建立，刪除快捷圖示shortcut android .

在manifest.xml中，新增許可權：

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

程式碼如下：

	private void uninstallShortcut(){
		 Intent shortcut = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");  
		 							 //com.android.launcher.action.UNINSTALL_SHORTCUT
         
		    //快捷方式的名稱     
		    shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));     
		    shortcut.putExtra("duplicate", false); 
		    Intent intent = new Intent(Intent.ACTION_MAIN);
		    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
		    
		    intent.setClass(getApplicationContext(), MainActivity.class);
		   
		    shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT,intent);     
		             
		    sendBroadcast(shortcut);     
	}
	
	private void installShortcut(){
		Log.i("CreateShortcutActivity","onclick to create shortcut");
		Intent shortcutIntent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
		shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME,getString(R.string.app_name));
		shortcutIntent.putExtra("duplicate", false);
		Intent intent = new Intent(Intent.ACTION_MAIN);
		intent.setClass(getApplicationContext(), MainActivity.class);

		shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, intent);
		shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
				Intent.ShortcutIconResource.fromContext(CreateShortcutActivity.this,
						R.drawable.ic_shortcut));
		sendBroadcast(shortcutIntent);
	}

在android中，有InstallShortcutReceiver,和UninstallShortcutReceiver兩個類，用來接收該廣播。

注意：shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, intent);

在InstallShortcutReceiver中，如果intent沒有設定action的話，會新增Intent.ACTION_VIEW，造成在Remove shortcut的時候，比較兩個Intent時，可能不一致而無法刪除該shortcut.

所以，建議要自己新增ACTION.

附上android Intent.filterEquals().就是這方法用來比較前後兩個Intent的，

  /**
     * Determine if two intents are the same for the purposes of intent
     * resolution (filtering). That is, if their action, data, type,
     * class, and categories are the same.  This does <em>not</em> compare
     * any extra data included in the intents.
     *
     * @param other The other Intent to compare against.
     *
     * @return Returns true if action, data, type, class, and categories
     *         are the same.
     */
    public boolean filterEquals(Intent other) {
        if (other == null) {
            return false;
        }
        if (mAction != other.mAction) {
            if (mAction != null) {
                if (!mAction.equals(other.mAction)) {
                    return false;
                }
            } else {
                if (!other.mAction.equals(mAction)) {
                    return false;
                }
            }
        }
        if (mData != other.mData) {

        if (mPackage != other.mPackage) {
            if (mPackage != null) {

                    return false;
                }
            } else {
                if (!other.mComponent.equals(mComponent)) {
                    return false;
                }
            }
        }
        if (mCategories != other.mCategories) {
            if (mCategories != null) {
                if (!mCategories.equals(other.mCategories)) {
                    return false;
                }
            } else {
                if (!other.mCategories.equals(mCategories)) {
                    return false;
                }

可見，flag屬性是不在比較之列的，可以任意新增
