android - 使用 Twilio JavaI420Buffer (Kotlin) 时出现 UnsatisfiedLinkError

Question

描述
尝试通过以下调用分配 JavaI420Buffer 时:

tvi.webrtc.JavaI420Buffer.allocate(width, height)

我收到以下错误:

java.lang.UnsatisfiedLinkError: No implementation found for java.nio.ByteBuffer tvi.webrtc.JniCommon.nativeAllocateByteBuffer(int) (tried Java_tvi_webrtc_JniCommon_nativeAllocateByteBuffer and Java_tvi_webrtc_JniCommon_nativeAllocateByteBuffer__I)
        at tvi.webrtc.JniCommon.nativeAllocateByteBuffer(Native Method)
        at tvi.webrtc.JavaI420Buffer.allocate(JavaI420Buffer.java:87)
        at dji.ux.beta.core.widget.fpv.FPVWidget$onSurfaceTextureAvailable$yuvDataListener$1.onYuvDataReceived(FPVWidget.kt:417)

在此错误之前，我还得到:

奇怪的是，如果我声明使用官方 org.webrtc 库( implementation 'org.webrtc:google-webrtc:1.0.32006' )，那么本地调用分配字节缓冲区就会成功。

Answer 1

First of all when you load native code in kotlin it should be like this:

companion object {
    init {
        System.loadLibrary("jingle_peerconnection")
    }
}

In Java

static {
    System.loadLibrary("jingle_peerconnection")
}

Second as per your error, "library "libjingle_peerconnection_so.so" not found => you have to add related Android architectures folder in "main -> java -> libs" folder

Example : main -> java -> libs -> x86 -> .so file
