java - 最初の画像のアップロード後にカメラがクラッシュする

Question

写真を撮り、その写真をサーバーにアップロードするアプリを作成しようとしています。ここまでは順調ですね。問題は、最初の写真をアップロードした後に別の写真を撮りたいときです。OutOfMemory エラーのように見えますが、私の人生では理解できません。

public class HomePage extends Activity implements OnClickListener {

    private static final int TAKE_PICTURE = 0;
    private Uri mUri;
    private Bitmap mPhoto;

    TextView welcomeText;
    String username;

    // Alert Dialog Manager
    AlertDialogManager alert = new AlertDialogManager();

    // Session Manager Class
    SessionManagement session;

    // Button Logout
    Button btnLogout;

    // Photo File
    File photoFile;
 @Override

 public void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_home);

     // Session class instance
     session = new SessionManagement(getApplicationContext());

     // Check that user is logged in
     session.checkLogin();
     // get user data from session
     HashMap<String, String> user = session.getUserDetails();
     // username
     username = user.get(SessionManagement.KEY_USERNAME);

     welcomeText = (TextView) findViewById(R.id.welcometext);

     ((Button) findViewById(R.id.snap)).setOnClickListener(this);
     ((Button) findViewById(R.id.rotate)).setOnClickListener(this);
     ((Button) findViewById(R.id.upload)).setOnClickListener(this);

     // Button logout
     ((Button) findViewById(R.id.btnLogout)).setOnClickListener(this);

     welcomeText.setText("Hello, " + username);


 }


@Override

これは、ボタンを開始した場所です。R.id.snap で写真を撮影し、R.id.upload ボタンでアップロードします。R.id.rotate を無視します。

public void onClick(View v) {

    if (v.getId()== R.id.snap) {
        Intent i = new Intent("android.media.action.IMAGE_CAPTURE");
        photoFile = new File(Environment.getExternalStorageDirectory(), username + ".jpg");

        i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
        mUri = Uri.fromFile(photoFile);
        startActivityForResult(i, TAKE_PICTURE);
    } 
    else if(v.getId() == R.id.rotate) 
    {
        if (mPhoto!=null) {
                    Matrix matrix = new Matrix();
       matrix.postRotate(90);
       mPhoto = Bitmap.createBitmap(mPhoto , 0, 0, mPhoto.getWidth(), mPhoto.getHeight(), matrix, true);
       ((ImageView)findViewById(R.id.photo_holder)).setImageBitmap(mPhoto);

           }

    }
    else if (v.getId() == R.id.upload)
    {
        try {
            welcomeText.setText("Uploading image");
            executeMultipartPost();
            //welcomeText.setText("Upload Complete");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            welcomeText.setText("Upload Failed");
            e.printStackTrace();
        }

    }
    else if (v.getId() == R.id.btnLogout)
    {
        session.logoutUser();
    }

}

@Override

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
   switch (requestCode) {
   case TAKE_PICTURE:
       if (resultCode == Activity.RESULT_OK) {
           getContentResolver().notifyChange(mUri, null);
           ContentResolver cr = getContentResolver();
           try {
               mPhoto = android.provider.MediaStore.Images.Media.getBitmap(cr, mUri);
            ((ImageView)findViewById(R.id.photo_holder)).setImageBitmap(mPhoto);
           } catch (Exception e) {
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
              }
         }
   }

}

そして、これがファイルのアップロードが行われる場所です。

@SuppressWarnings("deprecation")
public void executeMultipartPost() throws Exception {
    try {

    HttpClient httpClient = new DefaultHttpClient();
    HttpPost postRequest = new HttpPost(
            "http://www.neurobomber.com/cfc/upload_nologin.php?method=post");

    ImageView jpgView = (ImageView)findViewById(R.id.photo_holder);
    Bitmap bitmap = BitmapFactory.decodeFile(photoFile.getAbsolutePath());
    jpgView.setImageBitmap(bitmap);

    FileBody bin = new FileBody(photoFile);
    MultipartEntity reqEntity = new MultipartEntity(
            HttpMultipartMode.BROWSER_COMPATIBLE);
    //Adding the file and username to be sent to the server
    reqEntity.addPart("userfile", bin);
    reqEntity.addPart("username",new StringBody(username));
    postRequest.setEntity(reqEntity);
    HttpResponse response = httpClient.execute(postRequest);
    HttpEntity entity = response.getEntity();
    InputStream webs = entity.getContent();
    BufferedReader reader = new BufferedReader(new InputStreamReader(webs, "iso-8859-1"),8);
    String sResponse;
    StringBuilder s = new StringBuilder();

    while ((sResponse = reader.readLine()) != null) {
        s = s.append(sResponse);
    }
    welcomeText.setText(s);
} catch (Exception e) {
    // handle exception here
    //infotext.setText("Uploading image");
    Log.e(e.getClass().getName(), e.getMessage());
}
}
}

クラッシュした後のログ出力は次のとおりです。
