Android NFC restart App -


I use NFC to send a text app to my app on the device app on my app Device Nr.2 Then the device is in touch, both device popups "Touch the beam" UI. If I send touchscreen and beam messages NR.1 (by adding OT to the part) on the device - message sent, it's okay to do everything. But if I get the device number Touch 2 "touch the ray" UI (the message should be received) - Then my app NR on the device 1 has been reloaded The log code is not showing anything wrong, no error seems, this case app gets any kind of empty NFC message? But why does not it do anything on it? Why reload? I am using foreground despatches , I can make "program / text" without any manifest.

How can I control this situation, so users "touch the beam" "UI"?

If you do not set the Android beam in your app, then default behavior on the beam of Android is either Instructions have to be directed to another device to open the same app (first activity, which filters the menu / launcher intents of the same package name app on the source device as an app) or if your app is not installed Open Play Store Store listing it on an AAR (+ play store Link?) Is sent.

In your case, clicking on the Beam UI on Device 2, AAR is shipped to Device 1. As a result, your app will be opened on the device (again) 1. To overcome this, you can:

  1. Enable foreground transmissions for activity on device 1, so that The NDEF message can be received promptly processed by your app. I'm not sure that this beam collides with the UI.
  2. Change the NDEF message sent by Device 2 to not include an AAR using the Beam API.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
