There is an article in the Android Development guide on how to load pictures more efficiently, with the address https://developer.android.com/training/displaying-bitmaps/ Index.html, this article describes in detail how to load high-definition graphics to memory, while avoiding system report oom problem, the article is very good, the sample program can also run directly.

addition, it is necessary to define the QTDIR environment variable before compiling the QT program, but I used bash to add the environment variable definition in. profile, but after I landed KDE, I lost the environment variable of Qtdir, it's strange that I should define it again. Qtdir=/usr/lib/qt3 on SuSE, if installed according to QT documentation, may be qtdir=/usr/local/.qt-------------------------------------------------------------------------

I. Scenario Description:
Recently, a piece of business needs to constantly monitor changes in a directory. If there are files in the directory, start the PHP script to process them. The initial solution was to use crontab to execute the sh script, which is roughly as follows:
SOK=`ps -ef |grep /www/sender.sh | grep -v grep|wc -l`if [[ $SOK
