当我尝试运行我的应用程序时出现此错误：
Information:Gradle tasks [:app:assembleDebug]
Warning:Dependency org.apache.httpcomponents:httpclient:4.3.5 is ignored for debug as it may be conflicting with the internal version provided by Android.
In case of problem, please repackage it with jarjar to change the class packages

You can ignore those files in your build.gradle:
android {
packagingOptions {
exclude 'META-INF/NOTICE'
}
}
Error:Execution failed for task ':app:packageDebug'.

这是我的build.gradle：
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "..."
minSdkVersion 14
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:support-v4:22.0.0'
compile 'com.squareup.retrofit:retrofit:1.9.0'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5'
compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') {
exclude module: 'org.apache.httpcomponents:httpclient'
}
}
我只想导入以下库：
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;
所以我可以运行以下代码：
String sendProfileData = getResources().getString(R.string.URL);
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(sendProfileData);
MultipartEntity mpEntity = new MultipartEntity();
try {
mpEntity.addPart("first_name", new StringBody("Jay"));
mpEntity.addPart("last_name", new StringBody("Shmidt"));
...
}
...
这里到底出了什么问题 - 我是否真的需要删除或替换jar文件？为什么不平息这个呢？
任何建议都会有所帮助。提前谢谢！

这不是Android Studio中的问题，只有您的系统需要互联网连接
