Is there anyway to get current signal strength on Android device. I know there is a way where you can listen for signal strength change, but i cannot wait and need to know the current signal strength.
Any help would be appreciated.

You can register the PhoneStateListener and save the last updated value into a variable and access it whenever you need it. It is the closest approximation of signal strenght you can get in real time.
you can download https://play.google.com/store/apps/details?id=com.nolanlawson.logcat&hl=en
from the app store on your device and while you move in and out of an ssid it will show you the signal strength pretty accurately. Hope this helps. Cheers.

I would like to get the overall signal strenght received with the mobile antenna. Ideally, I would love to get the electric field measured with my phone antenna.
I did found a lot of methods to get the signal strength but they all give a specific signal strenth (either GSM, Wifi, GPRS ...) but not the overall signal. Moreover, if there are no SIM card in the phone, the GSMsignalStrength will return 0 or null and even if there is a SIM card, I will only get the strength of the signal of that operator only.
Could you please help me?
I am trying to create an app which gives signal strength of various mobile networks ,
here is a few things I need to know
1 : I am getting phone signal strength like 13,14,17 using TelePhonyManager ,
what it actually means
2 : So if this declares the mobile signal strength , can the same strength be assumed for data being using using edge , 3G or any other way
i dont need full source codes ,
a little guidance should be sufficient.
I was wondering if you can set signal strength parameters. In andriod.telephony class I only see methods which get you the values, however, is it possible to set values too ?
No. Signal strength is a measurement of a physical thing- the ratio of signal to noise of the cellular signal. You can't set that- it is whatever it is. You can set its variable to 1 billion, it won't effect the physical reality. The only use of it would be to lie to other apps about what the real signal strength is. And no, there is no way to do that.
Hi, is there a way i can check if my android phone has lost its GPS signal. I can find out if the GPS signal is retrieved back but is there a way i can check when the signal is initially lost?
I have tried checking if the longitude or latitude is 0, but i have not observed either of them becoming 0 when i lose the signal.
Thank You!!

Question is as simple as the title: How to measure GPS signal strength?
Are you sure you mean signal strength vs. accuracy? What good is the signal strength? Since the GPS position is determined via many satellites, you don't have "one" signal strength.
So assuming that you really mean signal strength, you can get the GpsStatus via LocationManager.getGpsStatus(), and that gives you a list of satellites via getSatellites()', and each one of those has a signal-to-noise ratio (getSnr()).
Assuming you mean accuracy, try Location.getAccuracy().
You can read signal strength in MNEA message GSV in SNR-Signal to Noise Ratio.
Signal strength is VERY important. Too weak of a signal and the receiver can't track them. You need several 'strong' satellites to get position, not just one.
Older receivers couldn't track in trees or inside buildings. Modern receivers are much more sensitive.
It is very difficult to measure the signal level of a gps satellite without very expensive test gear (spectrum analyzer or specialized gps receiver). There are no commercially available tools to do this.
Why would you want to do this, anyway? The signal level is actually quite irrelevant in determining position.
