Android path to asset txt file

问题

I'm doing:

FileReader fin = new FileReader("file:///android_asset/myFile.txt");

in an Android project and many variations. At runtime I get a file not found exception. The file is present and correct in the assets folder, so my path must be wrong.

What is the absolute path I need here?

回答1:

AssetFileDescriptor descriptor = getAssets().openFd("myfile.txt");
FileReader reader = new FileReader(descriptor.getFileDescriptor());

Try using the above with FileDescriptors. Seems to be the most foolproof way I've found to gather asset paths.

回答2:

    InputStream is = getResources().getAssets().open("terms.txt");
    String textfile = convertStreamToString(is);

public static String convertStreamToString(InputStream is)
            throws IOException {
            Writer writer = new StringWriter();

            char[] buffer = new char[2048];
            try {
                Reader reader = new BufferedReader(new InputStreamReader(is,
                        "UTF-8"));
                int n;
                while ((n = reader.read(buffer)) != -1) {
                    writer.write(buffer, 0, n);
                }
            } finally {
                is.close();
            }
            String text = writer.toString();
            return text;
    }

Can you use something like

    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(context.getAssets().open("fileName.txt")));
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

回答4:

Its not reading it because all assets in assets folder are compressed, try changing its extension to .mp3 then read it in, that should stop it from being compressed.

回答5:

I found that if you are using an IDE like Eclipse you may need to do a clean -- or delete the API in the bin directory. It seems that the assets isn't getting updated when you do a build.

回答6:

AssetManager am = context.getAssets();
InputStream fs = am.open("myFile.txt");
