Question

Can anyone tell me why my code below does not work? I’m trying to append a string to the contents of a text/html file. I just followed the code in the android dev docs here

package com.example.GetContentThenAppend;

import java.io.FileOutputStream;
import java.io.IOException;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.Environment;

public class GetContentThenAppend extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
            String FILENAME = Environment.getExternalStorageDirectory() + "/EngagiaDroid/videos.html";
            String string = "<div style='color: blue; border: thin solid red;'>YO!</div>";

            FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_APPEND);
            fos.write(string.getBytes());
            fos.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}

I guess your problem in permissions,, have you added write to files permission in your manifest. You can do this by adding this to the manifest file

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
