请求解释一个异常
源程序：
public class OtherActivity extends LauncherActivity
{
//定义两个Activity的名称
String[] names = {"设置程序参数" , "查看星际兵种"};
//定义两个Activity对应的实现类
Class<?>[] clazzs = {PreferenceActivityTest.class
, ExpandableListActivityTest.class};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1 , names);
// 设置该窗口显示的列表所需的Adapter
setListAdapter(adapter);
}
//根据列表项来返回指定Activity对应的Intent
@Override public Intent intentForPosition(int position)
{
return new Intent(OtherActivity.this , clazzs[position]);
}
}

备注：单独启动PreferenceActivityTest.class和 ExpandableListActivityTest.class没有问题
[解决办法]
看看哪儿是不是出现空指针了
[解决办法]
Unable to open stack trace file '/data/anr/traces.txt': Permission denied

权限？
------解决方案--------------------

引用:

引用:Unable to open stack trace file '/data/anr/traces.txt': Permission denied

权限？

需要什么权限？<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://s……

=。=
你自己的程序 我怎么知道需要什么权限。。。
[解决办法]
Unable to open stack trace file '/data/anr/traces.txt': Permission 多见于这个Activity你没有在AndroidManifest.xml中注册


你的这个程序好像和这里的一样：
