我正在尝试学习如何使用 TokBox SDK。我已经开始编写一个简单的应用程序来显示视频，以便了解它的工作原理。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 块包围它，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！
