android闪退

[hongjie104]

在执行这个方法的时候 X5Sdk.openWebActivity(url, title: title); 闪退了~
报错如下

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xingfei.ui/com.cjx.x5_webview.X5WebViewActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference

求指导

检查你android values下的 style 是否为noactionbar

[VenusCao]

还有不要使用AppCompat下的主题

[hongjie104]

noactionbar

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

style用的都是默认的，并没有做过任何修改

[VenusCao]

示例app会出现么

[hongjie104]

示例app会出现么

示例APP我手机装了，X5Sdk.openWebActivity 访问百度，算是正常吧，只是偶尔会出现错误提示，应该是因为百度页面里有下载百度app的链接导致。但是不会崩溃

[VenusCao]

那可能就是sdk版本的问题，你可以对照demo的bulid.gradle调整

[hongjie104]

额，我看了一下，demo和我的工程里的gradle都是3.2.1

[VenusCao]

android sdk,不是gradle

[hongjie104]

compileSdkVersion 和 targetSdkVersion 都设置成和demo一样的28了，错误依旧~

[VenusCao]

那你等下，我看看怎么调整一下

[VenusCao]

反正就是找不到actionbar，你把style改成有actionbar的主题试试，下个版本我处理一下

[VenusCao]

Theme.Black.NoTitleBar 改成 Theme.Black

[hongjie104]

好，多谢

[VenusCao]

试试新版本0.1.3

[hongjie104]

试试新版本0.1.3

新版本不会闪退了，非常感谢
