How to save ImageView from API to internal storage?

I'm trying to save the image from API and is always going to catch.
public void saveSkin() {
ivSkinSaver.buildDrawingCache();
Bitmap bm = ivSkinSaver.getDrawingCache();
OutputStream Out = null;
Uri outputFileUri;
try {
File mediaFile;
File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
+ "/Android/data/"
+ getApplicationContext().getPackageName()
+ "/Files");
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
String mImageName = "MI_" + timeStamp + ".jpg";
mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);
Out = new FileOutputStream(mediaFile);
Toast.makeText(getBaseContext(),"file saved",Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(this, "Error occured. Please try again later.",
Toast.LENGTH_SHORT).show();
}
try {
bm.compress(Bitmap.CompressFormat.PNG, 100, Out);
Out.flush();
Out.close();
} catch (Exception e) {
}
}

takePicture() landscape mode rotation android

I am taking an image from camera using:
mCamera.takePicture(null, null,
new PhotoHandler(getApplicationContext()));
But the image I am taking is landscape and I want it portrait, I tried converting the file into bitmap, rotate it and then save it again, here is my onPictureTaken() function and rotate() function inside PhotoHandler.class:
#Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFileDir = getDir();
if (!pictureFileDir.exists() && !pictureFileDir.mkdirs()) {
Log.d("Error", "Can't create directory to save image.");
Toast.makeText(context, "Can't create directory to save image.",
Toast.LENGTH_LONG).show();
return;
}
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyymmddhhmmss");
String date = dateFormat.format(new Date());
String photoFile = "Picture_" + date + ".jpg";
String filename = pictureFileDir.getPath() + File.separator + photoFile;
pictureFile = new File(filename);
st1 = pictureFile.getAbsolutePath();
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
fos.close();
Toast.makeText(context, "New Image saved:" + photoFile,
Toast.LENGTH_LONG).show();
} catch (Exception error) {
Log.d("Error", "File" + filename + "not saved: "
+ error.getMessage());
Toast.makeText(context, "Image could not be saved.",
Toast.LENGTH_LONG).show();
}
Bitmap b = rotate(BitmapFactory.decodeFile(pictureFile.getAbsolutePath()),270);
FileOutputStream out = null;
try {
out = new FileOutputStream(pictureFile);
b.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
CameraPreview.safeToTakePicture = true;
galleryAddPic();
}
public static Bitmap rotate(Bitmap bitmap, int degree) {
int w = bitmap.getWidth();
int h = bitmap.getHeight();
Matrix mtx = new Matrix();
mtx.setRotate(degree);
return Bitmap.createBitmap(bitmap, 0, 0, w, h, mtx, true);
}
Anyway, it takes too long, I tried using mCamera.setDisplayOrientation(90); but it changes only the preview of the camera, the picture taken is still the same, I also tried getting the parameters of the camera and changing it like here:
Camera.Parameters parameters = mCamera.getParameters();
parameters.set("orientation", "portrait");
mCamera.setParameters(parameters);
Without success, any help will be appreciated.
EDIT :
New code:
#Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFileDir = getDir();
if (!pictureFileDir.exists() && !pictureFileDir.mkdirs()) {
Log.d("Error", "Can't create directory to save image.");
Toast.makeText(context, "Can't create directory to save image.",
Toast.LENGTH_LONG).show();
return;
}
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyymmddhhmmss");
String date = dateFormat.format(new Date());
String photoFile = "Picture_" + date + ".jpg";
String filename = pictureFileDir.getPath() + File.separator + photoFile;
pictureFile = new File(filename);
st1 = pictureFile.getAbsolutePath();
Bitmap b = rotate(BitmapFactory.decodeByteArray(data,0,data.length),270);
FileOutputStream out = null;
try {
out = new FileOutputStream(pictureFile);
b.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
CameraPreview.safeToTakePicture = true;
galleryAddPic();
}

Anyway, it takes too long
Your current algorithm looks like this:
Start with the photo in memory
Save the photo to disk, which is slow
Read the photo back in from disk to memory, which is slow
Rotate the reloaded photo
A more efficient approach would be:
Start with the photo in memory
Rotate the photo
BitmapFactory has decodeByteArray() to get a Bitmap back for rotation purposes.

