java Android Apache POI

Question

您好，我正在使用Apache POI从pptx（如quickoffice 安卓）获取幻灯片，但我得到的错误代码是：

XMLSlideShow ppt;
XSLFSlide blankSlide;

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

    try {
        ppt = new XMLSlideShow(new FileInputStream(Environment.getExternalStorageDirectory()+"/ppt/test.pptx"));

        //append a new slide to the end
        blankSlide = ppt.createSlide();
    } catch (IOException e) {
        e.printStackTrace();
    }

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

编译之后，我遇到了一个错误，应用程序停止了 错误：
