[android help] How to replace new line characters with actual new lines in a string in android?

Tell me more ×

	I need to display a string which contains a lot of new line '\n'.These needs to be replaced with actual newlines in that string. How can I do that in android? asked 51 mins ago

	you should concatenate the newline operator like: String str = "This is testing" + "\n" + "How are you?"; you said from database you could split like: String[] separated = str.split("\n"); separated[0]; // this will contain "This is testing" separated[1]; // this will contain "How are you?" and then concatenate them answered 26 mins ago

What seems to be happening is the string you receive from your database contains not the new line character, but rather the characters \ and n. The simplest fix is use simply the String.replace function to replace the character sequence \ n by the character \n like so: String str = getStringWithFakeNewlines(); str.replace("\\n", "\n"); // The first backslash is doubled to find actual backslashes answered 4 mins ago

[android help] Execute a thread of an activity based on item position clicked in ListView

Okay, here is the the problem I am having. I am developing a simple messaging client similar to the OEM one found on Android devices.

I currently have a ConversationList.java containing a ListView with the usernames of people the actual user is engaged in conversation with.

I want to launch specific threads of a ConversationThread.java (which is an activity that contains another ListView holding the messages exchanged between users).

I thought originally about instantiating a new ConversationThread upon each addition of a conversation in ConversationList.java, then adding that to an array list. Then based on the position parameter on the onItemClick on the ListView referenced to the position of the ArrayList of ConversationThread execute that particular "thread" of ConversationThread.

public class ConversationList extends Activity 
{
ArrayList ListOfActiveThreads = new ArrayList();
ListView convoList;
ArrayAdapter adapter;
ArrayList ActiveConversations = new ArrayList();

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_conversation_list);
    convoList = (ListView) findViewById( R.id.Conversations );
    Button addConvo = (Button) findViewById(R.id.Talk);
    adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, ActiveConversations);
    convoList.setAdapter(adapter);

    addConvo.setOnClickListener(new OnClickListener()  
    {
        public void onClick(View v) //will add the person to be sending to to the list of active conversations
        {
            EditText person2add = (EditText) findViewById(R.id.Friend2Sendto);
            String person = person2add.getText().toString();
ConversationThread newMessage = new ComversationThread(person);
ListOfActiveThreads.add(newMessage);
            adapter.add(person);
            adapter.notifyDataSetChanged();
            person2add.setText("");         

        }
    });

    convoList.setOnItemClickListener(new ListView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView a, View v, int i, long l) 
        {

        Intent mainIntent = new Intent(ConversationList.this, ConversationThread.class); //this starts a new instance of the ConversationThread class each time
        startActivity(mainIntent);
/* Here I want to start or resume the ConversationThread.getposition(i) */
        }
    });

}

My question is, for the ConversationList.java I have a basic android activity template, with an oncreate() class etc. Do I make this class implement Runnable and somehow make it act like a Thread in Java? or is there a better way of creating a list of running activities to be utilized by the ListView.

[General] Delete contact from phone but NOT Gmail contacts

You could go to Settings/Accounts-Google/, tap your Google account, then uncheck Contacts. This will unsync your Contacts, so if you delete a contact on your phone, it won't delete from your main Google account. HOWEVER, if you check the Contacts box again, it will sync and then you will delete the contact from your Google account. So it's kind of a one-time deal.

Another option would be to import all of your Google Contacts into your Phone account, not your Google account, using the Import function in the People app. Then you could unsync Google Contacts to remove all of the contacts that sync with your Google Account. You would then have all of your Google Contacts in your Phone account, which does NOT sync with your Google account, and so if you delete an contact on your phone, it won't delete in your Google Account.

Sorry, that sounded pretty confusing, didn't it?

[General] 3 problems with a kyocera hydro phone

1 When I go to system settings > sound > phone ringtone (right now it is set to unknown ringtone) the "unknown ringtone" sounds like the gong from "the gong show" (for you young people the gong in question is an old Chinese gong). When I try to change the phones default ringtone. It will take and last maybe a few days to maybe a week then revert back to the Chinese gong ringtone (with the name unknown ringtone). The phone is rooted and I have checked every sound file and ringtone I could find (I only looked in the logical places were the ringtones would be stored). I even found the sound files for things like the keyboard click, the camera shutter click and so on. I played every sound file that I could find and no gong. That gong ringtone has to be in the phone somewere. I am a tech though I am better at Windows based stuff then Android/Linux Os, But I am learning. It took me about 2 months of reading everything I could find online about rooting before I even tried to root the phone. I also fix 2 way radios, a little background on me. I have never had a cell phone change ringtones on it's own like this and I am stumped.

