How to Correctly Read a Text File from Within an Android Application?

How to Read a Text File in Android

When attempting to read a text file from a code path, an exception may occur. To resolve this issue, it's crucial to ensure that the correct file path is used.

In the provided code, the file path "E:testsrccomtestmani.txt" is specified. However, this path is not accessible within the Android application sandbox.

The correct approach for reading a text file in Android is to place it in one of the following locations:

  • /data/data//files/
  • /Android/data//files/

For example, you could place the file at "/data/data//files/mani.txt".

Here's an example code that demonstrates the corrected approach:

try {
    InputStream instream = openFileInput("mani.txt"); // Assuming the file is placed in the application folder
} catch (Exception e) {
    String error = e.getMessage();
}
Copy after login

Alternatively, you can use the following code to read a file from the external storage:

public static String readFromFile(Context context, String nameFile) {
    String aBuffer = "";
    try {
        File myFile = new File(pathRoot + nameFile);
        FileInputStream fIn = new FileInputStream(myFile);
        BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
        String aDataRow = "";
        while ((aDataRow = myReader.readLine()) != null) {
            aBuffer += aDataRow;
        }
        myReader.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return aBuffer;
}
Copy after login
