在Verizon宏达电Droid Incredible Programmitically访问内部存储（不是SD卡）（安卓） [英] Programmitically accessing internal storage (not SD card) on Verizon HTC Droid Incredible (Android)
问题描述
我试图找到如何以编程方式访问信息宏达电Droid Incredible的应该 8GB 内部存储内存。
I'm trying to find information on how to programmatically access the HTC Droid Incredible's supposed 8GB of Internal Storage Memory.
要确定外部存储（SD卡）位置，我使用的命令：
To determine the External Storage (SD Card) Location, I'm using the command:
android.os.Environment.getExternalStorageDirectory().
我一直没能找到任何推论为手机内部存储。
在检查 HTC /谷歌Nexus One 摩托罗拉Droid 和 HTC梦/ G1手机，有（正如所预料的）不没有出现任何挂载点这样的任意内部存储。
In examining HTC/Google Nexus One, Motorola Droid, and HTC Dream/G1 phones, there (as would be expected) does not appear to be any Mount Point for such Arbitrary Internal Storage.
在这些手机中的内部存储被划分到 /数据， /系统和 /缓存分区。
On these phones the Internal Storage is divided amongst /data, /system, and /cache partitions.
难以置信的内部存储肯定是不会被位于 /系统。 /缓存也不太可能，因为这是全球范围内的非可读/非执行。
The Incredible's Internal Storage is certainly not going to be located in /system. /cache is also unlikely given that it is globally non-readable/non-executable.
我读到的评论，手机仍将被限制在 512MB 左右的应用程序，这表明它不是
I'd read in reviews that the phone will still be limited to 512MB or so for apps, suggesting that it is not simply a subdirectory of /data.
任何建议将是极大的AP preciated。我没有机会当然是一个 Droid难以置信单位自己。
Any suggestions would be greatly appreciated. I do not have access to a Droid Incredible unit myself, of course.
推荐答案
在这里有更多的信息：<一href="http://www.droidforums.net/forum/droid-incredible-general-discussions/41766-favor-ask-droid-incredible-user-sd-card-storage-mount-points.html">Droid令人难以置信的存储挂载点。看来，Droid的难以置信装入其内部存储/ EMMC，据说安装R / W的它尚未得到确认的WRITE_EXTERNAL_STORAGE许可是否是必要的，以便获得R / W访问 - 我试图获得这些信息在http：// code.google.com / P / aedict /问题/细节？ ID = 86
There is more information here: Droid Incredible storage mount points. It seems that Droid Incredible mounts its internal storage to /emmc, supposedly mounted r/w. It is not yet verified whether the WRITE_EXTERNAL_STORAGE permission is necessary in order to gain r/w access - I'm trying to get this information at http:// code.google.com/p/aedict/issues/detail?id=86
我很可能通过允许用户两种选择来存储数据解决这样的：
I will probably solve this by allowing the user two options to store the data:
- 在SD卡
- 在Droid难以置信，只有内部存储
编辑：看来，WRITE_EXTERNAL_STORAGE权限是足够了：根据<一个href="http://www.droidforums.net/forum/droid-incredible-hacks/50916-how-i-rooted-my-incredible-installed-busybox.html">http://www.droidforums.net/forum/droid-incredible-hacks/50916-how-i-rooted-my-incredible-installed-busybox.html两者/ SD卡和/ EMMC拥有1015相同的GID。
It seems that the WRITE_EXTERNAL_STORAGE permission is sufficient: according to http://www.droidforums.net/forum/droid-incredible-hacks/50916-how-i-rooted-my-incredible-installed-busybox.html both /sdcard and /emmc has the same GID of 1015.
EDIT2：根据<一个href="http://groups.google.com/group/android-developers/browse_thread/thread/45d96f07abd83549/42d5ec430b2f7572?lnk=raot">http://groups.google.com/group/android-developers/browse_thread/thread/45d96f07abd83549/42d5ec430b2f7572?lnk=raot令人难以置信的回报/ SD卡作为Environment.getExternalStorageDirectory的结果值（）。因此，用户需要决定是否要使用/ SD卡或/ EMMC。令人难以置信的自动检测，可以根据存在/ EMMC路径。
According to http://groups.google.com/group/android-developers/browse_thread/thread/45d96f07abd83549/42d5ec430b2f7572?lnk=raot the Incredible returns /sdcard as the result value of Environment.getExternalStorageDirectory(). Therefore, the user needs to decide whether he wants to use /sdcard or /emmc. The autodetection of Incredible may be based on existence of the /emmc path.
