Aapt: error: resource android:color/system_neutral1_1000 not found.

score:2

Not quite sure if this is the solution (it worked for me) but updating the compileSdk and targerSdk to 31 alongside with updating these libraries solved the error in my case:

implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
implementation 'com.google.android.material:material:1.5.0'

score:7

I ran into this error as well, when trying to target API 30 in a Java project. I had tried to downgrade the appcompat dependency only and got these errors. Turns out you need to downgrade the material dependency as well.

To target API 30, you need to downgrade both androidx.appcompat:appcompat and com.google.android.material:material to older versions.

Change the versions from:

implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'

To:

implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'com.google.android.material:material:1.4.0'

score:11

I've meet this error, and it's solved. Change or downgrade your dependencies should solve this issue. If you meet this error from this link, I suggest you should change this both, from :

implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.5.0'

to :

implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.4.0'

then, run your app again. I think this method works. This usually happen if you create your new project, but you didn't notice this error, when you trying to run your app.

score:21

The problem is in the following line:

implementation 'com.google.android.material:material:1.5.0-alpha03'

I used this and got the same error. Replacing it with the following line fixed the problem:

implementation 'com.google.android.material:material:1.5.0-alpha02')
