そこでPSSというものが存在します。
共有されていないprivateメモリ ＋ 共有されてるメモリ ÷ 共有しているプロセス＝がPSS(Proportional Set Size)です。
グレイト！PSSは本当のメモリサイズとなるのです！
メモリ簡易出力 adb shell procrank adb shell procrank
VSS(Virtual Set Size) 仮想メモリの消費量
RSS(Resident Set Size) 物理メモリの消費量
PSS(Proportional Set Size) プロセスのヒープ所有サイズ
USS(Unique Set Size) プロセスのヒープ利用サイズ
メモリ詳細出力 adb shell dumpsys meminfo パッケージ名 adb shell dumpsys meminfo net.npaka.helloworld
Swap メモリ容量が不足してきたら現在使われていないプロセスを一時的にスワップファイルに書き出し
USS ユニークセットサイズ
PSS ユニークなセットのサイズに加えて使用されている共有メモリの部分である比例セットサイズ
RSS(Resident Set Size) 物理メモリに位置する本当に存在するメモリの量
VSS プロセスが必要とするメモリの量
