I am trying to convert Parse to Clevertap in the application I'm working on. I have tried looking at https://blog.clevertap.com/transitioning-from-parse-push-notifications/ but haven't had much luck on what I'm trying to accomplish.
In the method that needs to be converted, I am wanting the user to have the ability to subscribe and unsubscribe from a channel using:
private class AllPushClickListener implements View.OnClickListener {
private AppFeed mAppFeed;
public AllPushClickListener(AppFeed appFeed) {
mAppFeed = appFeed;
}
#Override
public void onClick(View v) {
Log.d(TAG, "subscribing to " + getPushChannelName(mAppFeed) + "_all");
ParsePush.unsubscribeInBackground(getPushChannelName(mAppFeed) + "_top");
ParsePush.subscribeInBackground(getPushChannelName(mAppFeed) + "_all");
mAppFeed.setPushNotificationsOn(true);
mAppFeed.setReceiveTopNotifications(false);
mAppFeed.setChannelName(getPushChannelName(mAppFeed) + "_all");
hideNotificationButtons();
mPushAllStoriesSelectedButton.setVisibility(View.VISIBLE);
mPersistedFeedDaoHelper.createOrUpdate(mAppFeed);
}
}
Not sure how to transition this into Clevertap.
Thanks for the help.
You can find the Parse migration guide here - https://github.com/CleverTap/parse-migrate and, channels is discussed here - https://github.com/CleverTap/parse-migrate#managing-channels. Do write to support#clevertap.com if you need more help, or have any questions.

So I was wondering if I send an Embed for something with my Bot, can I edit it with the Bot afterwards?
If that's possible, then show me how to do it please.
This is my Code that I`ve got so far, but idk how to edit that EmbedBuilder afterwards:
public class Giveaway extends ListenerAdapter {
#Override
public void onMessageReceived(MessageReceivedEvent event) {
if (event.getMessage().getContentDisplay().startsWith("+giveaway")) {
if (event.getMessage().getContentDisplay().substring(10, 11) != null) {
long msgid = event.getMessageIdLong();
String count = event.getMessage().getContentDisplay().substring(10, 11);
EmbedBuilder eb = new EmbedBuilder();
eb.setTitle("It's GIVEAWAY-TIME!");
eb.setDescription("Prize: " + "\n Winners: " + count);
eb.setColor(Color.BLUE);
event.getTextChannel().sendMessage(eb.build()).queue();
}
}
}
}
So to be clear, what I want to do is add a footer to the message afterwards and change the description in some cases.
I have tried some things but I've not come up with a solution yet.
Would be nice if you answer.
Kind regards,
lxxrxtz
You can keep the embed builder and create a new embed:
eb.setFooter(...);
MessageEmbed embed = eb.build();
Then all you have to do is call message.editMessage(embed).queue() with the message you want to edit. You can access the message from the callback in your sendMessage:
channel.sendMessage(embed).queue(message -> {
eb.setFooter(...);
message.editMessage(eb.build()).queue();
});
I'm trying to create an app that only adds an entry to the database if there is no entry already at a specific time intervals and modifies the existing entry if there is already one in the database. I'm using Room.
It works, but only with a workaroud, because I have to call the add function twice before the value gets added (make the input two times before it works). And I also don't like my adding the Observer and immediately removing it afterwards. I also had to implement the workaround when instatiating the DB, with a value when it was first created.
How can I get the data from my LiveData List inside the Repository class and change it without ending up in an endless loop or how do I have to redesign my code to avoid that?
The complete code can be found on my Github account: Github repository
I would really appreciate any suggestion fix my problem and learn to design and plan my code better.
MainActivity
public void ok_clicked(View view) {
Intent intent = new Intent(this, DataActivity.class);
...
