does this add more requirements for things people must download from the SDK to
run the app?

I successfully ran android_make Viewer_APK --vulkan using the SDK we gave to
borenet@, so I guess that nothing more needs to be downloaded?

why do we need to update these versions?

[liyuqian, 2016/05/24 20:18:05]

Done. Now only compileSdkVersion is 23, others are back to 19.

     buildToolsVersion "22.0.1"
     defaultConfig {
         applicationId "org.skia.viewer"
-        minSdkVersion 19
-        targetSdkVersion 19
+        minSdkVersion 21
+        targetSdkVersion 23
         versionCode 1
         versionName "1.0"
         signingConfig signingConfigs.debug
