查询网上说加载大图片导致，需要在清单文件的application中加上下面两行代码：

 android:largeHeap="true"
 android:hardwareAccelerated="false"

但是我这里是由于RxJava异常导致OOM

解决方案：在Application设置RxJavaPlugin的ErrorHandler

/**
* RxJava2 当取消订阅后(dispose())，RxJava抛出的异常后续无法接收(此时后台线程仍在跑，可能会抛出IO等异常),全部由RxJavaPlugin接收，需要提前设置ErrorHandler
     * 详情：http://engineering.rallyhealth.com/mobile/rxjava/reactive/2017/03/15/migrating-to-rxjava-2.html#Error Handling
*/
private void setRxJavaErrorHandler() {
   RxJavaPlugins.setErrorHandler(new Consumer<Throwable>() {
       @Override
       public void accept(Throwable throwable) throws Exception {
           BLogger.d(TAG, "throw test");
       }
    });
}
