Can't write file to sdcard

Romeo Ordos · by **Romeo Ordos** » Wed Dec 02, 2009 6:15 pm

I try to write a file to sdcard using simple code:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

File file = new File("/sdcard/file.txt");
                try 
                {
                        file.createNewFile();
                        Log.e("Info", "File Created!");
                } 
                catch (IOException e) 
                {
                        Log.e("Error", e.toString());
                }
 
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

Operation successful in G1, but I have got java.io.IOException: Parent directory of file is not writable: /sdcard/file.txt in emulator

SDcard was created using wizard while creating virtual device in the latest AVD Manager(Linux). Virtual Device version is 1.6.
I have tried to change permissions of sdcard by "chmod 777 /sdcard" command in adb shell, but no effect.

DDMS shows: sdcard 1970-01-01 00:00 d---rwxr-x

Any idea?

Maybe you forgot to add permissions to andriod manifest file.

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

Thanks. That's right. But I can't understand why real device writes files to SD without permissions!?

If you're running or debugging the program on a handset through Eclipse, don't forget to unmount or turn off USB storage to your SD card.

It doesn't allow both your computer and the Android system to access the SD Card at the same time.

Happy coding...

I could not write to my sdcard in the emulator nor on the device for quite a while, and I had the
<uses-permission android:name=android.permission.WRITE_EXTERNAL_STORAGE/>
line in the Manifest file.

I had assumed that it would need to be somewhere within the
<application ...
and
</application> tags

Finally, I moved it outside of those, next to the uses sdk tag, and now I can write to the sdcard.

Check the name of the file that you're trying to write to. I was getting the same error, and my permissions were correct, but it turns out android didn't like the fact that I had ":" and "+" in the filename. There may be other symbols that it dislikes as well.
