Here is some code to make it work
private void importDB() {
try {
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite()) {
String currentDBPath = "//data//" + "<package name>"
+ "//databases//" + "<database name>";
String backupDBPath = "<backup db filename>"; // From SD directory.
File backupDB = new File(data, currentDBPath);
File currentDB = new File(sd, backupDBPath);
FileChannel src = new FileInputStream(backupDB).getChannel();
FileChannel dst = new FileOutputStream(currentDB).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
Toast.makeText(getApplicationContext(), "Import Successful!",
Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Import Failed!", Toast.LENGTH_SHORT)
.show();
}
}
private void exportDB() {
try {
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite()) {
String currentDBPath = "//data//" + "<package name>"
+ "//databases//" + "<db name>";
String backupDBPath = "<destination>";
File currentDB = new File(data, currentDBPath);
File backupDB = new File(sd, backupDBPath);
FileChannel src = new FileInputStream(currentDB).getChannel();
FileChannel dst = new FileOutputStream(backupDB).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
Toast.makeText(getApplicationContext(), "Backup Successful!",
Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Backup Failed!", Toast.LENGTH_SHORT)
.show();
}
}
