ImageDecoder

[khalil torabi]

Hi,

Coult you plz help me what is the problem?

I am trying to work with The NDK ImageDecoder API  with bellow settings:

build gradle:

android {
compileSdkVersion 30
buildToolsVersion '30.0.2'
defaultConfig {
minSdkVersion 26
targetSdkVersion 30
versionCode 1
versionName '1.0'
externalNativeBuild {
cmake {
arguments '-DANDROID_STL=c++_static'
cppFlags "-std=c++11"
}
}
ndk {
abiFilters "x86_64", "x86", "armeabi-v7a", "arm64-v8a"
}
}

CmakeLists.txt:

find_library( #
image-lib
jnigraphics )

target_link_libraries( myapp
${image-lib}
)

and also tested:

target_link_libraries( myapp
jnigraphics
)

the result is:

Build command failed.
