Cannot Write to sdcard in Android emulator(无法在 Android 模拟器中写入 SD 卡)
问题描述
我在 AndroidManifest.xml 中添加了这一行:
I have added this line in the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
但是，当我运行代码写入 sdcard 时，我收到此错误:
However, when I run code to write to the sdcard , I get this Error:
02-19 13:24:46.760: E/CameraTest(598): /mnt/sdcard/image.jpg: open failed: EACCES (Permission denied)
我该如何解决这个问题?
How do I solve this problem?
我正在使用添加了 SDCard 的 Android 模拟器.
I am using the Android Emulator with SDCard added.
EDIT-2:我知道现在的问题是什么:我调用了函数 Environment.getExternalStorageState() 并且我被删除"了.任何人都知道如何解决这个问题并使状态 MEDIA_MOUNTED
EDIT-2: I know what the problem is now: I have called the function Environment.getExternalStorageState() and I get "removed". Anyone knows how to fix this and make the state MEDIA_MOUNTED
谢谢！
推荐答案
好的，我已经解决了这个问题.这是我在安装 sdcard 时遇到的问题，并且 android 不允许路径中有空格！
Ok So I have solved this. It was a problem I faced with mounting the sdcard and that android doesn't allow spaces in the path!
这是一个很好的程序(如果也使用 eclipse):http://www.brighthub.com/mobile/google-android/articles/33240.aspx
Here is a good procedure to follow (if eclipse is also used) : http://www.brighthub.com/mobile/google-android/articles/33240.aspx
注意:如果路径中有空格，请将 sdcard 图像文件移动到其他位置，然后使用 sdcard 运行模拟器命令，一切正常！
NOTE: in case the path has a space in it, move the sdcard image file to somewhere else and then run the emulator command with the sdcard and everything should work fine!
