Picasso Библиотека Исключение аварий

Question

У меня есть проблема с Пикассо, я получил аварии:

Fatal Exception: java.util.concurrent.RejectedExecutionException: Task com.squareup.picasso.PicassoExecutorService$PicassoFutureTask@41a39a38 rejected from com.squareup.picasso.PicassoExecutorService@41acc1d0[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0]

    at android.os.Looper.loop(Looper.java:153) 
    at android.os.HandlerThread.run(HandlerThread.java:60) 

Это, как я создаю Пикассо в onResume():

final Picasso.Builder builder = new Picasso.Builder(context); 
    builder.indicatorsEnabled(BuildConfig.DEBUG); 
    builder.defaultBitmapConfig(Bitmap.Config.RGB_565); 

    final long cacheSize = (long) (getAvailableRam() * 0.5F); 

    builder.memoryCache(new LruCache((int) cacheSize)); 
    builder.listener(_listener); 
    _picasso = builder.build(); 

и OnPause():

if (_picasso != null) { 
     _picasso.shutdown(); 
     _picasso = null; 
    } 

Любые предложения?

Возможно, проблема в выключении. Я предлагаю, чтобы отменить все задания до и затем выключения Picasso :)

Простое быстрое решение.

Использование одного экземпляра для Picasso

/** Stops this instance from accepting further requests. */ 
    public void shutdown() { 
    if (this == singleton) { 
     throw new UnsupportedOperationException("Default singleton instance cannot be shutdown."); 
    } 
    if (shutdown) { 
     return; 
    } 
    cache.clear(); 
    cleanupThread.shutdown(); 
    stats.shutdown(); 
    dispatcher.shutdown(); 
    for (DeferredRequestCreator deferredRequestCreator : targetToDeferredRequestCreator.values()) { 
     deferredRequestCreator.cancel(); 
    } 
    targetToDeferredRequestCreator.clear(); 
    shutdown = true; 
    } 

Проверил:

public void cancelTag(Object tag) { 
    checkMain(); 
    if (tag == null) { 
     throw new IllegalArgumentException("Cannot cancel requests with null tag."); 
    } 

    List<Action> actions = new ArrayList<Action>(targetToAction.values()); 
    //noinspection ForLoopReplaceableByForEach 
    for (int i = 0, n = actions.size(); i < n; i++) { 
     Action action = actions.get(i); 
     if (tag.equals(action.getTag())) { 
     cancelExistingRequest(action.getTarget()); 
     } 
    } 

    List<DeferredRequestCreator> deferredRequestCreators = 
     new ArrayList<DeferredRequestCreator>(targetToDeferredRequestCreator.values()); 
    //noinspection ForLoopReplaceableByForEach 
    for (int i = 0, n = deferredRequestCreators.size(); i < n; i++) { 
     DeferredRequestCreator deferredRequestCreator = deferredRequestCreators.get(i); 
     if (tag.equals(deferredRequestCreator.getTag())) { 
     deferredRequestCreator.cancel(); 
     } 
    } 
    }
