AsyncTask – Order of Execution / Versions

Order of execution


When first introduced, AsyncTasks were executed serially on a single background thread. Starting with DONUT, this was changed to a pool of threads allowing multiple tasks to operate in parallel. Starting with HONEYCOMB, tasks are executed on a single thread to avoid common application errors caused by parallel execution.

If you truly want parallel execution, you can invoke executeOnExecutor(java.util.concurrent.Executor, Object[]) withTHREAD_POOL_EXECUTOR.

Android Studio – Jdk Sources & Javadoc

Setup Android Studio 2.3 for pojo java library javadoc and sources support.

  1. link jdk javadoc location to ~/android-studio/jre/docs/api
  2. link jdk src.zip to ~/android-studio/jre/src.zip

These files can be copied and or decompressed, as well.
In the jdk.table.xml file, note that zip files are accessed with the “jar:///…….!\ protocol

~/.AndroidStudio2.d/config/options/jdk.table.xml

formatting sucks.

rh7 android studio install

How to solve “Unable to run mksdcard SDK tool” when installing Android Studio on Fedora 21?

The Fedora Project Wiki also has an article about how to set up Android Development.

For 64-bit systems, you will have to install these packages

yum install glibc.i686 glibc-devel.i686 libstdc++.i686 zlib-devel.i686 ncurses-devel.i686 libX11-devel.i686 libXrender.i686 libXrandr.i686

This exact command also worked on RHEL 7 64-bit. – coreydaley Apr 8 ’16 at 15:49
