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.

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.

Rendering Problems
"high_quality" in attribute "breakStrategy" is not a valid integer
([N] similar errors not shown)
Tip: Try to refresh the layout.
([N] is a variable number.)
This message was produced after I restarted Android Studio, for all activities and any other design-able files (such xml/pref_XXX.xml files)!
I searched all project files (Ctrl+Shift+F) for "high_quality" and "breakStrategy" but found nothing!
The interesting note is no problem in designing! Just show this message.
Also, I tried Clean Project, Rebuild Project, Synchronize (Ctrl+Alt+Y), Synchronize app, pressing the refresh hyperlink inside the mentioned message, restarting Android Studio again, ... But no avail!
I have updated the android sdk build-tools, platfom-tools, API 25 and works.
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.
So I want to build an extensible android application where developers can add 'CustomDevice' classes and the main program will run them automatically without editing existing code.
I've read about Service Provider interface and thought that would be a nice way to go about it.
So I tested it and created an interface called 'ICustomDevice' which custom device classes are expected to implement.
I've created a class called 'DummyDevice' that implements ICustomDevice.
Both DummyDevice and ICustomDevice are in the same package "CustomDevicePackage".
So in my main program I run the following.
ServiceLoader<ICustomDevice> loader = ServiceLoader.load(ICustomDevice.class);
Iterator<ICustomDevice> devices = loader.iterator();
System.out.println("Does it have devices? " + devices.hasNext());
It always returns false, which means it's not finding the 'DummyDevice'
In my eclipse project I created a folder at 'src' called META-INF and under it, a subfolder called 'services'.
'Services' has a file named 'CustomDevicePackage.ICustomDevice' with a line of content 'CustomDevicePackage.DummyDevice'.
Am I doing it right? Every example I see about SPI is about loading JARS.
I'm not loading a JAR, I'm trying to run a class in the same Project. Does this method only works for loading JARs? I want my program to support loading local subclasses and external JARs alike.
I am adding this as an answer but leaving the prior "answer" to provide extended code detail for this workaround. I am working on reporting the prior answer results as a bug to Google.
Because the Android implementation of java.util.ServiceLoader is broken (always populating internal java.security.AccessControlContext field with AccessController.getContext() even if System.getSecurityManager() == null), the workaround is to create your own ServiceLoader class by copying the code found at OpenJDK for Java 8 into your class, add specific imports required from java.util without using import java.util.*;, and call that ServiceLoader in your code (you will have to fully reference the ServiceLoader you created to over ambiguity).
This isn't elegant but it is a functional workaround that works! Also, you will need to use a ClassLoader in your ServiceLoader.load() call. That ClassLoader will either have to be YourClass.class.getClassLoader() or a child ClassLoader of the class' ClassLoader.
Though it's an old post, This may be still be of some help to others:
When I was running or debugging a project that contained a ServiceLoader Class, I had to put the META-INF/services folder into the src/ folder in Eclipse.
If I tried to export the project as Runnable jar and tried to use the class with the service loader, it never worked.
When I checked the jar, unzipping it, I found the folder under src/META-INF/services though.
Only when I also added the META-INF folder directly in the root directory of the jar, it started to work.
I haven't found a fix though inside Eclipse, that makes sure it gets exported right...maybe an ANT script can solve this issue, but so far no attempts made...
This is an answer:
At some point, Android removed the AccessControlContext field in ServiceLoader and ServiceLoader now works. As my comments indicate, this was reproduceable using the "out-of-the-box" OREO (API 26) Intel Atom x86 emulator with Android Studio (also fresh download). 24 hours later, ServiceLoader no longer contained the acc field (as shown in the Android Studio debugger with the same emulator). The Android SDKs dating back to API 24 do not show the acc field.
Per the Android developer currently maintaining the ServiceLoader code:
He is not aware of ServiceLoader ever having the acc field in Android (it did as we were able to reproduce) and thought the debugger/emulator might have been using JDK code (but I showed the OpenJDK code works correctly). Somewhere along the way, the errant code was updated and I am no longer able to reproduce.
Be sure your OS is up-to-date and you should no longer see this phenomena.
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.
