"Found pixel at #" error

[kckunal2612]

I am using Android Studio 1.5, with the build tools version 23.0.2, and am getting a Gradle Build Error for every 9-patch image that I use (using your tool).
Here is the complete error message from GradleBuild Log -

AAPT: ERROR: 9-patch image /home/kunal/AndroidStudioProjects/MyApplication/app/src/main/res/drawable-hdpi/munchery_ondemand.9.png malformed.

Add below line inside build.gradle
aaptOptions.setProperty("cruncherEnabled", false)

Same problem here with drawables generated by Simple Nine-patch Generator.
Oddly enough the issue only happens for xhdpi, xxhdpi, xxxhdpi (?!)

Setting AAPT cruncherEnabled to false doesn't seem to have an effect for me.

@mukesh4u
FYI It appears AAPT cruncher setting applies to non-9patch only, see below:
https://medium.com/@duhroach/smaller-pngs-and-android-s-aapt-tool-4ce38a24019d#.647noh4n1

aaptOptions {
 cruncherEnabled = false
}

This will turn off the AAPT png optimization for non-9patch PNG files inside of your APK (I haven’t figured out what it does with 9Patches yet…)

Please re-open if this is still a problem (and attach an example file that's causing the errors); I'm not seeing any errors.

@romannurik Having same error.

UPD. Problem solved by opening image in build-in Android Studio 9patch editor, making slight change and save, then revert this change and save again.

This is indeed a bug with Android Asset Studio. Import the attached xxxhdpi source file, set regions and then export and get the attached zip. The xxxhdpi file produces the error:

AAPT err(Facade for 1513812613) : No Delegate set : lost message:ERROR: 9-patch image /home/bob/workspace/cards/cards-android/app/src/main/res/drawable-xxxhdpi/medium_button.9.png malformed.
AAPT err(Facade for 1513812613): Frame pixels must be either solid or transparent (not intermediate alphas).
AAPT err(Facade for 1513812613): Found at pixel #125 along top edge.

Inspect pixel 125 and you will see it indeed has alpha 0x07

medium_button.9 (7).zip
