my first idea creating txt file write select, , later insert again.

but believe "problem" don't know if possible copy database , paste in sd card backup, , copy sd card , paste in path of database restore non root devices.

here code make 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>"; // 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();      } }
