Android Camera Intent: how to get full sized photo?


I am using intent to launch camera:

Intent cameraIntent = new Intent(
    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
getParent().startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

and using:

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
photoImage.setImageBitmap(thumbnail);
photoImage.setVisibility(View.VISIBLE);

But it is only a thumbnail, how do I get the full bitmap? I know I can use my own Activity and use:

Camera.PictureCallback()

But is there anyway to do it using Intent?

Thanks!

edit:

I also tried:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Uri uri = data.getData();
    imageView.setImageURI(uri);
}

It works for photo selected from gallery, but for camera intent, data.getData() returns null.


Solution

  • To get full sized camera image you should point camera to save picture in temporary file, like:

        private URI mImageUri;
    
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        File photo;
        try
        {
            // place where to store camera taken picture
            photo = this.createTemporaryFile("picture", ".jpg");
            photo.delete();
        }
        catch(Exception e)
        {
            Log.v(TAG, "Can't create file to take picture!");
            Toast.makeText(activity, "Please check SD card! Image shot is impossible!", 10000);
            return false;
        }
        mImageUri = Uri.fromFile(photo);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
        //start camera intent
        activity.startActivityForResult(this, intent, MenuShootImage);
    
    private File createTemporaryFile(String part, String ext) throws Exception
    {
        File tempDir= Environment.getExternalStorageDirectory();
        tempDir=new File(tempDir.getAbsolutePath()+"/.temp/");
        if(!tempDir.exists())
        {
            tempDir.mkdirs();
        }
        return File.createTempFile(part, ext, tempDir);
    }
    

    Then after image capture intent finished to work - just grab your picture from imageUri using following code:

    public void grabImage(ImageView imageView)
    {
        this.getContentResolver().notifyChange(mImageUri, null);
        ContentResolver cr = this.getContentResolver();
        Bitmap bitmap;
        try
        {
            bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, mImageUri);
            imageView.setImageBitmap(bitmap);
        }
        catch (Exception e)
        {
            Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
            Log.d(TAG, "Failed to load", e);
        }
    }
    
    
    //called after camera intent finished
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent)
    {
        //MenuShootImage is user defined menu option to shoot image
        if(requestCode==MenuShootImage && resultCode==RESULT_OK) 
        {
           ImageView imageView;
           //... some code to inflate/create/find appropriate ImageView to place grabbed image
           this.grabImage(imageView);
        }
        super.onActivityResult(requestCode, resultCode, intent);
    }
    

    P.S. Code need to be revised with respect to new security restriction applied in Android M - FileProvider: mImageUri has to be packed with FileProvider
