You need to add this dependency:
implementation "com.github.parse-community.Parse-SDK-Android:parse:1.24.2"

Android Studio Sync fails due "failure to parse XML in AndroidManifest.xml"

I decided to update an old app, sadly when I try to sync the project I'm getting the following Gradle Sync error:
"ERROR: Failed to parse XML in C:...\app\src\main\AndroidManifest.xml
ParseError at [row,col]:[17,9]
Message: expected start or end tag
Affected Modules: app"
After doing my research and forums, the problem seems to be in the AndroidManifest (duh!) when I go to the line 17 I find the Meta-data of my app, and if I add some lines before this, the error moves accordingly to the line.
I have also updated the Gradle to 4.10.1, the Android Plugin version is 3.3.1; and I'm using the "Default Gradle Wrapper"

I'll appreciate if someone could point me in the right direction as I seem to be missing some tags in my manifest and at this point I don;t know what I'm doing wrong here :(
Thank you all before hand for your help! :)

Remove below line from your manifest.xml file
///META DATA
And replace it with below comments syntax
<!—- META DATA —->

As pointed out here already to comment in XML we shouldn't be using /// but <!-- > instead.
Please replace /// META DATA with <!-- META DATA-> and that should work.

If you want to make comment in xml file, you need to use <!--your comment here--> this tag. // or /**/ doesn't work

I also faced the same issue, where removing the comments from
//this is a comment
to
<!--this is a comment-->
worked for me.

Firebase Push Notification will not be shown

I finally start to experiment with Firebase Cloud Messaging Service in Android Studio. I try this tutorial and I have exactly the same classes like in this tutorial:
enter link description here
My first Question is, why did the "Android Monitor" in Android Studio, show me the device token only one time? Everytime I start a new Project in Firebase and connect it with my AppProjekt and run it, the Token just showed me the first time when I run the project without troubles. If I run it again, I don't see anything of this Token, nothing!
Second Question is, why I don't get the Push Notification from Firebase?
Here is my Android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.felixkoepping.pushtest2">

The only "red Message" in Android Monitor is:
E/FA: Failed to send event to AppMeasurementService:
android.os.DeadObjectException:
com.google.android.gms.measurement.internal.zzm$zza$zza.zza(Unknown Source)
If I send a notification from the Console in Firebase to exactly this Device with the Token, nothing will be shown in my Emulator...
I hope some of you guys can help me with this Problem. I tried so much, but nothing works...
Thanks Guys :-)

thanks for writing in. I'll be helping today to get your problem resolved.
The notification sent from the console will show up only when the app is closed or in it's background state.
To make the app show notifications in the foreground state, refer to this link Firebase notifications in the foreground
If you're still unaware of what happens, ping me through the comment facility, thanks!

Git submodule causing Failure [INSTALL_FAILED_OLDER_SDK] Android sdk 21

I am working on an app and trying to use the new material design, aka sdk version 21.
I had everything working fine, and then wanted to at a fab (floating action button) using this library.
I added this library as a submodule, using
git submodule add https://github.com/shamanland/floating-action-button
while under C:\Users\USER\AndroidStudioProjects\ProjectName
My file structure looks like so
ProjectName
app
floating-action-button
The issue
Before everything was totally fine, I was able to build and run the project.
But, ever since adding this submodule, when trying to run it, I get the error
Failure [INSTALL_FAILED_OLDER_SDK]
So I'm thinking it has to do with the submodule, but I'm not sure how.

I have a strong suspicion that the submodule was added incorrectly.
Really all I want is to use a fab in my app, if anyone can help me figure out what may be wrong, with adding the submodule, or something with my build.gradle, that would really be appreciated!!

This error is usually caused by deploying an APK built with "compileSdkVersion n" to a device or emulator with an API level less than "n". Is your emulator at the right API level?