saving an image file to a specific directory

I am building an android app that accesses the camera but i am wanting to save the image into a specific folder but i have no idea how to go about it. do i use a URI builder?
this is the code i have to get the image from the camera.
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photo = new File(Environment
.DIRECTORY_PICTURES), "pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, TAKE_PICTURE);

You can create a file from your own directory like this:
private File openFileFromMyDirectory() {
File imageDirectory = null;
String storageState = Environment.getExternalStorageState();
if (storageState.equals(Environment.MEDIA_MOUNTED)) {
imageDirectory = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "com.myapp.camera");
if (!imageDirectory.exists() && !imageDirectory.mkdirs()) {
imageDirectory = null;
} else {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault());
return new File(imageDirectory.getPath() +
File.separator + "IMG_" +
dateFormat.format(new Date()) + ".jpg");
}
}
return null;
}
Then get bitmap from uri:
Bitmap mCameraBitmap= MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
Finally save the bitmap into the file
private void saveImageToFile(File file) {
if (mCameraBitmap != null) {
FileOutputStream outStream = null;
try {
outStream = new FileOutputStream(file);
if (!mCameraBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream)) {
Toast.makeText(this, "Unable to save image to file.",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Saved image to: " + file.getPath(),
Toast.LENGTH_LONG).show();
}
outStream.close();
} catch (Exception e) {
Toast.makeText(this, "Unable to save image to file.",
Toast.LENGTH_LONG).show();
}
}
}

Captured image in portrait and get output in landscape in Directory

i am trying to save captured image in portrait mode ...
but not getting click how to do this?
here is my code...
captureImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
camera.takePicture(null, null, mPicture);
}
});
PictureCallback mPicture = new PictureCallback() {
#Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
System.out.println("picture file is null");
return;
}
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
// map.compress(Bitmap.CompressFormat.JPEG, 20, fos);
// fos.flush();
fos.close();
} catch (FileNotFoundException e) {
} catch (IOException e) {
}
}
};
and the outputmedia ...
private File getOutputMediaFile() {
File mediaStorageDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
"MyCameraApp");
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());
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "IMG_" + timeStamp + "_" + userId + ".jpg");
String imageName = "IMG_" + timeStamp + "_" + userId + ".jpg";
System.out.println("###### image is: " + imageName);
Intent intent = new Intent(this, VideoPlaybackActivity.class);
intent.putExtra("file_name", imageName);
intent.putExtra("data_type", "image");
intent.putExtra("fromClass", "Captured_Image");
intent.putExtra("expiry_time", "5");
intent.putExtra("cameraId", cameraId);
super.startActivity(intent);
finish();
return mediaFile;
}
i am getting image in my directory
but all images are in landscape mode.
so please if any body can help...

Creating folder with user input : Android

jpegCallback = new PictureCallback()
{
public void onPictureTaken(byte[] data, Camera camera)
{
//int imageNum = 0;
String Name = PatientInfo.getText().toString();
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File imagesFolder = new File(Environment.getExternalStorageDirectory().toString() + Name);
imagesFolder.mkdirs();
Date d = new Date();
CharSequence s = DateFormat.format("MM-dd-yy hh-mm-ss", d.getTime());
File output = new File(imagesFolder, s.toString() + ".jpg");
// String fileName = "image_" + String.valueOf(imageNum) + ".jpg";
// File output = new File(imagesFolder, fileName);
/* while (output.exists()){
imageNum++;
fileName = "image_" + String.valueOf(imageNum) + ".jpg";
output = new File(imagesFolder, fileName);
}*/
Uri uriSavedImage = Uri.fromFile(output);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
OutputStream imageFileOS;
try {
imageFileOS = getContentResolver().openOutputStream(uriSavedImage);
imageFileOS.write(data);
imageFileOS.flush();
imageFileOS.close();
Toast.makeText(AndroidCamera.this,
"Image saved: ",
Toast.LENGTH_LONG).show();
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{}
Log.d("Log", "onPictureTaken - jpeg");
}
};
This is a code example. I am trying to create folder with a userinput when it is entered. Each time i need to create new folders on entering new username. But in this there is something missing.Any suggestions will be helpful.

Change
File imagesFolder = new File(Environment.getExternalStorageDirectory().toString() + Name);
withFile
File imagesFolder = new File(Environment.getExternalStorageDirectory(), Name);
Please be sure to have also the WRITE_EXTERNAL_PERMISSION in the manifest, and that Name is not null
