Mapbox LocationEngineResult.getLastLocation always return null

I'm creating a cordova plugin that should return the device's position using mapbox. The issue is that LocationEngineResult.getLastLocation() is always returning null.
I use locationEngine to retrieve the location with locationCallback.
Permissions are also checked.
***
LocationEngine locationEngine;
AltGeolocationLocationCallback callback = new AltGeolocationLocationCallback(this);
***

private void initLocationEngine() {
locationEngine = LocationEngineProvider.getBestLocationEngine(this.cordova.getActivity().getApplicationContext());
LocationEngineRequest request = new LocationEngineRequest.Builder(DEFAULT_INTERVAL_IN_MILLISECONDS)
.setPriority(LocationEngineRequest.PRIORITY_HIGH_ACCURACY)
.setMaxWaitTime(DEFAULT_MAX_WAIT_TIME).build();
locationEngine.requestLocationUpdates(request, callback, Looper.getMainLooper());
locationEngine.getLastLocation(callback);
}
private static class AltGeolocationLocationCallback extends Activity
implements LocationEngineCallback<LocationEngineResult> {
private final WeakReference<AltGeolocation> activityWeakReference;
private AltGeolocationLocationCallback contexto = this;
AltGeolocationLocationCallback(AltGeolocation activity) {
this.activityWeakReference = new WeakReference<>(activity);
}
#Override

if (activity != null) {

Log.d(LOG_TAG, "result: " + location );

Both local and remote video call display black screen but audio works fine in agora

I am trying out agora sdk sample on android using java. when I run the app on my phone and remote device the audio actually works well but the video shows black screen. How do I solve this issue.
I have tried what was stated on agora docs but non worked for me.
I have checked permissions they are working fine
My front camera is working fine
I enabled the video on my code.

I dont really know what is the issue. Anyone have idea on how I can solve this issue?

I found the solution for this
you have to add delay of 10 seconds before running below code
mRtcEngine!!.setClientRole(Constants.CLIENT_ROLE_BROADCASTER)
mRtcEngine!!.joinChannel(
stringToken,
channelName,
"Extra Optional Data",
currentUid
)
so the surface view of current user is loaded properly first and then it tries to join the call.
Simply put, dont join channel before surface view and camera is ready.

setOnUtteranceProgressListener not at all working for Text To Speech for API > 21

I want setOnUtteranceProgressListener should notify a Toast after the speech is completed.It seems not working.
I have used setOnUtteranceProgressListener and on the speak function i have mentioned the paramaters as follows..
Bundle params = new Bundle();
params.putString(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, MainActivity.this.getPackageName());
I have given a "UniqueId" while calling speak function as follows.
myTTS.speak(message,TextToSpeech.QUEUE_FLUSH,params,"UniqueId");
In My program after the text to speech engine finishes speaking it should run a Toast notifying that it has finished speaking.But the setOnUtteranceProgressListner seems not working.
myTTS.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
}
#Override
public void onDone(String utteranceId) {
Toast.makeText(MainActivity.this,"Finished speaking.",Toast.LENGTH_LONG).show();
}
#Override
public void onError(String utteranceId) {
}
});
The all Code is as follows..
public class MainActivity extends AppCompatActivity {
String message;
private TextToSpeech myTTS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myTTS = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(myTTS.getEngines().size() == 0){
Toast.makeText(MainActivity.this,"No Engines Installed",Toast.LENGTH_LONG).show();
}else{
myTTS.setLanguage(Locale.US);
if (status == TextToSpeech.SUCCESS){
//Toast.makeText(MainActivity.this,"Status working.",Toast.LENGTH_LONG).show();
message = "How may i help you.";
}
}
}
});
myTTS.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
}
#Override
public void onDone(String utteranceId) {
Toast.makeText(MainActivity.this,"onDone working.",Toast.LENGTH_LONG).show();
}
#Override
public void onError(String utteranceId) {
}
});
}
Please give a solution for this.

