How to use MuPDF with your EXISTING Eclipse project:

1. Copy the 'jni' folder from the <mupdf>/android folder into your existing Eclipse project.
2. Copy the <mupdf>/thirdparty folder into the 'jni' folder in your project.
3. Copy the <mupdf>/cbz folder into the 'jni' folder in your project.
4. Copy the <mupdf>/draw folder into the 'jni' folder in your project.
5. Copy the <mupdf>/fitz folder into the 'jni' folder in your project.

8. Copy the <mupdf>/xps folder into the 'jni' folder in your project.

MUPDF_ROOT := $(TOP_LOCAL_PATH)

11. Save 'Android.mk'.
12. Open 'Core.mk' inside the 'jni' folder.
13. Change

MY_ROOT := ../..

to

MY_ROOT := $(LOCAL_PATH)


14. Change all the

..

in LOCAL_C_INCLUDES to

$(LOCAL_PATH)

14. Save 'Core.mk'.
15. Open 'ThirdParty.mk' inside the 'jni' folder.
16. Change

MY_ROOT := ../..

to

MY_ROOT := $(LOCAL_PATH)

17. Change all the

..

in LOCAL_C_INCLUDES to

$(LOCAL_PATH)

18. Save 'ThirdParty.mk'.
22. Now execute 'ndk-build' in your project's 'jni' directory.
23. Copy everything in the <mupdf>/android/src folder into the 'src' folder in your project.
24. Copy everything in the <mupdf>/android/res/drawable folder into the 'res/drawable' folder in your project.
25. Copy everything in the <mupdf>/android/res/drawable-ldpi folder into the 'res/drawable-ldpi' folder in your project.
26. Copy everything in the <mupdf>/android/res/drawable-mdpi folder into the 'res/drawable-mdpi' folder in your project.
27. Copy everything in the <mupdf>/android/res/layout folder EXCEPT main.xml (because if you are copying into an existing project then you should already have your own main.xml or equivalent) into the 'res/layout' folder in your project.
28. Copy everything in the <mupdf>/android/res/values folder into the 'res/values' folder in your project. If you already have a 'strings.xml' in your existing project, copy everything in between the '<resources>' tags in your <mupdf>/android/res/values/strings.xml into your project's strings.xml (paste between the '<resources>' tags). Similarly with the 'colors.xml',  if you already have a 'colors.xml' in your existing project, copy everything in between the '<resources>' tags in your <mupdf>/android/res/values/strings.xml into your project's strings.xml (paste between the '<resources>' tags).
29. Open the 'AndroidManifest.xml' in project.
