求助App is not indexable by Google Search; consider adding at least one Activity with an ACTION

加上 <action android:name="android.intent.action.VIEW">

<activity android:name=".MainActivity">
            <intent>
                <action android:name="android.intent.action.MAIN">
                <action android:name="android.intent.action.VIEW">
                <category android:name="android.intent.category.LAUNCHER">
            </intent>
        </activity>
