Intermittent crash on Budget devices (of MI, LeEco, Vivo ) on 3G and 2G

[gouravd]

We are observing native crashes only on slower networks (like 3G and 2G connections) on Budget devices of MI, Vivo, LeEco mainly. When we replace with VideoView we don't see these crashes..

I can confirm its not related to a specific file..Here's what I observe

1) The pili most likely is trying and retrying to load/play audio and during this the native memory shoots from 100mb to 700 mb. Whenever it crashes LMK(LowMemoryKiller) is invoked and the native memory usage is in this surge..During this surge the app also frees for 1-2 secs

2) in Build 2.1.0 this surge persisted for longer. In 2.1.2..it decreased in next 5-7 secs...but many times before it can come down the LMK is invoked.

3) This is not observed in Moto phones as LMK does not get invoked even if the available memory is pretty low...but in these above mentioned devices..the LMK is much more aggressive and the issue manifests more frequently

The expectation is that the memory surge/leak should not happen and Pili should call one of the Error states and gracefully fail.

The videos are mostly H24 videos of range 640x480 with <1mbps bitrate and most 1 sec Keyframe interval.. Audio can be AAC-LC, AAC LD- AAC-ELD

JNI DETECTED ERROR IN APPLICATION: JNI NewByteArray called with pending exception java.lang.IllegalStateException: play() called on uninitialized AudioTrack. 我也遇到了这个问题。不知道您解决了没有

Is this solved in 2.1.4?...I see some similar issues fixed in 2.1.3
