[jira] [Resolved] (CB-13696) the camera fails to open to take a
picture after suing proguard in android environment
[ https://issues.apache.org/jira/browse/CB-13696?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joe Bowser resolved CB-13696.
-----------------------------
Resolution: Won't Fix
It's clear that the FileProvider also has to be added as well for this to work. We recommend not using ProGuard with Cordova because we can't guarantee that your ProGuard approach will work for all plugins, since the WebView is technically able to be swapped out using a plugin and it uses a different interface.
