Null data in IAB activity result (-1002 bad response received) Solution on MIUI

會發生此原因可能是google play的後臺彈窗顯示權限沒開,

用小米手機的話必須將google play的"後臺彈窗顯示"設為允許,

這樣就能使用內購服務了.


This In-APP billing error may happens on  Xiaomi serials phone.

You have to go to google play APP setting and change permission to allow of "enable popup windows in background".

紅米 記憶卡置換 將SD卡設為第一順位

2014/10/06 update:
 紅米手機更新新版後似乎有些變動:
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host --- SD卡會變成手機儲存空間,有些遊戲會有問題(ex.蜘蛛人:飛越無限無法下載額外章節 or House of the Dead Overkill:file not found problem)



 or


dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host --- SD卡仍是SD卡,如果已將手機空間蔽屏,會無法使用相機


=====================================================================

此方法需準備一張SD卡容量越大越好(最大32GB)

1. 手機要先root. (沒有root可用root大師,或是百度一鍵root)

2. 將800MB手機儲存空間內的資料COPY到SD記憶卡內,然後格式化800MB那個空間.

3. 用Root Explorer到目錄:   \etc 找到vold.fstab

4. Root Explorer切換為 "Mount R/W" 這樣才能修改系統檔案.

5. 打開vold.fstab照以下修改:

找到兩行:
修改前:
dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host

dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host

修改後:
#dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host

dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host

將上面註解掉是為了將800MB的手機空間蔽屏,不要使用,下面改成0是將SD卡預設改成"手機空間".
這樣以後裝遊戲或軟體就不會出現"手機內存不足"的問題了.
