Abstract

A method of application waste management in a wireless device is provided. The method comprised a first low-memory event. Deleting a first set of data records incrementally until event is cleared or no more records are present. Determining a second low-memory event when memory is still low. Executing a clean-up script to mark additional data records for deletion. Deleting the second set of data records until the second low-memory condition are cleared or no more records are present.

Claims

1. A method of memory management on a wireless device, the method comprising:

determining a first low-memory event when available memory is below a defined threshold;

deleting a first set data records stored in the memory when the first low-memory event is determined, the first set of data records incrementally deleted in order of a priority associated with each data record until the first low-memory condition is cleared or no more of the first set of data records are present;

determining a second low-memory event when available memory is still below a defined threshold after deletion of the first set of data records;

executing a cleanup script on the wireless device, the cleanup scripts marking a second set of data records for deletion and assigning a priority when the second low-memory event occurs; and

deleting the second set data records stored in memory when the second low-memory event is determined, the second set of data records incrementally deleted based in order of priority associated with each data record until the second low-memory condition is cleared or no more of the second set of data records are present.

2. The method of claim 1 wherein one cleanup script is associated with one application currently executing on the wireless device.

3. The method of claim 2 wherein cleanup scripts for each application currently executing on the wireless device is executed when the second low-memory event occurs.

4. The method of claim 1 wherein one cleanup script is associated with a plurality of applications currently executing on the wireless device.

5. The method of claim 1 further comprising providing a visual notification to a user when the second low memory event continues to exists after deleting all possible waste.

6. The method of claim 1 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when an application executing on the wireless device is about to end.

7. The method of claim 1 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when an application executing on the wireless device switches to a background running status.

8. The method of claim 1 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when the wireless device is cradled.

9. The method of claim 1 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when the wireless device is in a sleep mode.

10. A wireless device comprising:

a memory comprising a plurality of data records, each of the data records associated with one or more applications executed on the device;

a processor coupled to the memory, the processor performing;

determining a first low-memory event when available memory is below a defined threshold;

deleting a first set data records stored in the memory when the first low-memory event is determined, the first set of data records incrementally deleted in order of a priority associated with each data record until the first low-memory condition is cleared or no more of the first set of data records are present;

determining a second low-memory event when available memory is still below a defined threshold after deletion of the first set of data records;

executing a cleanup script on the wireless device, the cleanup scripts marking a second set of data records for deletion and assigning a priority when the second low-memory event occurs; and

deleting the second set data records stored in memory when the second low-memory event is determined, the second set of data records incrementally deleted based in order of priority associated with each data record until the second level low-memory condition is cleared or no more of the second set of data records are present.

11. The wireless device of claim 10 wherein one cleanup script is associated with one application currently executing on the wireless device.

13. The wireless device of claim 10 wherein one cleanup script is associated with a plurality of applications currently executing on the wireless device.

14. The wireless device of claim 10 further comprising providing a visual notification to a user when the second low memory event continues to exists after deleting all possible waste.

15. The wireless device of claim 10 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when an application executing on the wireless device is about to end.

16. The wireless device of claim 10 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when an application executing on the wireless device switches to a background running status.

17. The wireless device of claim 10 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when the wireless device is cradled.

18. The wireless device of claim 10 further comprising executing the cleanup script on the wireless device, the cleanup script marking the first set of data records for deletion and assigning the priority when the wireless device is in a sleep mode.

12. The wireless device of claim 12 wherein cleanup scripts for each application currently executing on the wireless device is executed when the second low-memory event occurs.
