New		Line
1	+	其它请参考 [[Custom Drawn Interface/Android]]
2	+
3	+	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。
4	+
5	+	## 如何做...
6	+
7	+	### 构建 NDK OpenGL 示例
8	+
9	+	操作步骤如下:
10	+
11	+	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]]
12	+
13	+	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]]
14	+
15	+	第3步 - 下载最新的 lazarus-ccr sourceforge 代码:
16	+
17	+	`svn co `[`https://lazarus-ccr.svn.sourceforge.net/svnroot/lazarus-ccr`](https://lazarus-ccr.svn.sourceforge.net/svnroot/lazarus-ccr)` lazarus-ccr`
18	+
19	+	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
20	+
21	+	第4步 - 构建Pascal库文件(.SO)
22	+
23	+	打开工程 lazarus-ccr/bindings/android-ndk/examples/opengltest/opengltest.lpi
24	+
25	+	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:
26	+
27	+	`/home/felipe/Programas/android-ndk-r5/platforms/android-9/arch-arm/usr/lib`
28	+
29	+	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.
30	+
31	+	现在使用Lazarus构建工程.
32	+
33	+	第5步 - 配置构建环境变量
34	+
35	+	打开文件 opengltest/local.properties 查看这一行:
36	+
37	+	`sdk.dir=/home/felipe/Programas/android-sdk-linux`
38	+
39	+	更改为你的Android SDK的路径, 注意 "/" 和 "\\"的区别
40	+
41	+	第6步 - 构建 APK 包
42	+
43	+	打开一个终端(命令行)并且输入如下命令:
44	+
45	+	cd lazarus-ccr/bindings/ndk/examples/opengltest/android ant debug
46	+
47	+	成功构建的APK包位于这个文件夹中: opengltest/android/bin/
48	+
49	+	第7步 - 安装 APK 包
50	+
51	+	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]]
52	+
53	+	使用命令行安装我们生成的APK包到手机：
54	+
55	+	`cd opengltest/android`\
56	+	`~/Programas/android-sdk-linux/platform-tools/adb install bin/OpenGLNDKTest-debug.apk `\
57	+	`2395 KB/s (107299 bytes in 0.043s)`\
58	+	` pkg: /data/local/tmp/OpenGLNDKTest-debug.apk`\
59	+	`Success`
60	+
61	+	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：
62	+
63	+	`~/Programas/android-sdk-linux/platform-tools/adb uninstall com.pascal.opengltest`
64	+
65	+	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:
66	+
67	+	`~/Programas/android-sdk-linux/platform-tools/adb logcat`
68	+
69	+	### 读取屏幕尺寸
70	+
71	+	First fill a TDisplayMetrics with the correct info:
72	+
73	+	``` pascal
74	+	uses androidutil;
75	+
76	+	var
77	+	MyDisplayMetrics: TDisplayMetrics;
78	+	Str: string;
79	+	//
80	+	lHeight, lWidth: Integer;
81	+	xdpi, ydpi, lScreenSize: Single;
82	+	begin
83	+	// ..
84	+	// Objects
85	+
86	+	MyDisplayMetrics := TDisplayMetrics.Create;
87	+	Activity.getWindowManager().getDefaultDisplay().getMetrics(MyDisplayMetrics);
88	+	```
89	+
90	+	And then you can read it from the TDisplayMetrics:
91	+
92	+	``` pascal
93	+	lHeight := MyDisplayMetrics.heightPixels();
94	+	lWidth := MyDisplayMetrics.widthPixels();
95	+	xdpi := MyDisplayMetrics.xdpi();
96	+	ydpi := MyDisplayMetrics.ydpi();
97	+	lScreenSize := sqrt(sqr(lHeight / ydpi) + sqr(lWidth / xdpi));
98	+	ldensity := MyDisplayMetrics.density();
99	+	ldensityDpi := MyDisplayMetrics.densityDpi();
100	+	scaledDensity := MyDisplayMetrics.scaledDensity();
101	+	```
102	+
103	+	Note 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.
104	+
105	+	## 关于Android 设备的详细描述
106	+
107	+	Since 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).
