context.getAssets().list("")方法的问题

package com.example.tttttttt;import java.io.IOException;import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;public class MainActivity extends Activity { @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for (int i = 0; i < getsearch(this).length; i++) {
System.out.println("////////////" + getsearch(this)[i]);
}
} public String[] getsearch(Context context) { String[] s = null;
try {
s = context.getAssets().list("");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} return s; }}
我想得到assets下的所有文件，但是会出现以下情况。05-15 03:13:14.750: W/dalvikvm(938): ReferenceTable overflow (max=512)
