i am getting red line error message on 'context' and 'raw' in this line MediaPlayer.create(context,R.raw.music); while creating a simple media player app (music is in /res/raw folder). Pls help.. Here's the full code..
package com.example.mymedia;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.music);
mediaPlayer.start(); // no need to call prepare(); create() does that for you
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

This error can be resolved simply by 1. Creating a new 'raw' folder of 'raw' type under the 'res' folder i.e. The Android Repository.(Just right click over res>>new>>raw) 2. Further a file is needed under the folder in order to resolve the error completely. (TheRedLine goes after inserting the file) This file can be .mp3 (or according to your program)

Try this..
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaPlayer mediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.music);
mediaPlayer.start(); // no need to call prepare(); create() does that for you
}
And i hope you know means of raw..
A raw folder holds files of any type. You need a raw
folder under your resources folder (res
). In your example, jam
is expected as a resource in the raw
folder, and will likely be a type of music file as you're using MediaPlayer
to try and read it.
You've this error raw cannot be resolved
because raw folder doesn't exist, and so the variable raw
in class R
is not being auto-generated.
Fix the problem by creating the raw
folder.
If you already have created res/raw
try cleaning the project. Sometimes Eclipse gets confused. If that does work, make a small change to a source file, and save it so the auto-build process kicks off. Sometimes cleaning manually hasn't fixed the problem for me, its a known bug for Eclipse.
