• Problem in User Interface
Android does not follow a common UI process during their application development. Google till date has not introduced a common User Interface rule that needs to be followed. This in turn has led to certain applications being incompatible with certain devices. So android developers and designers should make sure they must build applications with responsive layout.
• Software Fragmentation Issue
Several versions of Android operating system are available on different devices. Timely upgrades change the version of Android OS that runs on the device. This implies that the developers can’t just focus on the most recent versions of the OS as not everyone upgrades their devices. It is inconvenient for many users to upgrade their operating systems because manufacturers play a vital role in device configuration.
• Usage of Third Party API
Certain third party API is device dependent and this restricts the usage of many apps across different devices. The SDK and cross-platform IDE does not allow android developers to use a single API across the range of versions.
• Security Issue
Recently Android mobile devices are getting affected by malware that is similar to PCs as a result of extensive internet usage. Lack of stringent rules in the area of software fragmentation in Android has led to proliferation of malware threats. To make things worse these security issues are quite difficult to fix and it is often one of the biggest challenges faced by android developers.
• Patent Issue
Android is open source so there is a possibility for imitation of applications that already exist. Many a times user interface and scenario of the application vary but the concept would have an obvious similarity with the existing applications. One of the reasons for this issue is there are no prescribed quality check rules for uploading apps in Android play store.
