Execution failed for task :':app:mergeDebugResources'. Android Studio

Try clean project...

If it doesn't work... Then... Goto build.gradle in project section

Try downgrading the gradle version

From...

dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
}

To...

dependencies {
    classpath 'com.android.tools.build:gradle:1.2.0'
}

Then gradle.properties, add this

 org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

Sync it... Clean/Rebuild... It worked for me... So, I am sharing...

I can see libc error in the log.

install these packages in your system

sudo apt-get install lib32stdc++6 lib32z1 lib32z1-dev

Restart android studio after installation

I had that problem, but it was because my images changed them manually from .JPG to .PNG, so I just changed them with PNG paint and solved the problem

This issue can be resolved by trying multiple solutions like:

1. Clean the project OR delete build folder and rebuild.
2. Downgrading gradle version
3. Check for the generated build file path, as it may be exceeding the windows max path length of 255 characters. Try using short names to make sure your project path is not too long.
4. You may have a corrupted .9.png in your drawables directory

In My case, I've written below code in build.gradle

android {
// ...
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
// ...
}

It's work for me!...
