不满意的linkerror aarch64三星银河S6

Question

Hi I have been trying to test my code on my Samsung Galaxy S6, but it keeps crashing because of an Unsatisfied linkerror. Here is the error message:

I am using jna.jar as a library and I believe that's where the problem is stemming from. When I go into the folders, there is no folder named android-aarch64 and I am not sure how to get it.

Here are the folders in jna.jar: Screenshot

Answer 1

it mostly happens when you use native library and there isn't support in Android Gradle for native code yet for native libraries try this

1. make a folder name "jniLibs "
2. add these sub folders one by one
   • armeabi
   • armeabi-v7a
   • mips
   • x86

put your library into these folders and rebuild your project

Hope this will help

Answer 2

Not entirely sure you need a JAR file.

In the Emotiv Android examples , there is this Gradle dependency.

compile 'com.emotiv.sdk:community:3.3.+@aar'
