Which JDK version Language Level is required for Android Studio

Question

I am a new comer to the android world and with a  NET background  I am trying to install the Android Studio but I am having a mismatch on Android com about the JDK version required for developing Android applications   From the SDK web page it states that JDK 6 is required  under system requirements section   Jim Wilson also insist in his course on Pluralsight  which is quite new  from last May  that using version 7 with the Android SDK will create a lot of headache and makes it clear to only use JDK 6    Although in the Android studio page  Under installing step 2  they explain how to set an environment variable indicating the correct JDK location  In here they use a path of JDK 7     Select Start menu  gt  Computer  gt  System Properties  gt  Advanced System Properties  Then open Advanced tab  gt  Environment Variables and add a new system variable JAVA HOME that points to your JDK folder  for example C  Program Files Java jdk1 7 0 21    I am pretty sure both the ADT  amp  Eclipse bundle and the Android Studio bundle are using the same SDK but now I am confused about which JDK version I need to install  My sole purpose is to avoid problems as much as possible while getting my first steps into the Android development   Disclaimer  I am not related by any mean to Pluralsight  I am just a normal user following the courses

Try not to use JDK versions higher than the ones supported  I ve actually ran into a very ambiguous problem a few months ago   I had a jar library of my own that I compiled with JDK 8  and I was using it in my assignment  It was giving me some kind of preDexDebug error every time I tried running it  Eventually after hours of trying to decipher the error logs I finally had an idea of what was wrong  I checked the system requirements  changed compilers from 8 to 7  and it worked  Looks like putting my jar into a library cost me a few hours rather than save it

Normally  I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6  I d use JDK 6 because you would want your development environment to be as close as possible to the instructors  It would suck if you ran into an issue and having the thought in the back of your head that maybe it s because you re on JDK 7 that you re having the issue  Btw  I haven t touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you  I only code Android apps casually

Answer Clarification - Android Studio supports JDK8  The following is an answer to the question  What version of Java does Android support   which is different from  What version of Java can I use to run Android Studio   which is I believe what was actually being asked  For those looking to answer the 2nd question  you might find Using Android Studio with Java 1 7 helpful    Also  See http   developer android com sdk index html latest for Android Studio system requirements  JDK8 is actually a requirement for PC and linux  as of 5 14 16      Java 8 update  3 19 14   Because I d assume this question will start popping up soon with the release yesterday  As of right now  there s no set date for when Android will support Java 8   Here s a discussion over at  androiddev - http   www reddit com r androiddev comments 22mh0r does android have any plans for java 8   If you really want lambda support  you can checkout Retrolambda - https   github com evant gradle-retrolambda  I ve never used it  but it seems fairly promising   Another Update  Android added Java 7 support  Android now supports Java 7  minus try-with-resource feature   You can read more about the Java 7 features here  https   stackoverflow com a 13550632 413254  If you re using gradle  you can add the following in your build gradle   android       compileOptions           sourceCompatibility JavaVersion VERSION 1 7         targetCompatibility JavaVersion VERSION 1 7             Older response  I m using Java 7 with Android Studio without any problems  OS X - 10 8 4   You need to make sure you drop the project language level down to 6 0 though  See the screenshot below     What tehawtness said below makes sense  too  If they re suggesting JDK 6  it makes sense to just go with JDK 6  Either way will be fine       Update  See this SO post -- https   stackoverflow com a 9567402 413254
