Ionic无法在Android 4.4.2上加载

Question

I am using:

Your system information:

Cordova CLI: 6.4.0 
Ionic Framework Version: 3.0.1
Ionic CLI Version: 2.1.18
Ionic App Lib Version: 2.1.9
Ionic App Scripts Version: 1.3.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: macOS Sierra
Node Version: v6.9.4
Xcode version: Xcode 8.3.2 Build version 8E2002

I have built an app with:

ionic build android

This builds the relevant apk file, that I can install to an Android devise.

I have tried a number of devises successfully:

Samsung Galaxy S7 with Android 6.0.1
Samsung Galaxy S5 with Android 5

However, when I try install it on the following, it seems to just hang when I launch the app:

Samsung Galaxy Tab with Android 4.4.2

I have added an alert to the top of the constructor in app.components.ts , but this does not get fired on the Android 4.4.2 devise.

If anyone can offer any ideas I would appreciate it.

Answer 1

Ionic doesnt provide support for 4.4.2 See github issue

Key points :

1. you can use crosswalk

Key Commands

ionic browser add crosswalk

2. when u will use this however angular date pipe will break. As per comment

"Hello @windwp! Ionic 2 does not currently support the Android browser, although we do support chrome for Android. The date pipe uses the internationalization API which is not supported in older browsers such as the Android browser. Sorry for any hassle that causes you, and thanks for using Ionic!"

So possible solution is

a. use moment [angular2-moment]

{{myDate | amDateFormat:'LL'}}

This will work everywhere.

b. use intl js polyfill .
