Android Java Space OOM

The default Android java space heap maximum limitation is 16M. If you are running multimedia applications on android, such as jpg file decoding, video decoding, you may run OOM (Out Of Memory). If memory tuning can not help you on the OOM, you can go to the file: frameworks/base/core/jni/AndroidRuntime.cpp, line 607, change opt.optionString = "-Xmx16m" to opt.optionString = "-Xmx20m" for 20M heap size or even bigger.
The limitation is the upward limitation, it will not actually allocate 20M memory every time in every java application.
Take this solution as the last try, focus on your coding quality first.

Android OS based smartphones have been selling really well during the last few months, and some of the credit must go the large number of apps that are being created for android smartphones.
