【问题描述】：
我目前正在使用墙纸管理器设置墙纸，将位图传递给它，这是可行的，但此图像是静态的，因此它不会随屏幕移动，也没有给我裁剪图像的选项。我想在调用它的那一刻使用 ACTION_SET_WALLPAPER，它可以保存图像，但是当它尝试设置图像以裁剪它时，它给了我一个“无法加载图像”的祝酒词并退出我的应用程序，
我的尝试
Bitmap bitmap = ((BitmapDrawable) WallpaperView.getDrawable()).getBitmap();
Intent setAs = new Intent (Intent.ACTION_ATTACH_DATA);
setAs.setType("image/jpg");
ByteArrayOutputStream bytes = new
ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG,100,bytes);
File f = new File
(Environment.getExternalStorageDirectory()+ File.separator +
"/my_tmp_file.jpg");
try{
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
}catch (IOException e){
e.printStackTrace();
}
setAs.setDataAndType
(Uri.parse(Environment.getExternalStorageDirectory()+ File.separator +
"/my_tmp_file.png"),"image/jpg");
setAs.putExtra("mimeType", "image/jpg");
startActivity(Intent.createChooser(setAs, "Set Image
As"));
仍然倾注于此，我的代码保存了图像，然后询问用户想要将图像设置为什么，但随后由于 toast 无法加载图像而崩溃，如果我转到文件管理器，我可以选择我拥有的图像刚刚保存并设置为壁纸没问题有没有人可以告诉我为什么这不起作用？
