my phone is nexus 6 build aosp of shamu-userdebug which version is : N6F26U android-7.1.1_r28
I want to get my app native heap info the backtrace of malloc or other allocation. I followed https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md. for example: i did this command: adb shell stop adb shell setprop libc.debug.malloc.options backtrace adb shell setprop wrap.<my app name> '"LIBC_DEBUG_MALLOC_OPTIONS=backtrace logwrapper"' adb shell start but I get nothing from logcat. As I expect, I would get the following information from logcat: infomation of backtrace like this: 04-14 09:40:38.242 5029 5029 F DEBUG : Build fingerprint: 'Android/aosp_shamu/shamu:7.1.1/N6F26U/:userdebug/test-keys' 04-14 09:40:38.242 5029 5029 F DEBUG : Revision: '0' 04-14 09:40:38.246 5029 5029 F DEBUG : ABI: 'arm' 04-14 09:40:38.246 5029 5029 F DEBUG : pid: 5009, tid: 5009, name: putmethod.latin >>> com.android.my app name <<< 04-14 09:40:38.246 5029 5029 F DEBUG : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 04-14 09:40:38.246 5029 5029 F DEBUG : r0 00024104 r1 0002411c r2 00000000 r3 00000000 04-14 09:40:38.246 5029 5029 F DEBUG : r4 00000000 r5 be9f1094 r6 000024b0 r7 0000004c 04-14 09:40:38.247 5029 5029 F DEBUG : r8 00000054 r9 00000004 sl 00000023 fp be9f1038 04-14 09:40:38.247 5029 5029 F DEBUG : ip be9f0fe8 sp be9f1020 lr b3296af9 pc a9fb5580 cpsr 600e0010 04-14 09:40:38.250 5029 5029 F DEBUG : 04-14 09:40:38.250 5029 5029 F DEBUG : backtrace: 04-14 09:40:38.250 5029 5029 F DEBUG : #00 pc 000c2580 /system/lib/libjni_latinime.so (__cxa_get_globals+276) 04-14 09:40:38.250 5029 5029 F DEBUG : #01 pc 000c280c /system/lib/libjni_latinime.so (__cxa_begin_catch+12) 04-14 09:40:38.250 5029 5029 F DEBUG : #02 pc 0007a1d0 /system/lib/libjni_latinime.so so, How to get malloc's backtrace ? thx kun -- -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting --- You received this message because you are subscribed to the Google Groups "android-porting" group.
