android 监听其它app的错误或者崩溃的方法 （ProcessErrorStateInfo）

具体请参见android源码：ProcessErrorsTest.java

private String checkForProcessErrors() throws Exception {

List<ProcessErrorStateInfo> errList;

errList = mActivityManager.getProcessesInErrorState();

// note: this contains information about each process that is currently in an error

// condition. if the list is empty (null) then "we're good".

// if the list is non-empty, then it's useful to report the contents of the list

final String reportMsg = reportListContents(errList);

return reportMsg;

}
