I'm trying to add native code to my Android app. NDK worked fine with simple C++ code like "Hello from C++", but I need to use openCV, and I am stuck.

Thanks for any help.
I've tested your project. To make it build successfully, I had to delete the folder app/src/main/jni and the folder app/src/main/3rdparty and the file opencvlibrary-2.4.9.jar in the folder app/libs/. It looks like you have several opencv libs (thus conflicting with each others) in your project.
Hope this helps.
Have you tried to build your project with Eclipse ? I worked a little with OpenCV on Intellij and had some trouble to make it work, it was also a problem of NDK.
The current NDK support in Android Studio and the Android gradle plugin 1.1.0 is limited and deprecated. Auto-generated Makefiles are used on the fly, and linking an external NDK library (like OpenCV) from your NDK sources isn't supported out-of-the-box.
You should remove your ndk{} block inside build.gradle and deactivate the current NDK integration, in order to rely directly on ndk-build and your Makefiles instead. You can also use splits instead of flavors to generate per-ABI APKs, like in this gist: https://gist.github.com/ph0b/9e59058ac59cac104398
Your build.gradle would be like this:
import org.apache.tools.ant.taskdefs.condition.Os
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.gogiant.opencvfeaturedetection"

}
splits {
abi {
enable true
reset()
include 'x86', 'armeabi-v7a', 'mips' //select ABIs to build APKs for
universalApk true //generate an additional APK that contains all the ABIs
}
}
project.ext.versionCodes = ['armeabi':1, 'armeabi-v7a':2, 'arm64-v8a':3, 'mips':5, 'mips64':6, 'x86':8, 'x86_64':9] //versionCode digit for each supported ABI, with 64bit>32bit and x86>armeabi-*
android.applicationVariants.all { variant ->
// assign different version code for each output
variant.outputs.each { output ->
output.versionCodeOverride =
project.ext.versionCodes.get(output.getFilter(com.android.build.OutputFile.ABI), 0) * 1000000 + defaultConfig.versionCode
}
}

In my react native project I earlier added aws amplify for push notification. After that I wanted to do analytics, so I added firebase to it. After that, my android app build but stops as soon as it launches.
I get error as

When you set up AWS Amplify push notifications, you have to first set up a Firebase project that AWS Amplify will hook into.
You can Enable Google Analytics in the Firebase project setup process.
Then include the line implementation 'com.google.firebase:firebase-analytics:17.2.1' in android/app/build.gradle.
I've created a walkthrough for the Firebase setup process for AWS Amplify, containing images for the various steps.
Yesterday my app was building correctly and today without changing anything I'm not able to build anymore, I'm getting this error:
Android dependency 'com.google.android.gms:play-services-stats' has >different version for the compile (16.0.1) and runtime (17.0.0) >classpath. You should manually set the same version via >DependencyResolution
I tried to bypass this with "com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true" and clean the project many times, but the error is still here.

Does someone know how to correct or bypass this version check ? Ask me if you need more informations.
This comment on github provides the answer to your question (and mine):
A dependency (react-native-device-info in this case) was using the latest version of one of its dependencies instead of a fixed/pinned version. When a new version of google services was released yesterday, it caused the build to pull in the new version for device-info, thereby causing the conflict with other dependencies that correctly pin the version they need.
The solution is to do what is explained in the linked post in your android/app/build.gradle:
implementation(project(":react-native-device-info"), {
exclude group: "com.google.android.gms"
})
implementation "com.google.android.gms:play-services-gcm:16.0.0"
and possibly replace react-native-device-info with any other dependency that may have the same problem (they would include a line like implementation "com.google.android.gms:play-services-gcm:+" which depends on whatever is the latest version of google gcm).
Add in the file: android/app/build.gradle
android {
...
dependencies {
implementation 'com.google.android.gms:play-services-maps:17.0.0'
}

