Nit: this is significantly newer than necessary for SDK 19, if I'm reading
https://developer.android.com/tools/revisions/build-tools.html right.

This is correct and lines up with the build tools we use for building all the
other apps.

+    defaultConfig {
+        applicationId "org.skia.canvasproof"
+        minSdkVersion 9
+        targetSdkVersion 19
+        versionCode 1
+        versionName "1.0"
+    }
+    sourceSets.main.jni.srcDirs = [] //disable automatic ndk-build call
+    sourceSets.main.jniLibs.srcDir "src/main/libs"

Doesn't this need = ?

Done.

+    productFlavors { arm {}; arm64 {}; x86 {}; x86_64 {}; mips {}; mips64 {}; }
+    applicationVariants.all{ variant ->

I wonder if gradle has some include structure so that we don't need to copy this
code every time. The only thing that changes between the copies is the name of
the gyp target.

+        def buildNativeLib = task("${variant.name}_NativeLib", type:Exec) {
+            workingDir '../../../..' // top-level skia directory
+            commandLine constructBuildCommand(variant, "CopyCanvasProofDeps").split()
+            environment PATH: getPathWithDepotTools()
+            environment ANDROID_SDK_ROOT: getSDKPath()
+        }
+        buildNativeLib.onlyIf { !project.hasProperty("suppressNativeBuild") }
+        TaskCollection<Task> assembleTask
+        assembleTask = project.tasks.matching {
+            it.name.contains("assemble") &&
+                    it.name.toLowerCase().endsWith(variant.name.toLowerCase())
+        }
+        assembleTask.getAt(0).dependsOn buildNativeLib
+    }
+}
