which I need to save to shared preferences and get back later.
Code to save json works fine
public static void addSelectedYoutubeAccounts(Context context, ChannelListResponse response) {
Gson gson = new Gson();
SharedPreferences sp = context.getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
String data = response.toString();
// data = gson.toJson(response); // didn't work either
editor.putString(PREF_SELECTED_YOUTBE_ACCOUNTS, data);
editor.commit();
}
But when getting it back to the ChannelListResponse object of google api client library with below code
public static ChannelListResponse getSelectedYoutubeAccounts(Context context) {
Gson gson = new Gson();
SharedPreferences sp = context.getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
String data = sp.getString(PREF_SELECTED_YOUTBE_ACCOUNTS, "");
ChannelListResponse response = gson.fromJson(data, ChannelListResponse.class);
return response;
}
I get the following exception
