如何修复HelloCardboard示例的NDK构建错误 [英] How to fix NDK build error for HelloCardboard sample
问题描述
我正在尝试编译Google Cardboard Sdk示例.
我正在按照
这是我开始组装时遇到的错误:
FAILURE:构建失败，发生异常.* 什么地方出了错:任务':hellocardboard-android:externalNativeBuildDebug'的执行失败.>生成命令失败.执行过程C:\ Users \ Shanu \ AppData \ Local \ Android \ Sdk \ cmake \ 3.10.2.4988404 \ bin \ ninja.exe时出现错误，参数为{-CC:\ Projects \ cardboard \ hellocardboard-android \ .cxx \ cmake \调试\ x86board_jni}忍者:输入目录`C:\ Projects \ cardboard \ hellocardboard-android \ .cxx \ cmake \ debug \ x86'忍者:错误:'../../../../build/intermediates/cmake/debug所需的'../../../../libraries/jni/x86/libcardboard_api.so'/obj/x86/libcardboard_jni.so"，丢失，并且尚无已知规则* 尝试:使用--stacktrace选项运行以获取堆栈跟踪.使用--info或--debug选项运行，以获取更多日志输出.与--scan一起运行以获取完整的见解.*在https://help.gradle.org上获得更多帮助4秒内失败29项可执行的任务:2项已执行，27项最新下午1:55:12:任务执行完成了汇编". 然后我尝试使用-stacktrace
原因:org.gradle.internal.UncheckedException:构建命令失败. 但是还有一个警告:
警告:此应用程序仅具有32位[armeabi-v7a，x86]本机库.从2019年8月1日开始，Google Play商店要求所有包含本机库的应用程序都必须提供64位版本.有关更多信息，请访问https://g.co/64-bit-requirement 嗯，这让我不知道，因为以前从未使用过NDK/Cardboard SDK.
这是 build.gradle(hellocardboard)的外观:

- CMake
- LLDB
- NDK(并排)
这是什么问题，我该如何解决?
这通常在您尚未构建SDK时发生.
示例应用程序告诉您单击Gradle选项卡中的组装"选项.您应该单击:sdk"下的汇编"选项，而不是不是:hellocardboard-android"下的一个.
官方说明尚不清楚；仅当您仔细查看那里的屏幕截图时，它才可见.
I am trying to compile Google Cardboard Sdk sample.
I am following instructions given by google's official docs
I am stuck at step 3, where I am supposed to assemble the project:
This is the error I am getting when I start to assemble:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':hellocardboard-android:externalNativeBuildDebug'.
> Build command failed.

1:55:12 PM: Task execution finished 'assemble'.
Then I tried to run with --stacktrace
Caused by: org.gradle.internal.UncheckedException: Build command failed.
But there is an additional warning:
WARNING: This app only has 32-bit [armeabi-v7a,x86] native libraries. Beginning August 1, 2019 Google Play store requires that all apps that include native libraries must provide 64-bit versions. For more information, visit https://g.co/64-bit-requirement
Well, that doesn't give me an idea, as to have never used NDK/Cardboard SDK ever before.
Here is how the build.gradle(hellocardboard) looks like:
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
defaultConfig {
applicationId "com.google.cardboard.hellocardboard"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
ndk {
abiFilters 'armeabi-v7a', 'x86'
}
externalNativeBuild {
cmake {
cppFlags "-std=gnu++11"
arguments "-DANDROID_STL=c++_shared"
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
compileOptions {
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//noinspection GradleCompatible

//noinspection GradleCompatible
implementation 'com.android.support:design:28.0.0'
implementation project(":sdk")
}
// The dependencies for NDK builds live inside the .aar files so they need to
// be extracted before NDK targets can link against.
task extractNdk(type: Copy) {
if (file("${project.rootDir}/sdk/build/outputs/aar/sdk-release.aar").exists()) {
copy {
from zipTree("${project.rootDir}/sdk/build/outputs/aar/sdk-release.aar")
into "libraries/"
include "jni/**/libcardboard_api.so"
}
copy {
from "${project.rootDir}/sdk/include/cardboard.h"
into "libraries/"
}
}
}
task deleteNdk(type: Delete) {
delete "libraries/jni"
delete "libraries/cardboard.h"
}
build.dependsOn(extractNdk)
clean.dependsOn(deleteNdk)
Here is the whole project hosted on my GitHub
Everything is at google's default settings, and I haven't configured anything, except Install these components from the SDK manager:
- CMake
- LLDB
- NDK (Side by Side)
What is the issue here and how can I fix it?
This usually happens when you haven't built the SDK.
The sample app tells you to click the "assemble" option in the Gradle tab. You should click the "assemble" option under ":sdk", not the one under ":hellocardboard-android".
The official instructions are unclear about this; it is only visible if you look closely at the screenshots there.
