Question

我已将Android应用程序从26个SDK升级到了28个。

它在23-27版本中很好用。

但是新版本将在SDK 28中崩溃。

这是异常堆栈：

请帮助我。

Answer 1

如果您使用的是Apache HTTP客户端，请在AndroidManifest.xml中添加以下内容： refer this

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Answer 2

您可以在模块的 build.gradle 中添加以下行：

class="phone_mobile"

并且不要忘记将 minSdkVersion 升级到 23 ，如以下链接所示：

java.lang.NoClassDefFoundError：无法解决以下问题：Lorg / apache / http / params / BasicHttpParams;
