android move data to sd card

Read the SD card file information and add it to the listview to display it: Listview obtains the information of the SD FileCode: List Draw different images based on filetype:

. Propertyconfigurator. getconfigurator (this). Configure (); 4. Put the microlog. properties file in the assets folder. Note: The assets folder is the same as the res folder. Then change the microlog. properties file to the following: Microlog. Level = debugMicrolog. appender = logcatappender; fileappenderMicrolog. formatter = patternformatterMicrolog. formatter. patternformatter. pattern = % C [% P] % m % t 5. Write log records Logger. debug ("My debug "); 6. Add

The specific usage is as follows: 1. Download Download the http://code.google.com/p/microlog4android/downloads/list and microlog. properties files to the microlog4android-1.0.0.jar 2. Create a logger object Private Static final logger = loggerfactory. getlogger (main. Class ); 3.ProgramThe initialization method in the oncreate method of the first activity Propertyconfigurator. getconfigurator (this). Configure (); 4. Put the microlog. properties file in the assets folder. Note: Th

Memory (RAM)The total memory size information of Android is stored in the system's/proc/meminfo file, which can be obtained by reading this file: Public voidgettotalmemory () {String str1= "/proc/meminfo"; String str2=""; Try{FileReader fr=NewFileReader (STR1); BufferedReader Localbufferedreader=NewBufferedReader (FR, 8192); while((str2 = Localbufferedreader.readline ())! =NULL) {log.i (TAG,"---" +str2); } } Catch(IOException e) {}}The opera
