I am seeing a memory/resource leak after 3-4 hours of media play under
the following conditions:
1. Android 1.6
2. OTA (over-the-air) streaming.
3. AAC v1 or AAC v2 content.
If any of those variables change, I do not see the issue -- i.e.
Android 1.5 and 2.0 do not have this problem, WiFi streaming or local
file playback does not have this problem, streaming MP3 content does
not have this problem.
I have created a "hello world" test application which exhibits this
problem. The only purpose of this test application is to demonstrate
this problem (not coding style / error checking, etc...). After
approximately 3-4 hours of playback, the phone (T-Mobile G1 or G2)
becomes very sluggish and even simple things like hitting the "home"
button can take a very long time.
Any help *greatly* appreciated.
tia.
