The PermissionHelper class is not actually obsolete and should not be deleted. This helper class is used by plugins.

Here are some examples:

• https://github.com/apache/cordova-plugin-file/blob/master/src/android/FileUtils.java#L42
• https://github.com/apache/cordova-plugin-geolocation/blob/master/src/android/Geolocation.java#L27
• https://github.com/apache/cordova-plugin-camera/blob/master/src/android/CameraLauncher.java#L52

Above points to the imports but if you scan the file you will see it being used.

While the above are Cordova core plugins, I believe many third-party plugins also use it.

But the PermissionHelper is deprecated and obsolete anyway, or? Because you must not use it can directly call everything on the CordovaInterface of the CordovaPlugin. I would mark everything in the PermissionHelper as deprecated, what do you think?

I deprecated the PermissionHelper in this PR: #1857
