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" />
</intent-filter>
</activity>
</application>
</manifest>
