It means the &quot;loading amount&quot; is not measured.

From wiktionary:
Indeterminate: Not accurately determined or determinable.
It basically just means you&#39;re unsure how long the action will take so you cannot say for example something is 50% done.

This normally just means the progress will be displayed as a constantly moving loading bar rather than a percentage or the like.

Basically when `setProgressStyle(ProgressDialoge.STYLE_SPINNER)` is taken then `setIndeterminate()` will be true because a `circle(Spinner)` will rotate, which shows that &quot;do not know how much time it is going to take&quot;. When take `ProgressStyle(ProgressDialoge.STYLE_HORIZANTAL)` we will take `setIndeterminate()` as false since it take a value/percentage bar like how much percentage it was completed with `setProgress(value)`.


In simple language we can say when the amount is not determined means we don&#39;t know how much it gonna be to be completed or loaded fully..!!

&gt; Change the indeterminate mode for this ProgressDialog. In
&gt; indeterminate mode, the progress is ignored and the dialog shows an
&gt; infinite animation instead.
&gt; 
&gt; Note: A ProgressDialog with style STYLE_SPINNER is always
&gt; indeterminate and will ignore this setting.
&gt; Blockquote

For illustration, the progress animation keep loading from left to right and then repeat automatically without user interaction(which setProgress) when `indeterminate` set to `true`.

I am doing something like this...

    conn = sqlite3.connect(db_filename)

    with conn:
        cur = conn.cursor()
        cur.execute( ... )

`with` automatically commits the changes. But the docs say nothing about closing the connection. 

Actually I can use `conn` in later statements (which I have tested). Hence it seems that the context manager is not closing the connection.

Do I have to manually close the connection. What if I leave it open?

**EDIT**

My findings:

 - The **connection is not closed** in the context manager, I have tested and confirmed it. Upon `__exit__`, the context manager only commits the changes by doing `conn.commit()`
 - `with conn` and `with sqlite3.connect(db_filename) as conn` are same, so using either will still keep the connection alive
 - `with` statement does not create a new scope, hence all the variables created inside the suite of with will be accessible outside it
 - Finally, you should close the connection manually

I am developing my Android project, After I removed a unused library, I got the **error:**

    myproject/gen already exists but is not a source folder. Convert to a source folder or rename it

In my Activity code, all resources from `R.java` can not be resolved.


I tried, right click on my project =&gt; Java Build Path =&gt; under &quot;Source&quot; tab, I added gen/ as source. But it does not help with the problem...

Why, how to get rid of this problem?


----UPDATE----

I found that, the eclipse also complain that &quot;Project has no project.properties file! Edit the project properties to set one.&quot; , but I do have project.properties file under my project. Why it complains? I have cleaned the project and &quot;fix project properties&quot; but it does not help.

In my app there&#39;s a static variable that&#39;s being set to null when I return to my app from the external browser. Seems like the app or some portion of it is killed if the external web page I&#39;m launching is complex enough. 

If the app were to be killed entirely and then relauched from the main activity that would be ok, but the relaunch is from the activity that started the browser - and it&#39;s not meant to set the app state so it&#39;s crashing when accessing the null static variable. This is a one-out-of-six device problem for me so I need some advice.

Is there a flag to set to prevent this behavior?

    public class Utils {

            InputStream ims = assetManager.open(&quot;helloworld.txt&quot;);    
         }
    }

I am using this code trying to read a file from assets. I tried two ways to do this. First, when use `File` I received `FileNotFoundException`, when using `AssetManager getAssets()` method isn&#39;t recognized. 
Is there any solution here?

My problem is that when the activity is displayed, the ImageView has a padding at the top &amp; bottom. I&#39;ve confirmed it is the ImageView (by setting a background colour on the ImageView).

The image is 450x450px. Setting the height manually to 450px produces the desired effect (no padding), and setting it to 450dp produces the same effect as using wrap_content.

It seems that android is taking the height of the image (450px) and setting the height of the ImageView to the same value, but in dp.

Any ideas as to what I can do to fix this? I don&#39;t want to use absolute values as I&#39;ll be providing different images for different screen densities.

I made a stupid mistake by upgrading my SDK version to r15 as the android repository was not loading. How do I revert back to my older version r10? 
Or is sticking with the newer version better? I&#39;ll have to upgrade my ADT Plugin as well then. 
Thanks a lot.

I am developing an application that when the button is pressed, it opens a dialog with OK and Cancel buttons.

It works fine.

When the user presses the back button, I am handling this as follows

    {
        if ((keyCode == KeyEvent.KEYCODE_BACK)) 
    	{
    	
    	}
     return super.onKeyDown(keyCode, event);
    }

But the above method is not called. How can I handle this?

C# MessageBox dialog result

I am using **DialogFragments** for a number of things: choosing item from list, entering text. 

What is the best way to return a value (i.e. a string or an item from a list) back to the calling activity/fragment? 

Currently I am making the calling activity implement `DismissListener` and giving the DialogFragment a reference to the activity. The Dialog then calls the `OnDimiss` method in the activity and the activity grabs the result from the DialogFragment object. Very messy and it doesn&#39;t work on configuration change (orientation change) as the DialogFragment loses the reference to the activity. 

Thanks for any help.

Receive result from DialogFragment

I was going to use the following project: https://github.com/scottwis/OpenFileOrFolderDialog

However, there&#39;s a problem: it uses the `GetOpenFileName` function and `OPENFILENAME` structure. `OPENFILENAME` has the member named `templateID`, which is the identifier for dialog template. And the project contains the `res1.rc` file and the templated dialog init, too. But I couldn&#39;t figure out how to attach this file to my C# project.

Show ProgressDialog Android

I have a Fragment that can create and pop up a DialogFragment, but when I hit the back button, it dismisses the dialog even though I explicitly call setCancelable(false); Is there any way for my DialogFragment to be insensative to the back button?

    public class LoadingDialogFragment extends DialogFragment
    {
	    String title;
	    String msg;
	
	    public LoadingDialogFragment()
	    {
		    this.title = &quot;Loading...&quot;;
	    	this.msg = &quot;Please wait...&quot;;
	    }
	    public LoadingDialogFragment(String title, String msg)
	    {
		    this.title = title;
		    this.msg = msg;
	    }
	
	    @Override
	    public Dialog onCreateDialog(final Bundle savedInstanceState)
	    {
	        final ProgressDialog dialog = new ProgressDialog(getActivity());
	    
	        dialog.setTitle(title);
	        dialog.setMessage(msg);
	        dialog.setIndeterminate(true);
	        dialog.setCanceledOnTouchOutside(false);
	        dialog.setCancelable(false);
	    
	        return dialog;
	    }

    }

I create the DialogFragment from an AsyncTask:

    private class GpsTask extends AsyncTask&lt;String, Integer, Integer&gt;
	{
		//ProgressDialog dialog;
		@Override
		protected void onPreExecute()
		{
			FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
			DialogFragment newFragment = new LoadingDialogFragment(&quot;Gathering Location&quot;, &quot;Acquiring GPS lock...&quot;);
			ft.addToBackStack(null);
			newFragment.show(ft, &quot;dialog&quot;);
		}
		
		@Override
		protected Integer doInBackground(String... params)
		{
			//acquire a GPS lock and grab a few position updates
		}
		
		@Override
		protected void onProgressUpdate(Integer... input) { }
		
		@Override
		protected void onPostExecute(Integer result)
		{
			getSupportFragmentManager().popBackStackImmediate();
		}
	}
