Inconsistent results on Android SQLite query

I'm experiencing some unexpected inconsistencies on the result of a SQL query on Android.

Given the following Schema (which is pretty simple):

public static final String TABLE_TOTD = "totd";
public static final String COLUMN_ID = "id";
public static final String COLUMN_TG = "tg";
public static final String COLUMN_EX = "ex";

private static final String DATABASE_NAME = "TOTD.db";

private static final String DATABASE_CREATE = "CREATE TABLE "
        + TABLE_TOTD + "("
            + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
            + COLUMN_TG + " TEXT NOT NULL, "
            + COLUMN_EX + " TEXT"
        + ");";

And the database being initialized and filled with a few sample texts:

    SQLiteDatabase db = mdbHelper.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(MySQLiteHelper.COLUMN_TG, "This is a text (1)");
    values.put(MySQLiteHelper.COLUMN_EX, "Example goes here");

    db.insert(MySQLiteHelper.TABLE_TOTD, null, values);
    [...]

I'm retrieving inconsistent results when querying with SQLiteDatabase.query() The following code does what it's expected to do, by returning a Cursor with the first row of the table.

    String[] projection = null;
    String selection = "id = 1";
    String[] selectionArgs = null;
    Cursor cursor = db.query(
            MySQLiteHelper.TABLE_TOTD,
            projection,
            selection,
            selectionArgs,
            null, null, null);

It works exactly the same by changing the selection and selectionArgs like this:

    String selection = "id = ?";
    String[] selectionArgs = {"1"};

But now, differently than expected, by performing the following changes, the returned Cursor will now be empty:

    String selection = "? = ?";
    String[] selectionArgs = {"id", "1"};

Actually, trying to push anything that is not the "1" into the arguments will cause the query to return an empty cursor.

I've tried the following:

    String selection = "? = 1";
    String[] selectionArgs = {"id"};

    String selection = "id ? 1";
    String[] selectionArgs = {"="};

    String selection = "?";
    String[] selectionArgs = {"id = 1"}; //This is where I couldn't take it anymore...

Now, I'm open-minded to any sort of explanations about this. My code works, and I know that I can put all my arguments on the selection string since they do not contain any forbidden characters. I only wanted to know, why isn't it working, and why isn't there any mention to this clear limitation on the developer documentation?
