Messages from Log.wtf() sound pretty bad: Android Native Memory allocations and leaks

Prerequisites

Built Android platform code base, SDK and NDK.

Emulator setup

/out/host/darwin-x86/bin/emulator -system /out/target/product/generic/system.img -ramdisk out/target/product/generic/ramdisk.img

adb shell setprop libc.debug.malloc 1

adb shell stop

adb shell start

1 - perform leak detection

5 - fill allocated memory to detect overruns

10 - fill memory and add sentinels to detect overruns

20 - use special instrumented malloc/free routines for the emulator

Host setup

vi ~/.android/ddms.cfg

add a line "native=true"

export ANDROID_SYMBOLS=/out/target/product/generic/symbols

export PATH=$PATH:/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64/bin/

DDMS

/tools/ddms

Select the process in ddms and click on Native Heap tab and select "Snapshot Current Native Heap Usage".

JD said...: How did you get this path -
export PATH=$PATH:/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64/bin/
