我正在使用Andengine GLES2 Anchor中心分支开发动态壁纸，基于Development Cookbook.Wallpaper在中高端设备上运行良好，但在低端设备上显示出问题。我在三星Galaxy ace，Micromax上进行了测试Funbook平板电脑和问题发生器三星Galaxy Y.问题只发现在三星Galaxy Y上我唯一的低端设备。
问题
当有时解锁屏幕时，或者当有时返回主页时，我失去了所有精灵的纹理，错误不是以可预测的方式生成的，有时它根本不会导致任何问题，但是当它发生时我的工作甚至在我的预览模式下我必须强制关闭应用程序并再次启动应用程序。
这些是我的动态壁纸的细节， 壁纸有一个背景精灵，一个主图像精灵，两个带有一些初始化器和修饰符的BatchedSpriteParticleSystem 我在资产中有一个sepretae文件夹用于低端设备（320 * 480），我保留小图像并将所有图像加载到单个纹理图集中，在这种情况下，其他方面我使用两个纹理图集一个用于背景图像，一个用于我的主图像和两个粒子图像。我正在使用资源管理器calss根据andengine cookbook加载纹理
请帮我解决这个问题，我不知道我在哪里出错了 这是我的代码......

请帮我解决这个问题，我欢迎所有的想法建议，有任何想法，你解决这个问题....
答案 0 :(得分：2)
我注意到Galaxy Y有很多问题，我的游戏收到很多崩溃报告，直到我阻止它们下载它并且所有报告都停止了[它是唯一有问题的设备]
我建议你做同样的事情
编辑： 如果您想选择支持哪些设备，可以使用此示例
<supports-screens
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="false"
android:anyDensity="true" />
根据需要修改
