Я работаю над приложением Android, которое имеет встроенную зависимость от библиотеки, создаваемую с ndk-build. Библиотека, в свою очередь, зависит от встроенной статической библиотеки (.a), которую я добавляю в корень Android.mk, как показано ниже. Я намереваюсь выполнить сборку только для armeabi-v7a и arm64-v8a.
ifeq ($(TARGET_ARCH), arm)
LOCAL_SRC_FILES := lib/mylib_arm.a
else ifeq ($(TARGET_ARCH), arm64)
LOCAL_SRC_FILES := lib/mylib_arm64.a
else
$(error platform not supported!)
endif
. Когда я пытался построить проект, сборка завершилась неудачей в задаче :app:externalNativeBuildCleanDebug со следующей ошибкой.

Error while executing process /home/sourav/android/sdk/ndk/20.0.5594570/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/home/sourav/code/app/app/src/main/jni/Android.mk NDK_APPLICATION_MK=/home/sourav/code/app/app/src/main/jni/Application.mk APP_ABI=x86 NDK_ALL_ABIS=x86 NDK_DEBUG=1 APP_PLATFORM=android-21 NDK_OUT=/home/sourav/code/app/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=/home/sourav/code/app/app/build/intermediates/ndkBuild/debug/lib clean}

При дальнейшей проверке я обнаружил, что сборка вызывается следующим образом
/home/sourav/android/sdk/ndk/20.0.5594570/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/home/sourav/code/app/app/src/main/jni/Android.mk NDK_APPLICATION_MK=/home/sourav/code/app/app/src/main/jni/Application.mk APP_ABI=x86 NDK_ALL_ABIS=x86 NDK_DEBUG=1 APP_PLATFORM=android-21 NDK_OUT=/home/sourav/code/app/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=/home/sourav/code/app/app/build/intermediates/ndkBuild/debug/lib clean}
Очевидно, что Gradle не может правильно прочитать APP_ABI из Appilcation.mk. Я попытался установить abifilters во всех возможных местах, как вы можете видеть ниже.
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.example.app"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
externalNativeBuild {
// For ndk-build, instead use the ndkBuild block.
ndkBuild {
// Sets optional flags for the C++ compiler.
abiFilters "armeabi-v7a", "arm64-v8a"
}
}
ndk {
abiFilters "armeabi-v7a", "arm64-v8a"
}
}
buildTypes {
release {
ndk {
abiFilters "armeabi-v7a", "arm64-v8a"
}
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
debug {
ndk {
abiFilters "armeabi-v7a", "arm64-v8a"
}
}
}
externalNativeBuild {
ndkBuild {
path file('src/main/jni/Android.mk')
}
}
}
Несмотря на все мои усилия, сборка продолжает терпеть неудачу на одном шаге, и я вижу, что приложение все еще пытаетсяbuild для APP_ABI = x86, несмотря на четкие инструкции не делать этого.
Любая помощь будет принята с благодарностью! ТИА.
