使用意图导致崩溃共享链接

Question

我正在尝试使用intent发送链接。但点击分享按钮后，应用程序崩溃了。这是我的代码

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "example.com");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Check out this site!");
startActivity(Intent.createChooser(intent, "Share Using"));

这是logcat报告
