Why would Android Studio 1.0 rc start downloading Android SDK without detecting if there existing one?

I've installed Android Studio 1.0 rc and Android SDK in my
Archlinux box. But when I try to create a new Android Application, the
AS would try to download another set of SDK directly from
dl-ssl.google.com. I mean why, why wouldn't it start first and let me
configure the SDK path? (I am in mainland China, so the connect will
be reset all the times, in another word, AS will not start to
workspace.

I have an action bar method for my app for almost 1 year. Now i
updated my SDK and Android studio version, and it crashes. Here is the
code:

public void initializeActionBar() {

    ActionBar actionBar = getActionBar();



    actionBar.setBackgroundDrawable(new ColorDrawable(0xff50aaf1));



    getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

   

getActionBar().setCustomView(com.entu.bocterapp.R.layout.action_bar_center_image);

}

Can you help me to get what is wrong?

Cheers!

Today Only I downloaded latest Android Studio(for the 1st time),
it got installed properly but when I open it it gets stuck at
"downloading Android Studio SDK build-tools, revision 21.1.1"
I closed it reopened it still gets stuck at same place.
I uninstalled it, re installed it but nothing happens same problem
comes.
P.S. this comes when I open Android Studio Icon.
I have not opened and downloaded it manually.

While installing Android Studio I got the following error at the
time of initializing. And could not override with the given option
(not accepting input).

Error : "Failed to rename directory C:AndroidSDK ools to
C:AndroidSDK empToolPackage.old01."

I gave installation path to C drive for both Android SDK and
Studio.

Any Suggestions?

Solution:

Open Android Studio as "Run as administrator"

I'm getting "Error: Android Source Generator:[app_name] Android SDK
is not specifed" in Android Studio while trying to Build Project.

I have Android Studio 1.0.2 RC4 version.

What have been done:

• SDK installed ith SDK Manager


• Project Structure -> SDK; I have added there minimum and target
  SDK as well


• updated build.gradle

Say I have copied my source code of Android Studio project to a
machine where neither Android Studio is installed nor Android SDK. I
just have Gradle installed and I want to build project via command
prompt. I'm familiar that SDK is mentioned as requirement on official
Android website, but is there any work around? I just want to make
build, nothing more.
