============ Problem Description ============
Write your own apk, installed on the Android phone, the program will be run to create a SQLite database;
With eclipse, you can see the location of the database, I put the phone into the computer, after the USB connection, but not in the phone to find the database file (APK is absolutely installed on the SD card), someone said to have root permissions. Do not know how to achieve, if you want to write a program to achieve, please master pointing ideas, list the relevant key functions, thank you
============ Solution 1============
Their own application to copy their own database, without root, direct file copy on the line, probably as follows:
File F = new file ("/data/data/application's package name/databases/database name"); Like "/data/data/com.hello/databases/test.db."
String Sdcardpath = Environment.getexternalstoragedirectory (). GetAbsolutePath ();
File o = new file (sdcardpath+ "cp.db"); Destination address on the SDcard
if (f.exists ()) {
FileChannel Outf;
try {
Outf = new FileOutputStream (o). Getchannel ();
New FileInputStream (f). Getchannel (). TransferTo (0, F.length (), OUTF);
} catch (FileNotFoundException e) {
E.printstacktrace ();
} catch (IOException e) {
E.printstacktrace ();
}
Toast.maketext (Mainpage.this, "done", Toast.length_short). Show ();
}
