I am trying to run the default app which comes when creating a flutter file using "flutter run" but it gives me the following error:The error I am facing.
I did try installing gradle, creating a settings.gradle file in my root directory of project and run "gradle wrapper" it was successful but I still face the same error.
UPDATE: One of my parent directories had spaces in the directory name. After removing the spaces it solved the issue.
Your gradle-wrapper is missing. Make sure that you've a gradle distribution added in your PATH variable and restore the wrapper by running this command:
gradle wrapper
i am installing Android Api 19 but when i create the Android appliction this generates the follwing errors. Android is installad on windows 7.plz help me solving these errors of "Build path" i have updated the tools but these errors still occuring.

After the import step on this page: http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html#import-opencv-library-and-samples-to-the-eclipse
I keep getting the following errors like in a popup in Eclipse:
Building workspace: Errors occurred during the build. Errors running

#OPENCV_VERSION#'. java.lang.NullPointerException Errors running

not exist. I followed the warning and note given at the bottom as
well, but that did help.
My OpenCV4Android SDK version is 2.4.9.
I ran into the same problem -- I didn't wind up needing to switch to OpenCV4Android 2.4.8, but deleting my 2.4.9 directory and re-unzipping it and going through the steps from scratch seemed to fix everything. I'm sure I just corrupted some files, and re-extracting my SDK fixed it.
So long story short:
Make sure you follow EVERY step in the tutorial:
http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html
Make SURE that when you import the sample projects that you do it from the ROOT of the SDK directory -- not from the sample directory -- otherwise you miss the library.
Make SURE that you don't extract your OpenCV directory into a directory with spaces in the path (such as "My Documents").
And if you're wrestling it with a while and you can't seem to get it working, then don't hesitate to quit eclipse, delete your workspace, delete your OpenCV directory, and re-extract from the downloaded zip file and try again.
I had the same frustrating problem, I had to do two steps (different again!):
Open Properties for the Open CV library project (mine was OpenCV Library - 2.4.10), go to Android -> Project Build Target, and select a target name. (This is mentioned in the tutorial.)
Still in the Properties dialog, go to Java Build Path -> Source, at the bottom where it says Default output folder: mine said "OpenCV Library - 2.4.10/cls" - I changed this to "OpenCV Library - 2.4.10/bin"
And now it's building without errors.
I did both of the following together:
Set NDKROOT for all projects individually even though the environment variable existed in my bashrc.
Switched to OpenCV4Android SDK version 2.4.8
As soon as I finish importing the android support library project into my workspace (I am using eclipse ide), I receive this error message:
Could not not write to file: C:\Program Files\extras\android\support\v7\appcompat\bin
The library project appears in my workspace, however if i try a clean build:
Errors occurred during the build. Errors running builder 'Android
Package Builder' on project 'android-support-v7-appcompat'. Resource
'/android-support-v7-appcompat/bin' does not exist.
Here is the stack trace:
[2013-12-17 18:11:20 - android-support-v7-appcompat] Android requires
compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use
Android Tools > Fix Project Properties.
The error log also states that bin folder does not exist/cannot be written to.
Here are things I have tried so far and failed:
1. Clean build
2. Install then re install
3. Fix android properties.
I have not used any of the API from the support library.
Open the project properties in Eclipse. Choose Java Compiler and make sure the Compiler Compliance level is set to 1.5 or 1.6.
I keep getting a generic error when I try to create an Android project using the m2e-android plugins. I follow the basic steps here:
http://rgladwell.github.io/m2e-android/
using version Archetype version 1.0.11, but each time I find that my project has an error of some sort. The project folder in Eclipse has an exclamation point on it, which I think indicates a build path error, but I have no idea where the problem lies. When I try to clean the project I get the error:
Errors occurred during the build.
Errors running builder 'Android Pre Compiler' on project 'LookAroundYou'.
java.lang.NullPointerException
Errors running builder 'Android Pre Compiler' on project 'MainActivity'.
java.lang.NullPointerException
I have read about this error but almost every solution I have found indicates it is a problem with SVN, but I am not using SVN.
