Android sdk vs AndEngine vs libGDX

As the title says, soon I will begin to work on a game for android, so I decided to do a little test between Android SDK, AndEngine and libGDX. The results left me so amazed that I decided to put a video on youtube, hope you enjoy.

Saving files to External Storage in Android

Just a snippet of code for android that can help some of my friends.

String FILENAME = "myfile.txt";
boolean externalStorageMounted = false;
boolean externalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
 externalStorageMounted = true;
 externalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
 externalStorageMounted = true;
 externalStorageWriteable = false;
} else {
 externalStorageMounted = false;
 externalStorageWriteable = false;
}

if (externalStorageMounted && externalStorageWriteable) {
 File dbfile = new File(Environment.getExternalStorageDirectory(), FILENAME);
 FileOutputStream fos = new FileOutputStream(dbfile, true);
 //Do anything with fos
 try {
  if (fos != null)
   fos.close();
 } catch (IOException e) {
  e.printStackTrace();
 }
}

Ok, almost done, but not yet.Open your AndroidManifest.xml and add the following line

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

or  using graphical interface: Permissions -> Add... -> android.permission.WRITE_EXTERNAL_STORAGE

And everything ready.

Recently a friend of mine told me about an attempt to put Android 4.0 on Samsung GT540, it seemed too unrealistic but it is perfectly true, here is the link to the blog of the person who is attempting such a feat.

And to give a special touch, a video too.

If someone wants to try, do not forget to leave some feedback about this experience :)
