Android File not created on SD card

I'm trying to create a file on the SD on my device. This worked a week ago, but now it isn't, and I don't understand why.

The Logcat prints:

java.io.FileNotFoundException ...pathtofile... (no such file or directory)

So, the file is not being created. I have the correct permissions on the android manifest:

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

I create the file this way:

if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
           base = Environment.getExternalStorageDirectory().getAbsolutePath();
       }
   String fname = File.separator +"VID_"+ timeStamp + ".3gp";
       mediaFile = new File(base+fname);

Then I check if it exists:

   if(mediaFile.exists()){
           Log.v("mediaFile","ex");
       }else{
           Log.v("mediaFile","no ex");

       }

And the log says that IT DOESN'T EXIST. I also have tried with file.createNewFile() and it doesn't work.

So, a week ago it was working, now it doesn't work, it could be a problem with the SD card ???? Could it be some type of BUG!!!????

Thanks

EDIT: More Code

The function where the file is created is :

private static File getOutputMediaFile()

Called from:

private static Uri getOutputMediaFileUri(){
         return Uri.fromFile(getOutputMediaFile());
   }

And setted to mediarecorder output as:

vMediaRecorder.setOutputFile(getOutputMediaFileUri().toString());

So, when I do mediarecorder.prepare():

try {
            vMediaRecorder.prepare();

        } catch (IllegalStateException e) {
            Log.v("RELEASE VIDREC1",e.toString());
            releaseMediaRecorder();
            return false;
        } **catch (IOException e) {
            Log.v("RELEASE VIDREC2",e.toString());
            releaseMediaRecorder();
            return false;**
        }

The bold catch is the one that runs, and prints:

java.io.FileNotFoundException ...pathtofile... (no such file or directory)

Thanks for your help, I've solved the problem using old code. It is strange because the "file saving" part has no modification. Thanks for all guys, kinda.

You merely create the object mediaFile, not the actual file. Use this:

if(!f.exists()){
  f.createNewFile();
}

I tried this, for me it works.

final String filename = "file.3gp";
final String path = Environment.getExternalStorageDirectory() + "/" + filename;
File outputfile = new File(path);
if (!outputfile.exists()) {
    try {
        outputfile.createNewFile();
    } 
    catch (IOException e) {
        e.printStackTrace();
    }
}
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(outputfile.toString());
try {
    recorder.prepare();
    recorder.start();
    /*recorder.stop();
    recorder.reset();
    recorder.release();*/
} 
catch (IllegalStateException e) {
    e.printStackTrace();
} 
catch (IOException e) {
    e.printStackTrace();
}

Try and see whether or not it works. If not, can you add the full code of getOutputMediaFile()?

My answer here:

First open the path, then add the file:

String dir = Environment.getExternalStorageDirectory(); // getAbsolutePath is not requried
File path = new File(dir);
File root = new File(path,  "VID_"+ timeStamp + ".3gp";);

just try this 

String fname = "VID_"+ timeStamp + ".3gp";

if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
   mediaFile = new File(android.os.Environment.getExternalStorageDirectory(),fname);
    if(!mediaFile.exists())
    {
         mediaFile.createNewFile();
    }
}

if(mediaFile.exists()){
       Log.v("mediaFile","ex");
   }else{
       Log.v("mediaFile","no ex");

   }
