I'm trying to use java version 1.7 with android studio but unfortunately it is not working properly...
If set the version in File->Other settings -> Default project structure to
Project SDK:
java version 1.7.0_06
Project language level:
7.0 Diamonds, ARM, multi-catch
But when I use a switch-statement with a string I get an error which should be possible in java 1.7, so do I need to set any other settings?
No... there is no settings to change. Android SDK don't support full java 7 syntax, so you can't use it.
Note that java.nio.* (new in java 7 API) is supported by latest android version.
You can change it in new Android studio version(0.8.X)
FIle-> Other Settings -> Default Settings -> Compiler (Expand it by clicking left arrow) -> Java Compiler -> You can change the Project bytecode version here
You can change jdk version from File > Other settings > Default Project structure. Then JDK location:

The external libraries in Project window shows that the project was using jdk7.
Then I change the jdk version in File > Other settings > Default project structure> SDKs, by adding jdk 8 from its installed location. Now java 7 is gone, but java 8 does not show up and it could not compile. Is this a bug or did I miss anything?
if I add java 7 then it comes back in External Libraries:
You also have to adjust dependencies in module itself / remove old 1.7 libraries and add from new sdk
change the module settings indeed. Right click on the module (which I understand it as project in Eclipse I guess) and click Open module settings (F4 shortcut), and on tab dependencies, change it to 1.8, originally it was blank. (If it was blank shouldn't it be using the project settings which is already configured as java 8, but no, for some reason it still use java 7)
I am working on an existing Java web project. I am getting lots of syntax errors in the files. It shows it needs JDK version 1.5. I have Eclipse Luna (4.4.1), which doesn't support JDK 1.5. How can I find out which version of Eclipse is compatible with JDK 1.5?
You can go to Preferences -> Java -> Installed JRE and add a new java VM which is Java 1.5.
Also, for your project, go to Project's properties -> java compiler. Check the checkbox to enable project specific setting and set the compliance level to java 1.5
I am having a problem with Eclipse Luna after an update. Despite showing in the tree for the project that it is using JRE system library 1.7 the error checking is reporting bugs with a switch using a string that it has a source level below 1.7.
The specific error:
Cannot switch on a value of type String for source level below 1.7. Only convertible int values or enum variables are permitted
I have tried going into Properties > Build Path and adding and removing the library but this has not fixed the problem.
I moved from the Eclipse packaged with Debain Wheezy which uses the 1.6 JDK and the much older Eclipse 3.8. I am now using CentOS 7 with the 1.7 JDK. The migration has not been as smooth as I hoped. Since there has some big version jumps, I need help getting this new 4.4 version working properly.
Window -> Preferences -> Java Compiler -> set the compiler level to 1.7
Same for Project -> Properties -> Java Compiler -> 1.7
If you can't find that option (by which I mean Compiler 1.7), you must specify the Installed JRE to be JDK 7 too.
Hi I am working on an android project that requires File searching.
Now theres one problem that has arised -> I cannot import the package java.nio.file.*;
whatsoever even when I have installed jdk 7. Am using eclipse for android.
Plz help
Earlier I have changed Window>preferences>java>compile>1.7
The project compiles.
But when I changed Project>properties>java compiler>1.7
Then it gives me the following error
"Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties."
Android does not currently support Java 7.
The system requirements for the Android SDK currently specify Java 6.
The current android specifications require your project to be compiled under java 5 or java 6. Like Jason C has said, java 7 is not currently supported.
Unfortunately there isn't much way to bypass this restriction (if you intend to publish your application) so your stuck with rewriting any java 7 code (empty <> operation, try-with-resources, etc) into java 6.
Android Systems only support java versions upto Java 6 and hence the builder is complaining for it. In builder you can create different kind of projects(non-android also), hence it allows to set the java compiler preferences to version 1.7 in windows menu. But if you try to set the java compiler version to 1.7 for an android project, it will not let you.
Android SDK is not x64. So it will not support java7. It will check for any compatible version like java5.java6. So choose java6. That's why you've got this problem. Try Fix Project Properties, if still getting error change version 1.7 to 1.6 from project > properties > java compiler > 1.6!
Can any one tell me what shall I do when Eclipse shows this message:
[2012-02-28 10:57:34 - LMP] Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.
Actually it was shown when I took a project from anther laptop then I added it to my workspace then I imported it to my eclipse.
Looks like you're using java 1.7 when 1.6 or 1.5 required.
Project > Properties > Java Compiler
Set compiler compliance level to 1.5 or 1.6.
You are using Java 7 on your project, but the VM on Android only supports Java 5~6.
Just have to configure eclipse to use Java 6 compliance level (:
