思路转换的失败

针对的用户群体动辄就是全球目标用户，在商业判断和分析上，最基础的一个考量就是用户群体和业务模式的总量的收益是否足够大，对用户群体的研究和商业判断分析完全根据市场分析报告和数据来做判断。因此，不可避免地在程序创意思路上会沿用以前的工作思路和分析方法。 在考虑Android上的创意的同时，不自觉地就考虑和分析了如下几个方面的问题： 1. 是否为用户所必需？ 2. 技术上是否领先？ 3. 程序的粘性是否足够？ 4. 用户群体是否足够大？ 因此，沿用这个思路，不可避免地就会往大的应用和大的服务上去思考和做出判断。

经过反复地反省和对比，初步得出了这样的失败教训： 1. 对于个人开发者和小型团队来说，不适合做过于基础的程序。操作的模式和理念上的创新与用户的接受度有相当的距离。这样的事情只有大公司才有财力和可能进行推广。比如说手机生产商，他们可以通过预置的方式进行推广。而对个人开发者来说，得先证明你的想法是成功的，不能假设一个会成功的需求和应用，然后卖给设备厂商。 2. 个人开发者和小型团队不适合做大的程序，尤其是开发时间不要超过2个月。4个人，3个月的时间，对于一个小团队来说 ，是相当宝贵的。这不仅仅是时间和金钱的问题，更多的是信心问题。 3. 用户能否真正接受你的想法，是一个关键性的问题。设想和推导都很完美，唯独缺了用户是否真正喜欢和接受这一条，又没有方法进行快速地验证和试错，基本上不能成功。

google最后给的判决书： Hi, After further review from our abuse team we have confirmed that your account that was closed was modifying the ad behavior which is strictly prohibited as stated in the AdSense policies. These types of violations pose a significant risk to advertisers and for this reason we can no longer work with you through any partnering AdSense account or product offering. This will be the final communication about this issue. Please do not reply to this email as you will not receive a response. Thank you for your understanding. Google AdSense 我们自始至终都不知道原因。

我Google了下 "modifying the ad behavior " 就是指你修改了 Google提供的 adsense js code 或者 sdk 唯一有可能的就是这里了 GoogleAdView adView = (GoogleAdView) activity.findViewById(R.id.ad<http://r.id.ad/> ); if (adView != null) { View vc = adView.getCurrentView(); if (vc instanceof WebView) { ((WebView) vc).destroy(); } View vn = adView.getNextView(); if (vn instanceof WebView) { ((WebView) vn).destroy(); } } 因为用了adsense之后 我们的程序老是crash 从stack trace看是因为Google adsense sdk 引起的. 资源没有释放. 然后去Adsense的那个mail list AFMA 问了 碰到2个都有同样问题的 然后有人给了个code 因为adsense sdk没有destroy ad view  所以要手动destroy下 我们就在每个有ads的activty的 onDestroy 加上这段 就好了 程序没有crash了 结果就被搞了 连负责我们android adsense sales都事先不知道 adsense team就直接把我们封了 还在beta 测试阶段的东西 还有bug  我们只是加了这个保证他资源正常释放不会影响到我们程序 结果就挂了 而且Google的态度巨NX无比 连个申述的途径都没有  只是给了个link类似事后调查

我刚刚给我的sale发了一封信： Hi Sunil, It has been long that I haven't talked to you. I have a question, when I went to the application register page, I found the page layout was changed and some of my apps were gone. For example UK TV Guide, Australia TV Guide, etc. Also, the published status are all "false". I am confused because I am still seeing my ads are clicked in the daily report. Is there anything wrong? I am nervous because I just knew that an AdSense developer's account was disabled without any warning,  and the developers themselves don't know the reason. I don't want that happened on me so I really appreciate your comment. below is the letter in AFMA group. Looking forward to your reply. Thanks. Cheers, Luke 接下来我引用了superdroid的信。看看他怎么说吧。

If you're managing the cursor yourself the cleanest way to go is probably this: Cursor cursor = getContentResolver().query(...); try {     // read from the cursor and do stuff } finally {     if (cursor != null) cursor.close(); }

Another option if you still want to use Activity.managedQuery() is to get your information and then: stopManaging(cursor); cursor.close(); Cheers, Justin Android Team @ Google

Sunil回信了。 Hi Luke, Rest assured the apps are fine. We are migrating people over the new system and will let you know when it's complete. Showing false does not impact your earnings or account. 他只字未提Superdroid的事件。

OnScrollListner there is an example in the API demos.

You can try my EndlessAdapter for that: http://github.com/commonsguy/cwac-endless

The fact that sub-menus don't support icons. http://developer.android.com/intl/fr/guide/topics/ui/menus.html <http://developer.android.com/intl/fr/guide/topics/ui/menus.html> *Icon Menu * This is the collection of items initially visible at the bottom of the screen at the press of the MENU key. It supports a maximum of six menu items. *These are the only menu items that support icons* and the only menu items that *do not* support checkboxes or radio buttons.

Try to use PopUpWindow <http://developer.android.com/reference/android/widget/PopupWindow.html>class. Here you have an example<http://www.anddev.org/how_to_create_a_popupwindow-t1259.html>

// Get display for detecting the phone orientation display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); // Get the orientation int orientation = display.getOrientation();

android.view.Display class provide a simple way to determine the phone orientation.
