Sinch Service not starting in Android - java

I was trying out the sample programs provided by Sinch and was getting a NullPointerException. I traced the code and found that it was caused by my device not connecting to the SinchService.
The code is as follows
public class LoginActivity extends BaseActivity implements SinchService.StartFailedListener {
private Button mLoginButton;
private EditText mLoginName;
private ProgressDialog mSpinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
mLoginName = (EditText) findViewById(R.id.loginName);
mLoginButton = (Button) findViewById(R.id.loginButton);
mLoginButton.setEnabled(false);
mLoginButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
loginClicked();
}
});
}
#Override
protected void onServiceConnected() {
mLoginButton.setEnabled(true);
getSinchServiceInterface().setStartListener(this);
}
#Override
protected void onPause() {
if (mSpinner != null) {
mSpinner.dismiss();
}
super.onPause();
}
#Override
public void onStartFailed(SinchError error) {
Toast.makeText(this, error.toString(), Toast.LENGTH_LONG).show();
if (mSpinner != null) {
mSpinner.dismiss();
}
}
#Override
public void onStarted() {
openPlaceCallActivity();
}
private void loginClicked() {
String userName = mLoginName.getText().toString();
if (userName.isEmpty()) {
Toast.makeText(this, "Please enter a name", Toast.LENGTH_LONG).show();
return;
}
if (!getSinchServiceInterface().isStarted()) {
getSinchServiceInterface().startClient(userName);
showSpinner();
} else {
openPlaceCallActivity();
}
}
private void openPlaceCallActivity() {
Intent mainActivity = new Intent(this, PlaceCallActivity.class);
startActivity(mainActivity);
}
private void showSpinner() {
mSpinner = new ProgressDialog(this);
mSpinner.setTitle("Logging in");
mSpinner.setMessage("Please wait...");
mSpinner.show();
}
}
I could see that since the service is not connecting I am not getting a correct output when I call getSinchServiceInterface(). It always returns null. My device is connected to the internet and the backend app in the Sinch dashboard seems to be working fine too.

What could be the cause of this error and how to solve it?
UPDATE:
I exactly copy pasted the android code downloaded from this page. I am using sinch-rtc-sample-calling app from that file. I compiled and ran the app separately and it was working fine. Then I copy pasted all the java and xml from that app into the one which I am working and it is not working. Why is this happening. This might be the reason for the NullPointerException. After copy pasting I found that the login button is disabled. That means the onServiceConnected() is not executing. I tried calling it manually and that is resulting in the NPE, but that is happening correctly in the standalone app. I am getting these kind of problems only upon integration.
PS : I updated the manifest and gradle as per the new files.

Have had the same issue over the past few days.
In my case it is because I hadn`t added the following in the manifest under application node
<service android:name=".SinchService"/>
Make sure that the setting is in your application manifest. That solved it for me.

everything looks fine, uncomment the commented part because there is one condition which is being checked and it returns
private boolean isStarted() {
return (mSinchClient != null && mSinchClient.isStarted());
}
before getting SinchService and Also check your
private static final String APP_KEY = "app_key";
private static final String APP_SECRET = "app_secret";
private static final String ENVIRONMENT = "sandbox.sinch.com";
in SinchService.java, are the correct or not.

NullPointerException Context errors on code moved from one working source into a Main application

Context is not a strong point of mine, I keep getting this error this is part of code i have moved over from another application and works in there just fine, however i am trying to transplant the code from the smaller app to this main app, as adding it as a library was causing headaches which are best sorted out another day.
So the error i receive is:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.app, PID: 12564
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.content.Context.getApplicationContext()' on a null object reference

