My code:

private Bitmap mBitmap;
private Canvas mCanvas;
private Bitmap tmpBitmap;
private Canvas tmpCanvas;
private DrawHandler mDrawHandler;
private Canvas tCanvas;
private String mImagePath = Environment.getExternalStorageDirectory() + "/anppp";
private File file;

public void saveapp() {

    Calendar currentDate = Calendar.getInstance();
    SimpleDateFormat formatter= new SimpleDateFormat("yyyyMMMddHmmss");
    String dateNow = formatter.format(currentDate.getTime());
    file = new File(mImagePath + "/" + dateNow +".png");
    FileOutputStream fos;
    try {
        file.createNewFile();
        fos = new FileOutputStream(file);
        tmpBitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
        fos.close();
        } catch (FileNotFoundException e) {
        Log.e("Panel", "FileNotFoundException", e);
    }
    catch (IOException e) {
        Log.e("Panel", "IOEception", e);
    }
}

That’s it .. I do not know what could be wrong ;(

Answer 1

I think you are not having the folder with name anppp in your sdcard.
So i suggest you to first create it using

File dirPath = new File(Environment.getExternalStorageDirectory().toString() + "/anppp");
dirPath.mkdirs();

and now perform the tasks you are doing.
Hope this helps you
