Example 6 with PluginManager

use of org.apache.cordova.PluginManager in project cordova-android by apache.

the class MessageChannelMultipageTest method testThatCachedCallbackIdIsValid.

//test that after a page load the cached callback id and the live callback id match
//this is to prevent a regression
//the issue was that CordovaWebViewImpl's cached instance of CoreAndroid would become stale on page load
//this is because the cached instance was not being cleared when the pluginManager was reset on page load
//the plugin manager would get a new instance which would be updated with a new callback id
//the cached instance's message channel callback id would become stale
//effectively this caused message channel events to not be delivered
