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.
Code:

And code for php is:

if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {

} else{
echo "fail";
}
?>
And I am calling this method through:
void openDialogBox()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, PICK_CONTACT_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == PICK_CONTACT_REQUEST) {
if (resultCode == RESULT_OK) {
// 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.

How to solve OutOfMemory Exception when uploading image?

I am able to upload to the server the image of file size less than probably 1Mb and will get the OutOfMemory error if i upload more than 1Mb. I have used the BitmapFactory to decode the file but still unable to upload large image files.

-------EDIT--------
After adding the below code, I do not get anymore OutOfMemory exception and it says "upload successful", but nothing was uploaded.
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
Bitmap bm = BitmapFactory.decodeFile(strPath,options);
imageView.setImageBitmap(bm);

1. for out of memory error add below line to your Manifest file inside <application> tag-
`<application
...
android:largeHeap="true"
</application>`
2. Your way of programming is totally wrong for layout initialization like
inputName = (EditText) findViewById(R.id.inputName);
inputLocation = (EditText) findViewById(R.id.inputLocation);
inputDesc = (EditText) findViewById(R.id.inputDesc);
this should be in onCreate(Bundle arg0) for best practice
and one more for image uploading like process you have to use AsyncTask for ex : How can I use an Async Task to upload File and Resize your bitmap file to avoid such errors
3.for large image problem you have to change setting of php server.
by default http request allow to upload data upto 2 mb on a php server.if you want to increase upload limit then go to your php config file and set upload limit to what ever you want.

Use AsyncTask for uploading the image.. Because you cannot do upload and download task on the UI thread.

You need to resize bitmap to solve this problem but before that just try one thing, add largeHeap = true tag in Android manifest's application tag.

Android Error while Uploading an image to server

I'am using the following code from the tutorial :
http://geekonjava.blogspot.in/2014/03/upload-image-on-server-in-android-using.html
Whenever I run the code , it shows the following error on log cat and force closes the app on click of Upload Button. Can anyone help me on this ?

Check your logs : you have NullPonterException in line :
File sourceFile = new File(sourceFileUri); // your sourceFileUri = null here,
since you call uploadFile() with null agrument.

According to the logcat, the code is crashing at line 43 with a Null Pointer Exception, and I can't tell which line 43 is. However:
Have you checked that Environment.getExternalStorageDirectory().getAbsolutePath() is returning non null? It maybe that there is no external storage directory, or you don't have permission to know about it.
It is also worth reading the developer pages, http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory(), which note that you shouldn't write to that directory, which you seem to be doing.

I solved this problem by myself. There was error in static variable who was changing his value due to logical error in code.

what is LifeLogSecurityUtility?
It is possible this line:
[LifeLogSecurityUtility]lifelogdb permission error
is telling you that you are missing a permission tag in your manifest. Though I am not familiar with this LifeLogSecurityUtility so I wouldn't know which permission that thing is wanting you to have.

If you have not done so already add the WRITE_EXTERNAL_STORAGE permission to your AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
