小白请问这串代码哪里出了问题？为什么不能将图片储存进手机？

```photo_button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                checkPermission_Camera();
                //Action here
            }
        });

```private void checkPermission_Camera(){
RxPermissions rxPermissions = new RxPermissions(ObjectInformationActivity.this);
rxPermissions.request(android.Manifest.permission.CAMERA)
.subscribe(new io.reactivex.functions.Consumer() {
@Override
public void accept(Boolean aBoolean) throws Exception {
if (aBoolean) {
// 用户已经同意该权限
takePhoto();
} else {
// 用户拒绝了该权限，并且选中『不再询问』
ToastUtils.showLong(getResources().getString(R.string.ask_for_permission));
}
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode==RESULT_OK&&requestCode==REQUEST_CODE_CAMERA) {
Toast.makeText(this, "保存照片成功", Toast.LENGTH_SHORT).show();
Bitmap bitmap =(Bitmap) Objects.requireNonNull(data.getExtras()).get("data");
picture_of_object.setImageBitmap(bitmap);
}
super.onActivityResult(requestCode, resultCode, data);
}}

    private void takePhoto(){
        //初始化照片路径
         Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
         File file = new File(getExternalFilesDir(null)+File.separator+"myPicture");
            if(!file.exists()){
            file.mkdirs();
            }
            String pictureName =new SimpleDateFormat("yyyyMMddHHmmss").format(new Date())+".jpg";
            File saveFile= new File(file,pictureName);
            uri = FileProvider.getUriForFile(this,"univ.buaa.icabinet.activity",saveFile);
            intent.putExtra(MediaStore.EXTRA_OUTPUT,uri);//根据这个uri保存照片
            startActivityForResult(intent,REQUEST_CODE_CAMERA);//结果返回onActivityResult函数
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(resultCode==RESULT_OK&&requestCode==REQUEST_CODE_CAMERA) {
            Toast.makeText(this, "保存照片成功", Toast.LENGTH_SHORT).show();
            Bitmap bitmap =(Bitmap) Objects.requireNonNull(data.getExtras()).get("data");
            picture_of_object.setImageBitmap(bitmap);
        }
        super.onActivityResult(requestCode, resultCode, data);
    }}

你什么问题啊，不同版本，对照片返回的图片的获取也不一样

用代码刷新一下SD卡 试试

你有加入读写SD卡的权限吗……我看你只有调用相机的权限
< uses-permission android：name =“android.permission.WRITE_EXTERNAL_STORAGE”/>

需要看错误日志是什么：1、看有没有文件读写权限；2、看拍照路径是否正确
