将结果ResultInfo {who = null，request = 0，result = 0，data = Intent {}}传递给活动java.lang.NullPointerException失败

Question

这是我在我的应用程序中用于打开图库和相机的代码。在没有设置的情况下按下后退按钮时应用程序崩溃 图片。建议我解决它。

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 0 && resultCode == RESULT_OK) {
            if (data != null) {

                // this is image view where you want to setimage
                bmp = (Bitmap) data.getExtras().get("data");

                ivKidsProfilePicture.setImageBitmap(bmp);

                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                bmp.compress(CompressFormat.JPEG, 100, baos);
                childpic = baos.toByteArray();

                Log.d("camera ---- > ", "" + data.getExtras().get("data"));
            }
            masterDatabaseAdapter.insertProfilePicture(childpic);



        }

        else {
            Uri selectedImage = data.getData();

            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String filePath = cursor.getString(columnIndex);
            cursor.close();

            if (bmp != null && !bmp.isRecycled()) {

                bmp = null;

            }

            bmp = BitmapFactory.decodeFile(filePath);
            ivKidsProfilePicture.setBackgroundResource(0);
            ivKidsProfilePicture.setImageBitmap(bmp);

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(CompressFormat.JPEG, 100, baos);
            childpic = baos.toByteArray();

        }
        masterDatabaseAdapter.insertProfilePicture(childpic);
    }
