我正在尝试创建一个可以拍摄照片并将照片上传到我的服务器的应用程序。到目前为止，一切都很好。问题是当我想在上传第一张照片后尝试拍摄另一张照片时。它看起来像一个 OutOfMemory 错误，但对于我的生活，我无法弄清楚。
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();
}
}
}
}
这就是文件上传发生的地方。
@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());
}
}
}
如果这有帮助的话，这是我崩溃后的日志输出：