2. This started a few days ago. The icon for the voice mail is up in the pull down menu on the very top of the phone even though there is no voice mail messages. I can't get the icon to go away. I have already tried pulling the battery for a few hours and no change.

3. This started last night. I have no internet available on the phone unless I turn on the wifi and tie into my wireless router. The voice and sms still work fine.

Anyone have any ideas short of chucking the phone and getting a new one?

[General] Samsung Note II VZW - No data from WiFi or cell signal

As the title says, I'm getting no data from my home WiFi or 4G from the cell signal, despite them being shown as connected.
I noticed it just a few minutes ago. I was looking into Voodoo RootKeeper because I haven't updated to the latest OTA update and I've been wanting to soon, it was mentioned that SuperUser should be fully updated for it to work. While looking through SU settings, I noticed the option to set SU as a system app, so I did it. It rebooted and just before finishing the boot it had a message saying something about configuring apps (similar to what you would see after an update, I believe). Once it finished I was going to update some apps that needed updating and Play said it had no connection, checked Chrome and it was the same story. So here I am.

My Note II is on Verizon, it is rooted, also has an unlocked bootloader (which is why I've waited so long to do the OTA). I haven't updated since I got it at the beginning of December last year, so the current version I'm running is 4.1.1

Any help is really extremely appreciated; my smartphone becomes a dumb phone without any networking, dumb phones make me sad

[android help] Test data sources in Android unit testing

I want to test parsing of data returned from server.

I thought I might create several test XML files and then feed them to the sax parser which uses my custom data handler (as in the application that I test).

But where should I put those test XMLs?

I tried with [project_root]/res/xml, but then I get the error:

android.content.res.Resources$NotFoundException: Resource ID #0x7f040000 type #0x1c is not valid at android.content.res.Resources.loadXmlResourceParser(Resources.java:1870) at android.content.res.Resources.getXml(Resources.java:779)

Does that mean that the xml is invalid, or that android couldn't find the XML file? (I use the same XML that comes from the server - copied it from the firebug's net panel and pasted into the file).

Can I somehow read that XML as a text file, since getContext().getResources().getXml(R.xml.test_response1) returns XmlResourceParser instead of String (which I'd prefer)?

[General] Suddenly unable to connect my N7 to my phone with bluetooth

Tried that. Still didn't work. Also tested with my blue tooth headphones, those connected up just fine. Also unpaired and tried from step 1, and still no go.

Also, if it helps. I noticed that they actually don't even bother connecting to each other. Say for example, my headphones. I tap on the headphone's name on the list and it goes "connecting..." Even if the headphones are off. When I try to get my S3 and N7 to connect, they don't even get to that point.

[android help] possible to change text size/color for ActionBar?

Is there possible way to change size/color of ActionBar's title and subtitle?

I am using ActionBarSherlock for bridging between lower and higher versions. ActionBarSherlock provides way to customize text style in SherlockActionBarCompat, but there seems no way to make it in SherlockActionBarNative.

edit: added by Jake and removed by author

edit: Close to the solution:

Thank Jake, the author of ABS, for the help.

Now it's almost done, except that the actionBarSize can only be estimated for an approximate absolute dimension(60dp for my app) from quite a few trials; wrap_content causes API2.2 to expand the whole screen and does API4.2.2 exception thrown while parsing xml.

Addition:
when actionBarSize set as 0dp, the output is as (http://i.stack.imgur.com/xX4E1.png , low reputation to post images): API2.2 in the left, the action bar occupies the whole screen without title, API4.2.2 in the right, content does without action bar.

when set as wrap_content, same output for API2.2, and exception thrown as: Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x10

Hi I'm working on an Android App which has the possibility of connecting to a server. This application can work online or offline. For connection to the server, I use AsyncTask, which and in doInBackground is where I do all the network operations. Then I create a new instance of the Asynctask when I click a button.

I have used sql select query in android app which works fine on newer versions of android i.e it takes 30 to 40 seconds on Samsung galaxy tab( android 4.0.3) to retreive data from sqlite database, but on device with older version of android 2.3 it takes 18 minutes to retreive data. If i remove "order by x_unitperson.UNITSEQ" then its performance do not decreases on android 2.3. How can i increase its performance on android 2.3 without removing order by clause.

[android help] Converting YUV->RGB(Image processing)->YUV during onPreviewFrame in android?

I am capturing image using SurfaceView and getting Yuv Raw preview data in public void onPreviewFrame4(byte[] data, Camera camera)

I have to perform some image preprocessing in onPreviewFrame so i need to convert Yuv preview data to RGB data than image preprocessing and back to Yuv data.

