Android Studio 0.8.2+ and above, could easily import modules. Thanks to TGMCains answer, is simplified, by using Android Studio itself to import OpenCV as a module.
- Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
- Import OpenCV to Android Studio, From File -> Import Module, choose sdk/java folder in the unzipped opencv archive.
- Update build.gradle under imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and 4) targetSdkVersion.
- Add module dependency by Application -> Module Settings, and select the Dependenciestab. Click + icon at bottom, choose Module Dependency and select the imported OpenCV module.
- Copy libs folder under sdk/native to Android Studio under app/src/main.
- In Android Studio, rename the copied libs directory to jniLibs and we are done.
Step (6) is since Android studio expects native libs in app/src/main/jniLibs instead of older libs folder. For those new to Android OpenCV, don't miss below steps
- include
static{ System.loadLibrary("opencv_java"); } - For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.
OpenCV written is in C/C++. Java wrappers are
- Android OpenCV SDK - OpenCV.org maintained Android Java wrapper. I suggest this one.
- OpenCV Java - OpenCV.org maintained auto generated desktop Java wrapper.
- JavaCV - Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.

敲了几晚SnakeGo, 原型出来? 大家来看看不...
不错, q货是---贪吃?..哈哈...别? q还是原? 好玩的在后面?..(以我敲字速度, 大约再等不到六个月应该可以完成了...)
今天q里记录下用LIBGDXq程中碰到的两个问题:
1. 调整屏幕比例;
2. Ud观察镜头;
一, 调整屏幕比例
LIBGDX是跨q_? 一大好处就是直接在PC上测? 那是非常的方? 但这有两个问题需要考虑, 一, 手机?280x768, 但我PC只有1280x1024? 而且真要开个跟手机一样大的一样大的屏幕, 那还怎么看log输出? 二就是不同的手机有着不同的分辨率, 长宽比也不一? 那怎么保证囑Ş不变形呢?
q个问题不难解决, 只需要在屏幕寸发生变化? 即resize()(W一ơ启动也会调用此函数)? 重新调整镜头(Camera)的参数即? 如下代码:
@Override public void resize(int width, int height) { Vector2 size = Scaling.fit.apply(WIDTH, HEIGHT, width, height); camera = new OrthographicCamera(size.x, size.y); camera.update(); batch.setProjectionMatrix(camera.combined); int viewportX = (int)(width - size.x) / 2; int viewportY = (int)(height - size.y) / 2; int viewportWidth = (int)size.x; int viewportHeight = (int)size.y; Gdx.gl.glViewport(viewportX, viewportY, viewportWidth, viewportHeight); super.resize(width, height); }
q里采用的是重新创徏camera实例的方? 另外用改变已有camera实例的参数方式也是一L. 很简? 而且q样一ơ就解决了上面两个问?-- PCZ使用M寸的窗? 都可以获得跟讄{比例的H口, 手机上亦是如? ?a href="http://m.shnenglu.com/codejie/category/20828.html">I;P是采用的这U方式来保持其在L手机上都?280:768的比?
q种Ҏ只是改变?视图'的大? 但ƈ不会改变其中的图形的大小, q样Z保持囑Ş昄比例, 需要在输出囑Ş时做相应的比例放~? 可以在resize()获得q个比例, 染在囑Ş输出时用这个比?
screenScaling = new Vector2((size.x / WIDTH), (size.y / HEIGHT));
...
...
batch.draw(img, (- WIDTH / 2) * screenScaling.x, (- HEIGHT / 2) * screenScaling.y, WIDTH * screenScaling.x, HEIGHT * screenScaling.y);? Ud观察镜头
在SnakeGo? Z不让Snake'跑出'屏幕, 需要镜头camera跟Snake本n保持'同步'Ud, q样看v来Snake保持在屏q的中间, 但其它Object是移动的. Ҏ'相对q行'原理, 使整个看h像是Snake在Object中穿? 所? Udcamaera是必ȝ, 代码也简? 如下:
...
final OrthographicCamera camera = game.getCamera();
camera.translate(0.0f, 32.0f, 0.0f);
camera.update();
game.getSpriteBatch().setProjectionMatrix(camera.combined);
...

