Startup Weekend: An Overview

Startup Weekend is a non-profit organization based out of Seattle, WA USA. We consist of a small full time staff of eight along with community leaders in cities all over the globe. Startup Weekend’s primary mission is to be the most valuable and influential organization in startup communities around the world. Startup Weekend doesn’t have to teach entrepreneurship in a boring classroom setting, we model it in a fun, interactive, and results driven way. As a result, we have become one of the leading catalysts for startup creation, co-founder dating, and entrepreneurship education in startup ecosystems around the world.

1. In space: In space, accelerometer, compass and GPS will not work. because accelerometer and compass have required gravity and magnetic field respectively. But when we use accelerometer and compass nearer any planet, then we get relative values as that planet’s field with some accuracy. and GPS will not work, if we are close to any other planet excluding earth. Because for GPS usage, we require human invented working satellites.

2. On any other planet (excluding earth): Still GPS will not work in any other planet. and we get relative values of accelerometer and compass as that planet.

3. On center of gravity of earth: We cannot predict results for accelerometer and GPS. It is possible that we get garbage values for accelerometer. and compass will work proper because location of center of gravity and location of center of magnetic field of earth are different.

4. On center of magnetic field of earth: In this case, we get garbage values for compass and get proper values for accelerometer and GPS. But still It is possible that if there is any relationship between gravity and magnetic field, then we get unknown results for accelerometer.

For all those cases, I expect results based on physics theories, but still we cannot guess exact results. Those all will work on so many parameters, planet atmosphere and other theories.

SQLite provides three simple methods in SQLiteDatabase class :
beginTransaction();
setTransactionSuccessful();
endTransaction();

These methods can be used to make all the insert calls in the same batch in a single transaction. Transactions are used when there is a need to perform a series of queries that either all complete or all fail. When a SQLite transaction fails an exception will be thrown. Start a transaction by calling the beginTransaction() method. Perform the database operations and then call the setTransactionSuccessful() to commit the transaction. Once the transaction is complete call the endTransaction() function.

A sample example code is shown below:

// Begin the transaction
db.beginTransaction();
try{
for each record in the list{
ContentValues contentValues=new ContentValues();
contentValues.put(COLUMN_NAME,record);
db.insert(TABLE_NAME,null,contentValues);

}
// Transaction is successful and all the records have been inserted
db.setTransactionSuccessful();
}catch(Exception e){
Log.e(“Error in transaction”,e.toString());
}finally{
//End the transaction
db.endTransaction();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_menu, menu);

getLayoutInflater().setFactory(new Factory() {
@Override
public View onCreateView(String name, Context context,
AttributeSet attrs) {

if (name .equalsIgnoreCase(“com.android.internal.view.menu.IconMenuItemView”)) {
try {
LayoutInflater f = getLayoutInflater();
final View view = f.createView(name, null, attrs);

new Handler().post(new Runnable() {
public void run() {

// set the background drawable
view .setBackgroundResource(R.drawable.my_ac_menu_background);

// set the text color
((TextView) view).setTextColor(Color.WHITE);
}
});
return view;
} catch (InflateException e) {
} catch (ClassNotFoundException e) {
}
}
return null;
}
});
return super.onCreateOptionsMenu(menu);
}

setBackgroundColor (int color)

What one must note is if the HTML contains a value for the background it will override the color we set. The same is true for the foreground color too.

For the foreground color we make use of CSS to set the color and add it to the content we want to display in a div element wrapping the html we need to display. Here is the sample code

private final String htmlbegin = "<div style=\"color:#FFFFFF ;  \">";
private final String htmlend = " </div>";
private final String htmlBody = "<p>Summary</p>"
	+ "<p>Strong text</strong> Somemore text"
	+ "and the final line</p>";
WebView body;

@Override
public void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.main);

	body = (WebView) findViewById(R.id.message_body);
	body.setBackgroundColor(0);

	// body.setDef
	body.loadDataWithBaseURL("", htmlbegin + htmlBody + htmlend,
		"text/html", "utf-8", "");
}

As I stated before any css inside the html will override our css settings.
