找不到方法`com.mashape.relocation.conn.ssl.AbstractVerifier.extractCN`引用的类`javax.naming.ldap.LdapName`

Question

我有以下示例活动：

package teste.myapplication;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView text = (TextView) findViewById(R.id.mainText);
        try {
            text.setText(Unirest.get("http://google.com").asString().getBody());
        }catch (UnirestException e){
            throw new RuntimeException(e);
        }
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

我从官方指南后面的源代码编译了Unirest，最后得到了一个名为unirest-java-1.4.6-SNAPSHOT-withDependency-ShadedForAndroid.jar的.jar。

当我运行该活动时，它会立即与标题上的错误中断。下面是完整的堆栈跟踪(带有错误筛选器的logcat)：

build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "teste.myapplication"
        minSdkVersion 19
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.2'
    compile files('libs/unirest-java-1.4.6-SNAPSHOT-withDependency-ShadedForAndroid.jar')
}

我不知道会是什么。我已经试过重新编译图书馆了，但没有什么变化。

最后，我使用了改造，它工作起来很有魅力。

最后，在运行API 21的AVD中，错误消失了(我以前在AVD运行API 19上测试，我的手机也在19上)，也许更新是关键，但是如果您的应用程序目标是API 19和更低版本，而且您不能更改库，那么我就不知道了。

在您的android设备上，转到“设置”、“关于软件”、“系统更新”、“更新”。
