  • android.widget.ShareActionProvider does not work on the emulator

    Reported by Lars.Vo...@gmail.comFeb 13, 2012
    If I add a ShareActionProvider to my application it works file on a real device but not on the emulator. If I press the Share button in the emulator nothing happens.
    
    
    Here is my menu:
    
    <?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android" >
    
       <item android:id="@+id/menu_share"
              android:title="Share"
              android:showAsAction="ifRoom"
              android:actionProviderClass="android.widget.ShareActionProvider" />
        <item
            android:id="@+id/item1"
            android:showAsAction="ifRoom"
            android:title="Hello">
        </item>
        <item
            android:id="@+id/item2"
            android:showAsAction="ifRoom"
            android:title="This will not fit in the Action bar">
        </item>
    
    </menu>
    
    I add this menu to my Activity:
    
    @Override
    	public boolean onCreateOptionsMenu(Menu menu) {
    		getMenuInflater().inflate(R.menu.mymenu, menu);
    		provider = (ShareActionProvider) menu.findItem(R.id.menu_share)
    				.getActionProvider();
    		doShare();
    		return true;
    	}
    
    
    
    	public void doShare() {
    		Intent intent = new Intent(Intent.ACTION_SEND);
    		intent.setType("text/plain");
    		intent.putExtra(Intent.EXTRA_TEXT, "Message");
    		provider.setShareIntent(intent);
    	}

    This is due to their only being a single (or zero) applications which support that intent. If this is the case the provider will not allow any interaction. It would be nice if there was a Toast or the dropdown still showed with a message of some sort.

    I agree with Jake : this is because the emulator do not have many apps that can answer the intent.

    SMS app is available and this accepts Intent.ACTION_SEND. If I trigger this directly it also works. Hence I suspect still a bug.

    If you add another app (see attachment for example) to your emulator supporting ShareIntents of type text/plain and accepting Intent.ACTION_SEND, the ShareProvider will work. It then also displays the already mentioned Messaging App. This however should be considered a workaround.

    I can reproduce this bug too, and the weird thing is it works if you've opened the list at least once, with at least two intents. 
    
    For example:
    
    Two activities: Open list.
    Change intent to one that resolves to one activity.
    Open list: Still works.
    
    It doesn't work if you haven't yet opened it.

    Seems related to these lines in ActivityChooserView$ActivityChooserViewAdapter:
    
    if (!mShowDefaultActivity && mDataModel.getDefaultActivity() != null) {
    activityCount--;
    }
    
    IF you haven't opened the list yet, activityCount gets subtracted by 1, getCount() returns 0 and the button gets disabled. The list still contains one activity.
    
    The title should be changed, because this doesn't really have anything to do with the emulator and affects real production devices. Even if there's only 1 activity, it should still be shown instead of disabling the button.
