Java 更新后无法连接到Parse.com'；Android支持库'；v22

我正在使用Android Studio，在将“Android Support Library”更新到ver后，我无法连接到Parse.com。22 以前有效的项目现在无效。 经过数小时的搜索和测试，我决定只为此打开一个清晰的项目，但问题仍然存在

main活动类

public class MainActivity extends Activity {
   List<ParseObject> data;
   List<String> nameList;
   String[] name;

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

    String appId = " ********* ";
    String clientId = " ********* ";
    Parse.initialize(getApplicationContext(), appId, clientId);

    ParseQuery<ParseObject> query = ParseQuery.getQuery("test");
    try {
        data = query.find();

    }catch (ParseException e){
        Log.i("myParseExceptionLog", "Can't connect to test table at parse");
    }

    nameList = new ArrayList<String>();
    for (int i=0 ; i < data.size(); i++){
        nameList.add(data.get(i).getString("name"));
    }
    name = nameList.toArray(new String[nameList.size()]);

    TextView myTV = (TextView)findViewById(R.id.test);
    myTV.setText(name[0]);
}
}

我知道我需要在build.gradle中删除我的JAR，但请看注释。 无论如何，它会出现在项目结构中，我可以从类中的parse导入libs。 当我试图删除build.gradle中的依赖项并同步Manifat时

黑屏2分钟后，应用程序记得崩溃并给我带来NullPointerExpiton（因为“数据”为null）

LogCat错误

我在干什么？
我错过了什么？
新的“Android支持库”版本有什么问题吗

编辑：

我刚刚做了另一个测试，我从他们的网站下载了一个CompletExampleOD解析，包括所有的设置和最后的解析版本。我重新安装了Android Support Library，但仍然无法正常工作

是的，看起来第39行有空值，您可以将行号添加到该行中，以便我们可以看到该空值被抛出的位置吗？

好，如果

for（int I=0；I

产生空点异常这肯定是因为

数据

为空，所以您必须检查

数据

是否为空。

您能在MainActivity中显示第39行吗？根据parse docs，最好将

应用程序划分为子类，并在
onCreate
中对其进行初始化。我知道我在所有应用程序中都这样做了。现在的例子是这样的。第39行：for（int i=0；iat android.app.ActivityThread.access$800(ActivityThread.java:151)
