在开发者M preVIEW共享库 [英] Shared Libraries in Developer M Preview

问题描述

我想测试一下我的版本的Andr​​oid M开发preVIEW应用。

I am trying to test out my application on the Android M dev preview.

我的应用程序使用共享库，我已经放在JNI /库/ armeabi的Andr​​oid Studio中。我相信，当它调用的System.loadLibrary（MYLIB）这是扔以下的UnsatisfiedLinkError。是其他任何人有这个问题？ Android的5.x的没有问题与此有关。

My application is using a Shared library, which I have placed in jni/libs/armeabi inside of Android Studio. I believe when it calls System.loadLibrary("myLib") it is throwing the following UnsatisfiedLinkError. Is anyone else having this issue? Android 5.x has no problem with this.

更新：

我收到关于这个问题的一些意见。在我的Andr​​oid.mk文件我该线下方，目前的信念是，这条道路是不正确的，它是没有找到，因为它的文件。

I have received some feedback on the issue. In my Android.mk file I have the line below, currently the belief is that this path is not correct and that it is not finding the file because of it.

LOCAL_SRC_FILES    := libs/$(TARGET_ARCH_ABI)/myLib.so

推荐答案

我解决我的问题，以确保库我的prebuild过的soname集。请参阅以下的Andr​​oid开发者preVIEW问题线程

I solved my problem, by making sure my prebuild of the library had a soname set. See the following Android Developer Preview issue thread

https：//开头code.google.com / p / Android的开发技术preVIEW /问题/细节？ID = 2239

项的10号左右我的prebuilt需要有SONAME集，我previously早已不是线程会谈。

item number 10 in the thread talks about my prebuilt needing to have the soname set, which I previously had not.

所以在我的库构建脚本我加了轮候册，-soname，LIB {} mylibname。所以我LDFLAGS变量

so in my library build script I added -Wl,-soname,lib{mylibname}.so to my LDFLAGS variable

export LDFLAGS="--sysroot ${TOOL_PREFIX}/sysroot -L${PREFIX}/lib -L${TOOL_PREFIX}/lib ${LDFLAGS_EXTRA} -Wl,-soname,libmylib1.0.so"
