Failed to crunch file - Android studio (app:mergeDebugResources)

问题

i am currentyl trying to implement Google ActivityRecognitionApi. However i get following errors:

Error:Failed to crunch file C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject\app\build\intermediates\exploded-aar\com.google.android.gms\play-services-cast-framework\10.0.1\res\drawable-xxhdpi-v4\quantum_ic_forward_30_grey600_36.png into C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject\app\build\intermediates\res\merged\debug\drawable-xxhdpi-v4\quantum_ic_forward_30_grey600_36.png

Error:Execution failed for task ':app:mergeDebugResources'. Error: Failed to crunch file C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject\app\build\intermediates\exploded-aar\com.google.android.gms\play-services-cast-framework\10.0.1\res\drawable-xxhdpi-v4\quantum_ic_forward_30_grey600_36.png into C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject\app\build\intermediates\res\merged\debug\drawable-xxhdpi-v4\quantum_ic_forward_30_grey600_36.png

I am very new to Android developement and really dont know what to do.

I appreciate any comments.

Thanks in advance

EDIT: My mistake! Forgot to copy some files...

回答1:

Failed to crunch file means studio can't process the file. Its too long and it has reached the max file path line of the operating system.

-> Crude way to solve it is move the project to some folder in "C:\".

-> Better way is to change the build directory of the project in the build.gradle file (Project)

allprojects {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    .
    .
}

回答2:

this is because your project path is too long. Please make this as short as possible. It will resolve this error.

Like

C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject

to

C:\ActivityProject

回答3:

The length of the path\file name (the count of all characters in the name)has crossed the maximum limit. This is happening because a combination of length of file name and the multiple nested folder levels.

回答4:

It's because the path length has exceeded the maximum value. You do not have to move your project elsewhere. Just open a shell in the root directory of your hard drive and make a junction to your project:

D:\a\very\long\path\to\your\project

cd \ mklink /j project D:\a\very\long\path\to\your\project cd project You can now make the building process without a pain

回答5:

which means that the path is too long to reach that particular file. make sure that your project is placed under the parent directory(do not go greater than 4 levels ).

example:

C:\Users\marschall\Desktop\googlesamples-android-play-location-2ed2964\ActivityProject

instead use :

C:/your project directory/your project file

the best practice is keep the project as easily available to the compiler.

回答6:

Had the same problem. Move your project into a higher directory (like C:).

Android Studio 2.2 Google play services sync Error

回答7:

In my case with Windows 7 (have to work with that :-|), moving to a higher directory in whatever the drive is located, or reduce the directory name length did the trick.

回答8:

I am using android studio with react-native. I faced the same error regarding 'failed to crunch file'. I just updated my project's gradle from 2.3 to

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
} 

and all started working again.

回答9:

This is happening because file name and path is too long

1) rename the folder to a shorter name

2) move the project to the folder to a simple path like

c:/android projects/Project Sample
