Opentok应用程序在声明会话时崩溃

Question

我在学习如何使用TokBox SDK。我只是开始写一个简单的应用程序来显示视频，以便我可以了解它的工作原理。我在https://tokbox.com/opentok/tutorials/connect-session/android/#connecting上找到的示例基于我的代码。但是，每次我初始化Session对象时，我的应用程序都停止工作。我尝试用try/catch块来围绕它，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); 
    } 
} 

从我logcat的输出是：

有人能告诉我为什么它总是崩溃？我不知道我做错了什么！

Answer 1

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

试试这个：

1）打开你的应用程序/文件的build.gradle并添加行

编译文件（ '库/ opentok-Android的SDK-2.2.1.jar'）

依赖项下。

2）创建一个文件夹库您的应用程序文件夹下（如果它尚不存在）

3）复制OpenTok JAR文件（opentok-Android的SDK-2.3.1.jar）在OpenTok SDK库文件夹到你应用程序/库文件夹

4）创建的文件夹jniLibs下的应用程序/ src目录/主/

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

我希望它有帮助！
