在做Andriod应用性能相关的测试中，很关心的一点就是应用所占用的内存了。

我们知道可以通过 adb shell dumpsys meminfo + 包名命令来获取应用占用的内存，但是在代码中怎么获取呢？

这里我们需要用到 Debug.MemoryInfo 这个类。

获取本应用占用内存的方法：

@TargetApi(Build.VERSION_CODES.KITKAT)public static int getMemory() {Debug.MemoryInfo memoryInfo = new Debug.MemoryInfo();Debug.getMemoryInfo(memoryInfo);        // dalvikPrivateClean + nativePrivateClean + otherPrivateClean;int totalPrivateClean = memoryInfo.getTotalPrivateClean();// dalvikPrivateDirty + nativePrivateDirty + otherPrivateDirty;int totalPrivateDirty = memoryInfo.getTotalPrivateDirty();// dalvikPss + nativePss + otherPss;int totalPss = memoryInfo.getTotalPss();// dalvikSharedClean + nativeSharedClean + otherSharedClean;int totalSharedClean = memoryInfo.getTotalSharedClean();// dalvikSharedDirty + nativeSharedDirty + otherSharedDirty;int totalSharedDirty = memoryInfo.getTotalSharedDirty();// dalvikSwappablePss + nativeSwappablePss + otherSwappablePss;int totalSwappablePss = memoryInfo.getTotalSwappablePss();        int total = totalPrivateClean + totalPrivateDirty + totalPss + totalSharedClean + totalSharedDirty + totalSwappablePss;        return total ;}
