Missing libarcade.so file

[sadaharusong]

Hello, I use libpng.so instead libpng16.so to solve the problem . But now, I have a new problem, it is missing libarcade.so in the file. I try to use ndk to build it , but if want to use ndk to build the .so , the libarcade.so in needed . So could you update the Code or Push the file into the repository ?

You need to run ndk-build to generate libarcade.so then you can run from AndroidStudio

D:\AndroidStudioProjects\Arcade\arcade\src\main\jni>ndk-build Android NDK: ERROR:D:/AndroidStudioProjects/Arcade/arcade/src/main/jni/Android.m k:arcade: LOCAL_SRC_FILES points to a missing file Android NDK: Check that D:/AndroidStudioProjects/Arcade/arcade/src/main/jni/preb uilts/libarcade.so exists or that its path is correct D:/Android/sdk/ndk-bundle/build//../build/core/prebuilt-library.mk:45: *** Andro id NDK: Aborting . Stop.

I know need to run ndk-bulid. But it says I missing file .So, I check the file in jni ,the file is right there . In Android.mk the 'LOCAL_SRC_FILES' shows "LOCAL_SRC_FILES := arcade.cpp torchandroid.cpp android_fopen.c" , but in my jni ,the file is right , didn't miss.

I slove the problem , but I have a new one.Just need one step I can build the .so .

You miss librt.so, but this lib is merged to libc.so already. I resolve this problem by this way, maybe it is wrong, I just want to make it work, and it works finally.

comment

#APP_CFLAGS += -fopenmp
#APP_LDFLAGS += -fopenmp

in Application.mk, then run ndk-build, you might get the so.

There are still many problems waiting for you. Hope we can help each other.

[sadaharusong]

@huyn Thank you very much . And I fix the problem , build success . I found the "libarcade.so" , but it still says error in Android Studio ,when I click the button "BEGIN STYLING " , Do you have this error ?

Like this :

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.naman14.arcade-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]] couldn't find "libarcade.so"

[naman14]

@sadaharusong what's your device architecture? The prebuilt libraries are currently only for armeabi-v7a I will try to revisit the project today and see if there are any build issues

[naman14]

Also, can you post your Android.mk?

[sadaharusong]

@naman14 I try to use the phone with armeabi-v7a , and also try other phone have other cpu . All didn't work .

The Error : java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.naman14.arcade-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]] couldn't find "libarcade.so"

By the way , The App in Google Play is didn't work,too.

@naman14 Nice to know that you will take a look in to the issues. I can offer help if there is need.

Yes, please take a look in #2.

[huyn]

@sadaharusong That is because all the so files are not packed into final apk try

android.sources {

        main {
            jniLibs {
                source {
                    srcDirs 'libs'
                }
            }
        }

        main {
            jni {
                exportedHeaders {
                    srcDir "src/main/jni/include"
                }
                source {
                    srcDirs = ['src/main/none'] // [] could be set instead but will disable even symbol resolution inside the editor
                }
            }
        }
    }

change your srcDirs of jniLibs to libs folder under arcade module. It would work.

Have you solved that issue please? I'm having the same :(

[acenter2507]

@naman14 do you still following this project ?
