  • is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified

    - by user355859
    is it even possible to modify .apk, by adding additional class to .dex and re-packing with modified manifest.xml?? I know there are tools such as baksmali / smali to disassemble / re-assemble given classes.dex from .apk, but not sure limitation what could be modified from there on? I'm trying to add additional activity, to modify starting launcher activity (may be from androidmanifest.xml) from original apk, then re-pack and sign to make complete single .apk... all need to be done out of build time, no raw source or build structure visible, only .apk as input... ANY IDEA?

  • Can I increase a buttons onclick-area programmatically?

    - by sandis
    Sometimes I have a button in my UI that it is so small that it is difficult to click. My solution so far has been to add a transparent border around the button in photoshop. Just increasing the padding on the button does not work, since this will also stretch the image. Since it is kind of a fuss to open photoshop each time I want to change the clickable surface, is there any way to do this programmatically? I have tried placing a framelayout behind the button and make it clickable, but then the button wont change appearance on touch as it should. Ofcourse I could also add a ontouchlistener on the framelayout which changes the buttons appearance, but then it quite some code if I have several of those buttons. Cheers,

  • ListView in ArrayAdapter order get's mixed up when scrolling

    - by Dan B
    Hi, I have a ListView in a custom ArrayAdapter that displays an icon ImageView and a TextView in each row. When I make the list long enough to let you scroll through it, the order starts out right, but when I start to scroll down, some of the earlier entries start re-appearing. If I scroll back up, the old order changes. Doing this repeatedly eventually causes the entire list order to be seemingly random. So scrolling the list is either causing the child order to change, or the drawing is not refreshing correctly. What could cause something like this to happen? I need the order the items are displayed to the user to be the same order they are added to the ArrayList, or at LEAST to remain in one static order. If I need to provide more detailed information, please let me know. Any help is appreciated. Thanks.

  • How to test onLowMemory conditions?

    - by Samuh
    I have put some instructions in onLowMemory() callback and want to test the same. Is there a "direct" way to test onLowMemory function of the application subclass? Or will I have to just overload the phone by starting many apps and doing memory intensive tasks? Thanks.

  • Create NinePatch at Runtime

    - by Pedro Lopes
    Hello everybody! I have a business need to create the NinePatchDrawable objects at runtime, this is, an exterior .png image is received from a server and it has to be applied in a button's background (for example) as a nine patch. I have tried to create the NinePatchDrawable object, but the constructor asks me for a "byte[] chuck" that describes the patch. The thing is, I have no idea on how to build this chunck from a bitmap that does not have the 9patch information in it. Any ideas on this topic? Am I seeing the problem from a wrong perpective? Thanks!

  • Custom Preference Including EditText

    - by Shardul
    Hello, I am creating an custom preference which contains an EditText. The problem is when user clicks the EdiText for input suggestion box opens up and EditText looses focus. When EditText is clicked again for input, no problem occurs until 'blank space' is entered, which results in suggestion box and hence loss of focus. What I mean by suggestion box is the box which pops up when entering text in EditText

  • Dynamic ExpandableListView

    - by JLB
    Can anyone tell me how I can Dynamically add groups & children to an ExpandableListView. The purpose is to create a type of task list that I can add new items/groups to. I can populate the view with pre-filled arrays but of course can't add to them to populate the list further. The other method i tried was using the SimpleExpandableListAdapter. Using this i am able to add groups from a List but when it comes to adding children i can only add 1 item per group. public List<Map<String, String>> groupData = new ArrayList<Map<String, String>>(); public List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>(); public void addGroup(String group) { Map curGroupMap = new HashMap(); groupData.add(curGroupMap); curGroupMap.put(NAME, group); //Add an empty child or else the app will crash when group is expanded. List<Map<String, String>> children = new ArrayList<Map<String, String>>(); Map<String, String> curChildMap = new HashMap<String, String>(); children.add(curChildMap); curChildMap.put(NAME, "EMPTY"); childData.add(children); updateAdapter(); } public void addChild(String child) { List children = new ArrayList(); Map curChildMap = new HashMap(); children.add(curChildMap); curChildMap.put(NAME, child); curChildMap.put(IS_EVEN, "This child is even"); childData.add(activeGroup, children); updateAdapter(); }

