This is how I calculate the AppWidget size:
protected Point getAppWidgetPixelSize (AppWidgetProviderInfo
appWidgetInfo, Point point) {
int cx = (appWidgetInfo.minWidth + 2) / 74;
int cy = (appWidgetInfo.minHeight + 2) / 74;
float density = getResources().getDisplayMetrics().density;
switch (getResources().getConfiguration().orientation) {
case Configuration.ORIENTATION_PORTRAIT:
point.x = (int)( 80 * cx * density + .5f);
point.y = (int)(100 * cy * density + .5f);
return point;
case Configuration.ORIENTATION_LANDSCAPE:
point.x = (int)(106 * cx * density + .5f);
point.y = (int)( 74 * cy * density +.5f);
return point;
//case Configuration.ORIENTATION_SQUARE:
//case Configuration.ORIENTATION_UNDEFINED:
default:
throw new IllegalStateException("orientation");
}
}
