Android and iOs tips

Question

Do we have somewhere the reliable info about the minimum Android OS supported by Facebook SDK 3.0? I have checked on our side, it seems the Facebook SDK 3.0 does not work stable on Android FW 2.1 (some devices could not log-in, some device could log-in but crash after few minutes)

Thank you very much for your support. Hao

The Facebook SDK documentation reads:

In the 1st section titled: Install the Prerequisites

You'll need to have the Android 2.2 (API 8) components installed in order to use the Facebook SDK.

Source: https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/

I suspect it could indeed be the case that it only supports devices 2.2 and up. Logical step perhaps, considering that only 1.7% devices across the World use the 2.1 API.

Personally, and in all honesty, I support 2.2+ devices for supporting the Aviary SDK and never really checked if the Facebook SDK works on 2.1.

You should put your HorizontalListView inside a LinearLayout and pass the tag xlms to LinearLayout and the scroll will work perfectly!

You need to call startActivity() on the application's main thread. One way to do that is by doing the following:

Initialize a Handler and associate it with the application's main thread.
```
Handler handler = new Handler(Looper.getMainLooper());
```

Wrap the code that will start the Activity inside an anonymous Runnable class and pass it to the Handler#post(Runnable) method.


handler.post(new Runnable() {
    @Override
    public void run() {
        Intent intent = new Intent (MyActivity.this, NextActivity.class);
        startActivity(intent);
    }
});

you can use Something like this.


public class MyActivity extends Activity
{
    Handler hander = new Handler(){
        public void handleMessage(Message m){
            Intent intent = new Intent (MyActivity.this, Next.class);
            startActivity(intent);
        }
    };
    pubilc void onCreate(Bundle ic)
    {
       //your code setContentView() etc....
       Thread toRun = new Thread()
       {
              public void run()
              {
                    hander.sendMessage(1); 
              }
       }
       toRun.start();
    }
}

Well to start an activity of an class, a class should extends with activity according to me.

But if you want to start activity with some threading function you can do these things.

Instead of extends Thread, use implements Runnable. After that some class that have an Activity you just call the start thread and put your logic and that start Intent.

I think this is the good solution for you.
