Android获取app内存使用

 int memSize = 0;
                            if( Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1 ){
                                memSize = getPackageMemoryUsage( topAppName );
                            }else{
                                memSize = getPidMemorySize( getPid() );
                            }

    public int getPackageMemoryUsage(String packagename){
    //dumpsys meminfo com.ztl.helper .然后取 TOTAL那一行
        String sss= FileUtli.execRootCmd("dumpsys meminfo " + packagename);
        Log.e("meminfo","返回" + sss);
        int nIndex = sss.indexOf("TOTAL");
        String subStr = sss.substring(nIndex+9, nIndex + 19); //;( nIndex, 100);
        int eIndex = subStr.indexOf(' ');
        String totalInBytes = subStr.substring(0, eIndex);

        int nTotal = Integer.valueOf(totalInBytes);
        return Integer.valueOf( totalInBytes );
    }

    public int getPidMemorySize(int pid) {
        ActivityManager am = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
        int[] myMempid = new int[] { pid };
        Debug.MemoryInfo[] memoryInfo = am.getProcessMemoryInfo(myMempid);
        memoryInfo[0].getTotalSharedDirty();
        int memSize = memoryInfo[0].getTotalPss();
        return memSize;
    }

方法如上。 因为7.1并不允许其他程序获取别的程序的内存。所以只能曲线救国。