Diary addDiary = new Diary(new Date(), diaryCh.isChecked(), readingCh.isChecked(),writingCh.isChecked(),pianoCh.isChecked(),youtubeCh.isChecked());
mDiaryViewModel.insert(addDiary);
startActivity(intent);
}
DiaryViewModel
public void insert(Diary diary) {mRepositroy.add(diary);}
DiaryRepository
public class DiaryRepository {
private DiaryDao mDiaryDao;
private LiveData<List<Diary>> mEntriesToday;
DiaryRepository(Application application) {
AppDatabase db = AppDatabase.getDatabase(application);
mDiaryDao = db.diaryDao();
mEntriesToday = mDiaryDao.findEntriesByDate(Dates.getYesterdayMidnight(), Dates.getTomdayMidnight());
}
LiveData<List<Diary>> getmEntriesToday() { return mEntriesToday;}
void add(Diary diary) {
Observer<List<Diary>> observerEntriesToday = new Observer<List<Diary>>() {
#Override
public void onChanged(List<Diary> diaries) {
if (diaries != null) {
Log.e(TAG, "add: with matching entries"+ diaries.get(0) + " add: " + diary );
diaries.get(0).addAttributes(diary);
new updateDiaryAsyncTask(mDiaryDao).execute(diaries.get(0));
} else {
Log.e(TAG, "add: without matching entries"+" add: " + diary );
new insertDiaryAsyncTask(mDiaryDao).execute(diary);
}
}
};
getmEntriesToday().observeForever(observerEntriesToday);
getmEntriesToday().removeObserver(observerEntriesToday);
}
You shouldn't be using LiveData in this scenario at all. It is only a wrapper for data that will be observed from Activity/Fragment.
First you need to modify mEntriesToday to be MutableLiveData so you can update it.
In your case, you can omit using Observer for updating DB, and so something simple like:
void add(Diary diary){
if (mEntriesToday.getValue() != null) {
Log.e(TAG, "add: with matching entries"+ mEntriesToday.getValue().get(0) + " add: " + diary );
mEntriesToday.getValue().get(0).addAttributes(diary);
new updateDiaryAsyncTask(mDiaryDao).execute(mEntriesToday.getValue().get(0));
} else {
Log.e(TAG, "add: without matching entries"+" add: " + diary );
new insertDiaryAsyncTask(mDiaryDao).execute(diary);
}
}
If you need this data, outside this class, then you can use getmEntriesToday() and observe it.
You can get the value of the LiveData using the getValue() method
void add(Diary diary) {
List<Diary> diaries = mEntriesToday.getValue();
if(diaries!=null){
diaries.get(0).addAttributes(diary);
//update
}else{
//insert
}
I have a mp4 file(already recorded) and want to change the rotation(including meta data) of the video. There is a way to do this using Hex Editor where in you find the track header(tkhdr) and replace the rotation matrix with the required rotation.
I know this can be done using ffmpeg library but I do not want to use the library instead I want to do this in Android using JAVA. Let me know if anyone has done this before.
Thanks
Ravi

This library may help you: https://github.com/MasayukiSuda/Mp4Composer-android
This library generates an Mp4 movie using Android MediaCodec API and can rotate Mp4.
StackOverflow reference: https://stackoverflow.com/a/19392712/8572503
It's API is fluent and easy :
new Mp4Composer(sourceFile, destinationFile)
.rotation(Rotation.ROTATION_90)
.size(1280,720) //720P
.fillMode(FillMode.PRESERVE_ASPECT_FIT)
.listener(new Mp4Composer.Listener() {
#Override
public void onProgress(double progress) {
Log.d(TAG, "onProgress = " + progress);
//or show in notification
}
#Override
public void onCompleted() {
Log.v(TAG, "onCompleted() : Destination → "+ destinationFile);
}
#Override
public void onCanceled() {
Log.d(TAG, "onCanceled");
}
#Override
public void onFailed(Exception exception) {
Log.wtf(TAG, "onFailed()", exception);
}
})
.start();

[EDIT: From Comment]:
You can extract code from this: https://github.com/javadev/hexeditor to manually modify the hex.