So this is the relevant code in TManager:
public class TManager extends AppCompatActivity implements Serializable {
BroadcastReceiver sensorReceiver;
BroadcastReceiver locationReceiver;
ExecutorService executorService = Executors.newFixedThreadPool(20);
public static Intent locationIntent;
public static Intent sensorService;
public LocalBroadcastManager localBroadcastManager;
public static MutableLiveData<Integer> status = new MutableLiveData<Integer>();
//Empty constructor
public TManager(){}
#RequiresApi(api = Build.VERSION_CODES.O)
public void startUpdating() {
status.setValue(0);
//register for sensorBroadcast
sensorReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
TCIMUEvent tcimuEvent = (TCIMUEvent) intent.getSerializableExtra("imuevent");
// Log.d(TAG, "In Motion Received "+ tcimuEvent.getTime());
Runnable provideDM = new Runnable() {
#Override
public void run() {
//traceCWrapper.provideDeviceMotion(tcimuEvent, Status, 0, RotationMode.Undetermined);
}
};
executorService.execute(provideDM);
}
};
localBroadcastManager.getInstance(MyApplication.getAppContext()).registerReceiver(
sensorReceiver, new IntentFilter("imuCreated")
);
//register for locationBroadcast
locationReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
TCLocationEvent tcLocationEvent = (TCLocationEvent) intent.getSerializableExtra("locationevent");
Runnable provideLoc = new Runnable() {
#Override
public void run() {
traceCWrapper.provideLocation(tcLocationEvent);
}
};
executorService.execute(provideLoc);
}
};
LocalBroadcastManager.getInstance(context).registerReceiver( //Error Here <-----
locationReceiver, new IntentFilter("locationCreated")
);
isRunning = true;
//Start the Services
AsyncTask as1 = new AsyncTask() {
#Override
protected Object doInBackground(Object[] objects) {
startUpdatingLocation();
return null;
}
}.execute();
AsyncTask as2 = new AsyncTask() {
#Override
protected Object doInBackground(Object[] objects) {
startUpdatingSensors();
return null;
}
}.execute();
}
}
This is just one example i keep getting these errors all through the code which was copied in another example error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.AssetManager android.content.Context.getAssets()' on a null object reference
It seeems to especially be where is use
MyApplication.getAppContext......
MyApplication just returns as below:
public class MyApplication extends Application {
private static Context context;
public void onCreate() {
super.onCreate();
MyApplication.context = getApplicationContext();
}
public static Context getAppContext() {
return MyApplication.context;
}
}
How do i resolve these issues? The whole classes have been moved over it is not code taken from one class dumped into another. So not sure why context should have changed.
As i was using the MyApplication static context class in some places i needed to add this line to my Manifest file within the tag
android:name="com.yourapp.app.yourapp.MyApplication"
and make sure the application class is placed in the top level main/java/com.yourapp.app.yourapp/
This worked for me and solved the issue throughout the App. I would pay attention to the comments made as this may well not be the best way to be using Context, however this solved my issue at the moment.

I had the same error, and did a lot til it worked, however I might not be able to say specifically what fixed it, but its probably not code. My best guess is you need to Verify your Dev Account as Individual or Business Account
https://developers.facebook.com/docs/development/release/individual-verification
As written, the changes take effect immediatetely, so when I got the email that my account was verified successfully, I went to my app, tried the oAuth, it worked.
I'll point out other things I did:
Change public_profile permissions to Advanced
Change email permissions to Advanced
Added all the SHA1 fingerprints used in firebase to facebook dev, after Hex to Base 64, https://base64.guru/converter/encode/hex
Added facebook app id in the manifest, since firebase had its own facebook app id, I used tools:replace="android:value" on that meta data
So whether its all of them or one of them, I encourage you to check the list.

java.lang.IllegalStateException: AssetManager has been finalized

I went to sleep yesterday with my app working and today when I tried to run it won't start at all. As soon as I try to open it crashes with a java.lang.IllegalStateException. I've gone several commits back in my code just to rule out it was something I did recently and still. This makes no sense, how can an app just stop working over night? I've looked for the error in the internet and there is not a lot of useful information about it. Is this really an odd error?
Here's the complete stack trace:

Since like I said it doesn't seem to be anything that I did I'm not sure what code to post. But given that the app crashes on start here's the code for the two main classes that are supposed to start first:
App
public class App extends Application {
private static App instance;
private static final String TAG = "Starter";
#Override
public void onCreate() {
super.onCreate();
instance = this;
// Enable Local Datastore.

//Parse server
Log.d(TAG, "Initializing Parse");
Parse.initialize(new Parse.Configuration.Builder(this)
.applicationId(getString(R.string.parse_app_id))
.clientKey(getString(R.string.parse_client_key))
.server(getString(R.string.server_address)).build()
);
//Facebook
if (AccessToken.getCurrentAccessToken() == null)
ParseFacebookUtils.initialize(this);
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
defaultACL.setPublicReadAccess(true);
defaultACL.setPublicWriteAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
Log.d(TAG, "Parse ready");
}
public static App getInstance(){
return instance;
}
}
SplashActivity
public class SplashActivity extends AppCompatActivity {
private static final String TAG = "Splash";
private boolean firstTime = true;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

startActivity(new Intent(SplashActivity.this, WelcomeActivity.class));
finish();
}
}

}
public boolean isLoggedIn() {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
String parseSession = ParseUser.getCurrentUser().getSessionToken();
return parseSession != null;
}
}
Your stacktrace links to this class in the AOSP.
I think this crash has nothing to do with your app, but as an error in the Launcher class. Try installing from USB debugging and see if that works.
But there are still some details that are blurry. These lines are (from bottom of the stacktrace to the top) the lines that cause problems in com.android.launcher2 package:
https://android.googlesource.com/platform/packages/apps/Launcher2/+/android-4.2.2_r1/src/com/android/launcher2/AppsCustomizePagedView.java#584
https://android.googlesource.com/platform/packages/apps/Launcher2/+/master/src/com/android/launcher2/Launcher.java#2469
https://android.googlesource.com/platform/packages/apps/Launcher2/+/master/src/com/android/launcher2/Launcher.java#2442
From this error, I assume you are using a Nexus or Pixel (or any device with the unaltered source code, meaning stock android.).
From what I can tell from this error, this is not an error related to your app. It appears to be an issue with the launcher you are using. Try installing from USB debugging, or change launcher, and see if that works. Try rebooting your device as well.
Further, from what I see of your code, there are no parcelable classes in use
This error can also be caused when Instant Run loses connection with the Android Emulator as a result of which new app changes are not persisted in the emulator.
Running the app again will solve the issue.

