[android-developers] Re: mkdir() fails when min sdk version is 4
There is no uses-permission-group tag. Permissions are just for declaring permissions, for help in displaying them to the user. You are right. That was careless of me. I mistakenly used that tag after looking at http://developer.android.com/reference/android/Manifest.permission_group.html Another related question is that the Vibrant has 16 GB as internal storage. But that's where the /sdcard directory is. There is also another replaceable 2GB MicroSD slot. If I want to write to that drive, how do I access it and does Android consider that as external storage as well? The Android SDK currently only supports one external storage, which for devices with both internal media mountable for USB mass storage and an SD card should be the internal media. I guess this means that I can't programatically access the microSD card. The micro SD card shows up as /sdcard/sd. Which I guess is how Samsung did it and shouldn't be depended upon. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: mkdir() fails when min sdk version is 4
Actually, I made a mistake. If I have the uses-sdk in the manifest,
no matter what the value, it fails to create the directory. I do have
the write_external_storage permission.
The code used to work until I upgraded the SDK to 2.1 I think. This
used to work till around 2.0 of the sdk.
If I create the directory under data/data using
File basedirectory = getFileStreamPath(basedir);
subdirectory = new File( basedirectory, subdir_0/subdir_1 );
but I don't want the directory to be deleted when the app is
uninstalled.
The manifest file is as under.
?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=test.test
android:versionCode=1
android:versionName=1.0
uses-sdk android:minSdkVersion=4/
uses-permission-group android:name=android.permission-
group.STORAGE /
application android:icon=@drawable/icon
android:label=@string/app_name
activity android:name=.Test1
android:label=@string/app_name
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /

/manifest

The following code works when I either have no min sdk version

just returns false.
String msg;

System.out.println(msg);
Am I doing something wrong here? Or is this a bug? I'd prefer not to
set the target to 2.1 and min version to 1.6. But right now, I have
to set it to 2.0 for it to work.

[android-developers] Re: mkdir() fails when min sdk version is 4
Thanks Dianne. That was it. It worked as soon as I changed uses-permission-group android:name=android.permission- group.STORAGE / to uses-permission android:name=android.permission.WRITE_EXTERNAL_STORAGE / I had neither in the old code. Probably a tightening of specs in 2.1. I do wonder what the permission group does. I thought that I saw that in some old post and used it. Seems like the correct one since I assumed it would allow me to read/write/rename/delete files on the external storage. Another related question is that the Vibrant has 16 GB as internal storage. But that's where the /sdcard directory is. There is also another replaceable 2GB MicroSD slot. If I want to write to that drive, how do I access it and does Android consider that as external storage as well?
