Agora.io audio working but video not transmitting

I am new to Agora.io and I am creating an android app for 1 to 1 video calling. Everything is working fine in my app - I can join/leave the channel and even see my own local image through my camera. However, in the call, only the audio is being transmitted and video is not being transmitted.
When I debug the app, I can see that the event 'onFirstRemoteVideoFrame' is not being triggered. I tried changing it to 'onFirstRemoteVideoDecoded'(which I saw in many tutorials but android studio says the method is depreciated) but it is still not working.
Also, please note that when I add the line '-keep class io.agora.**{;}' in my proguard-rules.pro file, it says that it can't find the class. So instead I am using '-keep class io.agora.{*;}'.
Below is the java code for my activity. I am using agora 3.1.3.

You can try "onRemoteVideoStateChanged" callback instead of "onFirstRemoteVideoFrame".
Here is the code snippet:
#Override
public void onRemoteVideoStateChanged(final int uid, int state, int reason, int elapsed) {
super.onRemoteVideoStateChanged(uid, state, reason, elapsed);
if (state == Constants.REMOTE_VIDEO_STATE_STARTING) {
runOnUiThread(new Runnable() {
#Override
public void run() {
setupRemoteVideo(uid);
}
});
}
}

I think problem might be here. You have just declared your variable
private SimpleFacebook mSimpleFacebook;
you haven't initialized that variable so you got NPE
So initialized it on onCreateView() method.
mSimpleFacebook = SimpleFacebook.getInstance(getActivity());
And yet you get error then you need to finally change
mSimpleFacebook = SimpleFacebook.getInstance();
Add this line to manifest file..
<activity android:name="com.facebook.LoginActivity" android:screenOrientation="portrait" android:configChanges="keyboardHidden|orientation">
</activity>
which would be finally works for you.!!

When i click on the button, the ListView opens but with no data i.e. Empty set.
Contacts_View.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<ListView

<TextView android:id="#android:id/empty"

</LinearLayout>
What i mean here is that both the functions are identical.getGPosts() is called in the FBAppActivity whereas the createAdapter() is called in MessagesActivity.getGPosts() works but createAdapter() does not. Kindly help me understand why is this happening.
Basically i am trying to import posts from a facebook group. My Toast object is working fine from the getGPosts() [it is in the FBAppActivity class] function. This function getGPosts() is called on the button click.I verified that i am getting the data using the Toast object. Now i want to populate the data to a ListView. Which i am unable to do. I have tried various methods, but none has worked out for me.

Because you're calling the setListAdapter(adapter) for implicit (Activity's) ListView in the onCreate(Bundle savedInstanceState) method and in the getGPosts() method you reference the correct (visible) ListView.
Simply change the mentioned call in the onCreate(Bundle savedInstanceState) method to:
myListView = getListView();
myListView.setAdapter(adapter);
And you should be fine! Good luck!
P.S. This solution will work if your ListActivity follows the following requirement:
your own view MUST contain a ListView object with the id "#android:id/list"
from Google's documentation

As I see you are extending ListActivity. So below code must throw a NPE.
lv = (ListView)findViewById(R.id.list);
lv.setAdapter(adapter);
You should use below code at onComplete method instead;
setListAdapter(adapter);
or
getListView().setAdapter(adapter);

You have to show your friend's profile picture with URL only.
You have to use only URL for showing your frnds profile picture.(This facility is given by Facebook)
you can show your friend's profile picture with Lazy Loading ..

Android TTS onUtteranceCompleted callback isn't getting called

I am trying to get the Android TTS API to read my "utterance" and then call the onUtteranceCompleted() listener unsuccessfully. I've registered my TTS object and it returns SUCCESS, so I can't figure out for the life of me why my callback isn't getting called.
I've tried searching for help, but it seems others have difficulty with this too. Am I missing something simple?
Thanks for any help you can offer.
package com.test.mytts;
import java.util.HashMap;
import android.app.Activity;
import android.media.AudioManager;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.speech.tts.TextToSpeech.OnUtteranceCompletedListener;
import android.widget.TextView;
import android.widget.Toast;
public class MyTTS extends Activity implements OnInitListener, OnUtteranceCompletedListener
{
TextView tv;
private TextToSpeech _tts;
#Override
public void onCreate(Bundle savedInstanceState)
{
tv = new TextView(this);
tv.setText("MyTTS: ");
super.onCreate(savedInstanceState);
setContentView(tv);
_tts = new TextToSpeech(this, this);
}
#Override
public void onInit(int status)
{
HashMap<String, String> myHashAlarm = new HashMap<String, String>();
myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_NOTIFICATION));
myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "test");
if (status == TextToSpeech.SUCCESS)
{
Toast.makeText(this, "Trying to speak...", Toast.LENGTH_SHORT).show();
int result = _tts.setOnUtteranceCompletedListener(this);
tv.append(String.valueOf(result));
_tts.setSpeechRate((float) .5);
_tts.speak("Testing one, two, three", TextToSpeech.QUEUE_ADD, myHashAlarm);
}
else
Toast.makeText(this, "Failed to initialize TTS.", Toast.LENGTH_SHORT).show();
}
#Override
public void onUtteranceCompleted(String utteranceId)
{
Toast.makeText(this, "onUtteranceCompleted", Toast.LENGTH_SHORT).show();
}
#Override
public void onDestroy()
{
super.onDestroy();
_tts.shutdown();
}
}

Call the setOnUtteranceCompletedListener inside the onInit function of the tts object.
If you want to make any changes to the UI on the call of the onUtteranceCompleted function, add the code inside a runOnUIThread method.
And do remember to add the Hashmap param value while calling the speak() function
Example :
TextToSpeech tts= new TextToSpeech(context, new OnInitListener() {
#Override
public void onInit(int status) {
mTts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
#Override
public void onUtteranceCompleted(String utteranceId) {
runOnUiThread(new Runnable() {
#Override
public void run() {
//UI changes
}
});
}
});
}
});
HashMap<String, String> params = new HashMap<String, String>();
params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
tts.speak("Text to Speak",TextToSpeech.QUEUE_FLUSH, params);

I believe that unless you specify an utterance with an id, like:
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, utteranceid);
your utterance completed method will not be called.
in this case, map is the Hashmap you pass to the engine when you speak.

this will work for you on API Level >=15
