android隐藏某apk主菜单 （一）

最近在弄一个需求，要求硬件支持ATV的话，就将ATV主菜单显示出来，否则不显示ATV主菜单。

查了些资料，最开始在launcher里修改，可以实现此功能。在launcher里修改方法：

当launcher在加载所有apk时，判断硬件是否支持atv,若支持，请查看代码：

这是在2.3.5上修改的：

packages/apps/hylauncher/src/com/android/hylauncher

public ApplicationsAdapter(Context context, ArrayList<ApplicationInfo> apps, AppCatalogueFilter filter) {super(context, 0, apps);mCatalogueFilter = filter;mInflater = LayoutInflater.from(context);// HY: Load textcolor and bubble color from themeString themePackage = AlmostNexusSettingsHelper.getThemePackageName(getContext(), Launcher.THEME_DEFAULT);                      if (!themePackage.equals(Launcher.THEME_DEFAULT)) {Resources themeResources = null;try {themeResources = getContext().getPackageManager().getResourcesForApplication(themePackage);} catch (NameNotFoundException e) {// e.printStackTrace();}if (themeResources != null) {int textColorId = themeResources.getIdentifier("drawer_text_color", "color", themePackage);if (textColorId != 0) {mTextColor = themeResources.getColor(textColorId);useThemeTextColor = true;}mBackground = IconHighlights.getDrawable(getContext(),IconHighlights.TYPE_DRAWER);    try{    themeFont=Typeface.createFromAsset(themeResources.getAssets(), "themefont.ttf");    }catch (RuntimeException e) {// TODO: handle exception}}}}

在上面这个函数中String themePackage = AlmostNexusSettingsHelper.getThemePackageName(
getContext(), Launcher.THEME_DEFAULT); 后加上判断条件：

try {            if (IfExistFile("/sys/class/atv/nmi/dev")) {                is_atv_exist = true;                Log.v(TAG, "is_atv_exist = " + is_atv_exist);            } else {                is_atv_exist = false;                Log.v(TAG, "is_atv_exist = " + is_atv_exist);            }            }catch (FileNotFoundException e) {                // TODO Auto-generated catch block                e.printStackTrace();                is_atv_exist = false;                Log.v(TAG, "the atv is not  exist");            }

这里用到了一个判断文件是否存在的函数：

private boolean IfExistFile(String fileName) throws FileNotFoundException {        // TODO Auto-generated method stub        File file = new File(fileName);        if (file.exists()) {            return true;        } else {            return false;        }    }

下面要找到加载所有apk的地方：

@Overridepublic void add(ApplicationInfo info) {//check allItems before added. It is a fix for all of the multi-icon issue, but will //lose performance. Anyway, we do not expected to have many applications.synchronized (allItems) {/*if (!allItems.contains(info)) {changed = true;allItems.add(info);Collections.sort(allItems,new ApplicationInfoComparator());}*/int count=allItems.size();boolean found=false;            boolean update=false;for(int i=0;i<count;i++){ApplicationInfo athis=allItems.get(i);if(info.intent.getComponent()!=null){if(athis.intent.getComponent().flattenToString().equals(info.intent.getComponent().flattenToString())){                        if (0 != athis.title.toString().compareTo(info.title.toString())) {                            athis.title = info.title;                            update = true;                        }found=true;break;}}}if(!found){allItems.add(info);Collections.sort(allItems,new ApplicationInfoComparator());if(SprdFeatureUtils.SPRD_APP_HYLAUNCHER_ICON_SORT){HyLauncherFunctionIconSort();}updateDataSet();} else if (update) {Collections.sort(allItems,new ApplicationInfoComparator());if(SprdFeatureUtils.SPRD_APP_HYLAUNCHER_ICON_SORT){HyLauncherFunctionIconSort();}updateDataSet();mUpdateViewCache = true;}} }

添加上符合判断条件的操作：不让加载此apk菜单：

if(info.intent.getComponent().getClassName().equals("com.example.onekeyclearrecentslist.ClearMainActivity") && !is_atv_exist){
   if(info.intent.getComponent().getClassName().equals("com.nmi.test.test") && !is_atv_exist){
   Log.v(TAG, "dont add the atv application");
       return;
   }

加完之后就是以下的样子：

@Overridepublic void add(ApplicationInfo info) {//check allItems before added. It is a fix for all of the multi-icon issue, but will //lose performance. Anyway, we do not expected to have many applications.synchronized (allItems) {/*if (!allItems.contains(info)) {changed = true;allItems.add(info);Collections.sort(allItems,new ApplicationInfoComparator());}*/int count=allItems.size();boolean found=false;            boolean update=false;for(int i=0;i<count;i++){ApplicationInfo athis=allItems.get(i);if(info.intent.getComponent()!=null){if(info.intent.getComponent().getClassName().equals("com.example.onekeyclearrecentslist.ClearMainActivity") && !is_atv_exist){    if(info.intent.getComponent().getClassName().equals("com.nmi.test.test") && !is_atv_exist){    Log.v(TAG, "dont add the atv application");        return;    }else if(athis.intent.getComponent().flattenToString().equals(info.intent.getComponent().flattenToString())){                        if (0 != athis.title.toString().compareTo(info.title.toString())) {                            athis.title = info.title;                            update = true;                        }found=true;break;}}}if(!found){allItems.add(info);Collections.sort(allItems,new ApplicationInfoComparator());if(SprdFeatureUtils.SPRD_APP_HYLAUNCHER_ICON_SORT){HyLauncherFunctionIconSort();}updateDataSet();} else if (update) {Collections.sort(allItems,new ApplicationInfoComparator());if(SprdFeatureUtils.SPRD_APP_HYLAUNCHER_ICON_SORT){HyLauncherFunctionIconSort();}updateDataSet();mUpdateViewCache = true;}} }

编译此模块，push到手机里，验证是否还会有atv菜单。
