Android Question SOLVED Use context in inline Java.

[tigrot]

Hi everybody,
I have the need to use context(in a activity) from inline Java code. I have looked around the way to solve this need.
Does anybody can help me?

Ciao

Ciao,
If you make a question and then you resolve it by yourself, I think it would be useful if you also post the solution.
This will help other users who might be having the same problem/question and it will probably show up in the search-engine of the forum.

You are right, forgive me!
in bold there is the answer to my silly question... This code deletes a SMS received from a single number(numero) with a body content (messaggio), but only in pre KitKat...
in code bold doesn't work: the code is processBA.context

Sub chiamajava
    Dim messaggio As String="Test"
    Dim numero As String="+3934XXXXXXX"
    native.RunMethod("deleteSMS",Array(messaggio, numero))
End Sub
#if JAVA
import android.net.Uri;
import android.database.Cursor;
import anywheresoftware.b4a.keywords.Common;
public void deleteSMS( String message, String number) {
            Common.Log("Messaggio:" + message);
            Common.Log("Numero:" + number);
            Uri uriSms = Uri.parse("content://sms");
         
            Cursor c = processBA.context.getContentResolver().query(uriSms, new String[] { "_id", "thread_id", "address", "person", "date", "body" }, null, null, null);


               if(c==null)
                {
                 return;
                }
                c.moveToFirst();
                do {
                    long id = c.getLong(0);
                    long threadId = c.getLong(1);
                    String address = c.getString(2);
                    String body = c.getString(5);
                    String date = c.getString(3);
        
                    Common.Log(address);
                    Common.Log(body);
                    if (message.equals(body) && address.equals(number)) {
                        Common.Log("Deleting SMS with id: " + threadId);
                        int rows = processBA.context.getContentResolver().delete(Uri.parse("content://sms/" + id), "date=?",new String[] { c.getString(4) });
                   }                     
                } while (c.moveToNext());
         
         }
#End If

Thank you and this is not a silly question. Many people are asking about javaobject and inline java
I am sure will be useful for someone.

Look also THIS

Thank you Marco. I'll give up... the App is published as Alpha. The mechanism is ok as is. An extra sms won't hurt! By the way, sms argument seems to like italian IT people!
