您可以将数据库复制到sdcard&之后你可以发邮件。
public void exportDatabse(String databaseName) {
try {
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite()) {
String currentDBPath = "//data//" + getPackageName() + "//databases//" +databaseName+ "";
String backupDBPath = "backupname.db";
File currentDB = new File(data, currentDBPath);
File backupDB = new File(sd, backupDBPath);
if (currentDB.exists()) {
FileChannel src = new FileInputStream(currentDB).getChannel();
FileChannel dst = new FileOutputStream(backupDB).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
}else{
System.out.println(":::");
}
}
} catch (Throwable e) {
e.printStackTrace();
}
}
希望这会有所帮助:)