I have used both function for encoding and decoding Yuv data to RGB as following :

public void onPreviewFrame(byte[] data, Camera camera) {
    Point cameraResolution = configManager.getCameraResolution();
    if (data != null) {
        Log.i("DEBUG", "data Not Null");

                // Preprocessing
                Log.i("DEBUG", "Try For Image Processing");
                Camera.Parameters mParameters = camera.getParameters();
                Size mSize = mParameters.getPreviewSize();
                int mWidth = mSize.width;
                int mHeight = mSize.height;
                int[] mIntArray = new int[mWidth * mHeight];

                // Decode Yuv data to integer array

                // than image preprocessing 
                // and back to mIntArray.

                // Encode intArray to Yuv data
                encodeYUV420SP(data, mIntArray, mWidth, mHeight);
                    }
}

            V[index++] = v;
        }
    }

The problem is that encoding and decoding Yuv data might have some mistake because if i skip the preprocessing step than also encoded Yuv data are differ from original data of PreviewCallback.

Please help me to resolve this issue. I have to used this code in OCR scanning so i need to implement this type of logic.

If any other way of doing same thing than please provide me.

Thanks in advance. :)

[android help] Memory overflow when loading large textures

I have a GLSurfaceView and a Renderer which loads textures in onSurfaceCreated. My textures are created like so :

public Texture3D(final GL10 gl, final int id) {
    _pBitmap = BitmapFactory.decodeResource(Utils.getResources(), id);
    gl.glEnable(GL10.GL_TEXTURE_2D);

    gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST);
    texture = newTextureID(gl);
    gl.glBindTexture(GL10.GL_TEXTURE_2D, texture);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);

    gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);


    GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, _pBitmap, 0);

    _pBitmap.recycle();     
    _pBitmap = null;

    gl.glEnable(GL10.GL_BLEND);
}

I store them in an HashMap :

textures.put(R.drawable.tile, new Texture3D(gl, R.drawable.tile));

My problem is when I create a texture from a large image (720x1280, 561 Ko) after I sometimes get the following error :

That points to the first line of the constructor where I use BitmapFactory.decodeResource. On my Galaxy S3 I get the error when I switch to another fragment and then I come back to the fragment that displays the GLSurfaceView (onPause and onResume are called on the GLSurfaceView).

How can I avoid this problem ? I tried this solution but I lose too much quality and in rare case the bug happens anyway (probably on old phones models).

Is there something wrong how I create / store my textures ? Also do you know why I don't always get this error ? (generally I get it the second time I load the textures).

Thanks asked 2 days ago
This question has an open bounty worth +50 reputation from Venkat ending in 6 days. Looking for an answer drawing from credible and/or official sources. i am stuck with this. please anybody help. i want to test the amazon app in my app.

I'm going to try to explain how can you have the demo working, because, I think, that's your question, sorry if I'm wrong... Install the AmazonSDKTester.apk in your device and open it. It's inside tools folder in the SDK package. For install it you can use in terminal: adb install AmazonSDKTester.apk Next add your project to Eclipse: File > New > Project...>Android Project from Existing Code , browse the Button Clicker Demo Project in the SDK folder and Finish. Copy the amazon.sdktester.json file to SD memory. In the ButtonClicker project folder, go to assets folder and add the amazon.sdktester.json file to the SD memory. An easy way it's dragging the file to the SD folder using DDMS file explorer. Your SD folder may be different depends on device, in my Nexus S is like you can see in the image. And that's it, you must have Button Clicker Demo sample fully working. When you make a purchase you can go to the AmazonSDKTester and see all your purchases. Hope it helps you and solves your problem. answered 4 mins ago

[android help] My Runner using a Handler is not working on android

Here's what I got so far guys, this is my app, all it does is display a digital clock and move the clock to a new part of the screen every 30 seconds, but it doesn't actually do that last part, here's the code:

public class MainActivity extends Activity {

private Runnable runnable = new Runnable(){
    @Override
    public void run() {         
        handler.sendEmptyMessage(0);
    }
};
Handler handler = new Handler() {       
    @Override
    public void handleMessage(Message msg) {            
        //change the text position here         
        this.postDelayed(runnable , 30000);
        }
    }; 

@Override
protected void onCreate(Bundle savedInstanceState) {


    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    TextView textView = (TextView) findViewById(R.id.digitalClock);  
    Random r = new Random();

    Thread thread =new Thread(runnable );
    thread.start();

    int x = r.nextInt(350 - 100);
    int y = r.nextInt(800 - 100);

    textView.setX(x);  
    textView.setY(y);
    }

I just cant seem to get this to work, been scanning the internet for about a week now. I think it's got something to do with the "New Thread" but not too sure what.
