Unity exports Android encounters a build target error

1. The export runs after the build target = "9", version is wrong, can ' t loaded xxx.untiy3d files and the like, generally look at the exported jar inside the project.properties target Correct, correct and clean related items.

2. See if Androidmanifest.xml android:minsdkversion and android:targetsdkversion are correct and refresh after correction

3. Does reading the wrong message prompt you to use Android tools to fix project properties, if any, please do

4. This is the problem I encountered, because Untiy's Android SDK and eclipse different, so caused the error, please use the same Android SDK, the operation is as follows:

In eclipse, open preference with window and select SDK location under Android

Untiy Select Edit under Preferences in the Android SDK location of external tools
