从主屏幕卸载Android应用程序时，应用程序启动图标不会被删除 [英] Application launcher icon is not deleted from Home screen when uninstalling android app

问题描述

我使用了一个类似的codesnippet如下图所示添加主屏幕上的应用程序快捷方式：

I'm using a similar codesnippet as shown below to add an application shortcut on the homescreen:

    Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
    shortcutIntent.setClassName(this, this.getClass().getName());
    shortcutIntent.putExtra(EXTRA_KEY, "ApiDemos Provided This Shortcut");

    // Then, set up the container intent (the response to the caller)

    Intent intent = new Intent();
    intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.shortcut_name));
    Parcelable iconResource = Intent.ShortcutIconResource.fromContext(
            this,  R.drawable.app_sample_code);
    intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);

    // Now, return the result to the launcher

    setResult(RESULT_OK, intent);

有与创建快捷方式，但在卸载应用程序时，该快捷方式仍保留在主屏幕没有问题。当卸载其他应用程序，他们似乎都还删除其对应的主屏幕上的快捷方式。这是我尝试才达到我的创建逐code-快捷方式图标

There is no problem with creating the shortcut, but when uninstalling the app, the shortcut remains on the homescreen. When uninstalling other apps they all seem to also remove their corresponding homescreen shortcuts. This is what i try to achive with my "created-by-code-shortcut-icon"

是否有你的Andr​​oid专家在这里的＃1知道什么是需要从主屏幕删除应用程序快捷方式，当应用程序被卸载？

推荐答案

我觉得你可以尝试把这个动作在第二个意图：com.android.launcher.action.INSTALL_SHORTCUT

I think you can try putting this action in the second Intent: "com.android.launcher.action.INSTALL_SHORTCUT"

这工作对我来说，启动图标被安装在主屏幕上，当我卸载应用程序，该图标就会消失。一直在挣扎了一段时间与此有关。

This works for me, the launcher icon gets installed on the home screen, and when I uninstall the application, the icon is removed. Have been struggling some time with this.

Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
shortcutIntent.setClassName(this, this.getClass().getName());

Intent intent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
Parcelable iconResource = Intent.ShortcutIconResource.fromContext(
            this,  R.drawable.launcher_icon);
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
sendBroadcast(intent);

希望这有助于。
