  • Android browser touch events stop display being updated inc. canvas/elements - How to work around?

    - by Ed Kirk
    On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though). Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll. A similar question has been asked here: Does Android browser lock DOM on touchStart? but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question. Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png. https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions. Update It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic. I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.

  • How can I learn Android?

    - by Vijay Kansal
    I am a newcomer to Android. I know the C And C++ programming languages, but I do not know Java . I want to learn Android right from basics, but I could not find any relevant link or e-book that can help me. Can I begin to learn Android without knowing Java or should i go to learn Java first? From where should I learn Android which should be easy to grasp and learn for a newcomer like me.

  • Implementing In App purchases in Android?

    - by hgpc
    It looks like Android won't natively support in-app purchases for a while, and when it does there might be a huge user base with devices that don't support them. What's the best way to implement iPhone-like (additional content or services) in-app purchases in Android using the Android Market if possible? The solution should consider in particular: For all kinds of in-app purchases: Android Market's 24-hour cancellation policy For consumables/non-consumables: storage of additional content (ie: use precious application memory to avoid piracy, or use SD card to avoid bloating application memory) Thanks!

  • [Android] Show default selection color for custom listview

    - by Diego
    Hello, I have a listview with a custom BaseAdapter. Each row of the listview has a TextView and a CheckBox. The problem is when I click (or touch) any row, the textview foreground becomes gray, instead of the default behavior (background - green, textview foreground - white). Here is the code: row.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/layout"> <TextView android:id="@+id/main_lv_item_textView" style="@style/textViewBig" android:layout_alignParentLeft="true"/> <CheckBox android:id="@+id/main_lv_item_checkBox" style="@style/checkBox" android:layout_width="wrap_content" android:layout_alignParentRight="true"/> </RelativeLayout> Custom Adapter: public class CustomAdapter extends BaseAdapter { private List<Profile> profiles; private LayoutInflater inflater; private TextView tvName; private CheckBox cbEnabled; public CustomAdapter(List<Profile> profiles) { this.profiles = profiles; inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public int getCount() { return profiles.size(); } public Object getItem(int position) { return profiles.get(position); } public long getItemId(int position) { return position; } public View getView(final int position, View convertView, ViewGroup parent) { View row = inflater.inflate(R.layout.main_lv_item, null); final Profile profile = profiles.get(position); tvName = (TextView) row.findViewById(R.id.main_lv_item_textView); registerForContextMenu(tvName); cbEnabled = (CheckBox) row.findViewById(R.id.main_lv_item_checkBox); tvName.setText(profile.getName()); if (profile.isEnabled()) { cbEnabled.setChecked(true); } tvName.setOnClickListener(new OnClickListener() { public void onClick(View v) { Bundle bundle = new Bundle(); bundle.putString(PROFILE_NAME_KEY, profile.getName()); Intent intent = new Intent(context, GuiProfile.class); intent.putExtras(bundle); startActivity(intent); } }); tvName.setOnLongClickListener(new OnLongClickListener() { public boolean onLongClick(View v) { selectedProfileName = ((TextView) v).getText().toString(); return false; } }); cbEnabled.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (!profile.isEnabled()) { for (Profile profile : profiles) { if (profile.isEnabled()) { profile.setEnabled(false); Database.getInstance().storeProfile(profile); } } } profile.setEnabled(isChecked); Database.getInstance().storeProfile(profile); updateListView(); } }); return row; } } Any help would be appreciated.

  • Why does the Mac OS X firewall dialog recurringly pop-up and disappear by itself (without letting me

    - by Chris W. Rea
    From time to time, I'll be on my Macbook using a program that accesses the network – whether Firefox, or Sony's Reader Library – really, it seems like it could happen with any program that accesses the network – and for no reason that I can discern so far (that is, it happens intermittently) the OS X firewall dialog pops up to ask me the question: Except it doesn't actually let me click anything before it disappears! That is: the dialog pops up, ... then goes away by itself a second later, then pops up again, ... then goes away by itself a second later, etc. It happens a few times before stopping. It wouldn't be so maddening to be interrupted if I could just be allowed to click "Allow" and make the darn thing go away for good. In Security preferences I have the firewall turned "On", and I would like to keep it that way. Has anybody seen this problem, found the source, and figured out a solution or workaround? Thank you.

  • How to reference a string from another package in a library using XML in Android?

    - by Garret Wilson
    The Android documentation tells me that I can access a string from another package by using the "package name", whatever that means: @[<package_name>:]<resource_type>/<resource_name> So in my manifest I want to access a string that I've placed in a separate library project, in the com.globalmentor.android package---that's where my R class is, after all: <activity android:label="@com.globalmentor.android:string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> That doesn't even compile. But this does: <activity android:label="@string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> Why? What does the Android documentation mean which it talks about the "package_name"? Why doesn't the first example work, and why does the second example work? I don't want all my resource names merged into the same R file---I want them partitioned into packages, like I wrote them.

  • How to run a widget inside of an activity in Android?

    - by user220755
    I have a widget built to give the user the chance to choose the date (I did not build it, I am building on top of an open source software). Now, I need to display this widget inside of a class that extends the activity class in Android. Let me show some code. Let us say this is the activity class: public class RandomClass extends Activity { public void onCreate(Bundle savedInstanceState) { // I want to run the widget here when the class is created // (the activity is created) } } The widget i want to run is a widget that lets the user choose the date. I know I code use one of Android's activities but I need to build on top of the code so I have to run it inside of the activity class I created. Sorry if this is not clear, ask any questions and i will be more than glad to answer them and clarify.

