android桌面快捷方式的创建和查询
桌面快捷方式的创建

// 内置的在2.1上不行
// Intent intent = new Intent(Intent.ACTION_CREATE_SHORTCUT);
Intent intent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
intent.putExtra("duplicate", false);
ComponentName comp = new ComponentName(getApplicationContext(), Shortcut.class);
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT,
		new Intent(Intent.ACTION_MAIN).setComponent(comp));
ShortcutIconResource res = Intent.ShortcutIconResource.fromContext(
		getApplicationContext(), R.drawable.icon);
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, res);
sendBroadcast(intent);

桌面快捷方式的查询

private static final Uri CONTENT_URI = 
	Uri.parse("content://com.android.launcher.settings/favorites?notify=true");

private static final String[] PROJECTION = {
	"_id",
	"title",
	"iconResource"
};

private boolean hasShortCut() {
	ContentResolver resolver = getContentResolver();
	Cursor cursor = resolver.query(CONTENT_URI, PROJECTION, "title=?",
			new String[] {getString(R.string.app_name)}, null);

	if (cursor != null && cursor.moveToFirst()) {
		cursor.close();
		return true;
	}

	return false;
}

快捷方式的删除（2.1上不行），当程序删除时，系统会自动帮我们把快捷方式删除

Intent intent = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
ComponentName comp = new ComponentName(getApplicationContext(), Shortcut.class);
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT,
		new Intent(Intent.ACTION_MAIN).setComponent(comp));
sendBroadcast(intent);
