无法从资产读取整个文件

Question

I'm trying to read a plist file from my assets folder, but the file is read only to line 153 - not to the end. Can anyone help me and tell me why is this happening?

If i log do this Log.v("ReadFromFile("filename.plist",this); I'm getting content to 153-rd line. What am I missing, why I'm not getting the content of the whole file? Here is my code:

public String ReadFromfile(String fileName, Context context) {
        InputStream input;
        String text = null;
        try {
            input = context.getAssets().open(fileName);

            int size = input.available();
            byte[] buffer = new byte[size];
            input.read(buffer);
            input.close();

            // byte buffer into a string
            text = new String(buffer);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return text;
    }

And the content of the file I'm trying to read is this:

Answer 1

In addition to the possible issues with using Log for testing, you are making an invalid assumption about the behavior of available() . Quoting the documentation :

It is particularly important to realize that you must not use this method to size a container and assume that you can read the entirety of the stream without needing to resize the container.

The best solution is to move the file out of assets/ and into res/xml/ , then use getXml() on Resources to read it in. This will parse ~10x faster than parsing it other ways.

If you absolutely do need to have this in assets, or you need it as a full string for some reason, you need to loop, as is covered in Read/convert an InputStream to a String .

Answer 2

I put your file in assets by the name "text.xml" and i am able to read the full content in a string :-

String jsonString = null ;
    try{
    InputStream is = getAssets().open("test.xml");

    int size = is.available();

    byte[] buffer = new byte[size];

    is.read(buffer);

    is.close();

    jsonString = new String(buffer, "UTF-8");
    }
    catch(Exception e){
        e.printStackTrace();
    }
    System.out.println(jsonString);
