无法解析符号 BrightcovePlayer

Question

我正在按照 brightcove-native-sdk-android 的 quick start 来实现媒体播放器。

与 build.gradle 的同步通过正常，但是在构建我的应用程序时，出现错误：

无法解析符号 'BrightcovePlayer'。

我认为这与快速入门中提到的存储库有关，但无法破解根本原因。也关注了这些问题：

目前我的代码如下所示：

MainActivity.java

package com.example.jchavarr.helloworld;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.R;

public class MainActivity extends BrightcovePlayer  {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        brightcoveVideoView  = (BrightcoveExoPlayerVideoView) findViewById(R.id.brightcove_video_view);
    }
}

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.brightcove.playvideos.MainActivity">

        android:layout_height="280dp"
        android:layout_gravity="center"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
    />

</android.support.constraint.ConstraintLayout>

            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>

build.gradle（应用程序）

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.example.jchavarr.helloworld"
        minSdkVersion 23
        targetSdkVersion 25

        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    maven {
        url 'http://repo.brightcove.com/releases'
    }
}

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-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile "com.brightcove.player:exoplayer:4.4+" //**
    //compile 'com.brightcove.player:android-sdk:6.+'
    //compile "com.brightcove.player:android-appcompat-plugin:${anpVersion}"
    testCompile 'junit:junit:4.12'
}

我需要下载某些文件的 AAR 吗？ URL http://repo.brightcove.com/releases 是正确的存储库吗？是否需要放置包裹：package com.brightcove.playvideos;在 MainActivity.java

Answer 1

此修复正在导入一些在快速入门指南中未提及的必需软件包：

import com.brightcove.player.model.DeliveryType;
import com.brightcove.player.model.Video;
import com.brightcove.player.view.BrightcoveExoPlayerVideoView;
import com.brightcove.player.view.BrightcovePlayer;
