Question

我的应用在Android 6以下崩溃。这是我的错误日志：

我的styles.xml：

<style name="AppTheme" parent="Theme.AppCompat">
    <item name="android:titleTextColor">@color/colorAccent</item>
    <item name="colorPrimary">@color/colorAccent</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

我的清单：

        android:theme="@style/Theme.AppCompat">
    <activity android:name=".Time" android:theme="@style/AppFullScreenTheme" android:label="Wysyłaj lokalizację czasowo"></activity>
    <activity android:name=".Settings"  android:theme="@style/AppFullScreenTheme" android:label="Ustawienia"/>
    <activity
        android:name=".MainActivity"
        android:theme="@style/AppFullScreenTheme">

我一直在寻找解决方案，但是它们对我没有用。我知道我可能必须更改样式中的某些内容，我尝试这样做，但是它仍然对我不起作用。谢谢

崩溃：您需要使用Theme.AppCompat主题
