The alphabet does now not adjust the Android smartphones, drugs, and phablets manufactured with the aid of diverse corporations. Hence, the devices synthetic by means of different agencies include varying hardware functions notwithstanding being powered by way of the same version of Android. That is why; it turns into vital for developers build cell apps via focused on a huge variety of gadgets powered with the aid of one-of-a-kind versions of Android.

While making plans, developing, and trying out the cell app, they want to cognizance substantially on its accessibility, capability, performance, usability, and security of the mobile app to preserve the customers engaged no matter their choice of Android tool. Also, they want to discover ways to make the app deliver personalized consumer revel in across various gadgets and working gadget version. They similarly want to cope with some of the commonplace demanding situations to increase a strong Android app.

Understanding 7 Common Challenges Faced by way of Android App Developers

1) Software Fragmentation

As stated earlier, the market proportion of man or woman variations of Android differs. According to the state-of-the-art data released via Google, the most current model of its mobile working gadget – Nougat – has a market proportion lower than its predecessors – Marshmallow, Lollipop and KitKat. Each new edition of Android comes with several new features and improvements. The builders must encompass particular capabilities in the app to make it supply the finest consumer enjoy through taking gain of these new capabilities. At the identical time, they also need to make certain that the app provides wealthy and personalized user revel in on gadgets powered by using older variations of Android. The developers ought to goal a couple of variations of Android to make the application famous and worthwhile inside the short run.

2) Varying Hardware Features

Unlike different cellular running systems, Android is open supply. Alphabet allows tool producers to customize its operating device according to their precise wishes. Also, it does no longer adjust the Android gadgets released by way of numerous producers. Hence, the devices include varying hardware features notwithstanding being powered with the aid of the same version of Android. For example, devices powered by using Android Nougat may additionally fluctuate from every different inside the class of display size, decision, camera and different hardware features. While growing an Android app, the developers want to ensure that it promises personalized enjoy to every person by using getting access to all hardware features of his device.

3) No Uniform User Interface Designing Process or Rules

Google has now not released any common user interface (UI) designing system or regulations for the cell app builders. Hence, most builders construct Android apps without following any fashionable UI improvement process or guidelines. When the builders create custom UI interfaces of their very own way, the apps do not look or characteristic consistently throughout distinct devices. The incompatibility and diversity of the UI impact the person experience added by using the Android app directly. The clever builders opt for the responsive layout to maintain the UI consistent across many gadgets. Also, the builders have to check the UI of their mobile app comprehensively through combining each actual devices and emulators. But frequently developers locate it daunting to layout a UI that makes the app appearance regular throughout numerous Android gadgets.

App

4) API Incompatibility

Most builders use 1/3-party APIs to decorate the cellular app’s capability and interoperability. But the best of 1/3-party APIs available for Android app developers differ. Some APIs are designed for a particular version of Android. Hence, these APIs do no longer work on devices powered by exceptional variations of the cell running gadget. The developers need to discover ways to make an unmarried API work on exceptional versions of Android. But they frequently discover it tough to make the app paintings smoothly on extraordinary Android gadgets with the same set of APIs.

5) Security Flaws

Its open source nature makes it easier for tool producers to personalize Android according to their particular desires. But the openness and its large market percentage made Android prone to frequent protection attacks. There are many times when the safety of tens of millions of Android gadgets has been impacted with the aid of protection flaws or bugs like Stagefright, ‘Certified-gate’ most, FakeID, Installer Hijacking and TowelRoot. The developers need to encompass strong safety functions within the utility and use a present day encryption mechanism to hold the user data at ease despite targeted safety attacks and safety flaws in Android.

6) Android Search Engine Visibility

The cutting-edge statistics published on the diverse website depict that Google Play Store has a far better wide variety of cellular apps than Apple App Store. Also, a huge percent of Android tool customers decide upon unfastened apps to paid apps. Hence, the builders need to promote their mobile apps aggressively to perform better down load numbers and put into effect app monetization options. They additionally need to enforce a complete virtual advertising and marketing approach to promote the app via targeting the maximum applicable users. Many developers need to avail the services of digital advertising specialists to promote their apps aggressively.

7) Patent Issues

The customers have the option to select from several Android apps presenting identical capabilities and functionalities. But developers frequently discover it formidable to construct apps with unique functions and functionality. They frequently encompass capabilities and functionalities in the app that make it similar to some of the apps to be had within the same category inside the Play shop. Unlike Apple, Google does no longer put into effect stringent tips to evaluate the excellent of recent apps being submitted to its app save. Lack of standardized great evaluation guidelines frequently makes builders deal with problems related to the patent. Some developers ought to design and alter their apps in future to keep away from patent problems.

Android Phones

The function that a Digital Forensics Investigator (DFI) is rife with non-stop gaining knowledge of possibilities, specifically as technology expands and proliferates into each corner of communications, leisure, and enterprise. As a DFI, we address a day by day onslaught of recent gadgets. Many of these devices, like the mobile telephone or tablet, use common working structures that we need to be familiar with. Certainly, the Android OS is primary inside the pill and cell phone enterprise. Given the predominance of the Android OS within the mobile tool market, DFIs will run into Android devices in the route of many investigations. While there are several fashions that suggest processes to acquiring information from Android devices, this article introduces 4 viable strategies that the DFI need to remember whilst evidence gathering from Android devices.

