Ola Pessoal,
como extrair do celular o sinal da antena (fraco/forte/sem sinal), o nivel da bateria (voltagem ?) e um identificador unico do aparelho (numero , emi)
obrigado.
Depende do fabricante, se ele libera para que vc implemente essas funcionalidades.

Fala malves_info,
é um i876 motorola, mas c tiver metodo generico melhor ainda pois posso aplicar a outros devices.
penso em algo simples como double latitude = c.getLatitude();
ouble longitude = c.getLongitude(); mas sem ter que usar uma location api pra obter os dados que falei 
obrigado!
nos motorolas tem como pegar a bateria System.getProperty("batterylevel"); esse metodo retorna valores inteiros aí tem q ver na APi como está implementado no seu aparelho, pois no meu um V3 ele retorna 0,1,2e 3 3 = cheia, 2=media 1=fraca, zero=vermelha de um olhada abaixo
Java.lang Implementation
Motorola?s implementation for the java.lang.System.getProperty method supports additional system
properties to those specified in JSR 118.
The additional system properties are:
The IMEI and MSISDN properties are not available for unsigned MIDlets. For more information on this
class, go to http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html. The following code sample
shows the java.lang implementation.
System.getProperty(?batterylevel?)
System.getProperty(?MSISDN?)
System.getProperty(?CellID?)
System.getProperty(?IMEI?)
The following information is provided from the java-tips.org web site and can be seen in its entirety at
http://www.java-tips.org/java-me-tips/midp/how-to-retrieve-system-properties-in-a-midlet.html.
This Java ME tip illustrates the retrieval of system properties in a MIDlet. MIDlets have direct access to all
four of the standard system properties defined by the CLDC specification.
CellID The device?s current Cell ID is returned during implementation.
batterylevel The application?s current battery level is returned during implementation.
Battery values are: low battery, 1,2, and 3, based on the battery level.
IMEI International Mobile Equipment Identity. The device?s IMEI number is returned during implementation.
MSISDN Mobile Station Integrated Services Digital Network. The device?s MSISDN of the device is returned
during implementation.

The following table is from the Sun Developer Network (SDN) web page,
http://developers.sun.com/mobility/midp/questions/properties/index.html.
This table lists the defined system properties, drawing them from JSRs that are in the public review, final
ballot, or final state, as defined in the Java Community Process (JCP):

Fmz JJjava,
vou testar agora!!
[]s
testei no i876 e nada.
dei uma olhada na api do p/ oi876 e tb nao consegui.
a Status Manager API é quem instancia objetos para recuperar nivel de sinal e bateria.
criei uma instancia desta classe e fiz uma chamada aos metodos e nada. acho que fiz alguma besteira pois nao conseguir com a api na mao…
onde tem um tutorial em portugues sobre uso de api padrao java ou msmo de terceiros, pois e´a segunda vez na vida que uso api não padrao
obrigado e bfds a todos
