) access_coarse_location or access_fine_location. public int getdataactivity () returns the status of the current data connection activity. public int getdatastate () returns the condition of the current data connection state. Public String Getdeviceid () Returns the device ID of the cell phone. For example, for GSM mobile phone is IMEI code, for CDMA mobile phone Meid code or ESN code. If the read fails, NULL is returned.
