如何为质量下降的拍摄图像创建单独的文件夹

Question

您好，我正在尝试创建单独的文件夹，为捕获的图像没有失去质量使用下面的代码，但我得到了例外android。操作系统。FileUrieExposedException：file:///storage/emulated/0/myFolder/photo_20180504_102426.png通过ClipData在应用程序之外公开。项目getUri（）

有人能纠正我的代码吗

String folder_main = "myFolder";
            File f = new File(Environment.getExternalStorageDirectory(), folder_main);
            if (!f.exists()) {
                f.mkdirs();
            }
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            File file = new File(Environment.getExternalStorageDirectory(), "/myFolder" + "/photo_" + timeStamp + ".png");
            imageUri = Uri.fromFile(file);

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            startActivityForResult(intent, Constants.CAMERA_REQUEST_CODE);

 private void onCaptureImageResult(Intent data) {

        try {

            Bitmap thumbnail = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
            CircleImageView circleImageView = findViewById(formFields.get(imagePosition).getId());
            circleImageView.setImageBitmap(thumbnail);
}

把这个放在你的oncreate（）上

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
