Android :: WifiManager.calculateSignalLevel - RSSI 5

May 20, 2010

I am trying to use the Wifimanager to calculate the Signal Level of the access points found during a scan.

I am using the following method:

WifiManager.calculateSignalLevel(int, int)

But it appears to always return the same int no matter what the RSSI level is.

Here is my code:.............

The logging outputs 1 for all the test cases for calculateQoS(int).

Am I missing something simple here? Why is the SignalLevel always 1?

Android :: 2.2 - Portable Hot Spot - WifiManager Class

Nov 9, 2010

I'm looking at how Android supports wifi portable hot spot functionality with a view to writing simple home screen widget that allows people to turn the phone's wifi hotspot on and off without digging into the device settings.

There was nothing obvious at developer.android.com so I dug through my copy of the Android source code and found that the WifiManager class (android.net.wifi.WifiManager) provides the basics to allow the state to be queried. So as well as 'getWifiState()' there is 'getWifiApState()' and a matching set of state constants.

However, in my bang-up-to-date Eclipse IDE, this class has none of the Ap methods or constants. Can anyone shed any light on this?

Android :: Get RSSI - To Get Bluetooth Signal Strength

Jan 27, 2010

I am working on Android platform 2.1 and trying to make an app that can get the Bluetooth signal strength from remote devices. It seems i should try to read the 'RSSI'

something like : int rssi = intent.getIntExtra (BluetoothDevice.EXTRA_RSSI, Integer.MIN_VALUE);

But it just keep returning the latter default value.

Did anyone ever manage to get the value of RSSI? Do we need to pair the device before getting the RSSI?

Android :: How Do I Poll RSSI Value Of An Existing Bluetooth Connection?

Jan 27, 2010

I need to know the signal strength of a Bluetooth connection to a remote device that I make with my Android 2.1 phone. From the SDK, I can see that I can determine the RSSI at the time I discover the remote device. But I can't see how to update that RSSI value over time.
Can someone give me a hand?

Android :: Cell RSSI - Network Signal Strength - On 1.5

Feb 16, 2010

Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5?

I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value.

Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

Android :: UMTS Signal Strength - RSCP Or RSSI

Sep 27, 2010

I need some clarification on API docs.

http://developer.android.com/reference/android/telephony/SignalStreng... getSignalStrength() indicates: "Get the GSM Signal Strength, valid values are (0-31, 99) as defined in TS 27.007 8.5"

[url] getRSSI() indicates "received signal strength or UNKNOWN_RSSI if unknown For GSM, it is in "asu" ranging from 0 to 31 (dBm = -113 + 2*asu) 0 means "-113 dBm or less" and 31 means "-51 dBm or greater" For UMTS, it is the Level index of CPICH RSCP defined in TS 25.125"

So, for 3G UMTS networks, does the SignalStrength class not return the same value as the NeighboringCellInfo class ? What are the chances that each RIL implementation is sending something different ?

Has anyone see negative value for signalStrength on UMTS networks as is possible for RSCP index values ?

RSSI - Application To Read Signal Strength Of 3G / GSM / WiFi

Mar 17, 2009

I'm developing an application to read signal strength of 3G, GSM, Wifi.

Is there any classes that provides us with the RSSI of 3G signal and GSM signal?

The WifiManager Class provides the RSSI for wifi, but I can't find any for 3G and GSM. If there is no classes provided, is it difficult to start from scratch?

Android :: How To Get Bluetooth RSSI On Android After Discovery

Jun 8, 2010

I'm trying to write a program that can read the signal strength of a bluetooth device linked to my android 2.0 handset. Doesnt seem like android exposes anyway to get the RSSI unless it is during discovery. Is there any other way to get the signal strength of the device after the device has been detected? I read of a way to do it using NDK to access the underlying BlueZ API, but I dont know how to use that. Any help would be appreciated.

Android :: Android IRC Office Hours - Android Bluetooth RSSI

Jan 27, 2010

I have a question about bluetooth RSSI functionality on the Android (either 2.0 or 2.1):

It's easy enough to get the RSSI value when a bluetooth connection is created, but how can you repeatedly get the RSSI value of a connection that is already active? It's really important to be able to do this, because this lets you determine if bluetooth devices are close to each other or far away, but I can't find any appropriate function calls in the Android API.

I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached it since it seems like I'm missing something:

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

Android :: Android WebView Not Loading A JavaScript File But Android Browser Loads It Fine

Jun 3, 2010

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class myKMB extends Activity {
I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.

Android :: Android - Add Menu Item To Android's Built-in Apps

Aug 17, 2009

I'd like to add a menu option to the Android camera app. Is this possible to do using the current SDK? I know I need to add an intent-filter tag in my activity. But I don't know what I should put in the mime type. I want to be able to process the live camera previews if the user selects the menu option. So what do I put into the type tag of the intent-filter? Also I suppose I won't be using ALTERNATIVE or SELECTED-ALTERNATIVE for the category as I want to deal with the whole intent?

Android :: Moto Android Stuck On Android Splash Screen

Feb 5, 2010

I am having a bit of a problem with my Android. So what happened was I downloaded "DroidRootPro" from the market. I rooted my phone with this, installed the 800MHZ ROM image, rebooted and the phone came up great. I was actually surprised on how fast it became. Once the phone came back up, I tried installing one of the custom themes that came with that app (I know I should have left it alone). The phone than rebooted and I was never able to bring it back up. It gets stuck in this endless loop where it tries to boot but doesn�t get past the "Droid" splash screen, it just keeps rebooting every time.

Things I have tried:

-Wipe data/factory reset (in recovery mode), no go.
-Wipe cach partition, no go
-Restore from a "nandroid" backup, no go. I tried pretty much every combination of restores and am unable to bring the phone up.

Is there anyway I can download the factory image that comes with the phone, put it on an SD card and restore to that? I have looked all over but cant find any information on this.

Android :: How To Reference R.java Of Other Apps In Android - Like Com.android.music

Sep 29, 2010

I am trying to develop an app to supplement the built-in music player. I've used git to download the com.android.music package and looked around at its code. I can launch the music player by copying some of its code and launching activities with intents.

Now what I need to do is get a handle to its current view. In the MusicUtils.java file, I see a line that says

View nowPlayingView = a.findViewById(R.id.nowplaying);

I'd like to do the same thing. Only I don't have access to the R.java file, so I can't write e.g. R.id.nowplaying. How do I do this? How do I reference the music players R.java? I do know the R.java stuff is declared public so that shouldn't be a problem. Right?

Is it even possible? I saw this related question and am now wondering: http://stackoverflow.com/questions/2437271/how-to-load-com-android-music-code-into-eclipse-and-compile

I'm working against the Android 2.2 SDK, but it'd be helpful to know if the answer is different for older versions such as 1.5.
