Everything compiled well and my apk is built, but at runtime I get this error:
java.lang.UnsatisfiedLinkError: dlopen failed: library "../../../../libs/x86/mylib.so" not found
I tried to extract the apk and check libs/x86 folder and the .so is there.
My android field at app/build.gradle is:
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.example.test"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags ""
}
}
ndk {
abiFilters "x86"
}
}
buildTypes {

minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}

remove code like this from your gradle

abi {
enable true
reset()
// Specifies a list of ABIs that Gradle should create APKs for.
include "x86", "x86_64", "armeabi-v7a", "arm64-v8a", "armeabi", "mips", "mips64"
universalApk true //generate an additional APK that contains all the ABIs
}
}
Please someone help me, I'm stuck here.

This is my error and I don't know what to do.
Could not find method path() for arguments [C:\Users\costy\AndroidStudioProjects\android\app/jni/Android.mk] on object of type com.android.build.gradle.internal.dsl.ExternalNativeNdkBuildOptions.
I'm trying to export a .apk file and I was stuck with the Deprecated NDK problem. Now I'm stuck with this problem.
The externalNativeBuild block that specifies the makefile path should not be part of defaultConfig, but of its android parent:
android {
compileSdkVersion 26
// etc...
defaultConfig {
applicationId "com.glitchrun.sapphire"
// etc...
externalNativeBuild {
ndkBuild {
arguments "NDK_APPLICATION_MK:=$projectDir/jni/Application.mk"
abiFilters "armeabi-v7a", "armeabi", "arm64-v8a", "x86"
cppFlags "-frtti -fexceptions"
}
}
}
// etc...
externalNativeBuild {
ndkBuild {
path "$projectDir/jni/Android.mk"
}
}
}
The inner one is used to modify ExternalNativeBuildNdkOptions, while the outer one is used to modify NdkBuildOptions.
Recently i have tried to attach cmake with my existing android studio project. I am searching SO since last four day not yet succeeded. Please don't mark this as duplicate. I am running android studio 2.2.1 with gradle version 2.14.1 in windows 8.1pro.
My build.gradle (app level):
apply plugin: 'com.android.application'

}

I am getting this error in message view:
Error while executing 'C:\Users\User\AppData\Local\Android\Sdk\cmake\3.6.4111459\bin\cmake.exe' with arguments {-HF:\MyProject\app\src\main\cpp -BF:\MyProject\app\.externalNativeBuild\cmake\x86_64Debug\x86_64 -GAndroid Gradle - Ninja -DANDROID_ABI=x86_64 -DANDROID_NDK=C:\Users\User\AppData\Local\Android\Sdk\ndk-bundle -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=F:\MyProject\app\build\intermediates\cmake\x86_64\debug\obj\x86_64 -DCMAKE_BUILD_TYPE=Debug -DCMAKE_MAKE_PROGRAM=C:\Users\User\AppData\Local\Android\Sdk\cmake\3.6.4111459\bin\ninja.exe -DCMAKE_TOOLCHAIN_FILE=C:\Users\User\AppData\Local\Android\Sdk\ndk-bundle\build\cmake\android.toolchain.cmake -DANDROID_NATIVE_API_LEVEL=21 -DANDROID_TOOLCHAIN=clang}
I don't know what's wrong here.
I am trying to generate a static library using CMAKE and Android Studio(2.3.2). Below is what my CMakeLists.txt looks like. I am unable to generate .a file, however when I change the library to SHARED, CMakeTestModule.so file gets generated when I do "Build->Rebuild Project". Is it required for me to add/set any flag for building STATIC libraries.
cmake_minimum_required(VERSION 3.4.1)
project (CMakeTestProject)
include_directories(
src/main/cpp/
)
add_library(
CMakeTestModule
STATIC
src/main/cpp/CMakeTestModule.cpp
)
add_executable(
CMakeTestModule_test
src/main/cpp/CMakeTestModule_test.cpp
)
target_link_libraries(CMakeTestModule_test CMakeTestModule)
This is what my build.gradle looks like:
apply plugin: 'com.android.library'
android {
compileSdkVersion 16
buildToolsVersion "25.0.0"
defaultConfig {
minSdkVersion 8
targetSdkVersion 8
externalNativeBuild {
cmake {
abiFilters 'armeabi'
}
}
}
externalNativeBuild {
cmake {
path 'CMakeLists.txt'
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
I fixed this issue by specifying the target in the build.gradle. Something like below. Since apk only uses .so files, we need to mention the targets for static libraries and executables.
apply plugin: 'com.android.library'
android {
compileSdkVersion 16
buildToolsVersion "25.0.0"
defaultConfig {
minSdkVersion 8
targetSdkVersion 8
externalNativeBuild {
cmake {
abiFilters 'armeabi'
}
targets "CMakeTestModule_test", "CMakeTestModule"
}
}
externalNativeBuild {
cmake {
path 'CMakeLists.txt'
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
If I have a build.gradle for an application:
android {
compileSdkVersion 24
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.ndkcmaketest.headwayent.ndkcmaketest"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags "-frtti -fexceptions"
arguments "-DANDROID_ARM_NEON=TRUE", "-DANDROID_TOOLCHAIN=gcc"//, "-DANDROID_ALLOW_UNDEFINED_SYMBOLS=TRUE"
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
}
How do I add cpufeatures as ldlibs? Adding ldLibs.addAll(["cpufeatures"]) in externalNativeBuild does not work. And neither adding in an ndk block.
Do you have to add this to build.gradle specifically? If not, add the following to one of your CMakeLists.txt files:
include(AndroidNdkModules)
android_ndk_import_module_cpufeatures()
Then you can target_link_libraries(<your target>, cpufeatures).
That macro and a couple of others are defined in $ANDROID_SDK/cmake/<cmake-version>/share/cmake-<version>/Modules/AndroidNdkModules.cmake.
