33了解普通的Android 程序开发可以非常有用的帮助Lazarus Android界面的开发。

55## 如何做...
66
77### 构建 NDK OpenGL 示例
88
99操作步骤如下:
1010
1111**第1步** - 下载和安装Android NDK, Android SDK 和 Ant.更多的信息在这儿: [[Android Interface/Using the Android SDK, Emulator and Phones|Android_Interface/Using_the_Android_SDK%2C_Emulator_and_Phones]]
1212
1313**第2步** - 安装已经编译好的FPC跨平台编译器. 说明信息在这儿: [[Android Interface|Android_Interface#Using_the_pre-compiled_compiler]]
1414
1515**第3步** - 下载最新的 lazarus-ccr sourceforge 代码:
1616
17-```
17+```text
1818svn co https://lazarus-ccr.svn.sourceforge.net/svnroot/lazarus-ccr lazarus-ccr
1919```
2020
2121或者如果你觉得这个文件夹太大那么你可以只下载此文件夹 lazarus-ccr/bindings/android-ndk
2222
2323**第4步** - 构建Pascal库文件(.SO)
2424
2525打开工程 lazarus-ccr/bindings/android-ndk/examples/opengltest/opengltest.lpi
2626
2727然后打开菜单 Project-\>Project Options-\>Paths 和右边的 "Libraries -Fl" 你可以看到如下所示:
2828
29-```
29+```text
3030/home/felipe/Programas/android-ndk-r5/platforms/android-9/arch-arm/usr/lib
3131```
3232
3333更改Android NDK路径为你的电脑中Andorid NDK的路径, 并且更改最低需要的Android API版本库文件夹路径为你的电脑的路径.
3434
3535现在使用Lazarus构建工程.
3636
3737**第5步** - 配置构建环境变量
3838
3939打开文件 opengltest/local.properties 查看这一行:
4040
41-```
41+```text
4242sdk.dir=/home/felipe/Programas/android-sdk-linux
4343```
4444
4545更改为你的Android SDK的路径, 注意 "/" 和 "\\"的区别
4646
4747**第6步** - 构建 APK 包
4848
4949打开一个终端(命令行)并且输入如下命令:
5050
5151cd lazarus-ccr/bindings/ndk/examples/opengltest/android ant debug
5252
5353成功构建的APK包位于这个文件夹中: opengltest/android/bin/
5454
5555**第7步** - 安装 APK 包
5656
5757如果在这一步你得到关于权限的错误信息，可以阅读这儿: [[Android Interface/Using the Android SDK, Emulator and Phones|Android_Interface/Using_the_Android_SDK%2C_Emulator_and_Phones#Recognition_of_devices_under_Linux]]
5858
5959使用命令行安装我们生成的APK包到手机：
6060
61-```
61+```text
6262cd opengltest/android
6363~/Programas/android-sdk-linux/platform-tools/adb install bin/OpenGLNDKTest-debug.apk
64642395 KB/s (107299 bytes in 0.043s)
6565 pkg: /data/local/tmp/OpenGLNDKTest-debug.apk
6666Success
6767```
6868
6969如果你得到一个包已经安装的错误信息那么你可以使用以下命令来卸载它：
7070
71-```
71+```text
7272~/Programas/android-sdk-linux/platform-tools/adb uninstall com.pascal.opengltest
7373```
7474
7575然后你可以在命令行中运行adb logcat，可以看到这个log记录, 它可以告诉你是如何在手机中添加一个新图标应用的:
7676
77-```
77+```text
7878~/Programas/android-sdk-linux/platform-tools/adb logcat
7979```
8080
8181### 读取屏幕尺寸
8282
8383First fill a TDisplayMetrics with the correct info:
8484
8585``` pascal
8686uses androidutil;
8787
8888var
8989 MyDisplayMetrics: TDisplayMetrics;
9090 Str: string;
9191 //
9292 lHeight, lWidth: Integer;
9393 xdpi, ydpi, lScreenSize: Single;
9494begin
9595 // ..
9696 // Objects
9797
9898 MyDisplayMetrics := TDisplayMetrics.Create;
9999 Activity.getWindowManager().getDefaultDisplay().getMetrics(MyDisplayMetrics);
100100```
101101
102102And then you can read it from the TDisplayMetrics:
103103
104104``` pascal
105105 lHeight := MyDisplayMetrics.heightPixels();
106106 lWidth := MyDisplayMetrics.widthPixels();
107107 xdpi := MyDisplayMetrics.xdpi();
108108 ydpi := MyDisplayMetrics.ydpi();
109109 lScreenSize := sqrt(sqr(lHeight / ydpi) + sqr(lWidth / xdpi));
110110 ldensity := MyDisplayMetrics.density();
111111 ldensityDpi := MyDisplayMetrics.densityDpi();
112112 scaledDensity := MyDisplayMetrics.scaledDensity();
113113```
114114
115115Note that lots of devices lie about the xdpi and ydpi, so don't trust the lScreenSize calculated above. Smartphones might report even 10 inches of screen size, while the correct is around 4.
116116
117117## 关于Android 设备的详细描述
118118
119119Since there are so many Android devices, it can be useful to keep track of some information about them. See also in the wikipedia Comparison of Android Devices [1](http://en.wikipedia.org/wiki/Comparison_of_Android_devices) and details about the processors in [2](https://wiki.mozilla.org/Mobile/Platforms/Android#System_Requirements).
