Java.lang.IllegalStateException: No se puede realizar esta acción después de onSaveInstanceState: – Error en Fragment

Hola, he utilizado el fragmento A y segundo fragmento utilizado b. Una llamada a b y en el método utilizado asynctask pero he utilizado esta primera vez que está perfectamente trabajado, pero la segunda vez, a continuación, bloqueo de la aplicación y mi error de inicio de sesión a continuación ::: He trabajado Samsung comprimido perfecto trabajado, pero Samsung núcleo móvil en el accidente de la aplicación.

Mi clase se utiliza en:

 public class TakeCameraFragment extends Fragment { Camera mCamera = null; private CameraPreview mCameraPreview; protected static final int MEDIA_TYPE_IMAGE = 0; static String FilePAth = ""; Button takePicture; static String base64string = ""; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { final View rootView = inflater.inflate(R.layout.camerafragment, container, false); mCamera = getCameraInstance(); Log.v("log_tag", "mCamera :: " + mCamera); mCameraPreview = new CameraPreview(getActivity(), mCamera); FrameLayout preview = (FrameLayout) rootView .findViewById(R.id.camera_preview_fragment); preview.addView(mCameraPreview); takePicture = (Button) rootView .findViewById(R.id.btnTakePicturefragment); takePicture.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub mCamera.takePicture(null, null, mPictureframent); } }); return rootView; } public boolean checkCameraHardware(Context context) { if (context.getPackageManager().hasSystemFeature( PackageManager.FEATURE_CAMERA)) { // this device has a camera return true; } else { // no camera on this device return false; } } @Override public void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); releaseCamera(); } private void releaseCamera() { if (mCamera != null) { mCamera.release(); // release the camera for other applications mCamera = null; } } private Camera getCameraInstance() { try { Log.v("log_tag", "camera try:::" + mCamera); mCamera = Camera.open(); } catch (Exception e) { // cannot get camera or does not exist Log.v("log_tag", "camera catch:::" + mCamera); releaseCamera(); } return mCamera; } private static File getOutputMediaFile() { File mediaStorageDir = new File( Environment .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "MyCameraAppFragment"); if (!mediaStorageDir.exists()) { if (!mediaStorageDir.mkdirs()) { Log.d("MyCameraApp", "failed to create directory"); return null; } } // Create a media file name String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss") .format(new Date()); FilePAth = mediaStorageDir.getPath() + File.separator + "IMG_fragment_" + timeStamp + ".jpg"; Log.v("log", " FilePAth " + FilePAth); File mediaFile; mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_fragment_" + timeStamp + ".jpg"); return mediaFile; } PictureCallback mPictureframent = new PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { File pictureFile = getOutputMediaFile(); if (pictureFile == null) { return; } try { FileOutputStream fos = new FileOutputStream(pictureFile); fos.write(data); fos.close(); FragmentManager fm = getFragmentManager(); FragmentTransaction fragmentTransaction = fm.beginTransaction(); SetPictureImageFragment fm2 = new SetPictureImageFragment(); fragmentTransaction.replace(R.id.relative_camerafragment_id, fm2, "HELLO"); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit(); Bundle bundle = new Bundle(); bundle.putByteArray("position", data); fm2.setArguments(bundle); mCamera.startPreview(); } catch (FileNotFoundException e) { } catch (IOException e) { } } }; }

Segundo Fragmento utilizado:

 public class SetPictureImageFragment extends Fragment { ImageView img; Bundle bundle; byte[] path; byte[] byteArrayimage; Button conform; float x; Bitmap b; public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); View view = inflater.inflate(R.layout.capturepicturefragment, null); Log.v("log_tag","SetPictureImageFragment"); bundle = this.getArguments(); path = bundle.getByteArray("position"); Log.v("log_tag","SetPictureImageFragment ::: Path :: "+path); img = (ImageView) view.findViewById(R.id.camera_preview_fragment_imageview); conform=(Button)view.findViewById(R.id.conform); BitmapFactory.Options options = new BitmapFactory.Options(); options.inPurgeable = true; // inPurgeable is used to free up // memory while required Bitmap b = BitmapFactory.decodeByteArray(path, 0,path.length,options); int width = b.getWidth(); int height = b.getHeight(); int newWidth = 500; int newHeight = 500; float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; Matrix matrix = new Matrix(); matrix.postScale(scaleWidth, scaleHeight); int rotation = getActivity().getWindowManager().getDefaultDisplay().getRotation(); int finalDegree = 0; if(rotation == 0) { finalDegree = 90; } if(rotation == 1) { finalDegree = 270; } if(rotation == 2) { finalDegree = 180; } if(rotation == 3) { finalDegree = 90; } matrix.postRotate(finalDegree); Bitmap resizedBitmap = Bitmap.createBitmap(b, 0, 0,width, height, matrix, true); ByteArrayOutputStream stream = new ByteArrayOutputStream(); resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); byteArrayimage = stream.toByteArray(); img.setScaleType(ScaleType.CENTER); img.setImageBitmap(resizedBitmap); conform.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub FragmentManager fm = getChildFragmentManager(); FragmentTransaction fragmentTransaction = fm.beginTransaction(); SendImageServerFragment fm2 = new SendImageServerFragment(); // CreateStoreFragment fm2 = new CreateStoreFragment(); fragmentTransaction.replace(R.id.relative_cameraimageview_fragment, fm2, "HELLO"); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit(); Bundle bundle = new Bundle(); bundle.putByteArray("position", byteArrayimage); fm2.setArguments(bundle); } }); return view; } }

Tercer Fragmento utilizado :::

Se conoce como pérdida de estado . Has cometido una FragmentTransaction desde AsyncTask. Esto está prohibido por el propio marco.

Si está de acuerdo con la posibilidad de pérdida de estado y comportamiento inesperado por el usuario, podría utilizar

FragmentTransaction#commitAllowingStateLoss()

en lugar de

FragmentTransaction#commit()

De todos modos, considere leer el enlace que proporcioné, es una situación muy común.

Edit: También, hay una solución de su problema. Pero supongo, las consecuencias de esto llevan a una posible pérdida del estado, también. Sin embargo:

Declare un Handler en su Fragment :

 private Handler handler = new Handler();

Entonces, en su onPostExecute(..) haga esto:

 @Override protected void onPostExecute(String result) { progress.dismiss(); Toast.makeText(getActivity().getApplicationContext(), result, Toast.LENGTH_LONG).show(); handler.post(new Runnable() { @Override public void run() { hideKeybord(edt_txt); FragmentManager fm = getActivity().getSupportFragmentManager(); FragmentTransaction fragmentTransaction = fm.beginTransaction(); StoreProfileGridFragment fm2 = new StoreProfileGridFragment(); fragmentTransaction.replace(R.id.relative_sendimage_send, fm2, "HELLO"); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit(); } }); return; }
