我正在开发一个相当普通的资源使用应用程序（在Galaxy S3上大约19-22 MB，所以它绝对可以处理它），其中一个“功能”是显示联系人的信息，通过使用下一个代码：
public static Intent createIntentForContact(final String contactKey) {
final Intent intent = new Intent(Intent.ACTION_VIEW);
final Uri uri = Uri.withAppendedPath(Contacts.CONTENT_LOOKUP_URI, contactKey);
intent.setData(uri);
return intent;
}
...
startActivity(createIntentForContact(...)) ;
只要我留在应用程序上，一切正常。
但是，如果我在应用程序显示设备联系人信息时按住主页，然后返回应用程序，然后按回来，应用程序将自动重启。
我已经在一个全新的项目中测试了这个代码，但它在那里工作得非常好。我也在Galaxy S2上测试过它，它在那里工作得很好。我已经在设置中检查了开发人员类别，并且没有任何特殊内容。
怎么会发生这样的事情？ 该应用程序没有太多的内存，所以为什么它关闭，为什么它不与联系信息屏幕一起关闭（因为我没有添加任何标志）？
