嗨，我创建了我的第一个 Hello World 应用程序并按照 developer.android 上发布的说明进行操作，但是当我连接我的索尼 xperia 并启用调试并运行我的应用程序时，我在 logcat 错误中看到“E /（4446）：不能打开文件进行阅读”我正在使用 Eclipse 的 ADT 插件
package com.example.myfirstapp;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MyMainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_my_main, menu);
return true;
}
}

任何想法请什么导致“无法打开文件”错误感谢您对完整 logcat 堆栈的支持
