Cannot Write to sdcard in Android emulator

android permissions android-emulator android-sdcard

I have added this line in the AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

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)

How do I solve this problem?

EDIT: I am using the Android Emulator with SDCard added.

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

Thank You!

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!

Here is a good procedure to follow (if eclipse is also used) : http://www.brighthub.com/mobile/google-android/articles/33240.aspx

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!
