Hi! I'm trying the usbCameraTest0 on my Android and when I select the USB camera it gave me the next error:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.serenegiant.usbcameratest0, PID: 13261 java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/com.serenegiant.usbcameratest0-AeCN71iEUUMdhjpfB3peuA==/base.apk"],nativeLibraryDirectories=[/data/app/com.serenegiant.usbcameratest0-AeCN71iEUUMdhjpfB3peuA==/lib/arm64, /system/lib64]]] couldn't find "libjpeg-turbo1500.so" at java.lang.Runtime.loadLibrary0(Runtime.java:1012) at java.lang.System.loadLibrary(System.java:1669) at com.serenegiant.usb.UVCCamera.<clinit>(UVCCamera.java:121) at com.serenegiant.usbcameratest0.MainActivity$2$1.run(MainActivity.java:182) at android.os.Handler.handleCallback(Handler.java:873) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:6746) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

It happened in System.loadLibrary("jpeg-turbo1500"); of UVCCamera class.

I'll appreciate any help, thanks.

Hi @emejoti, check if these libraries are included in your apk or not. You can browse it with an archive manager.

jumpy88 commented 3 years ago

Also, remember to check it is there for the right architecture (arm64-v8a, armeabi-v7a...) matching your set up.

emejoti commented 3 years ago

Thanks for your comments, the error was on the gradle.

jumpy88 commented 3 years ago

Not at all. How did you solve it? Just in case someone else met the same error.

emejoti commented 3 years ago

I guess I did something wrong when I include the libraries, I fixed it changing the source in the libuvccamera build gradle.

zipswich commented 2 years ago

In my case, I have to add arm64-v8a to Application.mk under UVCCamera\libuvccamera\src\main\jni APP_ABI := armeabi-v7a arm64-v8a x86

@emejoti I'm having the same problem, can I ask what you changed the source to when you included the libraries? Thank you so much - I've been struggling with this one for a little while.
