GregorianCalendar cal = new GregorianCalendar(); Boolean b = cal.isLeapYear(2012); // true, Android example.
public class MainActivity extends Activity {
TextView txtV;
Context cntx;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtV = (TextView)findViewById(R.id.idLabel);
cntx = this;
StringBuilder strBuild = new StringBuilder();
GregorianCalendar cal = new GregorianCalendar();
Boolean b = cal.isLeapYear(2012); // true
strBuild.append("Is leap year 2012? " + b + "
");
b = cal.isLeapYear(2014); // false
strBuild.append("Is leap year 2014? " + b + "
");
txtV.setText(strBuild);

Put your sglite database to Android Eclipse project folder named Assets.
On device will copy database file to application folder as this example:
On device will copy database file to application folder as this example:
public void createDatabase(Context myContext) throws IOException {
String sPackName = myContext.getPackageName();
InputStream assetsDB = myContext.getAssets().open("myDatabase");
OutputStream dbOut = new FileOutputStream("/data/data/"+sPackName+"/database");
byte[] buffer = new byte[1024];
int length;
while ((length = assetsDB.read(buffer))>0){
dbOut.write(buffer, 0, length);
}
dbOut.flush();
dbOut.close();
assetsDB.close();

Important: Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB
Example of usage:
int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.layout.simple_list_item_activated_1 :
android.R.layout.simple_list_item_1;
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
getListView().setItemChecked(position, true);
Example of usage:
public void updateList() {
Context ctx = getActivity();
Notes notes = new Notes(ctx);
String[] from = { Notes.COLUMN_TITLE };
int[] to = { android.R.id.text1 };
int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.layout.simple_list_item_activated_1 : android.R.layout.simple_list_item_1;
ListAdapter adapter = new SimpleCursorAdapter(ctx,
layout, notes.getNotes(), from,
to, 0);
setListAdapter(adapter);
notes.close();
}
/..................
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Set the item as checked to be highlighted when in two-pane layout
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
getListView().setItemChecked(position, true);
}
First cteate big icon 512x512 px formtat .PGN in graphics editor as Photoshop, Gimp, Piant.NET and save image.
If you create new project via Eclipse and choice your 512x512 image for ic_launcher.
Eclipse will make all icons from this image for new application very well.
