Smack 4.1.8解析失败: Lorg/jivesoftware/smack/tcp/XMPPTCPConnectionConfiguration；

Question

我正在使用4.1.8库构建一个Smack客户端。代码编译得很好。当我运行时，应用程序崩溃并显示错误:由: Lorg/jivesoftware/smack/tcp/XMPPTCPConnectionConfiguration；引起: java.lang.NoClassDefFoundError:解析失败

我的导入行：

import org.jivesoftware.smack.*;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;
import org.jivesoftware.smackx.iqregister.AccountManager;

应用Gradle

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
    compile group: 'org.igniterealtime.smack', name: 'smack-extensions',     version: '4.1.8'
    compile group: 'org.igniterealtime.smack', name: 'smack-java7', version: '4.1.8'
    compile group: 'org.igniterealtime.smack', name: 'smack-tcp', version: '4.1.8'
    compile group: 'org.igniterealtime.smack', name: 'smack-core', version: '4.1.8'}

项目gradle

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

我也尝试将smack文件放在lib文件夹中，但得到了相同的错误。

Answer 1

你需要在你的gradle中添加更多的依赖，这对我来说很有效。

compile "org.igniterealtime.smack:smack-android:4.1.8"

compile "org.igniterealtime.smack:smack-tcp:4.1.8"

compile "org.igniterealtime.smack:smack-core:4.1.8"

compile "org.igniterealtime.smack:smack-im:4.1.8"

compile "org.jxmpp:jxmpp-jid:0.5.0-alpha6"

compile "org.igniterealtime.smack:smack-extensions:4.1.8"

Answer 2

尝试修改您的依赖关系：

compile "org.igniterealtime.smack:smack-android-extensions:4.1.8"
compile "org.igniterealtime.smack:smack-android:4.1.8"
compile "org.igniterealtime.smack:smack-tcp:4.1.8"
