当我使用Android Studio构建我的应用程序时，我遇到了这个错误。APK被编译，但当我试图在Android P模拟器上运行应用程序时，它会崩溃并抛出以下错误。详情请见附件:
java.lang.NoClassDefFoundError:failed resolution of :Lorg/apache/http/ProtocolVersion
这是我的身材。级文件。如果有人对问题有什么建议，我将不胜感激。多谢。

为了在Android 9.0中完美地运行org.apache.http.legacy，请创建一个xml文件res/xml/network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system" />
</trust-anchors>
</base-config>
</network-security-config>
在你的AndroidManifest.xml中添加2个标签
android: networkSecurityConfig = " @xml / network_security_config”
android: name = " org.apache.http.legacy "
<?xml version="1.0" encoding="utf-8"?>
<manifest......>
<application android:networkSecurityConfig="@xml/network_security_config">
<activity..../>
......
......
<uses-library
android:name="org.apache.http.legacy"
android:required="false"/>
</application>
还可以添加useLibrary ` org.apache.http。遗留'在你的应用程序构建gradle
android {
compileSdkVersion 28
defaultConfig {
applicationId "your application id"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
useLibrary 'org.apache.http.legacy'