The main problems are:
1) Setting the progress listener before the tts is initialized.
2) Trying to make a Toast from a background thread.
I also have some other suggested changes but they are not required:
public class MainActivity extends AppCompatActivity {
String message = "How may I help you?";
String mostRecentUtteranceID;
private TextToSpeech myTTS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myTTS = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(myTTS.getEngines().size() == 0){
Toast.makeText(MainActivity.this,"No Engines Installed",Toast.LENGTH_LONG).show();
}else{
if (status == TextToSpeech.SUCCESS){
ttsInitialized();
}
}
}
});
}
private void ttsInitialized() {
// *** set UtteranceProgressListener AFTER tts is initialized ***
myTTS.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
}
#Override
// this method will always called from a background thread.
public void onDone(String utteranceId) {
// only respond to the most recent utterance
if (!utteranceId.equals(mostRecentUtteranceID)) {
Log.i("XXX", "onDone() blocked: utterance ID mismatch.");
return;
} // else continue...
boolean wasCalledFromBackgroundThread = (Thread.currentThread().getId() != 1);
Log.i("XXX", "was onDone() called on a background thread? : " + wasCalledFromBackgroundThread);
Log.i("XXX", "onDone working.");
// for demonstration only... avoid references to
// MainActivity (unless you use a WeakReference)
// inside the onDone() method, as it
// can cause a memory leak.
runOnUiThread(new Runnable() {
#Override
public void run() {
// *** toast will not work if called from a background thread ***
Toast.makeText(MainActivity.this,"onDone working.",Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onError(String utteranceId) {
}
});
// set Language
myTTS.setLanguage(Locale.US);
// set unique utterance ID for each utterance
mostRecentUtteranceID = (new Random().nextInt() % 9999999) + ""; // "" is String force
// set params
// *** this method will work for more devices: API 19+ ***
HashMap<String, String> params = new HashMap<>();
params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, mostRecentUtteranceID);
myTTS.speak(message,TextToSpeech.QUEUE_FLUSH,params);
}
}

If you want to add the call back OnUtteranceProgressListener you have to implement the speak method like this:
myTTS.speak(message,TextToSpeech.QUEUE_FLUSH, null , TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID);
Then it will call the methods that you've already implemented (onStart, onDone, etc)

Interstitial Ad returns a null value

I programmed an app named "Trumple Run" for android. Like the name says it is a Jump & Run game and I want to release it soon. Before that I would like to implement Interstitial Ads from AdMob. I followed the official guide for the implementation of Ads but the app always crashes when I tried to show the add. Here is some code from my MainActivity (info: I cut out code which is not relevant for the issue; the method addzeigen() is called from another class)
public class Main_activity extends Activity {
private InterstitialAd mInterstitial;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //Fullscreen
DisplayMetrics metrics = getResources().getDisplayMetrics(); //Display größe herausfinden
V.Bildbreite = metrics.widthPixels;
V.Bildhöhe = metrics.heightPixels;
addladen();
V.v = new View(this);
setContentView(V.v);
}
public void addladen(){
mInterstitial = new InterstitialAd(this);
mInterstitial.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
AdRequest request = new AdRequest.Builder().build();
mInterstitial.loadAd(request);
}
public void addzeigen(){
if(mInterstitial.isLoaded()){
mInterstitial.show();
addladen();
}
}
I looked at the StackTrace to find the reason for the issue and this two lines indicated that the interstitial is not yet instantiated (returning a null value).
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.google.android.gms.ads.InterstitialAd.isLoaded()' on a null object reference
Because of that I added a null checker in my addladen() method to prevent a crash.
public void addzeigen(){
if(mInterstitial != null && mInterstitial.isLoaded()){
mInterstitial.show();
addladen();
}
}
But why is my Interstitial object null? Did I not instantiate it in the right way in my addladen() method? I already searched for a long time in the internet but found no solution and asked the AdMob support but they said I should ask here because it is an implementation problem. How do I have to modify my code to make sure that my Interstitial is not null? I would be really happy if you could help me.

