Getting zip expansion file causing NullPointerException. Zip is not placed in right directory of emulator?

Question

I'm trying to run the app in the eclipse emulator. In the ddms perspective, file explorer, I've put my .obb file inside mnt/obb/mypackage.name.example/main.1.mypackage.name.example.obb. Now Im getting NullPointerException at this line:

zip = APKExpansionSupport.getAPKExpansionZipFile(ctx,1, -1);

What could be the problem?

The path needs to be

Android/obb/com.example.android/

Its given here

Just store the file in

/mnt/sdcard/Android/obb/

EDIT

This is a screenshot of an emulator running API Level 17

Image showing /mnt/sdcard/Android folder on emulator running API level 17

EDIT 2

In case you don't have an Android folder inside the sdcard, just create one

This folder hierarchy needs to exist

/mnt/sdcard/Android/obb/

NOTE: This will work only on devices/emulators having an sdcard. In case of a device without external storage, the path is different (since an emulated sdcard is maintained). Check here

there is not Android folder in the mnt/sdcard in the file explorer in the DDMS perspective. should I just create it? – Nazerke Mar 09 '14 at 11:30
Could you tell me the API level of the emulator you are using? – AndyFaizan Mar 09 '14 at 11:47
my emulator is API level 9, 10'1 inch tablet – Nazerke Mar 09 '14 at 11:52
thanks AndyFaizan. Do you know where to put obb for the API level 9. cause my mnt/sdcard is empty. – Nazerke Mar 09 '14 at 11:58
I Checked. You're right about API level 9. No Android folder. I'm checking for a solution. – AndyFaizan Mar 09 '14 at 11:59
Why don't you try and make the /Android/obb hierarchy inside inside the mnt/sdcard/ folder? – AndyFaizan Mar 09 '14 at 12:11
if i try to create a folder "Android" in sdcard it says: "Failed. Read only file system" – Nazerke Mar 09 '14 at 12:45

Try remounting the file system. First -> adb shell – AndyFaizan Mar 09 '14 at 12:50
