我在上面改进了一点解决方案.现在,它会保存首选项是否已添加快捷方式,如果用户将其删除,则不会在应用程序的新启动中添加快捷方式.这也节省了一点时间,因为添加现有快捷方式的代码不再运行.
final static public String PREFS_NAME = "PREFS_NAME";
final static private String PREF_KEY_SHORTCUT_ADDED = "PREF_KEY_SHORTCUT_ADDED";
// Creates shortcut on Android widget screen
private void createShortcutIcon(){
// Checking if ShortCut was already added
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
boolean shortCutWasAlreadyAdded = sharedPreferences.getBoolean(PREF_KEY_SHORTCUT_ADDED, false);
if (shortCutWasAlreadyAdded) return;
Intent shortcutIntent = new Intent(getApplicationContext(), IntroActivity.class);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "YourAppName");
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(getApplicationContext(), R.drawable.ic_launcher));
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(addIntent);
// Remembering that ShortCut was already added
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean(PREF_KEY_SHORTCUT_ADDED, true);
mit();
}
