android5.1 应用无法安装等问题

09-01 00:00:03.596 F/patchoat(  391): art/runtime/gc/heap.cc:286] Check failed: non_moving_space_mem_map != nullptr Failed to mmap at expected address, mapped at 0x6c00     0000 instead of 0x73955000 : Requested region 0x73955000-0x77955000 overlaps with existing map 0x75fd8000-0x75fd9000 (/system/framework/arm/boot.oat)

 

内存段冲突

kernel/arch/arm/configs/s5p4418_project??_defconfig 中如下定义

CONFIG_PAGE_OFFSET=0x80000000

memory.h 中

#define PAGE_OFFSET        UL(CONFIG_PAGE_OFFSET)
#define TASK_SIZE        (UL(CONFIG_PAGE_OFFSET) - UL(0x01000000))

 

在　build/core/dex_preopt_libart.mk

LIBART_IMG_TARGET_BASE_ADDRESS := 0x70000000

TASK_SIZE　（task占用的内存）　和　LIBART_IMG_TARGET_BASE_ADDRESS　刚好在同一地址段

//---

改法：LIBART_IMG_TARGET_BASE_ADDRESS := 0x30000000

//---

 

在调试ａｎｄｒｏｉｄ５．１平台时因为这个问题会引发一系列问题，

1.存储空间不足

2.F/dex2oat (  431): art/runtime/runtime.cc:836] Check failed: options->boot_class_path_ != nullptr

3.每次开机进ｌａｕｎｃｈｅｒ前都会重新装载组件

４．ａｐｋ无法ｉｎｓｔａｌｌ

等等
