OutofMemoryException while sampling #38

Sampling using DeviceBandwidthSampler.getInstance().startSampling() leading to oom on several devices

QTagParser doesn't exist anymore. Are you running an older version?

Also, it's likely you have another memory leak elsewhere. Usually any code that allocates any memory (in this case 12 bytes), has the potential to trigger an Out of Memory error. It's usually not the cause of the leak though. I suggest doing an HPROF dump of your application and seeing what classes are being held in memory. Usually it's activities or large bitmaps.
