android - 声明 session 时 Opentok 应用程序崩溃

Question

我正在尝试学习如何使用 TokBox SDK。我刚刚开始编写一个简单的应用程序来显示视频，这样我就可以了解它是如何工作的。我的代码基于 https://tokbox.com/opentok/tutorials/connect-session/android/#connecting 中的示例。但是，每次我初始化 Session 对象时，我的应用程序都会停止工作。我试过用 try/catch block 围绕它，但它仍然崩溃。我的代码如下:

package com.example.ben.toktest;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.RelativeLayout;

import com.opentok.android.Session;

public class MainActivity extends Activity{
    private static final String API_KEY= "12345678"; //replaced api key with 12345678 for privacy purposes
    RelativeLayout container;
    Session session;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        container = (RelativeLayout) findViewById(R.id.main);

        session = new Session(MainActivity.this, "12345678", "2_MX40NTEwMjczMn5-MTQxODAyMDUwMjgwMn5PTjdlRDBvSDVYOHBkelZjby80eGZuclN-fg"); //Crashes here
        /*session.setSessionListener(new Session.SessionListener() {
            @Override
            public void onConnected(Session session) {

            }

            @Override
            public void onDisconnected(Session session) {

            }

            @Override
            public void onStreamReceived(Session session, Stream stream) {
                mStreams.add(stream);
                subscriber = new Subscriber(MainActivity.this, stream);
                subscriber.setSubscriberListener(new SubscriberListener() {
                    @Override
                    public void onConnected(SubscriberKit subscriberKit) {
                        LayoutParams params = new LayoutParams(getResources().getDisplayMetrics().widthPixels, getResources().getDisplayMetrics().heightPixels);
                        container.addView(subscriberKit.getView(), params);
                    }

                    @Override
                    public void onDisconnected(SubscriberKit subscriberKit) {

                    }

                    @Override
                    public void onError(SubscriberKit subscriberKit, OpentokError opentokError) {

                    }
                });
                session.subscribe(subscriber);

            }

            @Override
            public void onStreamDropped(Session session, Stream stream) {

            }

            @Override
            public void onError(Session session, OpentokError opentokError) {

            }
        });*/

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

我的 logcat 的输出是:

有人可以告诉我为什么它总是崩溃吗？我不知道我做错了什么!

我在尝试使用 Android Studio 运行 OpenTok 示例应用程序时遇到了同样的问题。

试试这个:

1) 打开您的 app/build.gradle 文件并添加行

编译文件('libs/opentok-android-sdk-2.2.1.jar')

在依赖下。

2) 在您的应用程序文件夹下创建一个文件夹libs(如果它还不存在的话)

3) 将 OpenTok JAR 文件 (opentok-android-sdk-2.3.1.jar) 从 OpenTok SDK libs 文件夹复制到您的app/libs 文件夹

4) 在app/src/main/下创建文件夹jniLibs

5) 将文件夹 armeabi 和 x86 从 OpenTok SDK libs 文件夹复制到 jniLibs 文件夹，然后运行您的应用。

希望对您有所帮助!
