Where to get ebookdroid lib about ebookdroid

[clockwiser]

Inside ebookdroid-legacy-1.5.7-dev-r1908.apk, there is a lib libebookdroid.so.

[clockwiser]

Actually it is located in the folder, ebookdroid/app/src/main/jniLibs/armeabi.
But System.loadLibrary("ebookdroid") fails.

[clockwiser]

Must run with the armeabi emulator, but there is no armeabi images in android studio 3.1.4. At last, create the library again for armeabi-v7a using android ntk. The intermediate folder holds libraries created for different versions of emulators. The folder is described in iml file as "output url" tag.

Also create an x86 lib using ndk.

1. Add x86 to Application.mk in bookdroid/app/src/main/jni.

---

APP_ABI := armeabi armeabi-v7a x86

APP_CFLAGS := -DHAVE_CONFIG_H -DTHREADMODEL=POSIXTHREADS -DDEBUGLVL=0 -D__ANDROID__
APP_CFLAGS += -O3

APP_MODULES := jpeg libdjvu mupdf ebookdroid hqx

---

2. Run ndk build in the folder bookdroid/app/src/main/jni.
   ebookdroid/app/src/main/jni$ ~/Android/android-ndk-r9d/ndk-build

3. Check log if x86 lib created.
   [x86] Compile : ebookdroid <= jni_concurrent.c
   [x86] Compile : hqx <= hq4x.c
   [x86] Compile : hqx <= hq2x.c
   [x86] Compile : hqx <= hq3x.c
   [x86] StaticLibrary : libhqx.a
   [x86] StaticLibrary : libstdc++.a
   [x86] SharedLibrary : libebookdroid.so
   [x86] Install : libebookdroid.so => libs/x86/libebookdroid.so

4. Copy x86 lib from libs to ebookdroid/app/build/intermediates/jniLibs/debug.
   There must be an x86 folder under debug, where the lib locates.

5. Run with AVD Galaxy Nexus api 10 (Android 4.0.3).

6. Set cool booting, don't use snapshot booting.

7. Upload file to mnt/asec using Device file explorer in Android studio.

Then start playing with ebookdroid.
