Görüntüleyicisini bir Görüntülü Reklam Birimine yüklerken hata oluştu. Cn.trinea.android.view.autoscrollviewpager: google otomatik kaydırma-görünüm-çağrı cihazı: 1.1.2 kütüphanesini kullanarak bir Viewpager'ım var. Bir OOM hatası alıyorum (aşağıya bakın). Bir ViewPager'ı, bir TabManager ile kullandığım bir View Pager'de oturan bir parçada (aşağıya bakın) bulunan yukarıdaki kütüphaneyi kullanarak arıyorum.Bellek Dolu Resim
DÜZENLEME aşağıdaki görevleri denedik: bitmap geri dönüştürmek için bir adım daha
- mainfest

- (aşağıdaki öneri göre kaldırıldı) Eklenen önerdi bitmap görüntüleri
- Eklendi
- Eklendi bitmap İşçi Görevler android öneri başına Önbellek

Hiçbir şey değişmedi ama belki de resimlerin boyutu (resimlerin tümü aslında boyut olarak düştü). Bir önceki etkinliğe, bu bölümün yüklenmesinden önce, önbellek dizinine beş resim yüklüyorum, sonra da orada olup olmadıklarını ve indirilmediklerini kontrol ediyorum.
Ben görüntüleri geri dönüşüm, yığın boyutunu artırarak denedim (adaptörün destroyItem bakınız ben aşağıdaki hatayı alıyorum adaptörü başlatmak için denemek yerine ne zaman.

çok yapmanız ama daha küçük bitmapler kullanabilirsiniz Değil. Ayrıca, bir ImageView içine yerleştirdikten sonra bitmapinizi hemen geri dönüştürmeyin. ImageView'ın doğru bir şekilde çizilmesi için tam olarak tahsis edilmesi gerekir. –
Bunun ötesinde, 'recycle()' işlevine değil, “bitmap” nesnelerini taze bitmap'lere yüklemek için * tekrar * kullanmaya çalışın (BitmapFactory.Options'daki 'InBitmap' bölümüne bakın). En iyi zamanlarda 4MB'lik bir tahsis zor. Bir kez sahip olduğunuzda, sadece tekrar ihtiyacınız olmayacağından emin olduğunuzda bırakın.Sabit dağıtımlar ve sürümler, özellikle Android 4.4 ve sonraki sürümlerde yığınınızı parçalara ayıracak. – CommonsWare
