Android: Gradle Error in Android Studio - android

I recently added some .gifs to my /drawable so that I can use them with buttons. This worked fine (no errors). Now, when I go to rebuild/run my application, I get the following error:
Error: Gradle: Execution failed for task ':MyProject:mergeDebugResources'. > Index: 0
I'm not sure how to fix this (and there appears to be no other similar issues that I could find online.
Edit: Now it's the same error, but it also says (at the end of the first error)
Running /Applications/Android Studio.app/sdk/build-tools/android-4.2.2/aapt failed. See output

Okay, I fixed the issue. It was quite weird.
A) I had some capital letters in my res/drawables folder. Not too weird -- I can see how that would remove the first error.
B) Then, however, a lot of values in my main activity file became undefined. I had to manually import 'com.myapp.R'. Now that was weird.
Fortunately, everything is now working.
I hope that if anyone gets the same errors as me, that this response can help them.

(Build failed 'Xcodes output') The getter 'onChanged00' isn't defined for the class 'OTPTextField

I haven't worked on my app for 2 days and all of a sudden, when running the app, I get this error:
debug console
I haven't touched the code and it was working fine 2 days ago.
The links in the error...
otp_field file
otp_field file
...point to the otp_field.dart file(which I never opened), with the error being The getter 'onChanged00' isn't defined for the class 'OTPTextField'.
I'm not sure how this happened and can't seem to solve this. I updated the otp_field entry in the pubspec.yaml file, but this did not work either.
pubspec.yaml file
(This also happens when I run using the android emulator)
What am I missing here? Would be great if you could point me in the right direction. Thanks in advance.

java.lang.NullPointerException when dataBinding enabled = true

Whenever I enable this in my app gradle
dataBinding {
enabled = true
}
and then sync -> It completely succeed.
but when I "run" it, It builds fail and shows this error
java.lang.NullPointerException
at android.databinding.tool.store.LayoutFileParser.parseOriginalXml(LayoutFileParser.java:135)
at android.databinding.tool.store.LayoutFileParser.parseXml(LayoutFileParser.java:93)
...
my app has little amount of Kotlin code, and android version is 3.5, minSdkVersion 19, targetSdkVersion 28, and upgraded to androidX
How can I solve this? which part should I search for solve this problem???
except above code, every thing works perfect.
Edit
And when I rolled back my code before upgrading to androidX and compiled it, it also shows "Null point exception" and at this time, there are no extra message without just "Null point exception".
Finally I got answer. (cc. android databinding error:Execution failed for task ':app:dataBindingProcessLayoutsDebug')
I guessed it was because of BOM. Someone said it will happen when the code is used in two different circumstances(Window and Mac).
So in 'res' folder, I clicked 'remove BOM' button in android studio and that action changed some xml files.
<?xml version="1.0" encoding="utf-8"?>
But it wasn't worked in Mac. This solution worked only in Window.
I tried a little too much but I figured it out. I created the project on the Mac computer and it wasn't a problem when I switched to windows later. When I tried to create a new file, I got this error and just understood why. Every time I right-clicked on the file I just added, I saw an option called "remove BOM". Clicking this solved my problem. But I did not find the solution to the problem logically, I just found it random.

Error building openframeworks for android: “ invalid use of incomplete type ‘class Poco::Path’”

I am trying to build an android application with OF. The application runs in two other computers. However, it does not work on mine. I am using a mac.
I run the command "make AndroidDebug" in the project folder, and this is the error I have:
/Library/openFrameworks/addons/ofxHTTP/libs/ofxHTTP/src/PostRouteFileHandler.cpp:98:46: error: invalid use of incomplete type 'class Poco::Path'
ss << Poco::Path(formFileName).getExtension();
I have installed poco, but nothing changes afterwards.
What can I do to solve this?
Thanks
Have you included Poco/Path.h?
A forward declaration might appeared earlier (possibly in another header) without complete definition.

Issue with projectfolder called (AndroidProjects)?

I have a wired issue. If i set up a folder called AndroidProjects and put my project in there... Android-Studio fails with gradle.
one error is:
IllegalStateException:
PsiFile not parsed for file D:/AndroidProjects/MyApplication/settings.gradle.
Wait until onPsiFileAvailable() is called.
sometimes it says that gradle has a fatal error....
if i set up my projectlocation to e.g. andropro everyting is working fine.
My thoughts:
may problems with 2 big letters in projectfoldername
may foldername is to long
may android or project are registered words in android-studio
Is there a knowen issue using foldernames like i did above?
couldn't find anything on the net.

why am I getting the error "error executing aapt "

I'm getting the error executing aapt :return code 1073741819 due to which
.apk file is not generated how to fix this. How to fix if r.java file is missing
It could be a syntax or formatting error in one of the XML files. I just got this error code (it's actually negative), and I checked all the #string references and they were OK. Eventually I figured out it was because of this item in a menu XML file:
<item
android:id="#+id/action_stop"
android:orderInCategory="100"
android:icon="#drawable/ic_action_stop"
android:showAsAction="ifRoom | withText"
android:title="#string/action_stop"/>
However, the spaces around the | apparently aren't valid (XML isn't Java...). Eclipse didn't catch it as an error, but aapt crashed without giving a reason when it saw it. Not particularly graceful handling, by both Eclipse and aapt. Removing the extra spaces made everything work.
The problem with missing entries in strings.xml apparently produces error code -1073741816, not -1073741819. You have to look closely, but the last digit is different.
I'm not saying the problem is definitely some sort of syntax error. But it's another possibility that could be investigated.
I got this error when I had deleted a #string entry that was being referenced in a menu node xml resource.
I had this error and spent time trying to find a solution.
Finally the solution for this error which is: -1073741819 ( check the digits ) was a library was missing from: Properties -> Android -> Library
I just added the missing libraries and got this error resolved.
I got the same problem. What helped me was changing the Project Build Target
Properties->Android->Project Build Target
