android - 主屏幕应用程序快捷方式不适用于 android。应用程序未安装

Question

我在主屏幕上创建了应用程序快捷方式。但它不工作。它总是显示 toast app isn't installed。我尝试了 2 种不同的代码，但结果始终相同。

这是第一个代码

private void addShortcut() {
        // Adding shortcut on Home screen
        Intent shortcutIntent = new Intent(getApplicationContext(), MainActivity.class);
        shortcutIntent.setAction(Intent.ACTION_MAIN);
        Intent addIntent = new Intent();
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "AppName");
        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);
    }

第二个代码

public static void addShortcut(Context context)
    {
        Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

        ApplicationInfo appInfo = context.getApplicationInfo();

        // Shortcut name
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, "appInfo.name");
        shortcut.putExtra("duplicate", false); // Just create once

        // Setup activity shoud be shortcut object 
        ComponentName component = new ComponentName(appInfo.packageName, "MainActivity.class");
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(Intent.ACTION_MAIN).setComponent(component));

        // Set shortcut icon
        ShortcutIconResource iconResource = Intent.ShortcutIconResource.fromContext(context, appInfo.icon);
        shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);

        context.sendBroadcast(shortcut);
    }

我已经在带有 api 18 的模拟器和带有 android 4.2 的平板电脑上尝试了我的应用

任何帮助将不胜感激。谢谢

Answer 1

在我的例子中添加

android:exported="true"

从启动器调用的 MainActivity 有效。如果有帮助。
