Agora Android 示例應用程序在啟動時崩潰

Question

我能夠編譯項目，但它一啟動就崩潰了。 我已經在物理三星 Galaxy S8 和模擬的 Pixel 3 上對此進行了測試。兩者都產生了相同的結果。

它似乎在AGApplication.java的第 15 行崩潰。

mWorkerThread.start();

它產生錯誤：

E/AndroidRuntime: FATAL EXCEPTION: Thread-6
    Process: io.agora.openlive.voice.only, PID: 13997
    java.lang.RuntimeException: NEED TO check rtc sdk init fatal error
    java.lang.IllegalArgumentException: cannot initialize Agora Rtc Engine, error=101

我嘗試使用提供的 Gradel 配置通過 JCenter 集成 SDK，以及手動集成我從 Agora 下載的 SDK。

build.gradle：

apply plugin: 'com.android.application'

repositories {
    jcenter()
}

android {
    compileSdkVersion 26

    defaultConfig {
        applicationId "io.agora.openlive.voice.only"
        minSdkVersion 16 // ICE_CREAM_SANDWICH
        targetSdkVersion 26
        versionCode 19
        versionName "x.y.z"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    buildTypes {

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Answer 1

SDK 初始化 Agora 服務時返回 ERR_INVALID_APP_ID(101) 或調用 joinChannel 加入頻道時 onError 回調中報 ERR_INVALID_APP_ID(101) 錯誤。

原因：App ID無效，一般是App ID的數據格式不正確。

解決方法：檢查您的 App ID 的數據格式。 確保您使用正確的 App ID 來初始化 Agora 服務。

Answer 2

您是否更改了 string.xml 文件中的 appid？ 您需要從 Agora 控制台為您的應用程序生成一個 appid。 以下是有關如何獲取 appid 的說明： https://medium.com/@hermes_11327/how-to-get-started-with-agora-io-c73934bcab2b
