Android AppWidget TableLayout

As most developers have found out, appwidgets break the normal rules when it comes to widget development.
Due to the abstract class ( appwidgetProvider ) and the updating through RemoteViews

You’re quite limited in the use of the different layout controls that are available.
namely :

  • FrameLayout
  • LinearLayout
  • RelativeLayout

So how do we get a table layout, that automatically expands or fills the available space?

The answer is clever use of of the weight attributes of linearLayout and the children components.
Here is an example of a timetable.

9 – 6 / Mon – friday.

Note* i have an image up the top right, you may wont to replace this with something else!

Scroll to the end for an example on how to loop through the cells

And just in case your wondering how you can easily loop through them

RemoteViews views = new RemoteViews( context.getPackageName() , R.layout.widget );

for ( int i = 9 ; i < 18 ; i++ )
{
	try
	{
	        int monid = R.id.class.getField( "mon" + i ).getInt( 0 );
		views.setOnClickPendingIntent( monid , this.createOnClickPendingIntent( context ) );

		int tueid = R.id.class.getField( "tue" + i ).getInt( 0 );
		views.setOnClickPendingIntent( tueid , this.createOnClickPendingIntent( context ) );

		int wedid = R.id.class.getField( "wed" + i ).getInt( 0 );
		views.setOnClickPendingIntent( wedid , this.createOnClickPendingIntent( context ) );

		int thuid = R.id.class.getField( "thu" + i ).getInt( 0 );
		views.setOnClickPendingIntent( thuid , this.createOnClickPendingIntent( context ) );

		int friid = R.id.class.getField( "fri" + i ).getInt( 0 );
		views.setOnClickPendingIntent( friid , this.createOnClickPendingIntent( context ) );

		Log.e( "done" , "Hour : " + i );
	}
	catch ( Exception k )
	{
		Log.e( "ffdsfdsfs" , "ERROR : " + k.getMessage() );
	}
}

Android Custom Toast View from Service

Android documentation is something to be desired ;).

Given the following tutorial on creating Custom Toast Notifications.
Toast Notifications

They neglect to say how to do it from a service!

LayoutInflater inflater = ( LayoutInflater ) getSystemService( LAYOUT_INFLATER_SERVICE );
View layout = inflater.inflate( R.layout.toastview , null );

ImageView image = ( ImageView ) layout.findViewById( R.id.image );
image.setImageResource( R.drawable.meteor );
TextView text = ( TextView ) layout.findViewById( R.id.text );
text.setText( this.client.getLastError() );

Toast toast = new Toast( getApplicationContext() );
toast.setGravity( Gravity.CENTER_VERTICAL , 0 , 0 );
toast.setDuration( Toast.LENGTH_LONG );
toast.setView( layout );
toast.show();

Chrome Linux Save Flash Files

So i came across this handy scripts.

As part of some new offensive ;), or maybe just privacy concerns for the user.
Flash now right after beginning a FLV download
deletes the file from the /tmp directory

As it still has a lock on the file descriptor, it disappears right after the flash player closes.

Let the video finish streaming and then run this script
It will save the deleted flv videos with open file descriptors into the folder where you have run the script.

Take advantage of those 300 texts that are sitting there for free!

You know what i mean, meteor is horrible for managing contacts etc.
With this app, you can do it from the comfort of your desktop!

  • Shows a dropdownlist of your contacts
  • Imports contacts from CSV
  • Multiple recipients

Android API & Java

So I’m kinda pissed

I bought a new Android HTC Desire HD which I’m fairly happy with.

I bought it with the intent of developing an application over the next year as part of my FYP for college.
During my dabbling in the first few hours, I began to realize why I hate Java and its every growing obscure complexity.

Lets look at 3 separate blunders from a fundamental level, in learning this new technology.

1.

First of all, lets leave Java aside a moment and focus on the Android.
intent, view, remoteview, activity, context, ApplicationContext, ActionBar, Fragment, IntentService, ListActivity …

If your a programmer and never looked at the Android API your probably wondering what these mean exactly?
EXACTLY – epic fail number one, this is the type of stuff you would expect from the Java community,
bizarre names to describe b****y windows and controls!

Coming from the Linux world i have no problem with odd programs with odd names, you get quiet used to it.  But to be fair in a programming world, the concepts, techniques etc are all the same regardless of the language.

That said, why change the name of Window / Frame / whatever to Activity, an activity could mean 200 bloody things!

From the Android API
” An activity is a single, focused thing that the user can do. Almost all activities interact with the user,
so the Activity class takes care of creating a window for you in which you can place your UI with setContentView(View). “

It’s a f******g window, why oh why did you have to go with these bizarre names,
as you get further into the API the names just get weired and weirder, its like learning French, who cares about French! This reminds me of SOAP in Java, JAX-WS, POJO, SEI, WSDL, GlassFish
and the list goes on with every increasing obscurity to define very simple web concepts.

2.

One more thing on Android API that i really wish they would get rid of
‘@‘ what about @?

As you start too look through the Java XML files, you start seeing all these @’s’
Soon enough, after some files, you realize that the @ symbol is some whatever overloaded depending on the context.

One moment its referencing a string element and in another an actual XML file.
As your code is ever growing, you start to see @‘s all over the place.
Your following @‘s along and by the time to find what exactly you’ve been trying to figure out,
You can’t remember were you were @.

3.
