The sqlite small database is used to save data during development. I will not introduce it here. This article just writes about how to copy the application data into the local SD card. For example: a database named, copying it to the local area is called
The code is as follows:
/**
* Copy the database to the SD card
*
* @deprecated <uses-permission android:name=".WRITE_EXTERNAL_STORAGE"/>
*/
public static void copyDataBaseToSD(){
if (!Environment.MEDIA_MOUNTED.equals(())) {
return ;
}
File dbFile = new File(().getDatabasePath("dandy")+".db");
File file = new File((), "");
FileChannel inChannel = null,outChannel = null;
try {
();
inChannel = new FileInputStream(dbFile).getChannel();
outChannel = new FileOutputStream(file).getChannel();
(0, (), outChannel);
} catch (Exception e) {
(TAG, "copy dataBase to SD error.");
();
}finally{
try {
if (inChannel != null) {
();
inChannel = null;
}
if(outChannel != null){
();
outChannel = null;
}
} catch (IOException e) {
(TAG, "file close error.");
();
}
}
}
The above method of copying the sqlite database to the local SD card on Android is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
