You will need to extend `FragmentActivity` instead of the normal `Activity`. Then you will be able to call `getSupportFragmentManager()` which works the same way as `getFragmentManager()`.

You have only to change your Android Target to API Level = 12

For people trying to make this work with Google Maps SDK see https://stackoverflow.com/questions/17042459/getfragmentmanager-with-api8 and remember to update your layout file too!

I was wondering how to limit the amount of LINES (not characters as asked in other questions) a user can enter when editing a UITextField.

Ideally, I would like to limit the input to max. 10 lines.

Where would I need to start? Do I do this with a method? In

     - (BOOL)textViewShouldBeginEditing:(UITextView *)aTextView

I&#39;m pretty happy with s3cmd, but there is one issue: How to copy all files from one S3 bucket to another? Is it even possible?

EDIT: I&#39;ve found a way to copy files between buckets using Python with boto:

    from boto.s3.connection import S3Connection

    def copyBucket(srcBucketName, dstBucketName, maxKeys = 100):
      conn = S3Connection(awsAccessKey, awsSecretKey)
    
      srcBucket = conn.get_bucket(srcBucketName);
      dstBucket = conn.get_bucket(dstBucketName);
    
      resultMarker = &#39;&#39;
      while True:
        keys = srcBucket.get_all_keys(max_keys = maxKeys, marker = resultMarker)
    
        for k in keys:
          print &#39;Copying &#39; + k.key + &#39; from &#39; + srcBucketName + &#39; to &#39; + dstBucketName
    
          t0 = time.clock()
          dstBucket.copy_key(k.key, srcBucketName, k.key)
          print time.clock() - t0, &#39; seconds&#39;
    
        if len(keys) &lt; maxKeys:
          print &#39;Done&#39;
          break
        
        resultMarker = keys[maxKeys - 1].key

Syncing is almost as straight forward as copying. There are fields for ETag, size, and last-modified available for keys.

Maybe this helps others as well.

Is it possible to copy all files from one S3 bucket to another with s3cmd?

I started trying to add fragments to my Android app, which is based on 2.1, using the Android Compatibility Package that just came out on March 3rd.  I included the library into my project, and started moving the code from my Activity-based class to a Fragment-based one, but I noticed that the Fragment examples from Google seem to rely on the fact that the Activity class in 3.0 (Honeycomb) has the new method getFragmentManager().  It seems to be an integral hook into the Fragment system.

I&#39;ve tried to look inside the Compatibility Package library for some included Activity implementation that has getFragmentManager(), but I can&#39;t find it.  Does anyone know where I can find getFragmentManager() so I can include Fragments for Honeycomb compatibility, or if not do you know how I can include Fragments without using a FragmentManager?

I am coding an app using jQuery, jqTouch and phonegap and have run across a persistent problem which arises when a user submits a form using the Go button on the soft keyboard.

Although it is easy to get the cursor to move to the appropriate form input element by using `$(&#39;#input_element_id&#39;).focus()`, the orange outline highlight always returns to the last input element on the form. (The highlight does not show up when the form is submitted using the form submit button.)

What I need is to find a way either to disable the orange highlight completely or else make it move to the same input element as the cursor.

So far, I have tried adding the following to my CSS:

    .class_id:focus {
    	outline: none;
    }

This works in Chrome but not on the emulator or on my phone. I have also tried editing the jqTouch `theme.css` to read:

    ul li input[type=&quot;text&quot;] {
    	-webkit-tap-highlight-color: rgba(0, 0, 0, 0); and
    	-webkit-focus-ring-color:  rgba(0, 0, 0, 0);
    }

With no effect.
I have also tried each of the following additions to the `AndroidManifest.xml` file:
	
    android:imeOptions=&quot;actionNone&quot;
    android:imeOptions=&quot;actionSend|flagNoEnterAction&quot;
    android:imeOptions=&quot;actionGo|flagNoEnterAction&quot;

None of which have any effect.

Update: I have done some more troubleshooting with this and to date have found:

1. The outline property works only on Chrome, not on the Android browser.

2. The `-webkit-tap-highlight-color` property does in fact work on the Android browser, though not on Chrome. It disables the highlight on focus as well as on tapping.

3. The `-webkit-focus-ring-color` property does not seem to work on either browser.

Pinch zoom for custom view

I want to show all my validation error&#39;s of `EdiText` fields in a popup as shown in below image:

![Error alert in popup][1]

As far as I know Android has drawables: 

&gt;  1) popup_inline_error.9.png 

![popup_inline_error.9.png][2]


&gt; 2) popup_inline_error_above.9.png

![popup_inline_error_above.9][3]
&gt; 3) indicator_input_error.png

![indicator_input_error.png][4]

I am able to display the red error indicator inside the right side of the `EditText` by using:

    Drawable err_indiactor = getResources().getDrawable(R.drawable.indicator_input_error);
    mEdiText.setCompoundDrawablesWithIntrinsicBounds(null, null, err_indiactor, null);

Now also i want to display the error message as shown is the first image but it seems I am not getting any idea about this, though I think it should be a Custom Toast.

I&#39;m currently trying to adapt my application to use the &quot;Compatibility Libraries for Android v4&quot; to provide the benefits of the usage of fragments even to Android 1.6 users.

