How to get image from camera

I have tried many codes from stackoverflow and internet.But I am able to find how to pick image from camera.I have used the following code,but data.getData() always returns null.Dont know how to solve.Pleas help this.
Intent takePictureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, PICK_IMAGE_CAMERA1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == 30 && resultCode == Activity.RESULT_OK&&data!null)
{
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
imageView.setImageBitmap(imageBitmap);
}
}

Try this code #Thrishool,
private static final int CAMERA = 1;
//choosing the image from camera
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA);
//now get the data from the onActivity result
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
imageview.setImageBitmap(thumbnail);
ByteArrayOutputStream baos=new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.PNG,100, baos);
byte [] b=baos.toByteArray();
String temp = Base64.encodeToString(b, Base64.DEFAULT);
Log.e("savedImage",temp);
Toast.makeText(ProfileActivity.this, "Image Saved!", Toast.LENGTH_SHORT).show();
}
}
Try this and let me know #Thrishool

Image Saved to Gallery After Being Captured

Hy,,, this has been confused me for a while since what I intended to do with my app was just to capture images and upload it without saving it into the gallery. But what happen is the opposite.
This is how I call the camera function
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,CAMERA_01);
And this is how I handle the request
#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();
i11a1 = Base64.encodeToString(byte_arr, Base64.DEFAULT);
((SiteBefore)getActivity().getApplication()).seti11a1(i11a1);
BitmapDrawable ob = new BitmapDrawable(getResources(),bitmap);
img11a1.setBackgroundDrawable(ob);
}else if(resultCode == Activity.RESULT_CANCELED){
}
}
}
This code is written inside the fragment class. This cause the image being saved into the gallery. Anyone know what causes this?

Data not return from Google Photo Intent android

I have been trying to load an image from Google Photos App into my application. When I choose an image in Google Photos, my application crashes, but if I select the image from the Gallery App, it works. Please what am I missing out? Find my code below.
itemImage.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
pickImage();
}
});
public void pickImage() {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.putExtra("crop", "true");
galleryIntent.putExtra("outputX", 100);
galleryIntent.putExtra("outputY", 100);
galleryIntent.putExtra("scale", true);
galleryIntent.putExtra("return-data", true);
// Start the Intent
startActivityForResult(galleryIntent, 1);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null) {
try {
//Uri uri = data.getData();
Bitmap bmp = (Bitmap) data.getExtras().get("data");
itemImage.setImageBitmap(bmp);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
bytarray.length);
} catch (Exception e){}
}
}
I have tweaked the code a little bit. Now I can import all images on the Gallery and Photos app except for camera images. See my new code below:
public void pickImage() {
// Create intent to Open Image applications like Gallery, Google Photos
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, 1);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null) {
try {
//Uri uri = data.getData();
final Uri uri = data.getData();
final InputStream imageStream = getActivity().getContentResolver().openInputStream(uri);
final Bitmap bmp = BitmapFactory.decodeStream(imageStream);
itemImage.setImageBitmap(bmp);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);
byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
/*bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
bytarray.length);*/
} catch (Exception e){}
}
}

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);
}

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.
