First, the mobile phone shortcut displays the Chinese name

project->options->Version Info-label(改成需要显示的中文名即可），但是需要安装到安卓手机才可以（IOS的没有试过）

Second, the use of sqllite storage Chinese

SqlLite中，字段类型要设置为nvarchar，保存时，有两种方式

1）用Post时，对中文的字段要进行UTF8转换

先用一个string变量转换一下（不转换的话Win32编译没有问题，Android编译时出错）

str_temp:=UTF8ENCODE(Trim(edit1.Text));,然后再赋值字段;

2)用ExecSql时

FdQuery.Sql.Text:=UTF8ENCODE(sql_text)

Third, use MESSAGEDLG format

if  MessageDlg(‘确认要退出吗?‘, TMsgDlgType.mtConfirmation, [TMsgDlgBtn.mbYes,Tmsgdlgbtn.mbNo], 0)=mrYes then

Iv. Withdrawal procedure

1）先加入一个单元:

Uses

{$IFDEF ANDROID}

  FMX.Platform.Android,

{$ENDIF ANDROID}

2)在FormCloseQuery事件中

If Messagedlg (' Do you want to quit? ‘,

Else

3）在FormClose中写入

{$IFDEF ANDROID}

{$ENDIF ANDROID}
