我正在尝试创建一个可以拍照并将照片上传到我的服务器的应用。到现在为止还挺好。问题是我想在上传第一张照片后尝试拍另一张照片。它看起来像是OutOfMemory错误，但对于我的生活，我无法理解它。
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
这是我启动按钮的地方。 R.id.snap是拍摄照片的地方，然后我使用按钮R.id.upload上传。忽略R.id.rotate。
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();
}
}
}
}
这就是文件上传的地方。
@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());
}
}
}
这是崩溃之后我的日志输出，如果这有帮助的话：
