What are the advantages and disadvatnages of open source? |
The Android source code and the development and sale of apps are not closely guarded. Apps can be purchased or downloaded from Google Play, but they can also be obtained from other sources such as Amazon.com or directly from a developer. This freedom comes with a cost because users are not always assured of high-quality, bug-free apps, and developers are not always assured of a convenient market for their apps. Because any smart phone or tablet manufacturer can modify the Android source code, many variations of Android exist. These variations can make it difficult for developers to write apps that port to any Android platform. It can also make it difficult for users to learn to use new Android devices because of these inconsistencies. |
