Android requires compiler compliance level 5.0 or 6.0. Found ' 1.7 ' instead. Use Android Tool

Re-configure the Android development environment after reinstalling the operating system. After a successful configuration, an error occurred while adding the original project!

Android requires compiler compliance level 5.0 or 6.0. Found ' 1.7 ' instead. Please use Android Tools > Fix Project Properties.

Workaround:

1. Project Right-click->android tools->fix Project

2. If not, check the Project->properties->java compiler to confirm that the JDK compliance is set to 1.6 and enable specific seetings, which is basically resolved after the two-step problem.

Another eeror, after updating the Android SDK, will often encounter an "SDK manager:failed to Install" "tools can ' t write" and the like that the tools file cannot write errors.

If the installation process prompts "SDK manager:failed to install", do not hurry, first exit, and then

1. Go to the Temp folder of the SDK, there will be a download good tools_r06-windows.zip (the name may be a little different)

2. Unzip the file and the Tools_r06-windows folder appears

3. Enter, copy all files in tools_r06-windows directly and overwrite the files in the Tools folder of the SDK root directory
