No callback for startActivityForResult in case of MediaStore.INTENT_ACTION_VIDEO_CAMERA

The case is when user selects camera, he has the flexibility to either capture image or record video and the user shall be able to show the same in one's app.
For this case, MediaStore.INTENT_ACTION_VIDEO_CAMERA intent is used but no callback comes in either case of capturing image or recording video.
Intent intent = new Intent(MediaStore.INTENT_ACTION_VIDEO_CAMERA);
startActivityForResult(intent, VIDEO_CAMERA);
For getting result, code used as follows:-
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_CANCELED) {
return;
}
if (resultCode == RESULT_OK) {
if (requestCode == VIDEO_CAMERA) {
Uri uri = data.getData();
}
}
}

To start the camera and get the result back in onActivityResult(), you should create an Intent with MediaStore.ACTION_IMAGE_CAPTURE:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Similarly, to capture a video, use MediaStore.ACTION_VIDEO_CAPTURE

I finally found a solution and it is as follows:-
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
Intent chooserIntent = Intent.createChooser(takePictureIntent, "Capture Image or Video");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[]{takeVideoIntent});
startActivityForResult(chooserIntent,VIDEO_CAMERA);
And finally receives the callback in onActivityResult and I got the uri in this way:-
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_CANCELED) {
return;
}
if (resultCode == RESULT_OK) {
if (requestCode == VIDEO_CAMERA) {
Uri uri;
if (data == null || data.getData() == null) {
Bitmap bitmap (Bitmap)data.getExtras().get("data");
// TODO:Get uri from bitmap for image
uri = getImageUri(context, bitmap);
} else {
//Get uri for video
uri = data.getData();
}
}
}
}

Android picker intent returns URI of low quality image (thumbnail) Note 8

I am facing a strange issue and I hope someone can help me out.
I have a app which the user can select a picture from the gallery and them make some editions.... The problem happens on some devices, the returned URI of the picture loads a thumbnail of the picture.
On my Note 8 (with dynamic focus mode, AKA Portrait mode) it always returns the thumbnail of those pictures. I have no idea why.
My code:
private void openGallery(){
Intent pickPhotoIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
try{
startActivityForResult(pickPhotoIntent, PICK_IMAGE_REQUEST);
}catch (ActivityNotFoundException e){
FirebaseCrash.report(e);
if(mToast != null)
mToast.cancel();
mToast = Toast.makeText(getApplicationContext(),getResources().getText(R.string.no_gallery),Toast.LENGTH_LONG);
mToast.show();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == REQUEST_PRO){
if(resultCode == RESULT_OK){
AnalyticsManager.UserEnteredIn(FirebaseAnalytics.getInstance(this),AnalyticsManager.PRICE);
billingProcessor.purchase(Home.this,ImageXY.APESCT_PRO);
}
}
else if(requestCode == PICK_IMAGE_REQUEST){
if(resultCode == RESULT_OK){
if(data != null && data.getData() != null){
onImageReceived(data.getData());
}else
Toast.makeText(getApplicationContext(),"Image Loading Error",Toast.LENGTH_SHORT).show();
}
}
if (!billingProcessor.handleActivityResult(requestCode, resultCode, data))
super.onActivityResult(requestCode, resultCode, data);
}
public void onImageReceived(Uri imageUri) {
Reference.image_uri = imageUri;
Log.d("PICKER","RETURNED");
Intent i = new Intent(getApplicationContext(),ImageEditingActivity.class);
startActivity(i);
}
Thanks in advance, I hope someone can help me.

camera activity does not return to the previous/caller activity

I read an text input from the user, this input i use it as a name of a picture i'm taking by the camera.
i store this name and the path of the image name into Sqlite Database.
what I'm trying to do is, after clicking OK to accept the taken picture, i want the saved path to be displayed in a toast.
the problem is, when I click OK to accept the picture, nothing is being displayed and i cant switch from the camera activity to the activity that called the camera activity"the previous activity"
Note: I'm using the emulator not a real device.
OnClickListener btn_TakePictureListener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String imgPath = retrievePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, getImageUri(imgPath));
startActivityForResult(intent, RequestCode);
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RequestCode && resultCode == RESULT_OK) {
String s = data.getData().toString();
Toast.makeText(getBaseContext(), ""+s, Toast.LENGTH_SHORT).show();
}
}

if you are passing Uri for you image then you can retrieve image as taken by camera:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(
Environment.getExternalStorageDirectory(), "temp.jpg")));
startActivityForResult(intent, 1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
// Set the file save path with directory
File picture = new File(Environment.getExternalStorageDirectory()
+ "/temp.jpg");
Uri imageuri= Uri.fromFile(picture);
//set to imageview here
}
}
EDIT:
For Getting data uri in onActivityResult start Camra Activiyt as:
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,IMAGE_UNSPECIFIED);
startActivityForResult(intent, 2);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
Uri uriimg = data.getData();
Toast.makeText(getBaseContext(), ""+uriimg.toString(), Toast.LENGTH_SHORT).show();
}
}

How to get to the previous screen on cancelling taking a picture?

I am using an intent to call camera and onresult to get the captured image, but if the image is not taken (on pressing cancel), i want to get back to the screen where i called the camera from
i am using this right now....but is there a better way to do this:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (!(data == null || resultCode == 0)) {
if (requestCode == CAMERA_REQUEST) {
photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
} else {
Intent intent = new Intent(ImageUploaderActivity.this,
ImageUploaderActivity.class);
startActivity(intent);
finish();
}
}

I am doing something similar in my app and here is my code:
if (resultCode == RESULT_OK) {
if (data != null) {
//When all was ok
}
} else if (resultCode == RESULT_CANCELED) {
//When it was canceled, when I press a back button while in camera app.
} else {
//Some other result
}

Intercepting onActivityResult() for Camera application on Android

In my application, I'm trying to make it so the User can press a button, which will allow them to take a picture using the stock camera application on their phone.
I am following the guide to using an external Camera app to capture images that I can use in my own app from the Android Developers Guide (http://developer.android.com/guide/topics/media/camera.html#intent-receive)
I'm having trouble with the onActivityResult() method, it apparently takes in 3 parameters
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if(resultCode == RESULT_OK) {
Log.w("borre","Image saved to:\n" + data.getData());
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
}
But at the moment, the data Intent is coming back as null, so calling any methods on the Intent parameter throws a NullPointerException
Here's the code I'm using to call up the Camera application (It's basically the same as the code in the guide)
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
Has anyone had this problem or knows why this Intent is coming back as null?

your are getting data part null bez you are not setting intent.setDataAndType() when you are starting Acitivty.like
public static final String IMAGE_UNSPECIFIED = "image/*";
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);
startActivityForResult(intent, 3);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == 0)
return;
if (requestCode == 2) {
Uri uri=data.getData(); //YOU GET DATA HERE
}
//OR
if (requestCode == 3) {
Bundle extras = data.getExtras();
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);// (0 - 100)????
imageView.setImageBitmap(photo);
}
}
or in your case getting image path use:
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
//pic path
File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg");
}
