&gt; is it bad form to call stopSelf() while inside a onStartCommand() method?

Off the top of my head, I can&#39;t think of why that would be a problem.

`stopSelf()`, like a lot of stuff in Android, has no immediate effect. It puts a message on the message queue processed by the main application thread. The actual work of stopping the service will not even begin until sometime after `onStartCommand()` has returned.

I would like to hide the Android virtual keyboard in JavaScript.  Someone suggested doing [this](https://stackoverflow.com/questions/7045889/how-to-hide-keyboard-on-phonegap-android):

    $(&#39;#input&#39;).focus(function() {
      this.blur();
    });

But this doesn&#39;t work if the keyboard is already visible.  Is this something that can be done?

How can I hide the Android keyboard using JavaScript?

I have a &quot;duration&quot; column in an Excel sheet. Its cell format always changes &amp;mdash; I want convert the duration from minutes to seconds, but because of the cell formatting it always gives me different answers. 
                                     
I was thinking that before doing the conversion I could convert that cell format to text so that it will consider that as text value and not try to auto-format it.

Currently I am copying all data into Notepad and then saving it back to the Excel sheet to remove all of the previous format. Is there a way to automate setting a cell&#39;s formatting to text using VBA?

There are some conditions where my service could be attempted to be started when it should not be. In cases like this is it bad form to call `stopSelf()` while inside a `onStartCommand()` method? If so what is the best way to handle such a situation? Any resources will be greatly appreciated.

I have an Activity with ActionBar and tab navigation. I am using the split mode, so the tabs are at the top and actions are in the bottom bar. How can I dynamically change the bottom actions? I need this because every tab has different actions.

I would like to finish an activity from inside the `onCreate` method. When I call `finish()`, `onDestroy()` is not immediately called, the code keeps flowing past `finish()`. `onDestroy()` isn&#39;t called until after the `onCreate()` closing brace.

Per the `onCreate()` description at developer.android.com/reference.

&gt; You can call finish() from within this function, in which case
&gt; onDestroy() will be immediately called without any of the rest of the
&gt; activity lifecycle (onStart(), onResume(), onPause(), etc) executing.

Reason I ask is: I would like to check data from the Bundle passed to `onCreate()`. Of course I have control of what is passed to `onCreate`, but I still think it should be checked at the point of delivery.

My code contains class `A`, which starts Activity `B`. I believe the last two &quot;outside of if clause&quot; tags, shouldn&#39;t be called because the `finish` method in the `if` statement should have destroyed the activity.  It has nothing to do with the if clause because the tag line after the second `finish()` call is still also read.

My Code:

Class A

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
            
        // goToBButton: when pressed sends message to class B.    
        Button goToBButton = (Button)this.findViewById(R.id.go_to__b_btn);
        goToBButton.setOnClickListener(new OnClickListener() {
        	@Override
            public void onClick (View v) {    	
        		Log.i(TAG,&quot;A Class: goToBButton, onClick&quot;);
        		Intent i = new Intent(A.this, B.class);
      			startActivityForResult(i,REQ_TO_B);
        	}     	
        });                
    } // end onCreate

My Code ClassB

        public class B extends Activity{

	private static final String TAG = &quot;tag&quot;;
	
	@Override
       public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.layoutb);
      
      // set as true, should always print Tag: one line before first finish&quot;
      if (true)  {
      	
      	Log.i(TAG,&quot;B Class: one line before 1st finish&quot;);
        finish();
      }
       
      // shouldn&#39;t get here after first finish
      Log.i(TAG,&quot;B Class: outside of if clause, before second finish&quot;);
      finish();
      // shouldn&#39;t get here after second finish
      Log.i(TAG,&quot;B Class: outside of if clause, after finish&quot;);                  
       } // end onCreate
	

	@Override
	public void onStart () {
		super.onStart();
		Log.i(TAG,&quot;B Class: onStart&quot;);
	}
	
