Issue
I'm having trouble debugging C++ files of my library module.
Is this possible in general?
The debugging works fine if the application project contains the c++ code. But I want to move the C++ Code to a library module.
The Error Message while starting the session:
Now Launching Native Debug Session
Attention! No symbol directories found - please check your native debug configuration
gradle file of my lib:
apply plugin: 'com.android.library'
android {
compileSdkVersion 24
buildToolsVersion "25.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 21
versionCode 1
versionName "1.0"
externalNativeBuild {
cmake {
arguments "-DANDROID_PLATFORM_LEVEL=${11}",
'-DANDROID_TOOLCHAIN=clang', '-DANDROID_STL=gnustl_static'
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-annotations:24.2.0'
}
In the run configuration the debugger is set to auto
Additions:
Im using:
Gradle : 2.2.3
Android Studio : 2.2.3
in the LLLB Console, i checked the breakpoint List with:
breakpoint list -v
all my checkpoints are listed there.
Not Working Breakpoint
1: file = 'C:\android-dev\...\test.cpp', line = 19, exact_match = 0
..thats all
Working Breakpoint

location = C:\android-dev\...\test.cpp:16

resolved = true
hit count = 1
Solution
The reason seems to be, that a release version of the lib is created, which does not support debugging, even if the app is built with debug options.
Solution:
To solve this issue, do the following workaround. It ensures that a debug version is built.
In your apps build.gradle change:
compile project(':nativelib')
to
compile project(path: ':nativelib' , configuration: 'debug')
In the libs build.gradle add:
android {
publishNonDefault true //this line
compileSdkVersion 24
buildToolsVersion "25.0.2"
defaultConfig {
...
}
...
}
