  • How to have a run in an Service?

    - by user1497664
    I have implemented an service that runs in a seperate process. This service contains a separate thread where i have a socket connection. This thread has a run() where it is continuously sending data to the port. My problem is after triggering the run() in the thread i don't get any contact with it anymore, i can see in the program that have open the socket that it consciously sends the data but the idea was that i while it is running i could change data that it sends for an example time. here is my run in the external thread: public void run() { if(run) { // Team and player names message is sent when entering in a game setBaseMessage(); SendMessageToCOMPort(base_message + CalculateCRC(base_message)); sleep(); // waits for 100 ms } } Anyone have any idea what might be wrong ?

  • How put <Spanned> into list.setAdapter?

    - by svebee
    Simple but little tricky, if I have list.setAdapter(new ArrayAdapter<String>(this,R.layout.double_row, R.id.doubleRow, articleItemsHelper)); it works if articleItemsHelper is String, but I wanna have HTML formatting in there so when articleItemsHelper is type Spanned this (adapter) doesn't work. ArrayList<Spanned> articleItemsHelper = new ArrayList<Spanned>(); What's the solution?

  • Which is the 'correct' way to do this (if statement)

    - by frinkz
    I've got plenty of these lying around, and I'm wondering if I'm going to face any trouble - or performance problems. I have method A: MyClass monkey; ... if(monkey != null) { ... } Or method B: boolean hasMonkey; //This is set to TRUE when monkey is not null MyClass monkey; ... if(hasMonkey) { ... } On a functional level, they both do the same thing. Right now, I'm using method A. Is that a bad way of doing things? Which is going to perform better?

  • How to save coordinates with Google Map?

    - by Pavel
    Hey everyone. I'm currently developing an app which uses tabs and google map. What I want to do is to get the gps positions, say 3, and store them in sql db (which I'm already doing) and then display them on the map. I already created canvas, added to overlay but those points disappear when I'm changing tabs so I thought if there is a way to somehow store those coords with google map so I can retrieve them and display them nicely whenever I'm clicking the "map tab"? Please can anyone help?

  • Creating Linear Layout with TextViews using a for loop

    - by cad8
    Hi all, I was wondering if there is a way to dynamically create an additional linear layout with a textview within a predefined liner layout. THis is my code so you get the gist of what I am asking: LinearLayout MainLL= (LinearLayout) findViewById(R.id.myLayoutId); for(int i=0; i<5; i++) { LinearLayout childLL= new LinearLayout(this); childLL.setOrientation(LinearLayout.VERTICAL); childLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); childLL.setGravity(Gravity.LEFT); TextView text = new TextView(this); text.setText("The Value of i is :"i); text.setTextSize(12); text.setGravity(Gravity.LEFT); text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); childLL.addView(text); MainLL.addView(childLL); } My problem is that I am only getting "The Value of i is :0" as the output, i.e. the first instance. Any help would be much appreciated

  • Only first word of two strings gets added to db

    - by dkgeld
    When trying to add words to a database via php, only the first word of both strings gets added. I send the text via this code: public void sendTextToDB() { valcom = editText1.getText().toString(); valnm = editText2.getText().toString(); t = new Thread() { public void run() { try { url = new URL("http://10.0.2.2/HB/hikebuddy.php?function=setcomm&comment="+valcom+"&name="+valnm); h = (HttpURLConnection)url.openConnection(); if( h.getResponseCode() == HttpURLConnection.HTTP_OK){ is = h.getInputStream(); }else{ is = h.getErrorStream(); } h.disconnect(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); Log.d("Test", "CONNECTION FAILED 1"); } } }; t.start(); } When tested with spaces and commas etc. in a browser, the php function adds all text. The strings also return the full value when inserted into a dialog. How do I fix this? Thank you.

  • How do I get the raw dimensions of a bitmap in an ImageView?

    - by potatoe
    It seems like I might be overlooking something obvious, but I can't figure out how to retrieve the raw (unscaled) dimensions of a bitmap being displayed in an ImageView. For example, if I load a bitmap using Bitmap b = BitmapFactory.decodeResource(...), I can get those dimensions from b.getWidth() and b.getHeight(), and I could pass the bitmap into an ImageView using setImageBitmap(b). But if I have a subclass of ImageView, is there any way to retrieve those dimensions without having to pass them in explicitly? I guess I'm looking for a getImageBitmap() analog of ImageView's setImageBitmap() method, which would retrieve a Bitmap object that I can call getWidth() and getHeight() on. Any other way to retrieve the original dimensions would work too, though.

  • Customizing Sipdroid

    - by Seshu Vinay
    I have a Voip based app. So i thought of customizing SipDroid open source project. As the starting phase i have changed all the package names, Class names etc. It perfectly works on my Samsung Galaxy Y. But i tried with many other mobiles, Voice is not audible. Call is being initialized but could not hear voice. In Samsung galaxy young, voice is clearly audible for both incoming and outgoing calls. But in all the other phones i have tested i can hear only beep sounds. What could be the problem? I tried calling the other mobile(that has Sip Droid) with my Samsung Galaxy Young(customized app) I could hear voice in my app but could not hear in Sipdroid. But when i tried calling Sipdroid to Sipdroid, it works fine in all the mobiles.

My application will still debug etc. I just get nothing useful in my Console. Any ideas how to fix this? It appears intermittent. It starts doing it after a few minutes, continues to do it for quite a while and occasionally goes away again. This has happened on my last laptop and now on my new laptop with a completely fresh install etc.

  • Proper way to 100% wakes my device?

    - by quiel
    Do you have better way to make the device awakes by 100%? I repeatedly call the acquire() but I'm not sure if that is correct. Or should I just call the acquire() once? Or should I make use of Intent.ACTION_SCREEN_OFF? public class MyServiceThatKeepsTheDeviceAwake extends IntentService { ... @Override public void onCreate() { super.onCreate(); mPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE); mWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE, TAG); } @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); mWakeLock.acquire(); } // No release

  • Language resources in separate APK?

    - by Rudolf
    I'm wondering if it is possible to create a separate APK file which contains only language specific strings and somehow persuade my program to try to read the string resources first from that package's resource and then from the program's own resources... I would like to have a main program with 2-3 mayor laguages and the rest of the languages would go into a separate language pack. (This is to keep the main program size small as I have already 12 translations)

  • BitmapFactory.decodeFile out of memory with images 2400x2400

    - by alasarr
    I need to send an image from a file to a server. The server request the image in a resolution of 2400x2400. What I'm trying to do is: 1) Get a Bitmap using BitmapFactory.decodeFile using the correct inSampleSize. 2) Compress the image in JPEG with a quality of 40% 3) Encode the image in base64 4) Sent to the server I cannot achieve the first step, it throws an out of memory exception. I'm sure the inSampleSize is correct but I suppose even with inSampleSize the Bitmap is huge (around 30 MB in DDMS). Any ideas how can do it? Can I do these steps without created a bitmap object? I mean doing it on filesystem instead of RAM memory. This is the current code: // The following function calculate the correct inSampleSize Bitmap image = Util.decodeSampledBitmapFromFile(imagePath, width,height); // compressing the image ByteArrayOutputStream baos = new ByteArrayOutputStream(); image.compress(Bitmap.CompressFormat.JPEG, 40, baos); // encode image String encodedImage = Base64.encodeToString(baos.toByteArray(),Base64.DEFAULT));
