Add .so files to Cordova Plugin

Question

I have developed a Cordova Plugin for my Ionic app, which throws the following error when accessed:

java.lang.UnstatisfiedLinkError: dalvik.system.PathClassLoader [DexPathList [[zip file "/data/app/io.ionic.starter-2/base.apk"], nativeLibraryDirectories=[/data/app/io.ionic.starter-2/lib/arm/, /vendor/lib, /system/lib]]] couldn't find "libserial_port.so"

I've put libserial_port.so file in the libs folder, at this path: pluginName\src\android\libs\armeabi\libserial_port.so.

Then, in plugin.xml I've tried to load it both as a resource file:

<resource-file src="src/android/libs/armeabi/libserial_port.so" target="src/android/libs"/>

and as a lib-file:

<lib-file src="src/android/libs/armeabi/libserial_port.so" />

However, the error still appears. What shall I do for the app to see that library?

I am also facing same issue after using Cordova 8 (Cordova-Android 7).Were you able to resolve it ? — manjunath kallannavar, Feb 19 '18 at 04:54
@manjunathkallannavar I'm facing the issue too. Did you able resolve or workaround the issue? — micksatana, Jul 17 '18 at 14:03
I am able to resolve the issue .Add .so files in both jniLibs and lib and delete either of them based on your cordova version — manjunath kallannavar, Jul 17 '18 at 14:06

I am able to resolve this issue by renaming libs to jniLibs.

Change

<resource-file src="src/android/libs/armeabi/libserial_port.so" target="libs/armeabi/libserial_port.so">

to

<resource-file src="src/android/libs/armeabi/libserial_port.so" target="jniLibs/armeabi/libserial_port.so">
