Question

我正在尝试在我的Android应用中使用Samsung Spen Sdk，但有时会导致我的应用冻结。

我已在GitHub（下面的链接）上传了示例代码以供参考。该应用程序启动包含SCanvasView的Activity。如果用户在加载新活动之前多次单击启动按钮，则会出现问题。如果您运行示例代码并快速点击“启动操作”按钮，它将加载新活动。但是，当您完成该活动时，应用程序将冻结。

有关如何解决这个问题的建议吗？

我正在使用Galaxy Note 8.0。＆安培; S Pen SDK 2.3

Answer 1

我不知道为什么会这样，但我能够通过确保在SCanvasInitializeListener中将SCanvasView.setFingerControlPenDrawing（）设置为true而不是false来修复它。

显然，默认情况下启用手指绘制无法启动SCanvasView类。

三星SCanvasView导致ANR
