尝试检查内部存储中是否存在文件 [英] Trying to check if a file exists in internal storage

问题描述

以下代码是我如何确定内部存储中是否存在文件， MODE_PRIVATE 。

The following code is how I am trying to identify if a file exists in the internal storage, MODE_PRIVATE.

public boolean isset(String filename){
    FileInputStream fos = null;
    try {
       fos = openFileInput(filename);
       //fos = openFileInput(getFilesDir()+"/"+filename);
       if (fos != null) {
         return true;
       }else{
         return false;
       }
    } catch (FileNotFoundException e) {
        return false;
    }

    //File file=new File(mContext.getFilesDir(),filename);

    //boolean exists = fos.exists();
    }

然而，它进入异常并且不继续使用代码。它没有回报。为什么？

However, it goes into the exception and doesn't continue with the code. It doesn't do the return. Why?
