Work Manager 

WorkManager is an API that makes it easy to schedule deferrable, asynchronous tasks that are expected to run even if the app exits or the device restarts. The WorkManager API is a suitable and recommended replacement for all previous Android background scheduling APIs
Device support from 14 -22 it will work on alarm manager with broadcast to process scheduling and GCM NetworkManager 
Device above 23 + all uses JobSchedular 

usecases : 
Dynamic  Feature modules and clean architecture
Backup chat like whatsapp after a hours or 1 in a day 
update news in any news app - phone in charge or connect with constraint and executes the task and impl

MIPS uses a single syscall instruction for all access to operating system services. The setup for a syscall instruction puts a syscall code into a register. ... They allocate and keep track of the addresses and allow a programmer to use labels instead of addresses in assembly language code.

MIPS (Microprocessor without Interlocked Pipelined Stages) is a reduced instruction set computer (RISC) instruction set architecture (ISA)
A reduced instruction set computer, or RISC (/rɪsk/),

 For example, if we are having mips, x86, armeabi, armeabi-v7a, armeabi-v8a, then the .so file will be generated for all the five architectures. So, if the size of one .so file is 5MB then the application size should be 5MB but in reality, it will be of 5*5 = 25MB.

Arm, previously Advanced RISC Machine, originally Acorn RISC Machine, is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments.

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have an LF.

If you are a single developer working on a windows machine, and you don't care that git automatically replaces LFs to CRLFs, you can turn this warning off by typing the following in the git command line

git config core.autocrlf true



rm -f ./.git/index.lock

PROGUARD
Generally ProGuard is a tool to help minify, obfuscate, and optimize your code.
It is not only especially useful for reducing the overall size of your Android application as well as removing unused classes and methods that contribute towards the intrinsic 64k method limit of Android applications. Because of the latter issue, ProGuard is often recommended to be used both in development and production especially for larger applications.
ProGuard can be enabled by using the minifyEnabled option for any build type. 
If you intend to use it for production, it is highly recommended you also enable it on your development.

Generally retracing this kind of error log have two ways.Lets discuss one by one
Get the mapping.txt file and retrace the logs using proguardgui

This crash is present on:

all Samsung devices 7.0

all Nexus devices on 7.1.2


When the device is being restarted, you cannot run an app. Any app, not just yours but any given app cannot run when the device is restarting. AFAIK it occurs when you try to do something when the system crashes. 
Meaning if the system crashes and as it restarts your app starts a service or does something you get that error.
