Upload file to server using android

I am using the code below to upload files on server. But whenever I run this code my application closes unexpectedly.

And I am calling this method through:
void openDialogBox()
{

intent.setType("file/*");
startActivityForResult(intent, PICK_CONTACT_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode,

// A contact was picked. Here we will just display it
// to the user.
Uri uri = data.getData();
File file = new File(uri.toString());
if(uri.toString().startsWith("file:/"))
file = new File(uri.toString().substring(6));
msgTxt.setText(file.getName());
Toast.makeText(this, uri.toString(), Toast.LENGTH_SHORT).show();
try
{
UploadToServer upToServer = new UploadToServer();
upToServer.uploadToServer(file,msgTxt);
}catch(Exception e)
{
msgTxt.setText(e.toString());
e.printStackTrace();
}
}
}
}
I don't know how but it uploaded two image files before closing down.
Any help is appreciated.

"Unable to resume activity" after saving cropped image - Android

I want to load the image in ImageView after cropping the image and save it. But when it's resumes it gets crashed, but image is saving on selected location. I think the problem is in selectedImageUri. But I couldn't figure it out how to solve. Please someone help. Thanks in advance.

Edited:
I changed OnActivityResult() like this:
if(data!=null) {
Bitmap thePic = (Bitmap) data.getExtras().get("data");
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
String filename = preferences.getString("file_name", ""); // value to retrieve
String path = Environment.getExternalStorageDirectory()+"/PetSitter/Pet Images/" + filename;
img.setImageURI(Uri.parse(path.toString()));
} else {
// In createNewFile, make sure you already saved the filename (prefix+System.currentTimeMillis()+".jpg"), for example, to sharedpreferences then get the filename and apply in path
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
String filename = preferences.getString("file_name", ""); // value to retrieve
String path = Environment.getExternalStorageDirectory()+"/PetSitter/Pet Images/" + filename;
BitmapFactory.Options bfo = new BitmapFactory.Options();
bfo.inSampleSize = 1;
Bitmap bmp = BitmapFactory.decodeFile(path, bfo);
img.setImageBitmap(bmp);
}
It's seems to be working with image preview and everything. But what do thing? Is it a good practice to do? and how will be the memory usage by using like this?

In OnActivityResult():
if(data!=null) {
Bitmap thePic = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(thePic);
} else {
// In createNewFile, make sure you already saved the filename (prefix+System.currentTimeMillis()+".jpg"), for example, to sharedpreferences then get the filename and apply in path
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
String filename = preferences.getString("file_name", ""); // value to retrieve
String path = Environment.getExternalStorageDirectory()+"/test1/" + filename;

if(newDirectory.mkdir()){
Log.d(this.getClass().getName(), newDirectory.getAbsolutePath()+" directory created");
}
}
// modifications applied here
long mDate = System.currentTimeMillis();
File file = new File(newDirectory,(prefix+mDate+".jpg"));
String filename = prefix+mDate+".jpg";
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getActivity().getBaseContext());
SharedPreferences.Editor editor = preferences.edit();
editor.putString("file_name", filename); // value to store
editor.commit();
if(file.exists()){
//this wont be executed
file.delete();
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
return file;
}

Uri selectedImageURI = data.getData();
imageFile = new File(getRealPathFromURI(selectedImageURI));
And
private String getRealPathFromURI(Uri contentURI) {
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
return contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
}

Try this in onActivityResult
Bitmap photo = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(photo);

I changed OnActivityResult() like this:
if(data!=null) {
Bitmap thePic = (Bitmap) data.getExtras().get("data");

I meet this problem too, please use myRecorder=null, I think that because myRecorder.release() has bug,
you can do that:
myRecorder.stop();
myRecorder.release();
myRecorder = null;
and other place append judgement
if(myRecorder != null){ ... }

Try adding this:
mediaRecorder.stop();
mediaRecorder.reset(); //instead of release() and =null
And then in
public void onStop() {
mediaRecorder.release();
mediaRecorder = null;

I have this...
if (recorder != null) {
recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
}
... and works fine!

Try calling super first in your onCreate :
public void onCreate(Bundle icicle) {
super.onCreate(icicle);

Tesseract RECOGNITION fix?

I have been able to export my code into an application and use the Tess-Two file from this tutorial
to integrate the tesseract into it. But now I'm facing problems; when the picture is sent to the tesseract it just returns the same random characters each time: 'f' wig, W fin. A. " 5' ' ,{ >>zv' ' ~" > ';>'. What seems to be the problem?

You need to process the images before OCR, at least convert the image to black&white (gray scale) can enhance the result :
bitmap = toGrayscale(bitmap);
bitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true);
you can user OpenCV or any Image Processing Library, for for simple task like grayscale its enopugh to use
import android.graphics.*;
public static Bitmap toGrayscale(Bitmap bmpOriginal)
