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);
    }
}

我在official guide之后从源代码编译了Unirest，最后得到了一个名为.jar的{{1}}。

当我运行活动时，它会立即中断标题上的错误。这是完整的堆栈跟踪（带有错误过滤器的logcat）：

unirest-java-1.4.6-SNAPSHOT-withDependency-ShadedForAndroid.jar

我不知道会是什么。我已经尝试重新编译库，但我没有改变。

Answer 1

在Android设备上，转到＆＃34;设置＆＃34;，＆＃34;关于软件＆＃34;，＆＃34;系统更新＆＃34;，＆＃34;更新＆＃34;

Answer 2

我最终使用的Retrofit就像一个魅力。

最后，在运行API 21的AVD中我的错误消失了（我之前在运行API 19的AVD上进行了测试，我的手机也在19号），可能更新是关键，但如果你的应用程序目标是API 19及更低版本，你无法更改库，那我就不知道了。

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