Bitmap 现场墙纸被强制关闭的问题
我正在创建一个在xhdpi和ldpi设备上完美运行的实时墙纸应用程序，但在基于hdpi和mdpi的手机上却遇到了强制关闭的问题 当我们点击“设置墙纸”时，它会在预览屏幕中加载图像，甚至当我们从应用程序更改设置时，它也会崩溃 以上两个条件使应用程序强制关闭 看起来像是OutOfMemoryError 错误不一致 这是我的密码： pixeltowo.javaBitmap 现场墙纸被强制关闭的问题,bitmap,live-wallpaper,Bitmap,Live Wallpaper,我正在创建一个在xhdpi和ldpi设备上完美运行的实时墙纸应用程序，但在基于hdpi和mdpi的手机上却遇到了强制关闭的问题 当我们点击“设置墙纸”时，它会在预览屏幕中加载图像，甚至当我们从应用程序更改设置时，它也会崩溃 以上两个条件使应用程序强制关闭 看起来像是OutOfMemoryError 错误不一致 这是我的密码： pixeltowo.java public class pix11two extends SurfaceView { private pix11three three; i
