java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “__aeabi_memcpy8” referenced by mylib.so

问题

When my app runs in Android 6.0 or below devices(Nexus 5, Galaxy 3...), it crashes at System.loadLibrary("mylib");

It works fine with Android 7.0 devices(Nexus 5x, Nexus 9). I use latest Android Studio(2.2) and NDK.

Log cat message is

java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "__aeabi_memcpy8" referenced by mylib.so.

Below is part of build.gradle.

compileSdkVersion 24
buildToolsVersion '24.0.2'
defaultConfig {
    applicationId "myApp"
    minSdkVersion 10
    targetSdkVersion 24 // Whatever this is, it crashes(22, 19...).
    ndk {
        moduleName "mylib"
    }
}

Below is Application.mk

APP_ABI := armeabi armeabi-v7a x86
APP_PLATFORM := android-10 // Whatever this is, it crashes.

What is the problem?

Even if I comment out all memcpy in .c files, it issues the same error message. Before I run, I clear and rebuild project.

回答1:

Make sure below your ndk>platforms hava the right paltform in your Application.mk APP_PLATFORM=Android-x.
