Permission denied when launching android SDK manager on ubuntu even with root authority

Question

I'm new to ubuntu, and want to develop android apps with eclipse (because I heard that the android studio can't work very well with NDK stuff yet).

First I installed java-8-oracle with apt-get, it was automatically installed under/usr/lib/jvm/java-8-oracle, then I set the environment variables, and executed java -version to test if is well installed, everything was fine I even wrote a HelloWorld in java using gedit and ran it in command line ,so there should be nothing wrong with the JDK I think.

But after I installed the eclipse and sdk (extracted frome adt-bundle-linux-x86_64-20140702.zip I download), when I opened the eclipse and tried to launch the SDK manager, the problem came like this (eguil is my username):

[2015-07-30 10:09:48 - SDK Manager] [SDK Manager] /home/eguil/android/sdk/tools/android: 1: /home/eguil/android/sdk/tools/android: /usr/lib/jvm/java-8-oracle: Permission denied
[2015-07-30 10:09:48 - SDK Manager] [SDK Manager] /home/eguil/android/sdk/tools/android: 1: /home/eguil/android/sdk/tools/android: /usr/lib/jvm/java-8-oracle: Permission denied
[2015-07-30 10:09:48 - SDK Manager] [SDK Manager] /home/eguil/android/sdk/tools/android: 110: exec: /usr/lib/jvm/java-8-oracle: Permission denied

Then I executed the command

sudo chmod -R 777 /home/eguil/android(where the eclipse and SDK are installed)

and

sudo chmod -R 777 /usr/lib/jvm/java-8-oracle

I assumed that I should never have any "permission problems" from now, but I was wrong, the problem still exists. I'v also tried launching the SDK manager in commond line sudo ./home/eguil/android/sdk/tools/android, but the output was the same.

Could anyone tell me the reason and how to solve the problem? I'll be appreciated, It's driving me crazy.

That isn't how you set the Java environment in ubuntu. Use

update-java-alternatives -s java-8-oracle

And you can list JVM(s) available with

update-java-alternatives -l
