IBM Worklight - Unable to get network signal strength in Android

Question

Below is my Java implementation. The idea is to display myUtilString in an edit text in order to see the signal strength in a Hybrid android app while in a WL.N

Answer 1

Do you get any errors either in Eclipse console or in the LogCat view? Provide the output from LogCat, that should help. Edit the question with this information.

The following permission needs to be added to AndroidManifest.xml as well:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Edit:
There is also the following tutorial to get signal strength: http://www.firstdroid.com/2010/05/12/get-provider-gsm-signal-strength/

I've followed it, and it worked for me in the Android emulator.
This is my Java implementation:

package com.testapp;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.SignalStrength;
import android.telephony.TelephonyManager;
import android.widget.Toast;

public class HelloNative extends Activity {

    TelephonyManager        tm;
    MyPhoneStateListener    MyListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        MyListener   = new MyPhoneStateListener();
        tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
        tm.listen(MyListener ,PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);

        LinearLayout linearLayout = new LinearLayout(this);
        linearLayout.setOrientation(LinearLayout.VERTICAL);
        setContentView(linearLayout);

        Button submitButton = new Button(this);
        submitButton.setText("Return to the Web App");
        submitButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                setResult(RESULT_OK);
                finish();
            };
        });

        linearLayout.addView(submitButton);
    }

    private class MyPhoneStateListener extends PhoneStateListener
    {
      /* Get the Signal strength from the provider, each time there is an update */
      @Override
      public void onSignalStrengthsChanged(SignalStrength signalStrength)
      {
         super.onSignalStrengthsChanged(signalStrength);
         Toast.makeText(getApplicationContext(), "Signal strength is: "
            + String.valueOf(signalStrength.getGsmSignalStrength()), Toast.LENGTH_SHORT).show();
      }

    };

}
