How to create sub-folder in SD Card, using Java code

If you want to create sub-folder in SD Card using Java code, you can use the mkdir() method of java.io.File class.



ex.

String newFolder = "/myFolder2";
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File myNewFolder = new File(extStorageDirectory + newFolder);
myNewFolder.mkdir();


And also, AndroidManifest.xml have to be modify to add permission of "android.permission.WRITE_EXTERNAL_STORAGE"
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.exercise.AndroidNewFolder"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".AndroidNewFolder"
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>
<uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>
