Android Error – Higher Compiler Compliance Level Required

You will see the following error:

Android requires compiler compliance level X or Y. Found 'Z' instead. Please use Android Tools > Fix Project Properties.

There are several ways to fix this problem. We try the first one, and if it doesn’t work, we try the next one.

Solution 1

Right-click the file that shows the error and select “Android Tools / Fix Project Properties”.

Check whether the problem has been fixed. If not, move on to the next step.

Solution 2

Go to the project, then choose a class that has the problem. Go to a line with the error and hover the pointer over it; the possible fixes you can try will appear.

Try the different auto-fix options that Eclipse offers. Check whether the problem has been fixed. If not, move on to the next step.

Solution 3

If, for example, you get errors on @Overrides and other annotations from other compliance levels, try changing the compiler version. To do this, right-click the project that gives you trouble and select “Properties”.

Then, in the “Java Compiler” tab, select “Enable Project specific settings” and change the version under “Compiler compliance level:” (the highest number, which will be the newest, is recommended). Apply the changes and click yes on the message that appears.

The problem should now be fixed.