A Bit of History of the Android OS

Android’s first business release become in September 2008 with version 1.Zero. Android is the open source and ‘free to apply’ operating device for cell gadgets evolved by using Google. Importantly, early on, Google and other hardware agencies formed the “Open Handset Alliance” (OHA) in 2007 to foster and guide the boom of the Android within the market. The OHA now consists of eighty-four hardware companies consisting of giants like Samsung, HTC, and Motorola (to call some). This alliance became installed to compete with companies who had their own marketplace services, consisting of aggressive gadgets offered by means of Apple, Microsoft (Windows Phone 10 – which is now reportedly lifeless to the market), and Blackberry (which has ceased making hardware). Regardless if an OS is defunct or no longer, the DFI must know about the various variations of a couple of working device platforms, particularly if their forensics awareness is in a particular realm, consisting of cell devices.

Linux and Android

Developers

The contemporary generation of the Android OS is based totally on Linux. Keep in thoughts that “primarily based on Linux” does now not mean the same old Linux apps will always run on an Android and, conversely, the Android apps that you may enjoy (or are familiar with) will not necessarily run on your Linux laptop. But Linux isn’t always Android. To clarify the point, please note that Google selected the Linux kernel, the vital a part of the Linux working device, to manage the hardware chipset processing in order that Google’s builders wouldn’t be concerned with the specifics of the way processing happens on a given set of hardware. This permits their builders to cognizance at the broader operating machine layer and the consumer interface functions of the Android OS.

Samsung Android

The Android OS has a massive market share of the cell device marketplace, in most cases because of its open-source nature. An excess of 328 million Android gadgets was shipped as of the 0.33 quarter in 2016. And, according to netwmarketshare.Com, the Android working machine had the bulk of installations in 2017 — almost 67% — as of this writing.

As a DFI, we will anticipate coming across Android-based hardware in the course of a regular research. Due to the open source nature of the Android OS in conjunction with the varied hardware platforms from Samsung, Motorola, HTC, etc., the style of combinations between hardware kind and OS implementation provides an extra mission. Consider that Android is currently at version 7.1.1, yet every telephone producer and mobile tool provider will usually regulate the OS for the specific hardware and provider services, giving an extra layer of complexity for the DFI, for the reason that method to data acquisition can also vary.

Before we dig deeper into additional attributes of the Android OS that complicate the approach to information acquisition, allow’s have a look at the idea of a ROM version so as to be applied to an Android device. As an outline, a ROM (Read Only Memory) application is low-level programming this is near the kernel degree, and the unique ROM application is often referred to as firmware. If you suspect in terms of a bill in contrast to a mobile telephone, the bill could have distinctive ROM programming as contrasted to a cell telephone, on account that hardware capabilities between the pill and cellular phone can be exceptional, even if each hardware devices are from the equal hardware producer. Complicating the need for more specifics in the ROM application, and the particular requirements of mobile carrier carriers (Verizon, AT&T, and so on.).

While there are commonalities of obtaining information from a cell smartphone, not all Android gadgets are identical, specifically in mind that there are fourteen foremost Android OS releases in the marketplace (from variations 1.Zero to 7.1.1), more than one companies with model-specific ROMs, and additional countless custom user-complied editions (purchaser ROMs). The ‘patron compiled editions’ also are version-precise ROMs. In preferred, the ROM-stage updates carried out to every wireless device will comprise running and system basic applications that work for a particular hardware device, for a given supplier (for example your Samsung S7 from Verizon), and for a particular implementation.

Even although there may be no ‘silver bullet’ solution to investigating any Android device, the forensics investigation of an Android device have to follow the identical preferred manner for the collection of evidence, requiring a dependent process and method that cope with the investigation, seizure, isolation, acquisition, exam and evaluation, and reporting for any digital evidence. When a request to take a look at a tool is received, the DFI begins with making plans and training to encompass the requisite approach of acquiring devices, the essential paperwork to aid and document the chain of custody, the improvement of a purpose announcement for the exam, the detailing of the device version (and different unique attributes of the acquired hardware), and a list or description of the data the requestor is in search of to acquire.

Unique Challenges of Acquisition

Mobile gadgets, together with cellular phones, capsules, and so forth., face precise challenges in the course of the proof seizure. Since battery life is confined on cell gadgets and it isn’t always generally advocated that a charger is inserted right into a tool, the isolation level of proof gathering can be an essential nation in obtaining the tool. Confounding right acquisition, the cell records, WiFi connectivity, and Bluetooth connectivity should also be included within the investigator’s recognition at some point of acquisition. Android has many safety capabilities constructed into the smartphone. The lock-display function can be set as PIN, password, drawing a pattern, facial recognition, vicinity recognition, trusted-device popularity, and biometrics which include finger prints. An anticipated 70% of customers do use a few kind of safety on their telephone. Critically, there’s available software that the consumer may also have downloaded, that could give them the ability to wipe the cell phone remotely, complicating acquisition.

It is not going throughout the seizure of the cellular device that the display screen can be unlocked. If the device isn’t always locked, the DFI’s examination might be less complicated because the DFI can trade the settings inside the smartphone promptly. If get right of entry to is authorized to the cell smartphone, disable the lock-screen and exchange the display timeout to its most cost (which can be as much as a half-hour for some gadgets). Keep in thoughts that of key significance is to isolate the smartphone from any Internet connections to save you remote wiping of the device. Place the cell phone in Airplane mode. Attach an outside electricity deliver to the phone after it has been positioned in a static-unfastened bag designed to block radio frequency alerts. Once comfortable, you have to later be capable of enabling USB debugging, in order to permit the Android Debug Bridge (ADB) which can offer appropriate facts capture. While it can be crucial to look at the artifacts of RAM on a cellular device, that is not likely to happen.
