[2013.9.8网络首发]导入Android4.2源码里的Gallery2和Camera模块

（自带的，然后将新建CompatibilityInfoHolder.java。[备注：在有的版本上并没有遇到这个问题，有可能是android4.2将这个类去除了。]

package android.view;import android.content.res.CompatibilityInfo;/** @hide */ public class CompatibilityInfoHolder {private volatile CompatibilityInfo mCompatInfo = CompatibilityInfo.DEFAULT_COMPATIBILITY_INFO;public void set(CompatibilityInfo compatInfo) {if (compatInfo != null && (compatInfo.isScalingRequired()|| !compatInfo.supportsScreen())) {mCompatInfo = compatInfo;} else {mCompatInfo = CompatibilityInfo.DEFAULT_COMPATIBILITY_INFO;}}public CompatibilityInfo get() {return mCompatInfo;}public CompatibilityInfo getIfNeeded() {CompatibilityInfo ci = mCompatInfo;if (ci == null || ci == CompatibilityInfo.DEFAULT_COMPATIBILITY_INFO) {return null;}return ci;} }

12、 再次clean编译会报错：某个函数需要的api版本要大于11，当前最低版本为10.需修改AndroidManifest.xml文件，最低api版本为11，，目标版本为17，因为我们的手机是4.2对应级别为17。

13、 再次clean编译会报错：在ImageFilterSharpen.java函数里找不到forEach_root（）函数。通过对源码编译的输出路径out进行搜索，在/out/target/common/obj/APPS/GALLERY2_intermediates/src/com/android/Gallery3d/filtershow/filters文件夹下找到ScriptC_convolve3x3.java一共可以找到3份同名的文件，只有这个路径下的代码有forEach_root(Allocation, Allocation)接口。将此文件复制出来一份，粘贴到com.android.gallery3d.filtershow.filters下，将名字改为MyScriptC_convolve3x3.java，否则会跟gen文件下的文件重名，并在类的构造函数等其他地方更改名字，包名也要改。
