[android help] Hide warnings in layout files

	I updated Eclipse and SDK and now in every xml file the TextViews have the warning "Consider making the text value selectable by specifying android:textIsSelectable="true"". Is it possible to hide the warnings, I hate to have my project with a lot of yellow exclamation marks. asked Mar 4 at 15:55

	Go to the propeties of your project. Go to Android Lint Preferences. Search for SelectableText and change the severity to ignore. You can also do this in Eclipse preferences for all projects. answered Mar 4 at 15:58

	There is a good reason for this warning. By just disabling it, you are basically ignoring user interface guidelines of Android and you are not using the full potential of the user interface of your app. Therefore looking at each text view and explicitly setting this attribute to either false or true will increase the quality of your app. answered Mar 28 at 17:30

The selected answer is the correct one... However should you decide to go with Lint be aware that not every android target supports this tag. I discovered this the hard way when I followed it's advice and received "No resource identifier found for attribute 'textIsSelectable' in package 'android'" as an error when it tried to compile the layout XML values. Note I was targeting Android 2.2 answered 6 mins ago

[android help] Bizarre exceptions being thrown in android activity

So, I have an android app to finish making for a project, the same one as I asked questions about here before but this time I'm having trouble with a completely different aspect. Since the app is about Pokémon, in one activity I have some TextViews, EditTexts and a button set up to make an IV calculator. If you're curious and don't know what "IVs" are in Pokémon, google it of course. Anyway, getting back on track...this image here I put together highlights my problem (http://oi45.tinypic.com/faodvk.jpg)

Above the boxed line you see there is a ClassCastException thrown saying cannot cast from type TextView to EditText...I know what that means in a general sense but I cannot fathom why it is occurring here because as you can see in the relevant line of code (which i pasted into the image) the part of that line that involves casting is casting from View (return type of findViewById) to EditText. The arg R.id.EditText06 IS referring to an EditText in my activity so I don't see where the bad casting attempt is supposedly occurring. Just for a little clarification of the context of this, this is part of stuff coded into the OnClickListener of the button.

Apologies if this question seems perhaps incomplete as regards content shown about the problem but it is quite late for me (so much so that I'm going to bed upon posting this) and please do ask for me to post other stuff if you feel you need it to try to help me.

[android help] Extend AsyncTask with radioGroup

	How can I use RadioGroup in class that extends AsyncTask ? I also tried to use AsyncTask as inner class but didnt work. It gives constructor RadioGroup(..) undefined error ! final RadioGroup rg = new RadioGroup(this); asked 27 mins ago

	that's impossible because RadioGroup is Android SDK class, even if you can, how do you start the AsyncTask? Does you want invoke an event when the RadioButton on? What's your meaning? answered 1 min ago

[android help] Android tutorials for OpenGL with API level 10

I am currently trying to learn how to use OpenGLes in Android, but all of the tutorials I have found do not use API level 10. (i.e. Gingerbread/2.3)

EDIT: Well, at least they say they use it, but when I build it gives me errors as if it isn't there...

They require EGLConfig in setting the renderer and surface. Example:

public void onSurfaceCreated(GL10 gl, EGLConfig config)...

Taken from this tutorial.

Would anyone know a solution to this, or a reference to a tutorial that does this?

[android help] Set the side of an image when using android:drawable____ in a button

If you want to define the accuracy size of the drawable, You should use Java code instead of android:drawableLeft

  Drawable dw = getResources().getDrawable(R.drawable.ic);
  dw.setBounds(0, 0, 100, 100); // set the size of the drawable to 100*100

  button.setCompoundDrawables(dw, null, null, null);

because of

 android:drawableLeft // equals with  setCompoundDrawablesWithIntrinsicBounds

and

 android:drawablePadding // this used to control the padding between the text and drawable

[android help] How to send data from an Android application to a server?

I'm developping an online Chess game in Android. The first player uses the app and the second a webpage in html.

What i want to do is to send the text with the information of every move each player makes in his turns. All the processing and validation parts of the game will be done in the Android application. The second player just receives the text, parses it into html code and then send a very similar text to the application in order to receive the authorisation of the move.

I'm really trying to spend the least possible of internet resources.

I've been searching what's my best option in order to send the messages with Android, but since I'm not very experienced with it, I don't know what to do.

I found these possibilities for sending the messages:

• GCM


• Android ServerSockets and Sockets


• Making Push technology, like long-polling

I have never used any of those technologies, but I would like to know which one could be the best for starting to make a deeper research of.

As you can see a chess game doesn't need a great amount of messaging since I have to send and receive a single message per move and per the authorisation of it by the chess engine in the Android application.

If you know a better solution or links with an example of the technology I should use, I would be very grateful.

