camera captured image intent to other activity?

Question

Its very common question seen on StackOverflow and I have tried almost every solution on SO. I still get a NullPointerExeption in onAtivityResult- data.

I have tried:

The last code which I have tried for fourth time is given below:

On Button Click:

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                File file=getOutputMediaFile(1);
                picUri = Uri.fromFile(file); // create
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, picUri); // set the image file
                    startActivityForResult(cameraIntent, REQUEST_TAKE_PHOTO);

getOutputMediaFile()

 private  File getOutputMediaFile(int type) {
        File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES), "MyApplication");

        /**Create the storage directory if it does not exist*/
        if (!mediaStorageDir.exists()) {
            if (!mediaStorageDir.mkdirs()) {
                return null;
            }

        }
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        File mediaFile;
        if (type == 1){
            mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                    "IMG_"+ timeStamp + ".png");
        } else {
            return null;
        }

        return mediaFile;
    }

onActivityResult()

 protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        if (resultCode == RESULT_OK && requestCode == REQUEST_TAKE_PHOTO && intent != null){


            Uri selectedImage = intent.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            //file path of captured image
            imagepath = cursor.getString(columnIndex);
            //file path of captured image
            File f = new File(imagepath);
            String filename = f.getName();
            cursor.close();
            Bitmap imageData = BitmapFactory.decodeFile(filename);
//            Bitmap imageData = (Bitmap) data.getExtras().get("data");

            Intent i = new Intent(this, EditImageActivity.class);
            i.putExtra("path", imageData );
            startActivity(i);
        }
    }
}

Please suggest something better which is not mentioned in above links which I already have referred because that didn't work for me.

I am using Android Atudio, with api 10+.

hi please try below code hope it will help you,

private final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;
private final int MEDIA_TYPE_IMAGE = 1;

intent code for capture image

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
m_fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, m_fileUri);
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);


public Uri getOutputMediaFileUri(int p_type)
{
    return Uri.fromFile(getOutputMediaFile(p_type));
}


private File getOutputMediaFile(int p_type)
{
    File m_mediaFile;
    if (p_type == MEDIA_TYPE_IMAGE)
    {

            m_buffer = new StringBuffer();

            m_buffer.append(Environment.getExternalStorageDirectory().getPath() + File.separator).append("Image");
            File m_imageStorageFile = new File(m_buffer.toString());

            // Create the storage directory if it does not exist
            if (!m_imageStorageFile.exists())
            {
                if (!m_imageStorageFile.mkdirs())
                {
                    return null;
                }
            }
            // Create a media file name
            String m_timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new java.util.Date());
            m_buffer = new StringBuffer();
            m_buffer.append(m_imageStorageFile.getPath()).append(File.separator).append("IMG_").append(m_timeStamp).append(".jpg");
            m_mediaFile = new File(m_buffer.toString());

    }
    else
    {
        return null;
    }

    return m_mediaFile;
}

write below code in your onActivityResult

protected void onActivityResult(int p_requestCode, int p_resultCode, Intent p_data)
{
        super.onActivityResult(p_requestCode, p_resultCode, p_data);
        if (p_resultCode == RESULT_OK)
        {
            switch (p_requestCode)
            {
                case CAMERA_CAPTURE_IMAGE_REQUEST_CODE:
                    m_selectedPath = m_fileUri.getPath();
                break;

            }
        }
}

Constant.MEDIA_DIRECTORY_PATH contains your directory path example :- mnt/sdcard0/android/com.example

can u please explain what is Constant in code ? @Android WebLineindia – Drashti Oct 12 '15 at 12:22
what should be its type ? its showing cannot resolve symbol Constant. @AndroidWeblineindia – Drashti Oct 12 '15 at 12:59
dont use constant , i have updated my answer please check . – Oct 12 '15 at 13:03
`String m_timeStamp = new SimpleDateFormat(Constant.TIME_STAMP_FORMAT, Locale.getDefault()).format(new java.util.Date());` its in your updated answer - @AndroidWeblinindia – Drashti Oct 13 '15 at 05:22
and what should write on other activity where the captured image has to display. @AndroidWeblinindia – Drashti Oct 13 '15 at 05:30
thanks it worked.. i cant vote so i commented here... but tell me about that m_timeStamp i have commeted that line, what should i write on behalf of Constant at there. @AndroidWeblinindia – Drashti Oct 13 '15 at 05:37
Use "yyyyMMdd_HHmmss" instead of Constant.TIME_STAMP_FORMAT. Also if it worked fine for you pl accept and upvote the answer so that it can be helpful for others too. – Oct 13 '15 at 05:42
showing cannot resolve "yyyyMMdd_HHmmss" @AndroidWeblinindia – Drashti Oct 13 '15 at 05:49
Pl explain properly all the require things you want , I have explained what you actually needed. Or pl share what actual errors you are getting. – Oct 13 '15 at 06:27
you have mentioned that `Use "yyyyMMdd_HHmmss" instead of Constant.TIME_STAMP_FORMAT` i have appied that and it shows error that `CAN NOT RESOLVE SYMBOL yyyyMMdd_HHmmss` @@AndroidWeblinindia – Drashti Oct 13 '15 at 06:52
Pl share your code , I think you have implemented some thing wrong. And I have edited above answer so check once. – Oct 13 '15 at 08:35

You are getting NullPointerException because when user goes to camera intent and by the time he captures the image the activity on which camera intent was hosted gets destroyed or recreated when user comes back from the camera intent. Duw to which picUri (path of image created from camera intent) returns null as no such object is in memory right now.

Save path of image like this :

@Override
protected void onSaveInstanceState(Bundle savedInstanceState) {

    if(mImageCaptureUri!=null)
        savedInstanceState.putString("camera_image", picUri.toString());

    super.onSaveInstanceState(savedInstanceState);
}

And Retrieve image path from this :

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {

    if (savedInstanceState != null) {
        if (savedInstanceState.containsKey("camera_image")) {
            picUri = Uri.parse(savedInstanceState.getString("camera_image"));
        }
    }

    super.onRestoreInstanceState(savedInstanceState);
}

sorry m new in anddroid and i didnt use this two method can you please explain how to use and where to put this ? and if we use this then no need to use onActivityResult method? -@vipul_asri — Drashti, Oct 12 '15 at 12:25
No, these methods are an addition to `onActivityResult()` method. You have to put these methods in the Activity just like `onActivityResult()` — Vipul Asri, Oct 12 '15 at 12:53

camera captured image intent to other activity?
