在看到上述代码之前，自己按照API说明也写了类似代码如下，包含了更多的输出参数。如果要检查其他进程的内存使用情况，可略去循环中的条件判断。 按stackoverflow.com中帖子的说法 Pss的值是最能表明进程使用内存状况
public long getmem_SELF() {
ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> procInfo = am.getRunningAppProcesses();
for (RunningAppProcessInfo runningAppProcessInfo : procInfo) {
System.out.println(runningAppProcessInfo.processName+ String.format
(",pid = %d", runningAppProcessInfo.pid));
if( runningAppProcessInfo.processName.indexOf(this.getPackageName()) != -1 )
{
int pids[] = {runningAppProcessInfo.pid};
Debug.MemoryInfo self_mi[] = am.getProcessMemoryInfo(pids);
StringBufferstrbuf = new StringBuffer();
strbuf.append(" proccess Name:").append(runningAppProcessInfo.processName)
