Android：使用 Opus lib 时无法加载 pjsua2

Question

我在我的 android 项目中使用 PJSIP，它运行良好。现在，我需要在我的项目中添加 Opus-Android 库。代码编译得很好，但是在启动应用程序时会出现问题。它给了我以下例外：

一旦我从 gradle 中删除 Opus，pjsip 库就会开始正常工作。

这是我的依赖项：

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})

compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:support-v4:25.2.0'
compile 'ch.acra:acra:4.9.0'
compile 'org.java-websocket:Java-WebSocket:1.3.0'
compile 'top.oply.opuslib:opuslib:1.0.2'
testCompile 'junit:junit:4.12'
}

我的应用程序的 gradle：

compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "com.matsoltech.android.chatellite"
        minSdkVersion 11
        targetSdkVersion 25
        versionCode 1
        versionName code.toString()
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        ndk {
            moduleName "libpjsua2"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

        debug {
            jniDebuggable true
        }

    }

而抛出的异常在这里：

static {

    System.loadLibrary("pjsua2");
    System.out.println("Library loaded");
}

那么，我哪里做错了？

你需要这个，然后你的代码应该可以工作。
