哪里把txt文件放在eclipse中，android？

Question

This is the code in which I need to access a txt file "USSTATES.txt".

 public int count(String filename) throws IOException {
InputStream is = new BufferedInputStream(new FileInputStream(filename));

Where should I save the file in the hard drive? I tried putting it in assets folder and the root folder of the app, but I still get the "No such file or directory" error when I run the code.

Where should I save the file in the hard drive? I tried putting it in assets folder and the root folder of the app, but I still get the "No such file or directory" error when I run the code.

So generally you have a few options based on character of file, content of file, size of file.

• Save file into sd card
• Save file into assets folder
• Save file into raw folder

Examples:

SD card:

private final String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/filename.txt";
FileInputStream is = new FileInputStream(path);

Assets folder:

InputStream is = getAssets().open("filename.txt");
BufferedInputStream bis = new BufferedInputStream(is);

Raw folder:

InputStream is = getResources().openRawResource(R.id.filename);
BufferedInputStream bis = new BufferedInputStream(is);

Suggestions:

If your file has small size, normally save it either into assets folder or raw folder. If has bigger size for example 5-10+ MB better solution is to place it into SD card.

Answer 2

You have to put your file in the assets folder

To access it you do it like that.

AssetManager am = getApplicationContext().getAssets();
InputStream is = am.open("file_name.txt");
