We need your manufacturer and model number to be of maximum assistance, but the most likely possibilities are:
1) The file is not in a format recognized by the player - if you have an mp3 player that only plays mp3 or WMA files, then it will not play iTunes files, for instance
2) The file you are transferring has DRM encryption, and your player does not support DRM-encryption (or the reverse - the file does not have encryption, and needs to be encrypted)

Give us your model/manufacturer, and we will tell you exactly what that msg means.

Why can't I parse my package?

Are you getting "there is a problem parsing the package" message when trying to install an android application? Well, that's because it is not verified from Google Play and you're not downloading it from google play store but installing .apk from other source or directly copied on your handset.
In this case, you have to enable the following settings to install it without any problem.
Step 1- Go to device Settings(icon) menu
Step 2- Tap on Security
Step 3- Device administration
Step 4- Unknown sources - Check mark Unknown Sources
That's all. A small post but might be helpful for beginner Android developers.

How to download google play servies

wikiHow to Download the Google Play App Store

You have to download the Google Play Store APK (i. e. installation file) to a device, transfer it to your tablet, find it there, and install it there. The link above gives you at least one source (there are others) from which you can download the APK file safely. Note that accepting programs from "unknown" sources is a setting that has to be applied to your device. It will permit installaton from sources other than Google Play.

Unknown sources option is listed under the option 'security' in settings.
Most of the android phones have Google Play preinstalled in them.

Can't dowload app says default not compatable

First, are you downloading from Google Play or another website?

if you are downloading from GooglePlay, there a few apps, however infrequent, that are incompatible with the Nextbook. You can try to change the settings to allow for apps from other sources (Menu>Settings>Applications>Unknown Sources).

hope it can help you more or less!