Fragment代替Activity的好处很?比如没有不同UI间切换的'闪动',视觉是上也有加快昄的效?但这U效果也是有代h? 大量Activity方式下的工作,在Fragment?不得不自己来实现,比如UI?压栈'{等.
q里记录下EL实现?到的跟Fragment相关的问? (Fragment相关文?a >官方链接在这?/a>)
1. 参数传?br /> Activity切换?可以在StartActivity()?通过Intent的方式将所需参数传递给下一个Activity. 但在Fragment方式下就不行?此时可?参考Fragment支持的setArguments()和getArguments(). EL中所有Fragment都承于BaseFragment,在显CFragment?使用设计的OnArgument()接口传递参?
fragment.onArguments(args);
fragmentManager.beginTransaction().show(fragment).commit();
fragmentManager.beginTransaction().show(fragment).commit();
2. 界面切换
FragmentManager是用于管理Fragment的类,通过内部的FragmentTranscation对象实现Fragment的加?昄/隐藏/U除{操? EL实现?使用FragmentSwitchercd装了FrangmentManager,以实现某些更灉|的Fragment理,比如某些Fragment在被切换是需要删?而其他的仅需要隐藏等操作.

3. Fragment的栈
Activity在切换时,通常情况下可以通过BACK键返回前一个Activity,是因为存在一??来存攑։面的Activity. Fragment也有栈的概念,但在操作上就需要自׃动调用了 -- Fragment隐藏?压栈; Fragment退出时,出栈.
private void hide(Type type) {
BaseFragment fragment = (BaseFragment) fragmentManager.findFragmentByTag(type.getTitle());
if (fragment != null) {
if (type.hasRemoved()) {
fragmentManager.beginTransaction().remove(fragment).commit();
} else {
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.addToBackStack(type.getTitle());
ft.hide(fragment);
ft.commit();
// fragmentManager.beginTransaction().hide(fragment).commit();
}
curType = null;
}
}
BaseFragment fragment = (BaseFragment) fragmentManager.findFragmentByTag(type.getTitle());
if (fragment != null) {
if (type.hasRemoved()) {
fragmentManager.beginTransaction().remove(fragment).commit();
} else {
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.addToBackStack(type.getTitle());
ft.hide(fragment);
ft.commit();
// fragmentManager.beginTransaction().hide(fragment).commit();
}
curType = null;
}
}
public boolean showPrevFragment() {
int count = fragmentManager.getBackStackEntryCount();
if (count > 0) {
String name = fragmentManager.getBackStackEntryAt(count - 1).getName();
fragmentManager.popBackStack();// .popBackStackImmediate();
Type type = Type.getType(name);
if (type != null) {
show(type);
return true;
}
}
return false;
}
int count = fragmentManager.getBackStackEntryCount();
if (count > 0) {
String name = fragmentManager.getBackStackEntryAt(count - 1).getName();
fragmentManager.popBackStack();// .popBackStackImmediate();
Type type = Type.getType(name);
if (type != null) {
show(type);
return true;
}
}
return false;
}
ȝ来说,Fragment要想用着方便,自己使用FragmentSwitcher和BaseFragment来封装下FragmentManager和Fragmentq是不错的选择.

My purpose is that get the UT line coverage report of source files by running the test file. I guess I should get the below report of line coverage, because I have called every functions of source file in test file, include the inline function and the normal function.
But after run test file, I got the report is just 50%, the inline function has not been covered. Why? Why it is not be covered? I am sure it is called in test file.
OK, Calming down. If it is not covered, there are two reason, one is that the inline function is not be called, of course it is impossible, because we did it. So the root cause must be the second one that gcov/lcov tools do not process those lines of inline function. Have any idea? gcov/lcov tools process all files with compilation parameters '-fprofile-arcs -ftest-coverage', so let's check makefile file again.
Look here, source files have the compilation paraments, but why normal function has been coverage, but inline function not?
$(SOURCE): %.o:%.c
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@ -fprofile-arcs -ftest-coverage
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@ -fprofile-arcs -ftest-coverage
Thinking again, as we knew, the difference between inline function and normal function is just that inline function will be inserted source code while compiling period. Yes, the answer is here! While compiling, the inline function is put into test file, but the test file has not '-fprofile-arcs -ftest-coverage' paramenter. So, so it was not covered.
$(TEST): %.o:%.c
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@
To fix it, just add the parameter to test file while compiling. OK, let's update the makefile file like the below line.
$(TEST): %.o:%.c
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@ -fprofile-arcs -ftest-coverage
gcc -MM -MF $(subst .o,.d,$@) -MT "$@ $(subst .o,.d,$@)" $<
gcc -c $< -o $@ -fprofile-arcs -ftest-coverage
Done, enjoy it!
