Yes there are plenty of apps that use a lot of C and C++, and we all join in the Anonymous NDK user group meetings.<p>- The bug tracker is full of NDK issues<p>- GDB works, eventually. If one has the right set of versions and mobile firmware<p>- Integration with the first official IDE (Eclipse CDT) kind of worked, after one turned off indexers, did a few plugin customizations, and even then not really<p>- When Android Studio was announced, silence ensued about NDK future. When Jetbrains announced CLion, there was the hope that it might came to Android Studio, still silent all the way up to Google IO 2015.<p>- No pre-defined templates for mixed code applications<p>- Even today Gradle support for NDK builds is flaky and not final. I am yet to be able to have the samples build out of the box.<p>- The set of official C++ libraries is quite limited, most game related APIs are exposed. Even C++ libraries used by the Java layers like Skia are not exposed to the NDK.<p>- By limiting NDK to a few basic POSIX APIs and Android game related APIs, everyone has to pack into their APK everything from JNI wrappers, image loaders, network access, the whole stuff.<p>Now compare this with using C++ in iOS with help of Objective-C++ or on Windows Phone with help of C++&#x2F;CX.<p>First class tooling support, mixed debugging that works and no need to keep on writing wrappers.<p>Even Microsoft&#x27;s tooling for Android NDK is looking better than what Google does for <i>their own</i> platform.<p>As for Djinni, I am yet to make it work on Windows.