	@Override
	public void onRestart() {
		super.onRestart();
		Log.i(TAG,&quot;B Class: onRestart&quot;);
	}
	
	@Override
	public void onResume () {
		super.onResume();
		Log.i(TAG,&quot;B Class: onResume&quot;);
	}
	
	@Override
	public void onPause () {
		super.onPause();
		Log.i(TAG,&quot;B Class: onPause&quot;);
	}
	
	@Override
	public void onStop () {
		super.onStop();
		Log.i(TAG,&quot;B Class: onStop&quot;);
	}
	
	@Override
	public void onDestroy () {
		super.onDestroy();
		Log.i(TAG,&quot;B Class: onDestroy&quot;);
	}
	
     } // end B Class

Here are the results of my tags:

&gt; 11-26 15:53:40.456: INFO/tag(699): A Class: goToBButton, onClick
&gt; 
&gt; 11-26 15:53:40.636: INFO/tag(699): A Class: onPause
&gt; 
&gt; 11-26 15:53:40.865: INFO/tag(699): B Class: one line before 1st finish

&gt; 11-26 15:53:40.896: INFO/tag(699): B Class: outside of if clause,
&gt; before second finish
&gt;

&gt;

I am using this example below. But when I move my fingers too fast across the screen the line turns to individual dots.

I am not sure whether I can speed up the drawing. Or I should connect the two last points with a straight line. The second of these two solutions seems like a good option, except when moving your finger very fast you will have long sections of a straight line then sharp curves.

If there are any other solutions it would be great to hear them.

Thanks for any help in advance.

Is there any other reason that the Intent that is passed to `onStartCommand(Intent, int, int)` would be NULL besides the system restarting the service via a flag such as `START_STICKY`?

Also, when the service is restarted by the system the `Intent.getAction()` method returns NULL... sometimes. Intent is not NULL just `getAction()`

I asked [here][1] too but haven&#39;t received an answer just yet.

**UPDATE**: After chatting with Mark Murphy, he suggested that I return `START_REDELIVER_INTENT` in the `onStartCommand()` callback in my service instead of `START_STICKY` so that the entire intent is sent following a restart. 

I didn&#39;t do this initially because I was concerned that if the service was attempting to do something, then in the middle of that something the service was restarted... will it recognize that it started doing that something? I guess that is logic I will need to be responsible for :)

I am trying to start up a `BroadcastReceiver` within a `Service`. What I am trying to do is have a background running `service` going that collects incoming text messages, and logs incoming phone calls. I figured the best way to go about this is to have a `service` running that incorporates a broadcast receiver that can catalog either. 

How do i go about doing this? I already have my service up and running.

I have been working on an Android app using Phonegap and now would like to make it so when the app is closed it can still execute the java/js code in the app. So I understand I need to create a service. If I create a service plugin on phonegap can I still execute the javascript code or only the java?

Has anyone does something like this? I found this discussion but did not seem to work: http://groups.google.com/group/phonegap/browse_thread/thread/722b0e796baa7fc6
So that is all I have right now.

Before I turn to developing it native if I can&#39;t figure it out thought I would ask if anyone has done this before. I can&#39;t seem to find any of the phonegap plugins that do something similar. 

EDIT: I have got an app that executes Java code as a service. However when it calls sendjavascript it does not work. So is there a way to have the javascript code running in the background as well when an app is closed with phonegap?

Thanks

Creating an Android Service with Phonegap? (Have phonegap app run even when closed)

I created a service that is bound by other applications through AIDL, and I add it to the manifest as follows:

    &lt;service android:name=&quot;.MyService&quot;&gt;
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;org.example.android.myservicedemo.IService&quot; /&gt;
        &lt;/intent-filter&gt;
    &lt;/service&gt;

where IService is the AIDL interface.

In this way, Eclipse show me the warning *Exported service does not require permission*. If I remove the `intent-filter`, the warning disappear, but obviously the applications are unable to bind to the service.

What does this warning mean?
