Sure, I'd be happy to help! Before providing the examples, let's understand the exception `android.database.CursorWindowAllocationException` and what could cause it.

What is `android.database.CursorWindowAllocationException`?

This exception occurs when the CursorWindow has reached its memory allocation limit. CursorWindow is a fixed-size buffer allocated from the native heap that stores the results of a query, making it available for processing in Android SQLite databases.

Possible Causes:

– Fetching a large amount of data from the database

– Reading large columns like BLOB or TEXT

– Keeping a Cursor open for a long time

– Not closing the Cursor properly

To demonstrate this issue, I will provide you with six different examples to help you understand the different scenarios that could lead to `android.database.CursorWindowAllocationException`.

Let's start with the examples:

Example 1: Fetching a large number of rows

             java
Cursor cursor = db.rawQuery("SELECT * FROM my_table", null);
while (cursor.moveToNext()) {
    // Process the data
}

             

This code queries a table `my_table` and iterates through the results. If `my_table` contains a large number of rows, the CursorWindow may exceed its memory allocation limit.

Output:

If `my_table` has too many rows, this code snippet may throw `android.database.CursorWindowAllocationException`.

I will provide more examples in a similar format to cover different scenarios. Let me know if you need further clarification or have any questions.
