Capture image from camera return low quality image

I've been developed app to take a picture to be saved in gallery. I've searched online and the easiest way that I could practice was to use data.getExtras().get("data") . So below are the code to take picture from camera. Note that I'm using fragment in this class.
img22a1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,CAMERA_01);
}
});
Get the captured image and convert it to string
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_01) {
if (resultCode == Activity.RESULT_OK) {
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream output = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, output);
byte[] byte_arr = output.toByteArray();
((SiteProgress) getActivity().getApplication()).seti22a1(Base64.encodeToString(byte_arr, Base64.DEFAULT));
BitmapDrawable ob = new BitmapDrawable(getResources(), bitmap);
img22a1.setBackgroundDrawable(ob);
} else if (resultCode == Activity.RESULT_CANCELED) {
}
}
}
I save the string into global variable so another activity can access it.
In another activity, I have a button to save the image into folder/gallery by accessing the image string.
for(int i=0;i<=namefile.length;i++){
Bitmap[] bitmap = new Bitmap[namefile.length];
FileOutputStream outputStream = new FileOutputStream(String.valueOf(namefile[i]));
bitmap[i] = BitmapFactory.decodeByteArray(decodedString[i],0,decodedString[i].length);
bitmap[i].compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.close();
MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), namefile[i].getAbsolutePath(), namefile[i].getName(), namefile[i].getName());
}
It worked to save the image into folder/gallery....But the quality of image was very low...I could barely see text in the image.
They said data.getExtras().get("data") supposed to return thumbnail and not the actual image. What I want here is to get the full image and not the thumbnail one.
Any answer will be very appreciated.

From: Android - How to get the image using Intent data
if(data != null)
{
Uri selectedImageUri = data.getData();
filestring = selectedImageUri.getPath();
Bitmap thumbnail = BitmapFactory.decodeFile(filestring, options2);
System.out.println(String.format("Bitmap(CAMERA_IMAGES_REQUEST): %s", thumbnail));
System.out.println(String.format("cap_image(CAMERA_IMAGES_REQUEST): %s", cap_image));
cap_image.setImageBitmap(thumbnail);
}

How can I send a jpg picture from android app to a matlab server?

I have an application with one simple button which allows to take a picture. I want to send this picture to a matlab server. Here is my code:
button = (Button) findViewById(R.id.uploadButton);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Toast.makeText(MainActivity.this,"Try Toast",Toast.LENGTH_LONG).show();
//Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
//startActivity(intent);
Intent cameraIntent = new Intent (MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
And this the others method:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
//did the user choose ok? If so, the code inside these curly braces will execute.
if (resultCode == RESULT_OK){
if (requestCode == CAMERA_REQUEST){
//we are hearing back from the camera
Bitmap cameraImage = (Bitmap) data.getExtras().get("data");
//at this point we have the image from the camera.
//imgSpecimenPhoto.setImageBitmap(cameraImage);
Bitmap bJPGcompress = codec(cameraImage, Bitmap.CompressFormat.JPEG, 100);
imgSpecimenPhoto.setImageBitmap(bJPGcompress);
}
}
}
private static Bitmap codec(Bitmap img, Bitmap.CompressFormat format,
int quality) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
img.compress(format, quality, baos);
byte[] array = baos.toByteArray();
return BitmapFactory.decodeByteArray(array, 0, array.length);
}

Convert the data received by camera into a bitmap in android

What i am having: i am using a camera to capture a image and i want to display it in a listview by passing bitmap to adapter in android
private void startCameraCapture() {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getActivity().getPackageManager()) != null) {
startActivityForResult(cameraIntent, 1024);
}
}
public void onActivityResult(int requestCode, int resultCode, Intent myData) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 1024) {
.............. mycode
}
}
What i want to do :: i want to convert the data i received as myData into a bitmap in android

Convert byte[] to bitmap
Bitmap bmp = myData.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

onActivityResult is not calling after taking camera picture

I am doing an android app, in which I have a functionality that, I need to open camera and take a picture. After taking picture onActivityResult is not called. my screen remains only in camera state.
My code:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File mediaFile = new File(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI.getPath());
Uri imageUri = Uri.fromFile(mediaFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, 1);
onActivityResult code
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null && !data.toString().equalsIgnoreCase("Intent { }"))
switch (requestCode) {
case 1:
Log.i("StartUpActivity", "Photo Captured");
Uri uri = data.getData();
String imgPath = getRealPathFromURI(uri);
bitmap = (Bitmap) data.getExtras().get("data");
MediaStore.Images.Media.insertImage(getContentResolver(),
bitmap, null, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
img1.setImageBitmap(bitmap);
}
}

onActivityResult is probably called, but the statements inside your if statement and switch/case statements are not being executed, because they are never reached.
The code below includes two methods takePhoto and onActivityResult, is very short and works perfectly. Take a look at it, it probably will help you!
public void takePhoto(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}

