Hey all,
I'm using the Arduinodroid Android app to work on my project. To give you some context; my project compiles successfully on the Arduino web editor. But when I try to compile my project on Arduinodroid I get the following error:
ITEADLIB_Arduino_Nextion/NexUpload.h:20:16: fatal error: SD.h: No such file or directory
#include <SD.h>
^
is that file available in your "Arduidroid" environment? is the SD library installed in that environment?

Yeah the SD library is installed. I even deleted it and re added it to make sure.
I'm sorry, do you mean the NexUpload.h file?
That file is this:

I mean SD.h. Are you sure the library is properly installed and that file exists?

It shows up in the library manager under installed libraries. There is a file called SD.h in the library.
Try adding this line to the top of your sketch:
#include <SD.h>
Years ago, the Arduino IDE required you to add #include directives for all library dependencies to the sketch. Since that time, the Arduino IDE's dependency resolution system has been improved so that is no longer required, so you will find newer sketches often don't bother to clutter the sketch up with #include directives that are no longer necessary. It's possible that the Arduinodroid app has not been updated to match the modern capabilities of the Arduino IDE and the Arduino Web Editor.

Thanks that solved that error. However I am getting a new errors, and since the app won't let me copy the error text I can't share what the error says (I manually copied the text for the previous error).
