Question

我正在尝试拍照并将其保存到外部存储空间，然后我保存照片的路径以加载此照片以使用个人资料图片。

public void capture()
        {
            Intent intent = new Intent();
            intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            File f = getExternalFilesDir(Environment.DIRECTORY_PICTURES);




            file = new File(f, "img_" + timeStamp+".jpg");

            photoUri = FileProvider.getUriForFile(EditProfileActivity.this,
                    BuildConfig.APPLICATION_ID + ".provider",
                    file);

            intent.putExtra("data", photoUri);
            //Log.i("Pathfewffewf",file.getPath());
            startActivityForResult(intent,0);
        }
        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == 0 && resultCode == RESULT_OK) {

                if (data != null) {


                    Bitmap photo = (Bitmap) data.getExtras().get("data");
                    Bitmap circleBitmap = Bitmap.createBitmap(photo.getWidth(), photo.getHeight(), Bitmap.Config.ARGB_8888);

                    BitmapShader shader = new BitmapShader(photo, TileMode.CLAMP, TileMode.CLAMP);
                    Paint paint = new Paint();
                    paint.setShader(shader);
                    paint.setAntiAlias(true);
                    Canvas c = new Canvas(circleBitmap);
                    c.drawCircle(photo.getWidth() / 2, photo.getHeight() / 2, photo.getWidth() / 2, paint);
                    imageView.setImageBitmap(circleBitmap);




                }
            }

然后我

            Bitmap myBitmap = BitmapFactory.decodeFile(user.getmImage());



            image.setImageBitmap(myBitmap);

我在保存图像时加上日志消息，当它加载图像时

它有相同的路径，但它说没有这样的文件或目录...... 我认为文件无法正常保存我应该做什么

Android拍照并保存到外部存储
