android 在另一个应用程序上共享内容时显示错误

Question

Android 在将数据共享到另一个应用程序时在 android nougat 中运行应用程序时显示致命异常。它在牛轧糖下面完美运行。

这是我的代码

  Intent sendIntent = new Intent(Intent.ACTION_SEND);
  sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Student Details of " + currentDate);
  sendIntent.putExtra(Intent.EXTRA_STREAM, u1);
  sendIntent.setType("text/plain");
  startActivity(sendIntent);  // Gives error on this line

这是错误显示。

Answer 1

试试这个

startActivity(Intent.createChooser(shareIntent, 
getResources().getText(R.string.send_to)));

代替

startActivity(sendIntent);