  • Testcase with multitouch on Android?

    - by makke
    The TouchUtils class in the android documentation has functions like drag() [http://developer.android.com/intl/de/reference/android/test/TouchUtils.html#drag(android.test.InstrumentationTestCase,%20float,%20float,%20float,%20float,%20int)], but they do not support multi touch gestures, like a two finger swipe. Looking at the MotionEvent.obtain() methods, there does not seem to be any way of invoking a "virtual" multi touch event from a testcase. Anyone has got it working?

  • Unfortunately App stopped when destroying SupportMapFragment

    - by user1408341
    I have the following problem. I have three fragments which are hosted in a TabHost. When I'm working with the app everything works fine. Now I like to end the app when the user hits the back button. Instead of terminating without errors I get the message Unfortunately App stopped. Then I said to myself something is wrong with the onDestroy() method of the FragmentActivity or with the onDestroyView method() of the Fragment. The problem is I cannot debug the point where the app crash. I get only the error:Fatal signal 11 (SIGSEGV). I then removed one by one each Fragment to identify which fragment causes the error. I could identify the fragment that I named BasicMapFragment. Something is wrong there. The code: public class BasicMapFragment extends SupportMapFragment implements LocationListener { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = super.onCreateView(inflater, container, savedInstanceState); //removeAllMarkers(); //setupGps(); //setupMap(); //setupMarkersFromModel(); //registerListeners(); return view; } } I commented out all my self written code to isolate the place where the error occurs. @Override public void onDestroy() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy called"); super.onDestroy(); } public void onDestroyView() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy view called"); super.onDestroyView(); } When I press the back button now the onDestroy() method of my FragmentActivity is first called like expected. Then the onDestroyView method is called on my BasicMapFragment class. At the end the onDestroy method is called - and then the application crash. Here is my layout file: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/> </FrameLayout> Resume: - Map is showed - I can work with the app. - When I leave out the BasicMapFragment the app finish without error. - When I add the BasicMapFragment the app returns an error when I press the back button Is there something that I have forgot to implement? Have somebody had the same trouble?

  • Hot to implement grails server-side-triggered dialog, or how to break out of update region after AJA

    - by werner5471
    In grails, I use the mechanism below in order to implement what I'd call a conditional server-side-triggered dialog: When a form is submitted, data must first be processed by a controller. Based on the outcome, there must either be a) a modal Yes/No confirmation in front of the "old" screen or b) a redirect to a new controller/view replacing the "old" screen (no confirmation required). So here's my current approach: In the originating view, I have a <g:formRemote name="requestForm" url="[controller:'test', action:'testRequest']", update:"dummyRegion"> and a <span id="dummyRegion"> which is hidden by CSS When submitting the form, the test controller checks if a confirmation is necessary and if so, renders a template with a yui-based dialog including Yes No buttons in front of the old screen (which works fine because the dialog "comes from" the dummyRegion, not overwriting the page). When Yes is pressed, the right other controller & action is called and the old screen is replaced, if No is pressed, the dialog is cancelled and the "old" screen is shown again without the dialog. Works well until here. When submitting the form and test controller sees that NO confirmation is necessary, I would usually directly redirect to the right other controller & action. But the problem is that the corresponding view of that controller does not appear because it is rendered in the invisble dummyRegion as well. So I currently use a GSP template including a javascript redirect which I render instead. However a javascript redirect is often not allowed by the browser and I think it's not a clean solution. So (finally ;-) my question is: How do I get a controller redirect to cause the corresponding view to "break out" of my AJAX dummyRegion, replacing the whole screen again? Or: Do you have a better approach for what I have in mind? But please note that I cannot check on the client side whether the confirmation is necessary, there needs to be a server call! Also I'd like to avoid that the whole page has to be refreshed just for the confirmation dialog to pop up (which would also be possible without AJAX). Thanks for any hints!

  • how can i edit the action of the buttons in the dialog box in jquery?

    - by noob
    this code is from the demo of modal confirmation from jquery's site. <script type="text/javascript"> $(function() { $("#dialog").dialog({ bgiframe: true, resizable: false, height:140, modal: true, overlay: { backgroundColor: '#000', opacity: 0.5 }, buttons: { 'Yes': function() { $(this).dialog('close'); }, 'No': function() { $(this).dialog('close'); } } }); }); </script> <div class="demo"> <div id="dialog" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered.

  • How do you manage the testing of your Android software on physical devices?

    - by Philip Regan
    I'm in charge of managing mobile application development at my company, and I am currently building a mobile device "library" for testing. Essentially, we want to have a representative device in-house for each of the OSes we are developing for, currently iOS (iPhone-only), Blackberry, and Android. Simulators only go so far, but I'm placing into the process a step to test software on the devices themselves. The problem we're finding is with Android. I don't think any of us here ever really understood just how fragmented the whole platform is until we started looking at devices to acquire. We are going to wait until v2.3 of Android is released, but which products to choose? Do we go by the most popular by market share? Do we get a small range of products by specs from least to most powerful overall? We're trying to avoid having to manage a dozen different devices to test each app, if not because of cost if only for the repeated time sink. How do you manage the testing of your Android software on physical devices?