For your information, I have these versions:
"react": "15.3.2",
"react-native": "0.34.1"
I'm trying to include a c file, ImageProc into my java file to use it's functions.
I got the code from a MjpegInputStream file (where everything is supposed to work, but of course its never that easy)
Here is the code that crashes (somehow the catch isn't catching it)
static {
try {
System.loadLibrary("ImageProc");
}
catch (Exception e){
e.getMessage();
}
}
The makefile is:
include $(CLEAR_VARS)
LOCAL_MODULE := ImageProc
LOCAL_SRC_FILES := ImageProc.c
LOCAL_LDLIBS := -llog -ljnigraphics
LOCAL_SHARED_LIBRARIES := prebuilt-libjpeg
LOCAL_C_INCLUDES := external/include jni/external/include
So to my understanding I should just be able to use ImageProc.
I know it went through and compiled the c file because at first it couldn't find the h file references (fixed now).
One other thing i'm not sure about is that I call the function pixeltobmp which in the c file is defined as Java_com_camera_simplemjpeg_MjpegInputStream_pixeltobmp which strikes me as odd. I tried changing the name of the method to include the package i'm using rather than the one I copied it from, but that didn't fix anything.
Any help is appreciated.
Additional info: I'm using gradle build 2.10
1. Compile your library
2. Check if you have the .so compiled library(this is important!)
3. In your gradle file add this:
android {
compileSdkVersion 23
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
sourceSets.main {
jni.srcDirs = []
File configFile = file('pathToYourLibsFolder')
jniLibs.srcDir configFile.absolutePath
}
Then it should work.
In build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
...
}
buildTypes {
...
}
ndk {
moduleName "ImageProc"
// stl "stlport_static"
// ldLibs "log"
}
}
}
As an alternative option, the code that you're using can be easily modified to remove the dependency on OpenCV (or it can now 2 years after you asked the question).
MjpegInputStream.java has two relevant methods, readMjpegFrame() and readMjpegFrame(Bitmap bmp).
Only the later relies on OpenCV and therefore the native library dependency. If you modify the code to remove this method, and then remove:
static {
System.loadLibrary("ImageProc");
}
public native int pixeltobmp(byte[] jp, int l, Bitmap bmp);
public native void freeCameraMemory();
You will no longer have this problem and can still use readMjpegFrame() to get the content you want.
Whether this is less performant, I'm not certain, but it's working fine in my use case.
My Gradle dependencies includes:
compile'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services-ads:8.1.0
I am getting BUILD FAILED with error:
Error:Execution failed for task ':app:processDebugResources.
Error: more than one library with package name 'com.google.android.gms'
You can temporarily disable this error with android.enforceUniquePackageName=false
However, this is temporary and will be enforced in 1.0
How can I solve this problem?
Use gradle androidDependencies to learn where the duplicate Google Play Services is coming from. Then use exclude to filter the duplicates out in your Gradle dependencies, e.g.
compile('something.that.includes.google.play.services:1.2.3') {
exclude group: 'com.google.android.gms'
}
I had the same problem and I solved by adding this line android.enforceUniquePackageName = false in build.gradle(app) like this:
buildTypes {
release {
...
... ...
}
}
android.enforceUniquePackageName = false
The easiest way is to replace these dependencies by the whole package :
compile 'com.google.android.gms:play-services:8.1.0'
Then you could probably compile it.
OR add android.enforceUniquePackageName = false in your build.gradle.
android {
compileSdkVersion Integer.parseInt(project.ANDROID_BUILD_SDK_VERSION)
buildToolsVersion project.ANDROID_BUILD_TOOLS_VERSION
defaultConfig {

targetSdkVersion Integer.parseInt(project.ANDROID_BUILD_TARGET_SDK_VERSION)
versionCode Integer.parseInt(project.VERSION_CODE)
versionName project.VERSION_NAME
}
buildTypes {
release {

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
android.packageBuildConfig = false
android.enforceUniquePackageName = false