Due to the breaking changes in Android WebRTC client's example, I'm looking for the code-example which shows how to add and work with DataChannel in Android. I need to just send "Hello Worlds" via DataChannel between 2 Android devices. Here's the old code:
https://chromium.googlesource.com/external/webrtc/stable/talk/+/master/examples/android/src/org/appspot/apprtc/AppRTCDemoActivity.java#177
It uses some classes and interfaces which don't exist in the new version anymore.
So how can I add support of DataChannel to my Android WebRTC application, send and receive a text through it?
I added DataChannel in a project with an older version of webrtc. I looked at the most up to date classes and it seems the methods and callbacks are still there, so hopefully it will work for you.
Changes to PeerConnectionClient:
Create DataChannel in createPeerConnectionInternal after isInitiator = false;:
DataChannel.Init dcInit = new DataChannel.Init();
dcInit.id = 1;
dataChannel = pc.createDataChannel("1", dcInit);;
dataChannel.registerObserver(new DcObserver());
Changes to onDataChannel:
#Override
public void onDataChannel(final DataChannel dc) {
Log.d(TAG, "onDataChannel");
executor.execute(new Runnable() {
#Override
public void run() {
dataChannel = dc;
String channelName = dataChannel.label();
dataChannel.registerObserver(new DcObserver());
}
});
}
Add the channel observer:
private class DcObserver implements DataChannel.Observer {
#Override
public void onMessage(final DataChannel.Buffer buffer) {
ByteBuffer data = buffer.data;
byte[] bytes = new byte[data.remaining()];
data.get(bytes);
final String command = new String(bytes);
executor.execute(new Runnable() {
public void run() {
events.onReceivedData(command);
}
});
}
#Override
public void onStateChange() {
Log.d(TAG, "DataChannel: onStateChange: " + dataChannel.state());
}
}
I added onReceivedDataevents to PeerConnectionEvents interface and all the events are implemented in the CallActivity so I handle the data received on the channel from there.
To send data, from CallActivity:
public void sendData(final String data) {
ByteBuffer buffer = ByteBuffer.wrap(data.getBytes());
peerConnectionClient.getPCDataChannel().send(new DataChannel.Buffer(buffer, false));
}
I only took a quick look at the new classes and made minor changes to my code, I hope it will work for you with no more changes.
Good luck
I'm sorry that I have a question to the code from Guy S.
In your code, there are two following statements in both createPeerConnectionInternal() and onDataChannel().
dataChannel.registerObserver(new DcObserver());
I think it may cause twice registrations. Is it correct??
I mean, before making a call, it created a dataChannal and registered an Observer. Then.. if there is a call comes in, the onDataChannel called, then the dataChannel point to dc and register again??
I need to extract audio from a live stream on red5 and stream it separately. On nginx with rtmp module I'd just retranslate this stream via ffmpeg without videodata, but I have no idea how to do anything like this (with or without ffmpeg) on Red5.
The first link on google gave me this:
just register IStreamListeners on your IClientStreams, and then separate AudioData from VideoData in the RTMPEvents
But this doesn't help much. To be honest, this doesn't help at all. What are these IStreamListeners and how do I register them on IClientStream?
And, what is more misterious, how do I separate AudioData from VideoData in some RTMPEvents?
This is how your extend RTMPClient and capture the Audio or Video events
private class TestClient extends RTMPClient {
private int audioCounter;
private int videoCounter;
public void connect() {
private IEventDispatcher streamEventDispatcher = new IEventDispatcher() {
public void dispatchEvent(IEvent event) {
System.out.println("ClientStream.dispachEvent()" + event.toString());
String evt = event.toString();
if (evt.indexOf("Audio") >= 0) {
audioCounter++;
} else if (evt.indexOf("Video") >= 0) {
videoCounter++;
}
}
};
}
}
This simply counts the a/v events, but it will get you part of the way there. I suggest looking though the unit tests in red5 and there you can learn a lot.
