Android Studio 2.2 原生开发迁移问题 [英] Android Studio 2.2 Native Development Migration Issue

问题描述

在切换到 AS 2.2 之前，我有以下结构来实现我的 C

Before making the switch to AS 2.2, I have the following structure to implement my C

app/src/main/jni/Android.mk
app/src/main/jni/Application.mk
app/src/main/jni/headers/*
app/src/main/jni/cfiles*.cc

在这种情况下，一切都很好.但是，升级到 AS 2.2 后，我无法构建任何 apk 并且总是收到以下错误:

in which case everything built fine. However, after upgrading to AS 2.2, I cannot build any apk and always recieve the following error:

任务执行失败':app:transformNative_libsWithStripDebugSymbolForDebugjava.lang.NullPointerException(无错误提示)

有谁知道这是为什么?我似乎无法找到解决方法.

Does anyone know why this is? I cannot seem to find a work around.

推荐答案

我觉得很多这些解决方案都有些过头了.很抱歉回答我自己的问题，但实际的解决方案几乎来自这里的每个帖子！

I felt like a lot of these solutions were overkill. Sorry for answering my own question, but the actual solution was taken from just about every post here!

很像@GregT 所说的，对我有用的是升级我安装的 NDK 包.而且，这样做实际上修改了 *.mk 文件，就像@Matthew_Bondarchuk 的回答一样.

Much like what @GregT said, what worked for me was upgrading the NDK package that I had installed. And, doing so actually modified the *.mk files, much like @Matthew_Bondarchuk's answer.

因此，就像@aaronvargas 所说的，这是一个错误；具体来说，Android NDK 系统没有与 Android Studio 2.2 实例化的升级一起更新.这会导致与 Android 构建工具不兼容，就像@Michael_Jess 所说的那样.

Consequently, like @aaronvargas said, this is a bug; specifically, the Android NDK system was not updated in conjunction with the upgrades that Android Studio 2.2 instanced. This causes an incompatibility with the Android build tools, much like @Michael_Jess said.
