我想将 sdcard 中 AutoistDiary 文件夹中存储的图像显示到图库中，该活动在我编写了该代码的模拟器中开始，但是当我在我的设备上执行相同的 apk 时，它会强制关闭，
这是我的代码，它在实际设备中通过强制关闭，在这种情况下该怎么办？
//get the gallery view---------------------------------------------------------------------
Gallery g = (Gallery) findViewById(R.id.gallery);
g.setAdapter(new ImageAdapter(this, SDCard()));
g.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
{
Log.i("position", Integer.toString(position));
}
});
}
private List<String> SDCard()
{
Log.i("inside", "SDCard() method");
List<String> tFileList = new ArrayList<String>();
File dir = Environment.getExternalStorageDirectory();
// File yourFile = new File(dir, "path/to/the/file/inside/the/sdcard.ext");
//It have to be matched with the directory in SDCard
File f = new File( dir, "/AutoistDiary/");
//File f = new File( "/sdcard/");
File[] files=f.listFiles();
for(int i=0; i<files.length; i++)
{
File file = files[i];
/*It's assumed that all file in the path
are in supported type*/
tFileList.add(file.getPath());
msg="getting autioistdiary file path" + i+tFileList;
showToastMessage(msg);
}
return tFileList;
}