[android help] Android - Grabbing an image from a URL and displaying it in an ImageView with an AsyncTask

I'm trying to get the app to show an image from a URL, im fairly certain the issue is with the AsyncTask but I've returned to this code several times over the past week and I still cant see where I'm going wrong. The Internet permission is set and I am getting no LogCat ImageView eventImage2; eventImage2 = (ImageView) findViewById(R.id.eventImage2); new imageupdate().execute(); public class imageupdate extends AsyncTask { @Override protected Bitmap doInBackground(Bitmap... url) { URL url1; try { url1 = new URL("http://masterzangetsu.eu/Apps/NowIGetYou/banner.png"); HttpURLConnection connection = (HttpURLConnection) url1.openConnection(); Bitmap result = null; InputStream is = connection.getInputStream(); Bitmap img = BitmapFactory.decodeStream(is); img = result; } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return img; } protected void onPreExecute(String result) { } protected void onPostExecute(Bitmap result) { super.onPostExecute(result); eventImage2.setImageBitmap(result); } } asked 13 mins ago

Change this Bitmap result = null; InputStream is = connection.getInputStream(); Bitmap img = BitmapFactory.decodeStream(is); img = result; to Bitmap img = null; InputStream is = connection.getInputStream(); Bitmap img = BitmapFactory.decodeStream(is); result = img; and return result in doInBackground(). You have them switched around so 'img' will be null no matter what happens. Also, you can't use Toast in doInBackground() as this method isn't run on the UI thread. You will need to make that a Log or put your Toast in onPostExecute() or onProgressUpdate(). These are the things I see. If you are still having problems then you need to be a little more clear on what specifically. You will need to debug and use breakpoints to see what isn't being returned that should be and pinpoint a little more what the problem is answered 4 mins ago

[android help] initLoader() and onCreateOptionsMenu() threading issue

I am fetching some data from SQLite in a Fragment using a CursorLoader. The initLoader() for this is executed in onActivityCreated()...

public class MyFragment extends Fragment implements LoaderCallbacks
{
    MenuItem menuItemOne;

    @Override
    public void onActivityCreated(Bundle savedInstanceState)
    {
        super.onActivityCreated(savedInstanceState);
        getLoaderManager().initLoader(0, null, this);
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
    {
        inflater.inflate(R.menu.myMenu, menu);
        menuItemOne = menu.findItem(R.id.menuItemOne);
    }

    @Override
    public void onLoadFinished(Loader loader, Cursor cursor)
    {
        menuItemOne.doSomething();
    }
}

The above code is simplified for ease of reading. Here is my problem...

• On a Nexus S, there is no problem.


• On a Nexus 7, a null pointer arises in onLoadFinished. menuItemOne is null here.

The Nexus S is using Android 4.1.2 and the Nexus 7 is using Android 4.2.2.

• Should I be running initLoader() elsewhere?


• Do you think there is a bug/difference in the Android versions?

[android help] How to disable button in another activity?

I have a game activity and when it ends it goes to main menu and now I need to disable the button which starts the game that just ended. Let's call my game class classGame and my menu classMenu. I tried:

in my classGame:

classMenu obj = new classMenu();

And then in the same class when the time is right I call:

obj.myButtonToBeDisabled.setEnabled(false);

But I get stactOverflow errors on line where I created my obj as soon my menu activity starts. How to do this?

EDIT: I've also tried this in my gameClass:

public void disableButton(){
        button.setEnabled(false);
    }

and then calling it:

obj.disableButton

But the same error.

[android help] how to return to previous fragment activity

	Three fragment activities: MainFragmentActivity, Reports and ReportsType. Reports is calling ReportsType. There is a back button in ReportsType to go back with the following code: public void goBackReport(View v) { finish(); // why MainFragmentActivity.java is called after finish()? } But its always returning to MainFragmentActivity.java. But it should be Reports.java. asked 11 mins ago

	Try this.. Intent i=new Intent(this,MainFragmentActivity.class) startActivity(i); finish(); Intent i=new Intent(this,Reports.class) startActivity(i); finish(); Intent i=new Intent(this,ReportsType.class) startActivity(i); finish(); When you call new Activity write finish() in last answered 7 mins ago

	There's no concept of calling finish() on Fragment. Instead, you should keep stack of fragments when performing transactions. For example: ft.addToBackStack(null); // ft is FragmentTransaction So, when you press back-key, the current activity (which holds multiple fragments) will load previous fragment rather than finishing itself. answered 1 min ago

[android help] Why doesn't Android Facebook interface work with Fragments?

As far as I could determine, the Facebook auth API does not support Fragments. Specifically, the onComplete() callback from the Facebook authorize() call works with Activities, but not with Fragments.

So I put together a simple workaround for Fragments. The solution depends on the fact that onActivityResult() is also called in the parent Activity when the authorize() call completes, so you can use it to set up a separate callback mechanism for the Fragment.

First, set up a variable in the parent Activity to carry the target Fragment's name, say

TargetFragment mTargetFragment;

You can initialize it when the Fragment is first instantiated like this:

@Override
public void onAttachFragment(Fragment fragment) {
    super.onAttachFragment(fragment);

    String fragmentSimpleName = fragment.getClass().getSimpleName();

    if (fragmentSimpleName.equals("TargetFragment"))
        mTargetFragment = (TargetFragment)fragment;        
}

Then add a couple of lines to the onActivityResult() function:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (mTargetFragment != null)       
        mTargetFragment.myCallBack(requestCode, resultCode, data);
}

Now you can just mimic the code you would ordinarily put in the onComplete() callback in the new myCallBack() function:

public void myCallBack(int requestCode, int resultCode, Intent data) {
    mFacebook.authorizeCallback(requestCode, resultCode, data);

    // other code from your onComplete() function ...
}

I hope this can help someone else. Cheers!
