【中文标题】找不到提供程序类 SMACK 4.1.1 Android【英文标题】：Could not find provider class SMACK 4.1.1 Android 【发布时间】：2015-12-04 08:36:16 【问题描述】：

我是 android 开发和 Smack 的新手，我使用的是来自 link 的示例代码。但是当我尝试使用 smack 4.1.1 api 时，在低于 22 的 API 级别上运行应用程序时出现类未找到错误。

以下是我收到错误的代码部分：

    XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
            .builder(); // In this line 
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
    config.setServiceName(serverAddress);
    config.setHost(serverAddress);
    config.setPort(5222);
    config.setDebuggerEnabled(true);
    XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
    XMPPTCPConnection.setUseStreamManagementDefault(true);
    connection = new XMPPTCPConnection(config.build());
    XMPPConnectionListener connectionListener = new XMPPConnectionListener();
    connection.addConnectionListener(connectionListener);

这是我的 gradle 文件依赖列表：

dependencies 
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'

以下是我得到的错误：

编辑 1：在检查了大约 8-10 小时后，我发现问题出在 Smack 扩展库上。你能帮我解决这个问题吗？

【问题讨论】：

再次同步您的项目，然后再尝试。也为了开始 smack 我建议你使用这个网站：igniterealtime.org/builds/smack/docs/latest/documentation/… 并且只使用我说的库。这是我的依赖 smack 库： compile "org.igniterealtime.smack:smack-android-extensions:4.1.0" compile "org.igniterealtime.smack:smack-experimental:4.1.0" compile "org.igniterealtime.smack:smack -tcp:4.1.0" 感谢 Prerak，但我已经尝试同步项目，但仍然遇到同样的错误。我使用的其他库是appcompat、support和Using Glide to load image，我使用的其他库是谷歌提供的gson和play服务库。我也尝试删除它们，但仍然出现错误。 【参考方案1】：

最后我解决了这个问题。发布解决方案以帮助遇到同样问题的任何人。 smack 扩展库存在问题。如果将它们与 google play 服务库一起使用，则会在 KITKAT (api 19) 或以下设备的设备上引发错误。要让代码运行，请替换

compile 'com.google.android.gms:play-services:8.3.0'

使用您将要从播放服务中使用的库。就我而言，我需要 play 和 gcm 库。下面是他们的代码：

compile 'com.google.android.gms:play-services-gcm:8.3.0'
compile 'com.google.android.gms:play-services-plus:8.3.0'

以下是 google play 服务库的完整列表： https://developers.google.com/android/guides/setup
