- 技术规范似乎表明NC具有8 GB的内存。在寻找应用程序和数据后，大概在我这里会有多少可用？如果可能/必要，我愿意重新开始。
- 普遍认为，假设来自市场的应用程序将在植根植物之后在NC上工作，并且已经安装了市场等，或者有一些与之相关的塔...... （假设我谈论我谈论2.3或更早版本的ROM，而不是撕开-S-SDK 3.0一个）
This is basically a follow-up to my previous question regarding the Nook Color. While my first question was regarding some of the specifics of the root process, I also have two questions about installing apps on a NC after obtaining root:
Below is the output of "df -h -a" command on my Nook Color running CyanogenMod 7.0 ROM (2.3.3) which gives you a break-down of the mounted partitions:
Filesystem Size Used Available Use% Mounted on tmpfs 244.2M 44.0K 244.2M 0% /dev devpts 0 0 0 0% /dev/pts proc 0 0 0 0% /proc sysfs 0 0 0 0% /sys tmpfs 244.2M 0 244.2M 0% /mnt/asec tmpfs 244.2M 0 244.2M 0% /mnt/obb /dev/block/mmcblk0p2 69.5M 107.0K 69.4M 0% /rom /dev/block/mmcblk0p5 440.5M 142.8M 275.0M 34% /system /dev/block/mmcblk0p6 941.9M 347.7M 594.2M 37% /data /dev/block/mmcblk0p7 341.8M 39.3M 284.9M 12% /cache /sys/kernel/debug 0 0 0 0% /sys/kernel/debug /dev/block/vold/179:17 7.5G 5.7G 1.8G 76% /mnt/sdcard /dev/block/vold/179:17 7.5G 5.7G 1.8G 76% /mnt/secure/asec tmpfs 0 0 0 0% /mnt/sdcard/.android_secure /dev/block/vold/179:8 5.0G 57.0M 4.9G 1% /mnt/emmc
Out of 8 Gigabytes of internal memory ~500 MB is reserved for the ROM itself (/rom and /system), ~1.5 GB is for app storage (/data and /cache), 5 GB is for data storage (/mnt/emmc) and another ~500MB reserved for other miscellaneous Android operations. You can also see my 8GB SD Card mounted on /mnt/sdcard.
Keep in mind that these partitions can be (and usually are) remapped based on the needs of a given ROM.
In terms of your question regarding apps from the Market, there are some limitations that mostly depend on the type and version of the ROM you are planning to run. The biggest concern the screen resolution and LCD density. Several apps, including the Market itself (Vending.apk) are quite picky about how well (or even if) they will work properly. Most common side-effect is apps displaying in a tiny window instead of properly scaling. Most can be fixed by disabling Compatibility Mode in Spare Parts, but some (e.g. Google Reader) will only function with a certain LCD density that could be in conflict with other apps.
Keep in mind that most of the custom ROMs for Nook Color are works in progress, so expect to see better compatibility with all apps going forward. Also, if rumors of Froyo (2.2) update for the official Nook Color firmware are true, we could see better performance once the official display/video/audio/etc. driver upgrades are rolled into custom ROMs.
