无法将图片设置为. “没有app可以执行此操作"

问题描述

限时删除！！

我正在尝试为用户提供一个将图像设置为墙纸/whatsapp dp的选项，如下所示.

I am trying to give users an option to set image as wallpaper/whatsapp dp like this.

但是我被这段代码所困扰

But I'm stuck with this code

Uri sendUri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.a_day_without_thinking_mobile);

Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
intent.setDataAndType(sendUri, "image/jpg");
intent.putExtra("mimeType", "image/jpg");
startActivity(Intent.createChooser(intent,"Set As"));

它显示一个对话框，没有应用程序可以执行此操作.我也尝试通过这种方法检查我的Uri

It shows a dialog that no apps can perform this action.I also tried to check my Uri through this method

        ContentResolver cr = getContentResolver();
        String[] projection = {MediaStore.MediaColumns.DATA};
        Cursor cur = cr.query(sendUri, projection, null, null, null);
        if (cur != null) {
            if (cur.moveToFirst()) {
                String filePath = cur.getString(0);

                if (new File(filePath).exists()) {
                    Log.d("URI: ","File path exist");
                } else {
                    Log.d("URI: ","File not found");
                }
            } else {
                Log.d("URI: ","URI ok but no enty found");
            }
            cur.close();
        } else {
            Log.d("URI: ","URI was invalid for some other reason");
        }

并且总是返回URI无效.但是我确定该图像是有效的jpg，并且存在于原始文件夹中.我尝试更改URI路径，但没有成功.

And It always returned that the URI was invalid. But I'm sure that the image is valid jpg and is present in raw folder.I tried changing URI paths but to no success.
