reason:

This is a problem with the 9-patch image resource file

resolvent:

1. Modify the 9-patch image:

Click gradle console in the lower right corner to view the detailed log of gradle, such as my project:

Executing tasks: [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies]

Configuration on demand is an incubating feature.
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to D:\Users\Android\sdk\ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

useNewCruncher has been deprecated. It will be removed in a future version of the gradle plugin. New cruncher is now always enabled.
Incremental java compilation is an incubating feature.

First look at the English meaning:

In the above error log, we know which 9-patch images are problematic, and then find them one by one. The operation is as follows:

Hold down Ctrl or shift, click the left mouse button, and adjust the black part on the boundary pixel until we need the area and do not report an error.

After the completion of sync, clean it.

2. Add 9-patch ignore:

If there are any problems, please click build.gradle Add Android studio and ignore the check of 9-patch

    aaptOptions {
        cruncherEnabled = false
        useNewCruncher = false
    }

As follows:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.3'

    aaptOptions {
        cruncherEnabled = false
        useNewCruncher = false
    }

    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/ASL2.0'
    }

        }
    }
}
