Summary:
Implement a handler to allow intercepting all RN redboxes in Android, including exceptions in both JS and Java.
The handler is not open sourced, so there is only an open-source interface called **RedBoxHandler** in //fbandroid/java/com/facebook/catalyst/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/devsupport//, meantime there is an internal class called **FBRedBoxHandler**, which implements **RedBoxHandler** and is located in //fbandroid/java/com/facebook/fbreact/redboxhandler//, actually handles the exception information.
The code structure is as follows:
- **AdsManagerActivity** has a member variable of **FBRedBoxHandler**.
- **AdsManagerActivity** passes this handler all the way down to the **DevSupportManagerImpl**, through** ReactInstanceManager**, **ReactInstanceManagerImpl**, **DevSupportManagerFactory**.
- **DevSupportManagerImpl** intercepts the exceptions just before showing the redboxes, like this:
mRedBoxDialog.setExceptionDetails(message, stack);
mRedBoxDialog.setErrorCookie(errorCookie);
if (mRedBoxHandler != null) {
mRedBoxHandler.handleRedbox(message, stack);
}
mRedBoxDialog.show();
By now, the internal class just prints information for each redbox to logcat, including exception message and stack trace.
