Question

Running it from the command line resulted in a segmentation fault:

$ emulator -avd nexus_s
Segmentation fault (core dumped)

However, running emulator-arm directly as follows, works fine.

$ emulator-arm -avd nexus_s

I suspect it’s trying to run the mips or x86 version of the emulator.
Is there a way to configure the emulator which executable to start?

All this started after updating to android sdk 17.

Adding the -verbose flag gives the following output (which I don’t think adds any info):

$ emulator -verbose -avd nexus_s

Answer 1

I finally found a solution after following CommonsWare’s tip.
Renaming libOpenglRender.so made the problem go away.

mv tools/lib/libOpenglRender.so tools/lib/libOpenglRender.so.xxx
