在示例Android应用程序中使用解析SDK库时出错

Question

在这里,我正在为第三方sdk命名parse sdk,它为Android平台提供了一些api.

我浏览了这个链接并尝试为这个解析sdk做一些示例工作.

但是在完成了该链接上提到的所有stpes之后我无法运行这个测试android应用程序.

我在logcat中遇到以下错误.

我已经在libs文件夹中导入了.jar文件,这是我在项目的根目录下创建的.

码:

package com.parse.starter;

import com.parse.Parse;
import com.parse.ParseObject;

import android.app.Activity;
import android.os.Bundle;

public class ParseStarterProjectActivity extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Parse.initialize(this, "ZVhSPsDKds8cerZ2jjDNXCpu332RHtix6Gp7YkDa", "poQXYifVzMd6haf56U5FQ13xeCxecdGippZeCMyVO");
         ParseObject testObject = new ParseObject("TestObject");

         testObject.put("foo", "bar");
         testObject.saveInBackground();
        setContentView(R.layout.main);
    }
}

Answer 1

将下载的.jar文件添加到libs文件夹中.然后在eclipse中,右键单击该.jar文件并选择"add to build path".然后再次运行您的项目.这应该解决它.
