Screen capture file not being saved

Question

According to this link(How to programmatically take a screenshot in Android?), I used the answer to take a capture and save it on my device's external memory.

I have all the permission cleared, and according to the log, the file is not empty at all. But I can't find the file neither on the gallery nor the file explorer.

Why is this happening? Can someone help me out with this?

On regards to Rotwang, I've figured out what the problem was.

The path of the getExternalStorageDirectory() did not seen to return a valid directory for the file to be saved.

In my case, it was about saving screenshots for the user to look on the gallery.

So, I used Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES); instead.

So, the full code for saving a screen capture is below.

 private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

    try {

        File path = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        File file = new File(path, now + ".jpg");

        path.mkdirs();

        View v1 = getWindow().getDecorView().getRootView();
        v1.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        //File imageFile = new File(mPath);

        FileOutputStream outputStream = new FileOutputStream(file);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
        outputStream.flush();
        outputStream.close();

        MediaScannerConnection.scanFile(this,
                new String[] { file.toString() }, null,
                new MediaScannerConnection.OnScanCompletedListener() {
                    public void onScanCompleted(String path, Uri uri) {
                        Log.e("ExternalStorage", "Scanned " + path + ":");
                        Log.e("ExternalStorage", "-> uri=" + uri);
                    }
                });


    } catch (Throwable e) {
        Log.e("Error", "Exception on TakeScreenshot", e);
    }
}

Thanks again Rotwang.
