Try loadDataWithBaseUrl() instead of loadData(), supplying some bogus value for the base URL (e.g., fake://why/o/why/is/this/needed).

android Widget button tech

shared by Vincent Tsao on 08 Jul 10 - Cached
  • An App Widget uses a special display control called RemoteViews. Unlike a regular View, a RemoteViews control is designed to display a collection of View controls in another process. Consequently, you can't simply add a button handler because that code would run in your application process, not in the process displaying the RemoteViews object (in this case, the Home Screen process).
  • In order to handle user interaction with an App Widget, the following tasks must be performed: Set a unique click handler for each App Widget control Have the click handler send a command to a registered receiver Process the command received and perform any action necessary Update the App Widget to reflect the changes

How to update the GUI in Push/C2DM sample from advandroid book? - cw-android | Google G... - 0 views

android C2dm Broadcast Notification

shared by Vincent Tsao on 18 Sep 10 - No Cached
  • > Now I just want to update the GUI from this method. > Can I somehow call a method in PushEndpointDemo.java? No, for two reasons: 1. Because C2DMReceiver is a manifest-registered BroadcastReceiver and therefore has no access to any activities 2. There might not be an activity, since you have no control over the timing of when the C2DM message is received (e.g., the user pressed BACK, the user pressed HOME) > Do I need a Broadcast Intent to do this? Possibly. -- If you want to update an activity or else ignore the message, have C2DMReceiver send out a private broadcast, picked up by a receiver registered via registerReceiver() in the activity -- If you want to update an activity or else raise a notification, have C2DMReceiver send out an ordered broadcast, as described here: http://commonsware.com/blog/2010/08/11/activity-notification-ordered-... -- If you want to update a database, call startActivity() on an IntentService, and have it do the database I/O, plus possibly broadcast an Intent to update an activity/raise a notification.

  • 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

android google AdSense

shared by Vincent Tsao on 27 May 10 - Cached
  • 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。

  • 把这句抄下来了，大家以后小心了。 Ad Behavior AdSense code may not be altered, nor may the standard behavior, targeting or delivery of ads be manipulated in any way that is not explicitly permitted by Google. For instance, clicking Google ads may not result in a new browser window being launched. 我猜是不是可以找google总部投诉一下这个部门

How to implement a Button on an Android Widget - Stack Overflow - 0 views

android Widget button tech

shared by Vincent Tsao on 08 Jul 10 - Cached
  • I am just getting started with Android development and I have created a nice little widget that displays some info on my home screen. However, I now want to implement a Button on my widget that updates the info in my widget TextView.
  • Solved - I can confirm that an Activity is NOT needed if you want create a Button to update an Android AppWidget. I have been able to implement my AppWidgetProvider class such that it registers an android.appwidget.action.APPWIDGET_UPDATE intent-filter with the Broadcast receiver in the AndroidManifest.xml, which then fires the onUpdate event in the AppWidgetProvider class (which in turn then runs the UpdateService).
  • The UpdateService in my AppWidgetProvider class then uses onHandleIntent to run a private buildUpdate method - which registers the onClick event with a call to setOnClickPendingIntent as follows:
  • ...1 more annotation...
  • // set intent and register onclickIntent i = new Intent(this, MyWidget.class);PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0);updateViews.setOnClickPendingIntent(R.id.update_button,pi);

android search tech

shared by Vincent Tsao on 02 Aug 10 - No Cached
  • If your data is stored in a SQLite database on the device, performing a full-text search (using FTS3, rather than a LIKE query) can provide a more robust search across text data and can produce results significantly faster.
  • If your data is stored online, then the perceived search performance might be inhibited by the user's data connection. You might want to display a spinning progress wheel until your search returns.
  • <?xml version="1.0" encoding="utf-8"?><searchable xmlns:android="http://schemas.android.com/apk/res/android"    android:label="@string/app_label"    android:hint="@string/search_hint" ></searchable>

Supporting Multiple Screens | Android Developers - 0 views

android Multiple Resolution tech

shared by Vincent Tsao on 23 Mar 10 - Cached
  • The density of a screen is important because, other things being equal, a UI element (such as a button) whose height and width are defined in terms of screen pixels will appear larger on the lower density screen and smaller on the higher density screen.
  • The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, the baseline density assumed by the platform (as described later in this document). At run time, the platform transparently handles any scaling of the dip units needed, based on the actual density of the screen in use. The conversion of dip units to screen pixels is simple: pixels = dips * (density / 160). For example, on 240 dpi screen, 1 dip would equal 1.5 physical pixels. Using dip units to define your application's UI is highly recommended, as a way of ensuring proper display of your UI on different screens.
