Cannot create org.webrtc.voiceengine.WebRtcAudioManager on Android

I have a functional implementation of native (C++) WebRTC in Windows, which I'm trying to get working on every other platform now. Currently, I'm attacking Android.
When I call webrtc::CreatePeerConnectionFactory, it cannot create the java class org.webrtc.voiceengine.WebRtcAudioManager. I get the following result (followed by a crash!):

This what that failing Java line looks like:
audioManager =
(AudioManager) ContextUtils.getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
I'm using WebRTC M103 (branch-heads/5060).
I've linked to libwebrtc.a, dynamically loaded libjingle_peerconnection_so.so, and bundled libwebrtc.jar. All of those seemed to be required dependencies, and advanced the ball for me one-by-one as I added them into the equation.

Fixed! This is what I was missing:
I was calling webrtc::JVM::Initialize prior to webrtc::CreatePeerConnectionFactory (which is one of many Droid specific requirements they don't bother mention in any docs...). But, I missed the fact there is an overload which takes the Droid app context (i.e. static void Initialize(JavaVM* jvm, jobject context);). That is to say, I was only passing the jvm pointer when initializing.
After a mini adventure (for which I'll omit the details) to get the context reference on C side, and not have it go "stale" (when the Java GC would delete it), I passed that along to the initialization. That, in turn, allowed that (original issue) of the Java invocation of ContextUtils.getApplicationContext() to work!

Facebook Audience Network not displaying test Ads. Already added TestDevice

I created a new sample project for displaying the Facebook audience network Banner ad at bottom of my activity.
My app is running in device but not displaying anything at bottom. I already added the hash for test device.

I'm getting the build successful and installed in my device. When I open the app I can't see any ads or test ads at bottom of my main activity.

If you've added Audience network libraries, you can add the code below to show test ads without worrying about adding a test device.
if (BuildConfig.DEBUG) {
AdSettings.setTestMode(true);
}
Add this code, preferably in your Application class.

First Implement this library:
implementation 'com.facebook.android:audience-network-sdk:4.99.1'
than use below code:
com.facebook.ads.AdView adView;
adView = new com.facebook.ads.AdView(this, "PLACEMENT-ID",
com.facebook.ads.AdSize.BANNER_HEIGHT_50);
((LinearLayout) adContainer).addView(adView);
adView.loadAd();

first, add this library to your grade file
implementation 'com.facebook.android:audience-network-sdk:6.12.0'
then paste this code in your xml file
<LinearLayout
android:id="#+id/banner_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical"
/>
In your Java code paste this code and also replace IMG_16_9_APP_INSTALL#YOUR_PLACEMENT_ID with your banner ad ID
adView = new AdView(this, "IMG_16_9_APP_INSTALL#YOUR_PLACEMENT_ID", AdSize.BANNER_HEIGHT_50);
LinearLayout adContainer = (LinearLayout) findViewById(R.id.banner_container);
adContainer.addView(adView);
adView.loadAd();

I created an example project based on google maps,in android studio, but it crashed when I run it. I use my smartphone for test it because my CPU not support VT-x.

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

Another thing, if I try to start an HelloWorld example without google maps activity, it does work.

Change this dependency (in your build.gradle):
compile 'com.google.android.gms:play-services:10.0.1'
For this one:
compile 'com.google.android.gms:play-services-maps:10.0.1'
to depend only on the maps component instead of depending on the whole Play Services library.

Firebase analytics event not show up on firebase console

I have implement firebase analytics in my app, but not show up any event or log in fire base console.
Add bellow code in each fragment in onCreateView() method.
private void addFragmentInFirebaseAnalytics() {
FirebaseAnalytics firebaseAnalytics = FirebaseAnalytics.getInstance(getContext());
FragmentItem fragmentItem = new FragmentItem();
fragmentItem.setFragmentId(Constant.FM_ID_MOIST_AIR);
fragmentItem.setFragmentName(MoistAirActivity.class.getSimpleName());
Bundle bundle = new Bundle();
bundle.putInt(FirebaseAnalytics.Param.ITEM_ID, fragmentItem.getFragmentId());
bundle.putString(FirebaseAnalytics.Param.ITEM_NAME, fragmentItem.getFragmentName());
//Logs an app event.
firebaseAnalytics.logEvent(FirebaseAnalytics.Event.SELECT_CONTENT, bundle);
Log.d(TAG,"bundle >>"+bundle);
}
Used dependency is :
compile 'com.google.firebase:firebase-core:9.4.0'
used plugin :
apply plugin: 'com.google.gms.google-services'
Its work fine and show log like this in debug console,

09-14 12:30:48.217 V/FA ( 8821): Inactivity, disconnecting from AppMeasurem
entService
but not show any uploading message in debug console and firebase console after 24 hours,
So, whats wrong here ? please help.

Finally i resolved this problem by replacing tools:node="replace" to tools:node="merge" and add tools:replace="android:label" in menifest file.
Reference : FirebaseApp with name [DEFAULT] doesn't exist

For me this worked:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
in the AndroidManifest.xml.
I've not specified any tools attribute.

There are a few things that could be going on here. You will see more diagnostic messages if you run:
adb shell setprop log.tag.FA VERBOSE
and if your test device has Google Play Services installed, also run:
adb shell setprop log.tag.FA-SVC VERBOSE
Those commands will display more information in your logcat. Are there any errors from FA or FA-SVC on application startup?

PAC support disabled because there is no system implementation

I've recently upgraded my Nexus 4 to Android 4.4. Whilst debugging my app, I discovered message W/chromium(14962): [WARNING:proxy_service.cc(888)] PAC support disabled because there is no system implementation
What does it mean ?

I think you can safely ignore this one. It is kinda hard-coded in Chromium Browser Engine.
If you check Chromium sources (https://chromium.googlesource.com/chromium/src.git/+/master/net/proxy/proxy_service.cc) and see ProxyService::CreateUsingSystemProxyResolver you will find
if (!ProxyResolverFactoryForSystem::IsSupported()) {
LOG(WARNING) << "PAC support disabled because there is no "
"system implementation";
return CreateWithoutProxyResolver(proxy_config_service, net_log);
}
where ProxyResolverFactoryForSystem::IsSupported() is just returning false if you're not on Windows or MacOS
class ProxyResolverFactoryForSystem : public ProxyResolverFactory {
//[...]
static bool IsSupported() {
#if defined(OS_WIN) || defined(OS_MACOSX)
return true;
#else
return false;
#endif
}
};
