Rotation tag mp4parser android

I'm trying to get the rotation information in the MP4 video, I'm trying to use mp4parser for this but I'm not sure how can I get it, I'm doing this,
IsoFile isoFile = null;
try {
isoFile = new IsoFile(filePath);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
List<Box> boxes = isoFile.getBoxes();
for (Box box : boxes) {
System.out.println(box);
}
and the output is this
I/System.out(23548): FileTypeBox[majorBrand=isom;minorVersion=0;compatibleBrand=isom;compatibleBrand=3gp4]
I/System.out(23548): MovieBox[]
I/System.out(23548): com.coremedia.iso.boxes.FreeBox#0
I/System.out(23548): MediaDataBox{size=7913167}
Any idea how can I get the rotation tag value?
Update 1 The working code
import java.io.File;
import java.io.FileInputStream;
import android.app.Activity;
import android.os.Bundle;
import com.coremedia.iso.IsoFile;
import com.coremedia.iso.IsoTypeReader;
import com.coremedia.iso.boxes.Box;
import com.coremedia.iso.boxes.MovieBox;
import com.coremedia.iso.boxes.UserDataBox;
import com.googlecode.mp4parser.authoring.Movie;
import com.googlecode.mp4parser.authoring.container.mp4.MovieCreator;
import com.googlecode.mp4parser.util.Matrix;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String filePath = "/storage/emulated/0/test/test.mp4";
Activity activity = (Activity) MainActivity.this;
movie = MovieCreator.build(filePath);
Matrix matrix = movie.getMatrix();
}
}

You need to get Movie object from the IsoFile or read it with MovieCreator.build(), then with movie.getMatrix() obtain what is the type of matrix: Matrix.ROTATE_O, Matrix.ROTATE_90, Matrix.ROTATE_180, Matrix.ROTATE_270
String filePath = "/path/to/movie/file.mp4"
Movie movie = MovieCreator.build(new FileInputStream(new File(filePath)).getChannel());
Matrix matrix = movie.getMatrix();

Working with Android and Jsoup parsing a table to a certain element

The problem I am having is that I am trying to parse this website but I am getting thiserror . I am new to Jsoup and not quite sure whats making the error. Is there a way to stop parsing on certain element like if i want it to stop on first instance of Bobby? (row : Cindy : Mike : Bobby). Thanks in advance!
import android.app.Activity;

import org.jsoup.select.Elements;
public class tableScreen extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table);
takeTable();
}
public static int SDK_INT = android.os.Build.VERSION.SDK_INT;
public void takeTable()
{
Document doc = null;
if (SDK_INT >= 10)
{
ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);
}
try{
doc = Jsoup.connect("http://www.htmlgoodies.com/tutorials/tables/article.php/3479851").get();
System.out.println("1");
Element containingDiv = doc.select(".body").first();
System.out.println("2");
Elements table = containingDiv.select("table");
System.out.println("3");
Elements rows = table.select("tr");
System.out.println("4");
for (Element row : rows)
{
System.out.println("row: "+row.child(0).text()+" : "+row.child(1).text()+" : "+ row.child(2).text());
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
}

OK guys I manage to fix it ,
doc = Jsoup.connect("http://www.htmlgoodies.com/tutorials/tables/article.php/3479851").get();
Element containingDiv = doc.select("table").first();
Elements table = containingDiv.select("tbody");
Elements rows = table.select("tr");

symbol variable R.raw not find in android

toast mesage not shown on screen when network or server not available

I need to show toast message when the server is not responding
when I press the login button, some parameters are passed to AgAppMenu screen which use url connection to server and get xml response in AgAppHelperMethods screen. The
probelm is when the server is busy or the network is not avaibale, I can't show toast message on catch block although it shows the log message.

AgAppHelperMethods isn't really an Activity. You've derived this class from Activity, but then you've created Singleton management methods (getInstance()) and you are instantiating it yourself. This is bad. Don't do this.
Normally Android controls the instantiation of activities. You don't ever create one yourself (with new).
It looks to me like AgAppHelperMethods just needs to be a regular Java class. It doesn't need to inherit from anything. Remove also the lifecycle methods like onCreate().
Now you will have a problem with the toast, because you need a context for that and AgAppHelperMethods isn't a Context. To solve that you can add Context as a parameter to AgAppXMLParser() like this:
public String[][] AgAppXMLParser(Context context, String parUrl) {
...
// Now you can use "context" to create your toast.
}
When you call AgAppXMLParser() from AgAppMenu just pass "this" as the context parameter.