create application to when open app, add immidiate load
public class MyApplication extends Application {
public InterstitialAd mInterstitialAd;
private AppOpenManager appOpenAdManager;
private Activity currentActivity;
private int check = 0;
public AdLoader adLoader;
#Override
public void onCreate() {
super.onCreate();
MobileAds.initialize(
this,
new OnInitializationCompleteListener() {
#Override
public void onInitializationComplete(
#NonNull InitializationStatus initializationStatus) {
}
});
appOpenAdManager = new AppOpenManager();
loadInterstitial(AD_UNIT_ID_INTERSTITIAL_ADS);
}
public void loadInterstitial(String id) {
AdRequest adRequest = new AdRequest.Builder().build();
InterstitialAd.load(
this,
id,
adRequest,
new InterstitialAdLoadCallback() {
#Override
public void onAdLoaded(#NonNull InterstitialAd interstitialAd) {
mInterstitialAd = interstitialAd;
interstitialAd.setFullScreenContentCallback(
new FullScreenContentCallback() {
#Override
public void onAdDismissedFullScreenContent() {
mInterstitialAd = null;
}
#Override
public void onAdFailedToShowFullScreenContent(AdError adError) {
// Called when fullscreen content failed to show.
// Make sure to set your reference to null so you don't
// show it a second time.
mInterstitialAd = null;
}
#Override
public void onAdShowedFullScreenContent() {
}
});
}
#Override
public void onAdFailedToLoad(#NonNull LoadAdError loadAdError) {
mInterstitialAd = null;
}
});
}
}
then you create class check exception happen when load and open app
public class LoadInterstitialAds {
private static LoadInterstitialAds instance;
private InterstitialAd mInterstitialAd;
public static LoadInterstitialAds getInstance() {
if (instance == null) {
return new LoadInterstitialAds();
}
return instance;
}
public void openAdsThenOpenActivity(Activity activity, InterstitialAdsListener listener) {
Application application = activity.getApplication();
if (application instanceof MyApplication) {
LoadInterstitialAds.this.mInterstitialAd = ((MyApplication) application).mInterstitialAd;
if (LoadInterstitialAds.this.mInterstitialAd != null) {
LoadInterstitialAds.this.mInterstitialAd.show(activity);
LoadInterstitialAds.this.mInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback() {
#Override
public void onAdDismissedFullScreenContent() {
listener.onStartActivity();
((MyApplication) application).loadInterstitial(AD_UNIT_ID_INTERSTITIAL_ADS);
}
#Override
public void onAdFailedToShowFullScreenContent(#NonNull AdError adError) {
((MyApplication) application).loadInterstitial(AD_UNIT_ID_INTERSTITIAL_ADS);
listener.onStartActivity();
}
});
} else {
((MyApplication) application).loadInterstitial(AD_UNIT_ID_INTERSTITIAL_ADS);
listener.onStartActivity();
}
}
}
}
create interface listener tothe convenience of calling
public interface InterstitialAdsListener {
void onStartActivity();
}
and finally, run this code at any where you want to show
LoadInterstitialAds loadInterstitialAds = LoadInterstitialAds.getInstance();
loadInterstitialAds.openAdsThenOpenActivity(getActivity(), ()->{
// your process
});

Loading multiple AdMob videos

For demonstration purposes, the app has one activity that simply offers this:
You click a button, view a rewarded video, and you are rewarded with whatever.
The Problem
How can I load the videos? From what I have seen you can only call mAd.loadAd() once. There are 3 videos, each with their own AD UNIT ID. Each ad unit can have its own listener, but only one video loads so it doesn't matter...
When trying to load multiple videos
For example:
mAd1.loadAd("AD_UNIT_1", new AdRequest.Builder().build());
mAd2.loadAd("AD_UNIT_2", new AdRequest.Builder().build());
mAd3.loadAd("AD_UNIT_3", new AdRequest.Builder().build());
results in only the last video being loaded and this in log:
W/Ads: Loading already in progress, saving this object for future refreshes.
onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAd1 = MobileAds.getRewardedVideoAdInstance(this);
mAd2 = MobileAds.getRewardedVideoAdInstance(this);
mAd3 = MobileAds.getRewardedVideoAdInstance(this);
listeners...
mAd1.loadAd() etc
}
Thank you for your help
Edit: It's clear I am thinking about this problem wrong. I have 5+ ad zones that each will play a rewarded video and give a different reward (for example, one gives coins, one gives a level up, and so on..). There is no reason to load 5 videos. I should load one in onCreate(), so it's ready when needed, then load it again after the item is rewarded so it's ready for next time.
So the question remains, if there is just the one video, and thus one ad zone, being loaded onCreate() then how can I track what reward to give?

Here's a simple solution...
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAd = MobileAds.getRewardedVideoAdInstance(this);
mAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
#Override
public void onRewarded(RewardItem rewardItem) {
switch(Constants.currentAd) {
case("REWARD1"):
//do something
Constants.currentAd = "";
break;
case("REWARD2"):
//do something
Constants.currentAd = "";
break;
case("REWARD3"):
//do something
Constants.currentAd = "";
break;
}
}
});
mAd.loadAd("REWARDED_VIDEO_UNIT_ID", new AdRequest.Builder().build());
}
public void showRewardedVideo() {
if (mAd.isLoaded()) {
mAd.show();
}
}
Constants.java
public class Constants {
public static String currentAd = "";
}
Showing the ad after button click
rewardButton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Constants.currentAd = "REWARD1";
dismiss();
((MainActivity) getActivity()).showRewardedVideo();
}
});
REWARDED_VIDEO_UNIT_ID is one ad unit for rewarded video in AdMob...remove the rest. No need for other units, you can track whatever you like in the listener.

Other simple soluction...
AbstractRewardVideo.java
public abstract class AbstractRewardVideo {
private RewardedVideoAd mAd;
private String adId = "ca-app-pub...";
private Activity activity;
abstract protected RewardedVideoAdListener getListener();

} else {
