用Delphi xe6或xe7如何编安卓手机mp3播放程序？
或者是视频播放程序？

在win7、64位上可以编制windows上述的程序。

我已经用了xe7，请具体说一说在xe7上如何用第三方控件？

今天用XE7及Mediaplsyer控件与Android手机HTC连接运行。结果出现：
Go Up to Android Mobile Application Development
Android target platform with no Android emulator or Android deviceThe Target node within the Android target platform node in the Project Manager shows:
A list of the existing Android emulators installed on your PC, regardless of whether they are running or not.
A list of Android devices connected by USB to your PC, as long as you enable USB debugging and configure your PC to detect your device.
If the Project Manager does not show any Android emulator or device in the Target node within the Android target platform node, or if a device connected to your PC or an emulator installed in your PC does not show up:
Ensure that you have an Android SDK in the SDK Manager. Add an Android SDK if you do not have one already.
Right-click the Target node and select Refresh. A pair of green arrows should appear over the folder icon, indicating that the refresh operation is in progress (). If the green arrows disappear and nothing happens, read the next bullets.
If an expected Android device does not show up, see Enabling USB Debugging on an Android Device and Configuring Your System to Detect Your Android Device.
If an expected Android emulator does not show up, see Creating an Android Emulator.
If an expected Android emulator that is installed but not running does not show up, open the SDK Manager and check in the SDK Properties of your Android SDK that the value of the Android location field is correct.
If an expected Android device does not show up, or if a running Android emulator shows up as not running, open the SDK Manager and check in the SDK Properties of your Android SDK that the value of the Adb location field is correct.
大意是要安装一个Android device程序。

Delphi XE101.2 MediaPlayer1 安卓手机播放MP4程序
主要控件
MediaPlayer1
MediaPlayerControl1 (MediaPlayer 属性:MediaPlayer1)
ToolBar1
Button1
1 new-》Muliti-Device Application-Delphi
2 MediaPlayer1
3 MediaPlayerControl1
4 ToolBar1-》Button1
MediaPlayer1.FileName := TPath.GetDocumentsPath + PathDelim + 'zzw2.mp4';
MediaPlayer1.Play;
Remote Path下面用鼠标点下向的箭头出现assets\internal\选择
5 建一个文件夹A2
运行程序后,会出现Android->Debug->dyg02(我起的程序运行名,自己可以随意起)
->assets->internal
选择.\assets\internal\(注意有.)
把Mp4的文件复制到这里.(非常重要的第一条)
6 非常重要的第二条
从project->deployment处添加Mp4的文件
这样运行程序就可以运行播放Mp4了。
7 我的手机是:金利F100
8 在文件开头
implementation
{$R *.fmx}
输入以下文字:也是非常重要
uses
System.iOUtils;
以上程序已经在金利手机上成功播放MP4了.
