解决OOM问题，自测已没问题，初始化Fresco时，要添加如下内容：
private void initFresco() {
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
ImagePipelineConfig imagePipelineConfig = ImagePipelineConfig
.newBuilder(getApplicationContext())
.setDownsampleEnabled(true)
.setBitmapMemoryCacheParamsSupplier(new LollipopBitmapMemoryCacheParamsSupplier(activityManager))
.build();

    Fresco.initialize(getApplicationContext(), imagePipelineConfig);
}

public class LollipopBitmapMemoryCacheParamsSupplier implements Supplier {

private ActivityManager activityManager;

public LollipopBitmapMemoryCacheParamsSupplier(ActivityManager activityManager) {
    this.activityManager = activityManager;
}

@Override
public MemoryCacheParams get() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        return new MemoryCacheParams(getMaxCacheSize(), 56, Integer.MAX_VALUE,
                Integer.MAX_VALUE,
                Integer.MAX_VALUE);

// 不确定用哪个
// return new MemoryCacheParams(getMaxCacheSize(), 1, 1, 1, 1);
} else {
return new MemoryCacheParams(
getMaxCacheSize(),
256,
Integer.MAX_VALUE,
Integer.MAX_VALUE,
Integer.MAX_VALUE);
}
}

private int getMaxCacheSize() {
    final int maxMemory = Math.min(activityManager.getMemoryClass() * ByteConstants.MB, Integer.MAX_VALUE);

    if (maxMemory < 32 * ByteConstants.MB) {
        return 4 * ByteConstants.MB;
    } else if (maxMemory < 64 * ByteConstants.MB) {
        return 6 * ByteConstants.MB;
    } else {
        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD) {
            return 8 * ByteConstants.MB;
        } else {
            return maxMemory / 4;
        }
    }
}

}
