Question

I see the following error in DDMS when trying to use a CheckBox on my MyActivity” activity to start a service called “MyService”:

W/ActivityManager(   73): Unable to start service Intent { cmp=com.example.android.myprogram/.MyService }: not found

I used the tutorial http://developer.android.com/resources/tutorials/views/hello-formstuff.html and added the provided code to the end of my onCreate() method. I have the classes specified separately in MyActivity.java and MyService.java.

package com.example.android.myprogram;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;


public class MyActivity extends Activity {
    private static final String TAG = "MyActivity";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final CheckBox checkbox = (CheckBox) findViewById(R.id.checkbox);
        checkbox.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Perform action on clicks, depending on whether it's now checked
                if (((CheckBox) v).isChecked()) {
                    // TODO: Add code to START the service
                    Log.d(TAG, "startService from checkbox");     
                    startService(new Intent(MyActivity.this, MyService.class));
                } else {
                    // TODO: Add code to STOP the service
                    Log.d(TAG, "stopService from checkbox");     
                    stopService(new Intent(MyActivity.this, MyService.class));
                }
            }
        });
    }
}

My manifest file does have the following in which I’ve also tried the full namespace, short name, using an intent-filter per another search, etc. I’m not saying what is there is correct. I just left it at a stopping point.

<service android:name=".MyService">
   <intent-filter><action android:name="com.example.android.myprogram.MyService"></action>
   </intent-filter>
</service>

And lastly, my service which I’ve decided to break down to it’s bare minimum:

package com.example.android.myprogram;


import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;

public class MyService extends Service {
    private static final String TAG = "MyService";

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        Log.d(TAG, "onCreate");
        //code to execute when the service is first created
    }

    @Override
    public void onDestroy() {
        Log.d(TAG, "onDestroy");
        //code to execute when the service is shutting down
    }

    @Override
    public void onStart(Intent intent, int startid) {
        Log.d(TAG, "onStart");
        //code to execute when the service is starting up
    }
}

I’m very, very, very new to Java/Android programming and programming in general (but learning) so I’m sure this is user error and probably common sense to everyone else. Any suggestions would be great.

I kept digging around and, as I figured, I was making an obvious rookie error. In AndroidManifest.xml, I had the < service> declaration after < application> instead of nested inside it.