Android Retrofit "Attempt to invoke virtual method on a null object reference"

Hi first of all i searched some similar questions like mine but unfortunately i couldn't find the similarity of my code to them so please here me out
I have a Main Activity Class
public class MainActivity extends AppCompatActivity {
public ProgressDialog loading;
public String[] itemer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RetrofitHandler handler = new RetrofitHandler();
handler.getContacts(MainActivity.this);
}
public void getter(String[] response, int size) {
String[] itemer;
itemer = new String[size];
if (response != null) {
itemer = response;
Toast.makeText(MainActivity.this, itemer[0], Toast.LENGTH_SHORT).show();
}
}
And a Handler for my result
public class RetrofitHandler {
public String[] item;
public static final String ROOT_URL = "http://api.androidhive.info";
public List<Contacts> contacts;
// final MainActivity main = new MainActivity();
public void getContacts(final Context context) {
final ProgressDialog loading = ProgressDialog.show(context, "Fetching Data", "Please wait...", false, false);
RestAdapter adapter = new RestAdapter.Builder().setEndpoint(ROOT_URL).build();
ContactsAPI api = adapter.create(ContactsAPI.class);
api.getContacts(new Callback<Contacts>() {
#Override
public void success(Contacts contacts, Response response) {
loading.dismiss();
MainActivity update = new MainActivity();
List<Contact> contactList = contacts.getContacts();
item = new String[contactList.size()];
int size = contactList.size();
for (int i = 0; i < contactList.size(); i++) {
item[i] = contactList.get(i).getName();
}
update.getter(item, size);
}
#Override
public void failure(RetrofitError error) {
Toast.makeText(context, "Error Occured", Toast.LENGTH_LONG).show();
}
});
}
But I get an error on my response in the main activity here is my log

I maked sure that the handler item where not null tested it with toast but when i pass it to getter it gives me the error where did i do wrong? :(
MainActivity update = new MainActivity();
Never instantiate activities with new. They are not initialized to be useful.
Instead, you can pass your activity as a reference where needed. Change
public void getContacts(final Context context)
to e.g.
public void getContacts(final MainActivity mainActivity)
and use mainActivity where you need an activity Context (such as with Dialogs) and when you need to invoke a method on MainActivity.
Note that generally passing activity references to async operations can be prone to significant memory leaks, and you need to take activity lifecycle into account - the activity might not be active when the async operation finishes.
try to delete the toast in your main activity or replace Mainactivity.this to getApplicationContext() .
from :
Toast.makeText(MainActivity.this, itemer[0], Toast.LENGTH_SHORT).show();
to :
Toast.makeText(getApplicationContext(), itemer[0], Toast.LENGTH_SHORT).show();

java.lang.NullPointerException in Admob while showing Rewarded Video

In Android,When I tried to load the Ad in Admob and there is no internet connection the code reaches onRewardedVideoAdFailedToLoad() and after sometime say 30 sec the app force closes with the below mentioned error.
I hope this is not the null pointer exception that I can handle. It is happening in the SDK I guess. Please let me know how to resolve this.
Code
private void setRewardedVideo() {
rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
rewardedVideoAd.setUserId(REWARD);
AdRequest adRequest = new AdRequest.Builder().build();
rewardedVideoAd.loadAd(AD_UNIT_ID_REWARDED_VIDEO_AD, adRequest);
rewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
#Override
public void onRewardedVideoAdLoaded() {
System.out.println("onRewardedVideoAdLoaded()");
if (rewardedVideoAd.isLoaded()) {
rewardedVideoAd.show();
}
}
#Override
public void onRewardedVideoAdOpened() {
System.out.println("onRewardedVideoAdOpened()");
}
#Override
public void onRewardedVideoStarted() {

Ensure the user has connectivity before even trying to load the ads, there may be some deeper issue with AdMob that forces this NPE despite no internet.
private void setRewardedVideo() {
if (!isNetworkAvailable()) {
// Log no internet
return;
}
rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
rewardedVideoAd.setUserId(REWARD);
....
}
It may even make sense to ensure user has internet before trying to use adMob incase it is something with their library that is causing the issue. See this answer for that.
