CB-12218: (android) Fix consistency of null result message
> inconsistent null handling between EVAL and ONLINE bridge modes
> ---------------------------------------------------------------
>
> Key: CB-12218
> URL: https://issues.apache.org/jira/browse/CB-12218
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-android
> Affects Versions: 6.0.0
> Environment: Android
> Reporter: Alan Kinzie
> Assignee: Joe Bowser

>
> If the Android native code invokes the success callback like this:
> callbackContext.success(null);
> then the value given to the javascript callback changes depending on the
> bridge type used.
> If the ONLINE_EVENT type is used, then null will be passed to the javascript
> callback.
> ie: if result is the parameter of the javascript success callback then
> result === null // will be true
> result === "" // will be false
> If the EVAL_BRIDGE type is used, then an empty string will be passed to the
> javascript callback.
> ie: if result is the parameter of the javascript success callback then
> result === null // will be false
> result === "" // will be true
> The value of the parameter given to the success callback should not change
> depending on the bridge type. Since ONLINE_EVENT was the default before
> cordova android 6.0.0, I am inclined to think the ONLINE bridge is doing the
> correct behaviour. Also, converting null to an empty string loses
> information. Therefore I think the EVAL mode should to be changed to be
> consistent with the ONLINE mode.
