环境
博主测试环境是在Android 7.0上，理论上不用任何修改就可以适合所有Android版本。
memtester
memtester主要用于测试内存稳定性
官网：http://pyropus.ca/software/memtester/
版本：memtester-4.3.0.tar.gz（目前最新版本-2018.10.21）
官方已经预编译了大部分Linux系统的二进制文件，可以直接使用，现在我们将它移植到Android系统中。
移植
首先我们看看Makefile文件它在Linux系统是怎么编译的，这里移植memtester-4.3.0.tar.gz压缩包里的文件不需要任何修改。
memtester: \
$(OBJECTS) memtester.c tests.h tests.c tests.h conf-cc Makefile load extra-libs
./load memtester tests.o `cat extra-libs`
从上面的Makefile可以知道，要编译memtester需要编译memtester.c和tests.c以及相关的头文件，所以我们可以写出下面的Android.mk文件。
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := memtester.c tests.c
LOCAL_MODULE := memtester
LOCAL_C_INCLUDES := $(LOCAL_PATH)
include $(BUILD_EXECUTABLE)
我们把下载下来的memtester-4.3.0.tar.gz解压到system/core/目录下，并命名为memtester目录，并把Android.mk放到同一目录。文件如下显示。

接下来mm此目录就可以编译生成
lemon@ubuntu:~/Develop/OrangePi_Lite2/android/system/core/memtester$ mm -j8
........

[100% 6/6] Install: out/target/product/petrel-p1/system/bin/memtester
make: Leaving directory '/home/lemon/Develop/OrangePi_Lite2/android'
#### make completed successfully ####
然后就可以通过
adb push memtester /system/bin/
adb shell "chmod 777 /system/bin/memtester"
adb shell memtester
来执行测试。
由于我需要打包到系统，所以还需要在device.mk里面进行定义。

编译出system.img进行烧写测试。
测试
使用方法：Usage: memtester [-p physaddrbase [-d device]] [B|K|M|G] [loops]，比如memtester 5M 1，对应测试1次5M内存
petrel-p1:/ # memtester
memtester version 4.3.0 (32-bit)

pagesize is 4096
pagesizemask is 0xfffff000
need memory argument, in MB
Usage: memtester [-p physaddrbase [-d device]] <mem>[B|K|M|G] [loops]
查看系统空闲内存，还有251M
petrel-p1:/ # free -h
total used free shared buffers
Mem: 978M 727M 251M 0 13M
-/+ buffers/cache: 714M 264M
Swap: 128M 0 128M
演示：memtester 5M 1，这里只是演示，测试1次5M内存，实际项目中这两个参数应尽可能大，才能覆盖整块内存，才能达到压力测试的结果，测试时失败有相应的log，我这里比较难复现就不贴了。
