Android不能捕获双卡手机从卡的CellId和LocationId

Question

我需要从sim的cell id和location id；但它总是为这两个返回0，并且我的主槽sim不存在。我怎样才能正确地得到它？顺便说一句，我已经做了适当的检查SIM是否存在。

我的代码是：

final GsmCellLocation locationG = (GsmCellLocation) tel.getCellLocation();

    if (locationG != null)
    {
        cellId = locationG.getCid();
        lac = locationG.getLac();
        cellId = cellId & 0xffff;
    }

Answer 1

//you need to check if 2G or 3G

lac = String.valueOf(finalLocation.getLac()); 
cellId = String.valueOf(finalLocation.getCid());

if(3G) { 
   cellId= String.valueOf( Integer.valueOf( cellId)& 0xffff); 
   lac= String.valueOf( Integer.valueOf( lac)& 0xffff);
}
