First try making sure your target and minimum APIs are correct in project settings. Then try enabling Support OpenGL ES2 in your project settings. Next thing you can try is editing your android build settings to support different builds, such as armv7, arm64, etc. If you enable armv7 and arm64, for example, packaging the project will give you two SDKs for each build type.
Next thing I recommend is packaging your project as ETC1.
If none of those things worked:
Uninstall everything codeworks 1R6u1 installed, and install codeworks 1R7u1 instead. Unless of course you are using an older version of the engine which uses an older version of codeworks. 1R7u1 should work fine and bring all the SDKs you need. After 1R7u1 installs everything, make sure the environment variables (if on windows) on your computer are correct. Then in your project settings, ensure that you set the correct target API and minimum API. Android 5.0 is API 21, so your minimum can be 21 and your target can be 25 for android 7.1.