You can run your application in debug mode, after putting a breakpoint in onActivityResult method,
if it's stopping there after getting from the Camera then it's being called successfully.
and you could just change the if statement you're using making your code like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null && resultCode = RESULT_OK)
switch (requestCode) {
case 1:
Log.i("StartUpActivity", "Photo Captured");
Uri uri = data.getData();
String imgPath = getRealPathFromURI(uri);
bitmap = (Bitmap) data.getExtras().get("data");
MediaStore.Images.Media.insertImage(getContentResolver(),
bitmap, null, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
img1.setImageBitmap(bitmap);
}
}
and note that it is more recommended to using final ints as the request code instead of rewriting them everytime they're needed
like :
private final int START_CAMERA_REQUEST_CODE = 1;

I think this may be help you
Follow Below Code step by step and compare with your code to avoid null exception
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);
1 OnActivity Result
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 1)
onCaptureImageResult(data);
}
}
2
onCaptureImageResult
public void onCaptureImageResult(Intent data) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
Uri tempUri = getImageUri(getApplicationContext(), thumbnail); // call getImageUri
File finalFile = new File(getRealPathFromURI(tempUri));
file_path = finalFile.getPath().toString(); // your file path
imgview.setImageBitmap(thumbnail);
// this code will get your capture image bitmap}
3 getImageUri
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null); // your capture image URL code
return Uri.parse(path);
}
Using this code your screen will not remain more on camera state it will finish and image will be load as well you get image URL.

Bitmap mBitmap = BitmapFactory.decodeFile(imgPath);
pass Image path which you create from URI.

Probably, your activity is reloaded after camera is finished, but your code is not prepared to such situation.
See Android startCamera gives me null Intent and ... does it destroy my global variable?.

I think onActivity is called but it doesn't go into the if condition
Check only for null in if condition:
if (data != null )
switch (requestCode) {
case 1:
Log.i("StartUpActivity", "Photo Captured");
Uri uri = data.getData();
String imgPath = getRealPathFromURI(uri);
bitmap = (Bitmap) data.getExtras().get("data");
MediaStore.Images.Media.insertImage(getContentResolver(),
bitmap, null, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
img1.setImageBitmap(bitmap);
}

From where you are calling startActivityForResult(intent, 1),
and where you Overriding onActivityResult() ?
I mean if you call startActivityForResult() from Frgment then you should override onActivityResult() in fragment it self, same applies to Activity also.

save image from bytes returned from android camera intent is saved as small image

I am trying to capture an image using Android Camera Intent. Camera intent returns Byte Array and when I saved the byte array as a Bitmap, I am getting a very small image instead of getting an Image based on current camera settings (1024 Pixels currently set in the android mobile camera).
Usally i will get file path from the camera intent but somehow i am not getting from this device, so i am creating the bitmap from the byte returned by camera intent.
Anybody knows why is this and how to solve this issue. Thanks.
The below is the java code block I am using.
private Intent cameraIntent = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_PIC_REQUEST) {
if (resultCode == RESULT_OK) {
if ( data != null)
{
Bitmap myImage = null;
Bitmap imageBitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100,stream);
byte[] byteArray = stream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
myImage = BitmapFactory.decodeByteArray(byteArray, 0,byteArray.length, options);
fileOutputStream = new FileOutputStream(sPath);
BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
myImage.compress(CompressFormat.JPEG, 100, bos);
bos.flush();
bos.close();
}
}
}
}

The data.getExtras("data") only returns a thumbnail image. To obtain the full-sized image, you need to pass the camera intent a file in which to store that image and later retrieve. A rough example follows.
Start the intent:
File dir = new File(Environment.getExternalStorageDirectory() + "/dcim/myappname");
File mFile = File.createTempFile("myImage", ".png", dir);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mFile));
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
Inside onActivityResult:
if (resultCode == RESULT_OK) {
Bitmap bm = BitmapFactory.decodeFile(mFile.getAbsolutePath());
}
// do whatever you need with the Bitmap
Keep in mind that mFile will have to be global or somehow persisted so that it may be called upon where necessary.
