也许这是一个新手问题，因为我还是 java/android..sorry.. 的新手。我在 onclick(SettingActivity) 收到以下错误日志。我发现一些类似的帖子谈论了我已经从城市飞艇库导入的 jar 文件。希望有人可以帮助我度过难关。非常感谢！

Unable to resolve superclass of Lcom/app/android/SettingActivity; (2487)
Link of class 'Lcom/app/android/SettingActivity;' failed
Could not find class 'com.app.android.SettingActivity', 
  referenced from method com.app.android.HomeActivity.onOptionsItemSelected
VFY: unable to resolve const-class 594 (Lcom/app/android/SettingActivity;) 
  in Lcom/app/android/HomeActivity;

HomeActivity.java 

// Initiating Menu XML

@Override
public boolean onCreateOptionsMenu(Menu bottom_menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.bottom_menu, bottom_menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.btn_logout:
        userFunctions.logoutUser(getApplicationContext());
        Intent login = new Intent(getApplicationContext(), LoginActivity.class);
        login.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(login);
        finish();
        return true;
    case R.id.btn_setting:
        Intent i = new Intent(getApplicationContext(), SettingActivity.class);
        startActivity(i);
        finish();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

SettingActivity.java

package com.app.android;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

import com.urbanairship.Logger;
import com.urbanairship.analytics.InstrumentedActivity;
import com.urbanairship.location.UALocationManager;

public class SettingActivity extends InstrumentedActivity {

    Button launchButton, locationButton;
    IntentFilter boundServiceFilter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.setting);

更新

现在我在清理后得到这些错误..

尝试在您的项目目录中创建一个文件夹libs（与可绘制对象、资产等平行）并将所有外部 jar 放在那里..

然后右键单击您的项目->配置构建路径->添加外部jar（从libs文件夹添加它们），

并清理您的项目..应该可以正常工作..
