Android 遍歷手機應用，跳轉應用市場詳情頁面

首先遍歷手機內應用，找到須要的應用包名：

    /**
     * 遍歷手機內應用包名
     * @param context
     */
    public static void loadApps(Context context) {
        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        List<ResolveInfo> apps = context.getPackageManager().queryIntentActivities(intent, 0);
        //for循環遍歷ResolveInfo對象獲取包名和類名
        for (int i = 0; i < apps.size(); i++) {
            ResolveInfo info = apps.get(i);
            String packageName = info.activityInfo.packageName;
            CharSequence cls = info.activityInfo.name;
            CharSequence name = info.activityInfo.loadLabel(context.getPackageManager());
            Log.e("wgh！！！！！", name + "----" + packageName + "----" + cls);
        }
    }

對包名進行應用市場詳情頁面跳轉：

    /**
     * 啓動到app詳情界面
     *
     * @param appPkg
     *            App的包名
     * @param marketPkg
     *            應用商店包名 ,若是爲""則由系統彈出應用商店列表供用戶選擇,不然調轉到目標市場的應用詳情界面，某些應用商店可能會失敗
