Question

我在我的Android应用程序中使用HTTP核心和客户端jar。我在SDK 23上运行。我没有得到任何编译时错误。应用程序运行，直到调用getRally方法，该方法使用外部依赖项。

我的mainactivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

import com.rallydev.rest.RallyRestApi;
import com.rallydev.rest.request.QueryRequest;
import com.rallydev.rest.response.QueryResponse;

public class MainActivity extends AppCompatActivity
{
    String host = "https://rally1.rallydev.com";


    String applicationName = "Android-Rally";
    RallyRestApi restApi;
    Button buttonlogin;
    EditText etemail,etpass;
    QueryRequest qtestset;
    QueryResponse response;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        etemail=(EditText) findViewById(R.id.etemail);
        etpass=(EditText) findViewById(R.id.etpassword);
        buttonlogin=(Button) findViewById(R.id.btnlogin);
        buttonlogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v)
            {
                if(etemail.equals("") && etpass.equals(""))
                {
                    Toast.makeText(getApplicationContext(),"Enter your Rally Credentials",Toast.LENGTH_LONG).show();
                }
                else
                {
                    try
                    {
                        getRally();
                    }
                    catch (URISyntaxException e)
                    {
                        e.printStackTrace();
                    }
                    qtestset = new QueryRequest("Defects");
                    qtestset.setLimit(1);
                    try
                    {
                        response = restApi.query(qtestset);
                        if(!response.wasSuccessful())
                        {
                            Toast.makeText(getApplicationContext(),"Login Un-Successful",Toast.LENGTH_LONG).show();


                        }
                        else{
                            Toast.makeText(getApplicationContext(),"Login Successful",Toast.LENGTH_LONG).show();
                        }
                    }
                    catch (IOException e)
                    {
                        e.printStackTrace();
                    }



                }


            }
        });

    }

    public RallyRestApi getRally() throws URISyntaxException {
        String password = etemail.getText().toString();
        String email=etpass.getText().toString();
        restApi = new RallyRestApi(new URI(host), email,password);
        restApi.setApplicationName(applicationName);
        return restApi;
    }
}

我的应用Gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "22.0.1"

    packagingOptions
            {

                exclude 'META-INF/dependencies.txt'
            }


    defaultConfig {
        applicationId "com.example.apetkar.rally_rest_android"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies
        {
            compile fileTree(dir: 'libs', include: ['*.jar'])
            testCompile 'junit:junit:4.12'
            compile ('com.android.support:appcompat-v7:23.2.0')
            compile files('libs/gson-2.2.4.jar')
            compile files('libs/commons-logging-1.1.1.jar')
            compile files('libs/httpcore-4.2.4.jar')
            compile files('libs/httpclient-4.2.5.jar')
            compile files('libs/rally-rest-api-2.2.1.jar')

        }

我确实调查了这个问题。问题是android的默认org.apache.http.client.utils.URIUtils在运行时被调用，它不包含方法提取主机。方法extracthost在HttpClient.jar中..所以我怎么能强制app调用Jar中的类而不是默认的androids类？

您正在使用旧的Apache HTTP客户端......而且还没有使用Android

compile group: 'org.apache.httpcomponents', name: 'httpclient-android', version: '4.3.5.1'

Simliarly，你真的不需要JAR文件，我不这么认为。

compile group: 'com.rallydev.rest', name: 'rally-rest-api', version: '2.2.1'
compile group: 'com.google.code.gson', name: 'gson', version: '2.8.0'
compile group: 'commons-logging', name: 'commons-logging', version: '1.2'

如何强制应用程序调用Jar中的类而不是默认的androids类

我不确定Rally API库是否需要Apache HTTP，但我建议使用不同的HTTP库，因为在Android 23中删除了Apache HTTP，这是您编译的，所以代码不应该调用默认类。

我的应用程序在运行时没有使用添加的依赖项
