanted to test data persistence over app restarts. I was trying ionic 2’s storage on the ionic 2 docs, which I believe I followed well but can’t get the data to persist (both on browser and Android device at 6.0).
Basically what I did is I have a text input which I will save its content via storage. On app restart, I’ll display a toast of the last saved text in the input, the following way (presentToast is just a function to handle toast and ‘name’ obviously is the key):
this.storage.get('name').then((val) => {
val ? this.presentToast(val) : this.presentToast("nothing saved!");
});
That is done on an ionViewWillEnter() hook so its called every time the page becomes active.
But on app restart (after saving an item to storage), I get the latter toast (i.e. “nothing saved!”). What am I doing wrong?
Another thing to notice is that, on the browser console, it says Ionic Storage driver is asyncStorage. I tried to play around with storage.js such that I changed the driver to LocalStorageWrapper. I believe the docs said it should be able to do things automatically but oh well. After that change, I got the data to persist on the browser (i.e. saved value shows on the toast). However, on my android device, it’s still the same case.
