Mostrar datos de una Tabla en Android Studio con SQLit

tengo esta tabla Producto con estos atributos, pero el atributo Categoria está relacionado a otra tabla(para registrar un producto se debe registrar el id de la categoría al que pertenece)

    private int idproducto;     private String desproducto;     private double preproducto;     private int canproducto;     private Categorias categorias; 

El problema es que para listar no se como hacerlo para mostrar el id de la categoría o el nombre… El cursor solo me acepta getInt, getString mas no para obtener el dato de otra tabla relacionada, ayuden; mi método para listar es el siguiente:

public static ArrayList<String> listarP (ConexionSQLiteHelper cnn) throws Exception     {         ArrayList<Productos> lst=new ArrayList<Productos>();         ArrayList<String> listaInformacion=new ArrayList<String>();         Categorias categorias = new Categorias();         Productos opr = new Productos();         String sql="select * from productos";         Cursor cursor=cnn.ejecutarQuery(sql);         try{             if (cursor.moveToFirst())             {                 do {                     lst.add(new Productos(cursor.getInt(0), cursor.getString(1), cursor.getDouble(2),cursor.getInt(3),cursor.get(??)));                 }while (cursor.moveToNext());             }              for(int i=0;i<lst.size();i++)             {                 //listaInformacion.add(lst.get(i).getIdcategoria() + " - " + lst.get(i).getDescategoria() );              }         }catch(Exception ex){             throw ex;         }         return listaInformacion;     } 

En la parte que dice: cursor.get(??) no se que poner para obtener el id o el nombre de la categoría.

¿Cómo cambiar la intensidad de vibración en Android Studio?

Estoy realizando un proyecto en Android Studio. Ya sé como hacer que un botón libere una vibración$ .

Mi duda es si existe o hay una manera de poder cambiar la intensidad de la vibració$ n. Es decir, en el código anterior se le aplica la duración de la vibración$ , ahora lo que necesito es manipular la intensidad de la vibración$ . Por así decirlo disminuir la intensidad de la vibración$ .

boton.setOnClickListener(new View.OnClickListener() {         @Override         public void onClick(View v) {             //Vibrate in milliseconds             //For example 2000 milliseconds is 2 seconds             vibrator.vibrate(1000);          }     }); 

Android exploited – elevated privileges – SE Policy exploit – system as root – dual boot – living in my ramdisk. What now? [on hold]

Ive been chipping away at this for days and going in circles so I need to put this out there – somewhere.

My Samsung s9+ hasnt been acting properly for a long time – but in the past few weeks this thing has become a nightmare. Calls and messages come through sometimes days late or apparently days early as the time is changed routinely. The OS is constantly reverting back to some kind of stock image (android pie it is not) with settings completely reset. Weird errors have forced resetting several times and my photos have all been destroyed in random ways (faces altered, photos smudged, scratched out etc). Daily backups have been ignored.

I will attach some of the snide logs this thing generates as well as the init.rc and build.props (fstab goldfish files etc) – im not sure what is handy so i will wait for a response as i have most system documents. These system files and logs that show that adbd is placed in the privileged position pre init – it then discards any update or change installing instead from a hidden partition (or network – the thing is never offline or properly shut down). There it remaps me to a virtual disk and assumes root control of my operating system. I am not sure if it is timed or if there is someone behind it – but as i get close to removing the files (or think i do) it will pretend to brick for an hour or two and then suddenly leap into recovery mode.

Now im not concerned with the causes or what its doing. In its current condition i cant factory reset or erase with odin as it has positioned itself to respond to exactly this threat. Before the setup screen presents this thing has root access and is busy setting tasks and countdowns – similar behaviour is manifesting itself in my PC but i think this exploit has had longer to stretch out on the phone. Can anyone offer any assistance. Its sending me nuts being trapped fixing the damn thing.

Como lograr que un webservice informe a un determinado cliente (Android) que sus datos fueron actualizados?

Estoy en desarrollo de una aplicacion en donde una vez que el cliente inicia sesion o se registra, el servidor busca en toda la base de datos que roles (encargado de limpieza, seguridad, etc) tiene el cliente, para asi poder armar un menu (Navigation Drawer) dinamicamente dandole opciones para acceder solamente a sus respectivos roles de trabajo. En caso que un determinado cliente haya sido ascendido, promovido o asignado un nuevo rol de trabajo, el servidor debe notificar al cliente (que es un dispositivo android) que sus datos fueron actualizados y automaticamente(en segundo plano) actualizar el menu(navigation drawer) agregando una nueva opcion para acceder a su nuevo rol de trabajo.

Como puedo lograr esto? cualquier sugerencia o recomendaciones son bienvenidos. Gracias.

Nota: Mi webservice esta hecho en php.
