您好，我正在尝试通过彩信从 sdcard 发送图像（png）。我正在使用 ACTION_SEND 意图，但它似乎不起作用。
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra("sms_body", "Sent using Spootur");
sendIntent.setType("image/png");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(imagePath));
startActivityForResult(sendIntent, SEND_ACTIVITY);
我知道 imagePath 的值为 /mnt/sdcard/Spootur/Pictures/6799abd6-df22-4017-89e1-d9e529790fd8.png，它指向一个现有文件。
选择菜单出现时，我选择我的消息传递应用程序（处理程序），但它给了我一个“抱歉，您无法将此图片添加到您的消息”错误。我尝试使用其他应用程序，我得到的压倒性结果是我给它的资源是“不受支持的文件类型”。我不知道为什么会发生这种情况，因为我明确地将 MIME 类型设置为 .png 图像。
有任何想法吗？以下是有问题的各种应用程序的一些 logcat 日志：
