应用程序图标未显示在应用程序中（在主屏幕上）

Question

My app used to work just fine, its icon displayed when installed in applications and it was uploaded to the Play Store. Now when I install it, it is like invisible, and in the Play Store it just says Uninstall, not open. What would be the reason for this?

Thanks.

Answer 1

This problem occurs when you include the <data> element in the same intent-filter as your action.MAIN, which does not expect any data. You could try splitting the intent-filter like this:

<activity
    android:name=".MainActivity"
    android:configChanges="orientation|screenSize"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <intent-filter>
        <action android:name="redacted.MainActivity" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="http"/>
        <data android:scheme="https"/>
        <action android:name="android.intent.action.VIEW" />
    </intent-filter>
</activity>
