Can Android Apps Access and Read External Text Files?

In Android app development, you may encounter a need to retrieve data from external text files. However, there are limitations to consider when accessing files outside the app's sandboxed environment. To successfully read text files, it's crucial to place them in the appropriate location and utilize the correct code.

Where to Find Your Text File

The code snippet you provided attempts to read the "mani.txt" file from a path that is specific to your computer's local file system (e.g., "E:testsrccomtestmani.txt"). This path is not accessible to an Android application.

Proper File Placement

To access external text files in Android, you should place them within the appropriate directories on the device's storage. One common location is the "External Storage" directory, accessible through Environment.getExternalStorageDirectory().

Within this directory, you can create a folder for your application-specific files or place the text file directly in the root directory. Ensure that the file is named correctly to match the reference in your code.

Suggested Code

Here's a modified code block that demonstrates how to read a text file from external storage:

String path = Environment.getExternalStorageDirectory() + "/path/to/your_file.txt";

try {
    File myFile = new File(path);
    FileInputStream fIn = new FileInputStream(myFile);
    BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
    String line;

    while ((line = myReader.readLine()) != null) {
        // Process the line of text
    }
    myReader.close();
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
