Question

我有问题。我生成并安装了已签名的apk但是我无法启动应用程序安装，我无法在应用程序菜单中看到它。我只能在设置应用菜单中看到它。为什么我看不到或开始？该应用程序可以通过调试器启动。你能救我吗？

操作系统是Android 7和5。

更新我发现了问题，它是android：mimeType但为什么？你能解释一下吗？

Answer 1

您可能忘记了启动模式。在应用程序元素

中的AndroidManifest.xml中写下这个

<activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>

将.MainActivity替换为您的活动名称

为什么我的应用程序无法启动或查看App菜单？
