我正在尝试创建一个可在云上连接的android应用程序。我大胆地尝试使用theyr api连接到koofr.eu。
Koofr是一种安全，简单的方法来存储，备份和共享您的照片，视频和文档。通过任何设备，无论何时何地，无论是计算机，电话还是平板电脑，都可以访问您的所有数据。安全与保障是我们软件和思维方式的核心。
他们提供的有关Java的文档很小，看起来很简单，但是库却很大。另外，我遇到的问题之一是该库使用了另外3-4个库来工作。
这是我的应用程序gradle的样子：
dependencies {
/*compile fileTree(dir: 'libs', include: ['*.jar']) */
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'net.koofr:java-koofr:1.2.8'
compile ("org.restlet.jse:org.restlet.ext.httpclient:2.1.2") {
exclude group: 'org.restlet', module: 'jse'
exclude group: 'org.restlet.ext', module: 'ss1'
}
compile 'org.apache.httpcomponents:httpclient:4.3.5'
compile 'org.restlet.jse:org.restlet.ext.jackson:2.1.2'
android {
packagingOptions {
exclude 'META-INF/DEPENDENCIES.txt'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/NOTICE'
exclude 'META-INF/LICENSE'
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/notice.txt'
exclude 'META-INF/license.txt'
exclude 'META-INF/dependencies.txt'
exclude 'META-INF/ASL2.0'
exclude 'META-INF/services/org.restlet.engine.ClientHelper'
}
}
在清单中，我添加了用户权限以允许应用程序中的Internet：
<uses-permission android:name="android.permission.INTERNET" />
我的主要活动代码很简单。
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
StorageApi api = DefaultClientFactory.create("app.koofr.eu", "*********", "******");
Log.i("TEST","User Info: "+api.getUserInfo());
} catch (StorageApiException e) {
e.printStackTrace();
Log.i("TEST","Mesaj: "+e.getMessage());
}
}
});
基本上，异常消息如下：
Internal Connector Error (1002) - The connector encountered an unexpected condition which prevented it from fulfilling the request
但这并没有以任何方式帮助我找到问题的解决方案，因此我发现了一些试图理解的警告。

如果有人有任何小的想法，我将不胜感激。谢谢。
最佳答案
android.os.NetworkOnMainThreadException
不要在UI线程上进行网络调用！
将可能会费时的所有内容放入新线程中，以免冻结UI。