  • Overriding Home button for a Car Home replacement app

    - by BigFwoosh
    I have been working on a replacement for the stock Car Home app for a bit, and I am completely stumped on how to override the Home button so that my app will be brought back to the foreground whenever the phone is docked. This is the way that Car Home works, so there must be a way. It seems that BroadcastReceivers won't work, because the intent that is broadcast whenever the Home button is pressed will still cause the default homescreen app to launch; I cannot prevent it. I can override the Home button from within my app, but that does me no good since this needs to work when the user is outside my app. Car Home also does not do anything weird like set itself as the default homescreen app while it's running (I checked the logcat to make sure). I've been really beating my head against the wall on this. Does anyone have any ideas, or can you at least point me in the right direction?

  • Parsing JSON with GSON

    - by Donn Felker
    I'm having some trouble with GSON, mainly deserializing from JSON to a POJO. I have the following JSON: { "events": [ { "event": { "id": 628374485, "title": "Developing for the Windows Phone" } }, { "event": { "id": 765432, "title": "Film Makers Meeting" } } ] } With the following POJO's ... public class EventSearchResult { private List<EventSearchEvent> events; public List<EventSearchEvent> getEvents() { return events; } } public class EventSearchEvent { private int id; private String title; public int getId() { return id; } public String getTitle() { return title; } } ... and I'm deserializing with the following code, where json input is the json above Gson gson = new Gson(); return gson.fromJson(jsonInput, EventSearchResult.class); However, I cannot get the list of events to populate correctly. The title and id are always null. I'm sure I'm missing something, but I'm not sure what. Any idea? Thanks

  • Enterprise Native Mobile Application Development

    - by ahsteele
    I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks. Note: As an organization we primarily use BlackBerry devices but are other platform curious.

  • PendingIntents in Notifications

    - by Mariano Kamp
    I would like to show a notification that displays the progress of an ongoing operation. That works well for me. But at the same time the remote view should contain cancel button to stop the ongoing operation. The usual content intent should still do something else, i.e. not cancel the ongoing operation. It seems though that I can only have one intent. I have to specify a contentIntent that is launched when clicking on the notification: If I don't specify that I get something along those lines: E/ActivityManager( 62): Activity Manager Crash E/ActivityManager( 62): java.lang.IllegalArgumentException: contentIntent required ... For the "cancel" button I set another intent: Intent cancelSyncIntent = new Intent("com.xyz.CANCEL_SYNC"); contentView.setOnClickPendingIntent(R.id.cancel_sync, PendingIntent.getBroadcast(context, 0, cancelSyncIntent, 0)); But this never works. I always get the content intent when the button is clicked. It looks like I cannot use buttons in remote views of notifications?! I could probably display a text: "<< Press to cancel operation ", but that seems rather heavy handed.

  • How to know preferred icon size for MenuItem?

    - by barmaley
    Hi folks, I my application I have one large PNG file containg hi-res image. Depending on situation I would like to use this image either as icon or as placeholder for ImageView. For MenuItem this image is too large, so I need to scale-down it to suitable size. I mean if it has to be displayed on large enough device like Samsung Galaxy Tab - I need to use one scale, for in small ones another, etc. I just noticed that for small-sized devices MenuItem icon is not scaled just cut - which is ugly. So the question is how should detect which is preferred size?

  • LogCat acting patchy

    - by OceanBlue
    The LogCat output in eclipse suddenly started weird. It sometimes shows all the output as expected. Other times it just doesn't show anything - is completely blank. After some internet research, I thought Mylyn plugin might be responsible. So I tried de-selecting "Mylyn Tasks UI" & "Mylyn Team UI" on eclipse Window -- Preferences -- General -- Startup and Shutdown -- programs that are started at startup. No Luck. Has anyone else encountered & solved this problem?

