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

As for all those who are waiting for updates on my side open source projects.

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.
