Sometimes the Apps you want to install on your Nexus 7 tablet or Nexus 5 phone from Google Play will not work. It could be mainly due to compatibility. When you want to install an app from unknown or other sources as APK file on your phone or tablet, this tip will be useful. Find below simple method shows how to install 3rd party (or other unknown sources) apps on Nexus 7 and Nexus 5. You can utilize this method to install apps which are not listed in Google play. Also, it is applicable for Nexus 9 tablet.
By default installing third party applications (unknown sources) is disabled on Nexus 7 and Nexus 5, Google recommends to install only the Apps which available in Google play. Because it was tested and approved by Google. But you can take your own risk by installing third party applications on your device if really required and important.
There could be some potential security concerns when you install third party apps from other sources, but it depends on the source of app too. For example, if you download Viber or Adobe flash player apps APK files from official sites to install, I don’t think it could be harmful for the device, because the same apps available for other devices in Google play. But, definitely some compatibility issues could occur while using these apps, because that’s the main reason why the particular app is still not available in Google play for your device.

Once the unknown sources app installation is enabled, you need to manually download the APK file of the app from internet browser or transfer the file to phone or tablet by browsing the storage of the device. Then opening the APK file will initiate the installation of the App.
Somehow I feel it is not recommended to enable unknown sources apps and install it on the tablet or Smartphone which is under warranty and new. Incase these apps make trouble by non-compatibility, poor coding and support for your device or some other issues then you will have tough time with your new Android device. Even it can affect the warranty too.
