Could not find class `javax.naming.ldap.LdapName` referenced from method `com.mashape.relocation.conn.ssl.AbstractVerifier.extractCN`

Question

I have the following example activity:

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);
    }
}

I compiled Unirest from the source following the official guide and ended up with a .jar named unirest-java-1.4.6-SNAPSHOT-withDependency-ShadedForAndroid.jar.

When I run the activity, it immediately breaks with the error on the title. Here's the full stacktrace (logcat with Error filter):

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 {
            minifyEnabled false
            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')
}

I don't know what could be. I tried recompiling the library already, but I had no change.

Answer 1

I ended up using Retrofit which worked like a charm.

In the end, though, the error went away in an AVD running API 21 (I was previously testing on an AVD running API 19, and my phone was also on 19), maybe updating is key, but if your application targets API 19 and lower, and you can't change the library, then I wouldn't know.
