Nothing that several Android IDEs will be installed on the computer? No need to set environment variables in computer settings?

Question

IDE

By chance, the SDK will not start downloading the necessary components to another folder?

Answer 1

It seems that in any ide you can drive your paths to the android sdk.
It will be enough to install one copy.

Answer 2

Only Android Studio takes and downloads the SDK if you ask it to, of course. Otherwise, ANDROID_HOME is used or the dira is set by handles.
You do not have a question: if I install Eclipse && Netbeans, I can develop under Java ???

Answer 3

if (!localStorage.getItem('item')) {
  alert('В следующий раз этого окна не будет');
  localStorage.setItem('item', true);
}
