This is my Subscriber from MainActivity.
#Subscribe(sticky = true )
public void eventMessage(YuriActionMessage message){
if (message.getAction() == "LOAD_PLAYER_UI") {
load_ExoPlayerUI();
} else if (message.getAction() == "LOAD_PLAYER_UI_PLAYPAUSE") {
load_PlayPauseBtn();
} else if (message.getAction() == "SET_CURRENT_VIEWPAGER_ITEM_DETAILFRAG") {
mact_IzoneVIewPager.setCurrentItem(5);
//EventBus.getDefault().removeStickyEvent(true);
} else if (message.getAction() == "SET_CURRENT_VIEWPAGER_ITEM_ALBUMFRAG") {
mact_IzoneVIewPager.setCurrentItem(1);
//EventBus.getDefault().removeStickyEvent(true);
}
}
This is the postEvent in my Fragment Attatch from MainActivity
public void initTrackModelList(long albumid){
IzoneGetTracksByAlbum izoneGetTracksByAlbum=new IzoneGetTracksByAlbum(this.getActivity(),albumid){
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
initRecyclerView();
EventBus.getDefault().postSticky(new YuriActionMessage("SET_CURRENT_VIEWPAGER_ITEM_DETAILFRAG"));
}
};
izoneGetTracksByAlbum.execute(mTrackModel);
}
this is my Event Message Model.
public class YuriActionMessage {
private String Action;
public YuriActionMessage(String action){
this.Action=action;
}
public String getAction() {
return Action;
}
public void setAction(String action) {
Action = action;
}
}

It's not about Eventbus. Sometimes errors in your code are thrown as Eventbus exceptions. Check your code. For example:
mact_IzoneVIewPager.setCurrentItem(5);

I got a super weird crash on Fabric onResume of my FragmentActivity, at the super.onResume()

What does this mean, and can be fixed somehow?
Not crashing in my code, but in the super of the FragmentActivity, I can't figure out what I am doing wrong:

This is my onResume():
#Override
protected void onResume() {
super.onResume();
registerReceiver(addedPitstopBroadcastReceiver,
new IntentFilter("addedPitstop"));
if (PSApplicationClass.getInstance().pref.getUserId(PSTimelineFragmentsActivity.this) != null) {
renewSettings();
PSApplicationClass.getInstance().pref.setIsBackground(this, false);
if (PSApplicationClass.getInstance().pref.isRefetchUser(PSTimelineFragmentsActivity.this)) {
PSApplicationClass.getInstance().pref.setRefetchUser(PSTimelineFragmentsActivity.this, false);
MyFirebaseInstanceIDService.changeFirebaseToken(PSTimelineFragmentsActivity.this);
}
}
}
But it directly crashed at onResume, so it didn't pass to the next line. Also tried to reproduce me, but could not.

i will try this method https://stackoverflow.com/a/49959522/6477998 but still throw this error.
my gradle is..
dependencies {
implementation('com.mopub:mopub-sdk-interstitial:5.0.0#aar') {
transitive = true
}
// For rewarded videos. This will automatically also include interstitials
implementation('com.mopub:mopub-sdk-rewardedvideo:5.0.0#aar') {
transitive = true
}
implementation 'com.google.firebase:firebase-core:16.0.0'
implementation 'com.google.firebase:firebase-ads:15.0.1'
}
Which one to change, please give me a solution, am searching still 3 days but no improvement.
Advance thanx...

thanks, the error will be fixed after long time.
Step 1: i remove my adapter class GooglePlayServicesRewardedVideo.java from com.mopub.mobileads( if you are using GooglePlayServicesInterstitial.java please remove ).
Step 2: then, put admob mediation sdk into build.gradle i.e implementation 'com.mopub.mediation:admob:15.0.0.8'.
Step 3: then, remove the following lines in your rewarded display activity.
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MoPubRewardedVideos.initializeRewardedVideo(this);
MoPub.onCreate(this); // remove
// ...
}
#Override
public void onPause() {
super.onPause();
MoPub.onPause(this); // remove
}
#Override
public void onResume() {
super.onResume();
MoPub.onResume(this); // remove
}
// The following methods are required for Chartboost rewarded video mediation
#Override
public void onStart() {
super.onStart();
MoPub.onStart(this); // remove
}
#Override
public void onRestart() {
super.onRestart();
MoPub.onRestart(this); // remove
}
#Override
public void onStop() {
super.onStop();
MoPub.onStop(this); // remove
}
#Override
public void onDestroy() {
super.onDestroy();
MoPub.onDestroy(this); // remove
}
#Override
public void onBackPressed() {
super.onBackPressed();
MoPub.onBackPressed(this); // remove
}
}
Step 4 : syn your project, and take a build. Its working fine without error.
thanks.

App Crash while connecting to Salesforce live agent chat in Android

We are implementing the salesforce live agent chat in our android mobile application. Everything works fine. But we have a corner case.
Initiating the chat -> Opens chat window -> click on close button in window immediately [ within fraction of second ]. App will be crashed. Below is the log obtained from crash.

Is there any work around to overcome this issue. Help is appreciated.

This is how I'm doing it on my end. Hope this helps.

OnErrorNotImplementedException somehow still being called with included error handling

Im performing a write to a BLE characteristic, where with these specific devices certain characteristics are not writeable if the peripheral is still locked.
I'd like to simply provide a visual notification if this is called while the device is still locked, instead of the exception being thrown.
Here is the first part of the code which is from a custom library I've written for this application:
public Observable<byte[]> setInterval(int interval) {
if (!(interval > 0)) {
return Observable.error(new IllegalArgumentException("Interval must be greater than 0."));
}
byte[] bytes = Utils.formatIntToBytes(interval);
return mConnection.writeCharacteristic(Constants.INTERVAL, bytes)
.doOnError(throwable -> Log.d(TAG, "call: Error writing to the interval characteristic"))
.onErrorReturn(throwable -> {
return new byte[0];
});
}
And here is the method that uses the previous:
private void setInterval(int interval) {
mDevice.setInterval(interval)
.onErrorResumeNext(throwable -> {
return Observable.empty();
})
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<byte[]>() {
#Override
public void onCompleted() {
}
#Override
public void onError(Throwable e) {
e.printStackTrace();
}
#Override
public void onNext(byte[] bytes) {
if (bytes != null) {
Toast.makeText(DeviceDetailActivity.this, Utils.formatResponse(bytes), Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(DeviceDetailActivity.this, "Seems to of been an error. Ensure the device is unlocked.", Toast.LENGTH_SHORT).show();
}
}
});
}
This was previously just an Action1, but I changed to a Subscriber to clearly show onError() has been implemented.
I've added a bunch of extra operators (onErrorReturn(), onErrorResumeNext()) in an attempt to prevent the exception.
Why is the exception still coming through?