  • how to pause and stop a changing ImageView

    - by user270811
    hi, i have an ImageView in which the picture switches every 5s, i am trying to add a pause and resume button that can stop and restart the action. i am using a Handler, Runnable, and postDelay() for image switch, and i put the code on onResume. i am thinking about using wait and notify for the pause and resume, but that would mean creating an extra thread. so far for the thread, i have this: class RecipeDisplayThread extends Thread { boolean pleaseWait = false; // This method is called when the thread runs public void run() { while (true) { // Do work // Check if should wait synchronized (this) { while (pleaseWait) { try { wait(); } catch (Exception e) { } } } // Do work } } } and in the main activity's onCreate(): Button pauseButton = (Button) findViewById(R.id.pause); pauseButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { while (true) { synchronized (thread) { thread.pleaseWait = true; } } } }); Button resumeButton = (Button) findViewById(R.id.resume); resumeButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { while (true) { // Resume the thread synchronized (thread) { thread.pleaseWait = false; thread.notify(); } } } }); the pause button seems to work, but then after that i can't press any other button, such as the resume button. thanks.

  • Alarm not working if application gets killed

    - by Tobia Loschiavo
    Hi, I am trying to use an alarm to set my widget layout after some minutes. Everything works correctly in normal situation but, if I try to delete the process of my application, simulating a system kill, after the alarm is set, then no alarm is executed. Why? From documentation it seems that alarms are executed by AlarmManager service...so it should work. Thanks Tobia Loschiavo

  • Put an object in Handler message

    - by Tsimmi
    Hi! I need to download an image from the internet, in a different thread, and then send that image object in the handler message, to the UI thread. I already have this: ... Message msg = Message.obtain(); Bundle b = new Bundle(); b.putParcelable("MyObject", (Parcelable) object); msg.setData(b); handler.sendMessage(msg); And when I receive this message, I want to extract the object: ... public void handleMessage(Message msg) { super.handleMessage(msg); MyObject objectRcvd = (MyObject) msg.getData().getParcelable("IpTile"); addToCache(ipTile); mapView.invalidate(); } But this is giving me: ...java.lang.ClassCastException... Can anyone help? And by the way, is this the most efficient way to pass an object to the UI Thread? Thank you all!

  • Adding GestureOverlayView to my SurfaceView class, how to add to view hierarchy?

    - by Codejoy
    I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness. I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc . This all works great. I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have public class Panel extends SurfaceView implements SurfaceHolder.Callback, OnGesturePerformedListener { public Panel(Context context) { theContext=context; mLibrary = GestureLibraries.fromRawResource(context, R.raw.myspells); GestureOverlayView gestures = new GestureOverlayView(theContext); gestures.setOrientation(gestures.ORIENTATION_VERTICAL); gestures.setEventsInterceptionEnabled(true); gestures.setGestureStrokeType(gestures.GESTURE_STROKE_TYPE_MULTIPLE); gestures.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); //GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); } ... ... onDraw... surfaceCreated(..); ... ... public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList<Prediction> predictions = mLibrary.recognize(gesture); // We want at least one prediction if (predictions.size() > 0) { Prediction prediction = predictions.get(0); // We want at least some confidence in the result if (prediction.score > 1.0) { // Show the spell Toast.makeText(theContext, prediction.name, Toast.LENGTH_SHORT).show(); } } } } The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Panel p = new Panel(this); setContentView(p); } So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.

  • programmatically unset a default application

    - by dystroy
    I made a Home application and I'd like to offer the ability to exit it and unset it as the default application. Exit is easy (just starting an intent) but the problem is I don't want my program to be launched again the next time the user click the Home button. I know that this can be done by going in the parameters / Applications / my app / erase default actions but I would like to do it from my program so that the user doesn't have to search this function. How can it be done ?