The implementation of a context menu seems to be tricky:

 - The main activity of the application
   is extending the **FragmentActivity**
   class.
 - The fragments are all based on one
   class which extends the Fragment class.
 - The fragment class is calling
   **registerForContextMenu()** in its **onCreateView()** method and overrides the methods
   **onCreateContextMenu()** and **onContextItemSelected()**.

For **onCreateContextMenu()** this works pretty well. The context menu is inflated from a resource file and slightly modified based on the selected item (which is based on a listView... even if the fragment is not an ListFragment).

The problem occurs when a context menu entry is selected.
**onContextItemSelected()** is called for all currently existing fragments starting with the first added one.

In my case the fragments are used to show the content of a folder structure. When the context menu of a subfolder fragment is opened and a menu item is selected, **onContextItemSelected()** is first called on the upper levels (depending on how many fragments are allowed/visible in this moment).

Right now, I use a workaround by a field on activity level which holds the tag of last fragment calling its **onCreateContextMenu()**. This way I can call &quot;return super.onContextItemSelected(item)&quot; in the begin of **onContextItemSelected()** when the stored tag is not the same as getTag().
But this approach looks a bit dirty to me.

Why is onContextItemSelected() called on all fragments? and not just one the one that was calling **onCreateContextMenu()**?

What is the most elegant way to handle this?



How to handle onContextItemSelected in a multi fragment activity?

I am having trouble using or understanding how popping 
FragmentTransactions off of the back stack handles the custom 
animations. Specifically, I expect it to call the &quot;out&quot; animation, but 
it doesn&#39;t seem to. 

I have a simple method to handle a fragment transaction 
(FragmentTransaction) where I add a fragment and apply a custom 
transition so that it will fade-in/fade-out. I am also adding this to 
the back stack so that the user can undo that transaction with the 
back button, essentially navigating to the state before the fragment 
was added. 

    protected void changeFragment() { 
        FragmentTransaction ft = fm.beginTransaction(); 
        ft.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out); 
        ft.add(R.id.fragment_container, new TestFragment()); 
        ft.addToBackStack(null); 
        ft.commit(); 
    } 

Everything works great moving forward, but when the user clicks the 
back button, the transition animations do not reverse. What I expected 
was that when the fragment got removed, it would use the fade out 
animation. Instead it seems to pop out (without animation) and then 
the container seems to fade in. I&#39;m not sure that this is exactly what 
is happening, but the fragment is definitely not fading out.  

My application uses the compatibility library to add fragment support, 
but I assume this to be applicable to Honeycomb (android-11) as well. 
Does anyone know if I am just doing something wrong here or if I am 
just expecting too much? Ideally, I would like to animate the 
fragments similarly to how Gmail (on the Xoom) does in regards to 
moving forward by clicking a message and then back by using the back 
button. Preferably not having to override the back button 
functionality and keep up with my own fragment state since I could 
have several &quot;transactions&quot; that I would want to back out of and I am 
not a fan of re-inventing wheels.

Animating fragments and the back stack

Am I missing something or do `Fragment`s not have a `onRestoreInstanceState()` method? If not, how do I go about attaining something similar?

android fragment onRestoreInstanceState

I have 2 fragments: (1)Frag1 (2)Frag2.

Frag1
=====

    bundl = new Bundle();
    bundl.putStringArrayList(&quot;elist&quot;, eList);
    
    Frag2 dv = new Frag2();
    dv.setArguments(bundl);
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.the_fragg,dv);
    ft.show(getFragmentManager().findFragmentById(R.id.the_fragg)); 
    ft.addToBackStack(null);
    ft.commit();

How do I get this data in Frag2?


How to use setArguments() and getArguments() methods in Fragments?

Is there a way in which we can implement `onBackPressed()` in Android Fragment similar to the way in which we implement in Android Activity?

As the Fragment lifecycle do not have `onBackPressed()`. Is there any other alternative method to over ride `onBackPressed()` in Android 3.0 fragments?

Is there any simple way of determining whether or not a certain activity is active?
I want to do certain things depending on which activity is active.

    else if (activityrunning == activity2)
    //do something else

Android: how do I check if activity is running?

I am doing a status bar notification in my android app that is triggered by c2dm. I don&#39;t want to display the notification if the app is running.  How do you determine if the app is running and is in the foreground?

How can I tell if Android app is running in the foreground?

I have implemented an activity that plays media from a URL in Android.

In order to add pause functionality when a call is incoming I created a receiver that sets a variable when the call is coming. The activity reads this variable in `onPause()`, pauses the music and resets it. When the call is done and the activity is resumed, the music is resumed in `onResume()`.

This works fine as long the activity has the focus. If I go back to home screen while the music is playing, and then the call comes, `onPause()` is not called. Hence, I can&#39;t stop and start the music.

Has anybody implemented a media player that intercepts incoming/outgoing calls and stops/starts music correctly?



Stopping &amp; starting music on incoming calls

In Android I have some activities, let&#39;s say A, B, C.

In A, I use this code to open B:

    Intent intent = new Intent(this, B.class);
    startActivity(intent);

In B, I use this code to open C:

    Intent intent = new Intent(this, C.class);
    startActivity(intent);

When the user taps a button in C, I want to go back to A and clear the back stack (close both B and C). So when the user use the back button B and C will not show up, I&#39;ve been trying the following:

    Intent intent = new Intent(this, A.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    startActivity(intent);

But B and C are still showing up if I use the back button when I&#39;m back in activity A. How can I avoid this?
