机器人 - 如何让我的Android设备的内存使用情况 [英] android - How to get Memory usage of my android device
问题描述
您的朋友是如何做的，希望最好的。 朋友，我想怎么有多少内存我的Android设备确实有多少内存使用 活动内存，活动内存，可用内存和MB有线内存 我已经通过<一个了href="http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android">this链接它说关于通过解析/系统/斌/猫，的/ proc / meminfo中，我们可以得到我上面提到的事情，是的，我让所有的事情，但我得到一个长字符串在这里我拥有了一切。

更大的字符串这个我收到来自
私人字符串ReadCPUinfo（）
{
的ProcessBuilder CMD;
StringBuffer的strMemory =新的StringBuffer（）;
//最后ActivityManager activityManager =（ActivityManager）
context.getSystemService（Context.ACTIVITY_SERVICE）;
ActivityManager actvityManager =（ActivityManager）this.getSystemService（
ACTIVITY_SERVICE）;
ActivityManager.MemoryInfo明复=新ActivityManager.MemoryInfo（）;
actvityManager.getMemoryInfo（明复）;
strMemory.append（可用内存：）;
strMemory.append（mInfo.availMem / 1048576L）;
strMemory.append（\ N）;
strMemory.append（\ N）;
字符串结果= strMemory.toString（）;
尝试{
字串[] args = {/系统/斌/猫，的/ proc / meminfo中};
CMD =新的ProcessBuilder（参数）;
工艺过程= cmd.start（）;
在的InputStream = process.getInputStream（）;
byte []的重新=新的字节[1024];
而（in.read（再）！= -1）{
的System.out.println（itthhe ==== ---＆GT;＆GT;＆GT;＆GT;+新的String（重新））;
结果=结果+新的String（重）;
}
附寄（）;
}赶上（IOException异常前）{
ex.printStackTrace（）;
}
返回结果;
}
我想我是否可以动态地打破这个字符串差异。设备或是否有任何其他的方法找出上面的东西
我也通过
任何帮助深表AP preciated 感谢adavance
ActivityManager activityManager =（ActivityManager）context.getSystemService（ACTIVITY_SERVICE）;
MemoryInfo memoryInfo =新ActivityManager.MemoryInfo（）;
activityManager.getMemoryInfo（memoryInfo）;
Log.i（TAG，memoryInfo.availMem+ memoryInfo.availMem +\ N）;
Log.i（TAG，memoryInfo.lowMemory+ memoryInfo.lowMemory +\ N）;
Log.i（TAG，memoryInfo.threshold+ memoryInfo.threshold +\ N）;
名单＆LT; RunningAppProcessInfo＆GT; runningAppProcesses = activityManager.getRunningAppProcesses（）;
地图＆LT;整数，字符串＆GT; pidMap =新TreeMap的＆LT;整数，字符串＆GT;（）;
对于（RunningAppProcessInfo runningAppProcessInfo：runningAppProcesses）
{
pidMap.put（runningAppProcessInfo.pid，runningAppProcessInfo.processName）;
}
收藏＆LT;整数GT;键= pidMap.keySet（）;
对于（INT键：键）
{
INT的PID [] =新INT [1];
PID的[0] =键;
android.os.Debug.MemoryInfo [] memoryInfoArray = activityManager.getProcessMemoryInfo（PID）的;
对于（android.os.Debug.MemoryInfo pidMemoryInfo：memoryInfoArray）
{
Log.i（TAG，的String.Format（** meminfo中的PID％D [％S] ** \ N，PID的[0]，pidMap.get（PID的[0]）））;
Log.i（TAG，pidMemoryInfo.getTotalPrivateDirty（）：+ pidMemoryInfo.getTotalPrivateDirty（）+\ N）;
Log.i（TAG，pidMemoryInfo.getTotalPss（）：+ pidMemoryInfo.getTotalPss（）+\ N）;
Log.i（TAG，pidMemoryInfo.getTotalSharedDirty（）：+ pidMemoryInfo.getTotalSharedDirty（）+\ N）;
}
}

这就是你所需要的;）
how you friends are doing, hope for the best. friends i want to how how much memory my android device does have and how much memory is used active memory , inactive memory, free memory and wired memory in MB i have gone through this link which says about that by parsing "/system/bin/cat", "/proc/meminfo" we can get things which i mentioned above, and yes i am getting all the things but i am getting a long string where i have everything

even bigger string this i am getting from
private String ReadCPUinfo()
{
ProcessBuilder cmd;
StringBuffer strMemory = new StringBuffer();
//final ActivityManager activityManager =(ActivityManager)
context.getSystemService(Context.ACTIVITY_SERVICE);
ActivityManager actvityManager = (ActivityManager) this.getSystemService(
ACTIVITY_SERVICE );
ActivityManager.MemoryInfo mInfo = new ActivityManager.MemoryInfo ();
actvityManager.getMemoryInfo( mInfo );
strMemory.append("Available Memory : ");
strMemory.append(mInfo.availMem/1048576L);
strMemory.append("\n");
strMemory.append("\n");
String result=strMemory.toString();
try{
String[] args = {"/system/bin/cat", "/proc/meminfo"};
cmd = new ProcessBuilder(args);
Process process = cmd.start();
InputStream in = process.getInputStream();
byte[] re = new byte[1024];
while(in.read(re) != -1){
System.out.println("itthhe ==== --- >>>> "+new String(re));
result = result + new String(re);
}
in.close();
} catch(IOException ex){
ex.printStackTrace();
}
return result;
}
i want to whether i can break this string dynamically for diff. devices or is there any other way to find out above things
i have also gone through this but it was also not that use full .. i am easily able to get available memory info but i need all four
any help is deeply appreciated thanks in adavance
