写真を一定量読み込むとメモリ不足になってしまうのですが
VolleyのImageLoaderを用いてネットからListViewへ写真をロードしています。
キャッシュはLruCacheとImageLoader#ImageCasheを組み合わせています。
ImageLoaderなどはシングルトンです。
確認はエミュレータのNexus5(API22)で行っています。
写真のサイズは縦120dpになるようにしていて、画面上に1枚と2枚目が少し見える程度です。
ListViewは複数あり、それぞれをreplaceして切り替えています。
8ページ目まではスクロールしなければ普通にページ遷移できるのですが、9ページ目でメモリ不足と言われます。
また、前のページでスクロールして3枚以上の写真を見ていると、きちんと見られるページ数が減っていきます。
キャッシュはRuntime.getRuntime().maxMemory()/1024の1/8をmaxSizeとしているはずなのですが、メモリ使用量を見るとページを開くたびにみるみる消費されていて指定したサイズを超えているように見えます。
原因は何が考えられるでしょうか？
キャッシュ用クラスは以下の通りです。
public static class ImageLruCache implements ImageLoader.ImageCache {
private LruCache<String, Bitmap> mMemoryCache;
public ImageLruCache() {
int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
int cacheSize = maxMemory / 8;
mMemoryCache = new LruCache<String, Bitmap>(cacheSize) {
@Override
protected int sizeOf(String key, Bitmap bitmap) {
return bitmap.getByteCount() / 1024;
}
};
}
@Override
public Bitmap getBitmap(String url) {
System.out.println(mMemoryCache.toString());
System.out.println("maxMemory:" + Runtime.getRuntime().maxMemory() / 1024);
System.out.println("totalMemory:" + Runtime.getRuntime().totalMemory() / 1024);
System.out.println("freeMemory:" + Runtime.getRuntime().freeMemory() / 1024);
System.out.println("useMemory:" + ((Runtime.getRuntime().totalMemory() / 1024) - (Runtime.getRuntime().freeMemory() / 1024)));
return mMemoryCache.get(url);
}
@Override
public void putBitmap(String url, Bitmap bitmap) {
mMemoryCache.put(url, bitmap);
}
}
ログは以下の通りです。

追記
ListViewはページによりますが最高で1ページに50枚の写真があります。
そこで、1ページ目を1枚目から順に表示させて反対に50枚目から順に表示させるというのを試してみました。
すると、折り返し2枚分はhitしたようです。
LruCache[maxSize=8192,hits=2,misses=50,hitRate=3%]これは2枚だけキャッシュに存在したということでしょうか？
また、使用量の差がImageLoaderで取得したBitmapのサイズを違うように見えるのですが、
その分はImageViewなどのサイズ分ということになるのでしょうか？
以下のログはその時の一部抜粋です。

また、キャッシュ容量に入る入らないは別として一切キャッシュしないというのを試してみたいのですが、putBitmapでは何もしない、getBitmapではnullを返す、といったことをすれば良いのでしょうか？
その状況で試してもmissesなどが増えないこと以外は状況が変わりませんでした。
追記2
@Override
protected void entryRemoved(boolean evicted, String key,
Bitmap oldValue, Bitmap newValue) {
if (!oldValue.isRecycled()) {
oldValue.recycle();
oldValue = null;
}
}
このように古いBitmapの開放処理を書いたところ、
9ページ目の1枚目ではなく16ページ目の1枚目を表示しようとするまでメモリ不足になりませんでした。
メモリ開放は手動で行わなければならないのですね。
これは2枚だけキャッシュに存在したということでしょうか？
そうなります。
やっとLruCache#toStringした時の項目が理解できました。
ありがとうございます。
RuntimeのメソッドでDalvikヒープの状態を知ることができます
私にはその方法がよくわかりませんでした。
試しにApplication用クラスのonCreateでRuntime.getRuntime().traceMethodCalls(true);と書いてみるとjava.lang.UnsupportedOperationExceptionが発生しました。
どうすれば知ることができるのでしょうか？
アプリはAndroid4.4以降対応で、普段はAndroid Studio付属(?)のエミュレータのNexus5(API 22)を使用しています。
大量の写真のキャッシュにメモリキャッシュはあまり有効じゃないとのことでディスクキャッシュを試そうと思ったのですが、その方法がよくわかりません。
ImageLoaderでディスクキャッシュを使用しようと思ったらどのようにすれば良いのでしょうか？
追記3
ディスクキャッシュについてはVolleyですでに行われているようですが、デフォルトが5MBらしいので10MB・100MB・1GBに変更して試したものの、どれも改善は見られませんでした。
ヒープダンプを見たところ、やはりbyte[]が一番メモリを消費していることがわかりました。
他にはListView用のAdapterクラスがページの数だけメモリに残っていることなどもわかりました。
Adapterクラスがページの数だけ残っているのはページをBackStackに追加しているからでしょうか？
今はいっそVolleyをやめて他を使うなりライブラリ自体を使わないことも検討しています。
