I am using the ndk along with Eclipse ADT to build apps for Android and it works fine. However I am wondering why the building process involves compiling both for arm and for thumb, ie every time I do a modification in a source file it re-compiles both for arm and thumb. Is it necessary ? If not how can I tell the builder to only compile and link with armabi-V7a ? That would divide by 2 my build process time...

您可能的意思是，对于 arm v6 和 arm v7a？两者都可以编译为 ARM 或 THUMB。这由Android.mk中的 LOCAL_ARM_MODE 控制。要禁用armeabi，请设置

APP_ABI=armeabi-v7a

在Application.mk中。这不仅会减少您的构建时间，还会减少 APK 的大小。
