android camera : Failure delivering result ResultInfo{who=null, request=0, result=-1, data=null} to activity

Question

i've really frustased to solve my problem, i have an application that using camera, when camera capture a photo, it will display on activity, when i'm not using cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri); photo will display on activity, but the name and path file is not like what i wanted. i'm using galaxy tab for compiling it, i have follow tutorial to solve my problem from here , here and here but my application still force close and eror, this is my code :

{
    File sdCard = Environment.getExternalStorageDirectory();
    File path = new File (sdCard.getAbsolutePath() + "/android/data/spaj_foto");
    path.mkdir();
    File file = new File (path,"spaj_foto.png");
    String filePath ="/android/data/spaj_foto/spaj_foto.png";

    try {
        file.createNewFile();
    } catch (IOException e) {}       


    mPhotoUri = Uri.fromFile(file); 
    values.put(MediaStore.Images.ImageColumns.DATA, file.getPath());
    mPhotoUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
    startActivityForResult(cameraIntent,TAKE_PHOTO_CODE );  

}

activityresult method :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        image_spaj.setImageBitmap(photo);


        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);

        // CALL THIS METHOD TO GET THE ACTUAL PATH
        File finalFile = new File(getRealPathFromURI(tempUri));

//              System.out.println(mImageCaptureUri);
    }  
}
public String getRealPathFromURI(Uri mPhotoUri) {
    Cursor cursor = getContentResolver().query(mPhotoUri, null, null, null, null); 
    cursor.moveToFirst(); 
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
    return cursor.getString(idx); 
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

this is my logcat says:

Solution 1

Make sure you have both Camera Permission and READ/WRITE External Storage Permissions.

Try this is working like charm with me

private String selectedImagePath = "";
    final private int PICK_IMAGE = 1;
    final private int CAPTURE_IMAGE = 2;

public Uri setImageUri() {
        // Store image in dcim
        File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".png");
        Uri imgUri = Uri.fromFile(file);
        this.imgPath = file.getAbsolutePath();
        return imgUri;
    }


    public String getImagePath() {
        return imgPath;
    }

btnGallery.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent();

                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);

            }
        });

        btnCapture.setOnClickListener(new OnClickListener() {

Try this, Yesterday i had same problem. using below code i rectify problem. just try on it.

Note : And also add configChanges for particular activity. while calling the camera intent activity will be refreshed. you need to avoid that. android:configChanges="orientation|keyboardHidden|screenSize"

btnGallery.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
           intent = new Intent(Intent.ACTION_PICK);
                            intent.setType("image/*");
                            startActivityForResult(intent, 1);
        }
    });

    btnCapture.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent(
                                    MediaStore.ACTION_IMAGE_CAPTURE);
                            File file = new File(Environment
                                    .getExternalStorageDirectory(),
                                    "test.jpg");

                            outputFileUri = Uri.fromFile(file);

Solution 3

I think following line causes the issue.

Bitmap photo = (Bitmap) data.getExtras().get("data"); 

You pass the file uri already as following

cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);

When you pass EXTRA_OUTPUT with a URI, the intent you receive in onActivityResult() will be null. If you want to get image in this method, fetch image with the path you pass with EXTRA_OUTPUT.

Solution 4

More cleaner code , might help someone looking for answer , basically when you save file to external storage bundle no more has bitmap in result , instead you have to load from file

String fileName;
.
. 
private void takePicture() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File

        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    Uri.fromFile(photoFile));
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)        {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {

       loadImageFromFile();
    }
}
public void loadImageFromFile(){

    ImageView view = (ImageView)this.findViewById(R.id.imageViewHeader);
    view.setVisibility(View.VISIBLE);


    int targetW = view.getWidth();
    int targetH = view.getHeight();

    // Get the dimensions of the bitmap
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(fileName, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW/targetW, photoH/targetH);

    // Decode the image file into a Bitmap sized to fill the View
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(fileName, bmOptions);
    view.setImageBitmap(bitmap);
}
private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    fileName =  image.getAbsolutePath();
    return image;

[Aoyama Nanami]

thank you for your help... but i have one question, why when i capture another image, this is not rewrite the image that have created before?

[Biraj Zalavadia]

because we generate unique uri in this method setImageUri() by appending current time milliseconds. If you want to overwrite the file give static hard coded file name in setImageUri() method.

[Aoyama Nanami]

i have made like this : File file = new File(Environment.getExternalStorageDirectory() +"/android/data/spaj_foto/spaj_foto.png"); Uri imgUri = Uri.fromFile(file); this.imgPath = file.getAbsolutePath();

[RichArt]

This helped. Thank you! I was still trying to Bitmap picture = (Bitmap) data.getExtras().get("data");

[Andro Selva]

This really works. I started facing crash issue on Android 7.0 and removing this line did the trick. Also removing this line didn't affect pre-nougat devices as well. Tested from Android 4.4 and above.

[rajat singh]

This will not work like a charm for the Android version running above Android N, only working for the Android Versions below N
