我正在尝试获取一个在旧版 Android 手机上运行的应用程序，以在 Galaxy S20 FE 5G 上运行来自 adb logcat 的日志显示未找到“libiconv.so”

问题描述

我解压了 .apk 文件，文件 libiconv.so 位于正确的文件夹“/lib/aarch64/”中。

日志显示文件“未找到”。

这是日志的相关部分

I have read many fixes for this issue,they are available in great variety,but none seem applicable.  I have tried building at targetSdkVersion 28 and 21 to no avail.

Here is the build info from the device I am trying to run this on:
QUALCOMM build  7c6959d1f7,Ifdda647016
Build Date      09/03/20
Build Config    S P 10.0.5 AArch64
Driver Path     /vendor/lib64/egl/libGLESv2_adreno.so

I have some experience with this sort of work,last year I managed to ad a module to the app that required OpenCV,it was not fun but I got it to work. 

I am at a loss as to what to try next.

Thanks,Jim

解决方法

我发现了一个很好的页面，帮助很大。

https://github.com/pelya/libiconv-libicu-android/

我将 GNU libiconv tar 文件从 15 更新为 16，并为 arm64-v8a 构建了 libiconv.so

现在我需要 libc++ 库。
