JarCastingokhttputils
Contains various different utilities for the OkHttp library usable across multiple projects.

Remove the excludes if the libraries are not already present in your app (they most likely are :D)

HttpErrorManager
This is a global error handler for http requests performed by the OkHttp library. The idea is that instead of having to handle common error codes like 442 (invalid token) each place you make the request, you implement a handler for the error code once and for all.
There is no initialisation since the library use the firebase content provider trick to obtain a Context.
Usage
To show a message in a dialog when a certain error code is returned:
HttpErrorManager.setHandler(500, new HttpErrorHandler("Ach nein! eine internal server fehler has passiert!!!", true);
To show a message in a dialog and run some code after the user dismiss it:
HttpErrorHandler invalidAuthHandler = new HttpErrorHandler("Ach nein! deine Token sind KAPUT!!") {
@Override
public boolean onError(int code, String url) {
// Only show dialog if the endpoint url does not contain the word login
if(url.contains("login")) {
return false;
}
return true;
}
@Override
public void onDialogClosed() {
// This code gets run after the user dismissed the dialog
Intent intent = new Intent(App.this, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
};
// register the handler above for error code 442 and 443
HttpErrorManager.setHandler(442, invalidAuthHandler);
HttpErrorManager.setHandler(443, invalidAuthHandler);
If the user returns true from the onError method the dialog is shown. If no dialog is shown the onDialogClosed function will not get called.
