How to Correctly Read a Text File in an Android Application?

How to Read a Text File in Android

You wish to access text content from a file using your Android application, but encounter an exception. To resolve this, consider the following:

Correct Path to Text File

Ensure that you have placed the text file (mani.txt) in the appropriate location. In your code, you indicate the path as "E:\test\src\com\test\mani.txt". This path refers to your local computer's file system, not the Android device's file system.

Suggested Code

Replace the original code with the following, which uses Context to access the device's file system:

public static String readFromFile(Context context, String filename) {
    String data = "";
    try {
        FileInputStream inputStream = context.openFileInput(filename);
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

        String line;
        while ((line = reader.readLine()) != null) {
            data += line;
        }

        reader.close();
        return data;
    } catch (FileNotFoundException e) {
        // Handle file not found exception
    } catch (IOException e) {
        // Handle input/output exception
    }
    return data;
}

Usage

Call the readFromFile method with the context of your activity or application and the filename of the text file. The method returns the text content as a string.
