Era sencillo de solucionar estaba duplicado el código.

Pero salimos de un error, y entramos en otro...

5 errors

No sé si falta algo por declarar... el commit sigue siendo este: https://github.com/NPCod/frameworks_...11732493ff6b11 estoy comparando con mis archivos originales y lo veo bien.. voy a seguir mirando.

En tu archivo "services/java/com/android/server/pm/PackageManagerService.java" debes añadir los siguientes imports:

import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileDescriptor;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.FilenameFilter;
import java.io.IOException;
import java.io.PrintWriter;

Con esto creo que solucionarás los tres primeros errores. Si no, revisa los imports y esas cosas. Los otros dos errores son porque has añadido esta línea de más en "services/java/com/android/server/SystemServer.java":

final RotationSwitchObserver switchObserverF = switchObserver;

Que por cierto no se de donde la has sacado, porque en el commit original no está... jaja!!!

Suerte!!
