我尝试手动共享sdcard中的图像,但是无法提供错误 加载图片
String uri="file:///storage/emulated/0/Ingreets/20161227165518.jpeg"
Uri u = Uri.parse (uri);
Intent shareIntent = new Intent (Intent.ACTION_SEND);
shareIntent.setType ("image/*");
shareIntent.putExtra (Intent.EXTRA_STREAM, u);
shareIntent.setPackage ("com.instagram.android");
startActivity(Intent.createChooser(shareIntent, "Share to"));
