What happened when I long press power button ? What is shutdown sequence ? How is it different from desktop linux shutdown sequence? How to change shutdown menu ? Many questions pop-up in mind when we think about Android shutdown sequence. Before you read about shutdown sequence I suggest you to read about  boot sequence article . Android is linux based open source operating system, x86 (x86 is a series of computer microprocessor instruction set architectures based on the Intel 8086 CPU.) is most likely system where linux kernel is deployed however all Android devices are running on ARM process (ARM (formerly Advanced RISC Machine, which was formerly Acorn RISC Machine)) except Intel’s Xolo device ( http://xolo.in/xolo-x900-features ). Xolo comes with Atom 1.6 GHz x86 processor. Android shutdown sequence is different from desktop linux like ubuntu, fedora, etc. In this article I am going to explain shutdown sequence for Android only. Please refer  “Linux Boot and ...

Android Run Multiple AsyncTask Same Time Problem: I am trying to excute Multiple asynctask same time(Android Version 4.0.1) but onPreExcute method only called  after that nothing happen. Solution . AsyncTask uses a thread pool pattern for running the stuff from doInBackground(). The issue is initially (in early Android OS versions) the pool size was just 1, meaning no parallel computations for a bunch of AsyncTasks. But later they fixed that and now the size is 5, so at most 5 AsyncTasks can run simultaneously.  -->  if  (Build.VERSION. SDK_INT  >= Build.VERSION_CODES. HONEYCOMB ) { TestAsyncTask firstAsync =  new  TestAsyncTask(); firstAsync.executeOnExecutor(AsyncTask. THREAD_POOL_EXECUTOR ); } else { TestAsyncTask firstAsync =  new  TestAsyncTask(); firstAsync.execute(); }
