I did clean build without any options, which means arm build. ia32 test device runs well with it. libchromeshell.so: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped
I was curious how ia32 test device run well android chrome which I downloaded from google play. I did adb pull and unzip the chrome apk > file libchromeview.so libchromeview.so: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, stripped It is arm binary. It's convenient to test both ia32 test device and nexus 5. but it's strange. DS On Tue, Mar 25, 2014 at 3:19 AM, Zhu, Yongsheng <[email protected]>wrote: > I think Gu Yang's right.
