Android应用程序在某些机型上启动有几率一直黑屏

潮起潮落 2014-02-25 10:39:13

我们使用Mono for Android开发了一个App，发现在某些机型上（比如lenovo A3000-H）会打开会出现一直黑屏的情况，进不到程序的界面（同样也定位不到任何调试断点），而有些机型则不会。

通过仔细观察，发现在后台“当前运行程序”一栏，当成功启动时，程序所占体积是21mb左右。当启动失败时（一直黑屏），程序所占体积是9mb左右。

另外通过eclipse监控程序启动日志，对比发现了一些不同。

成功启动时的日志

博主现在解决这个问题了吗？我貌似也遇到类似的问题，我是将程序启动之后放在后台，然后去开启其他的程序但不关闭，这样一直开，开个二三十个程序再点自己的程序，这个时候就一直黑屏

使用4.10.x的mono for andorid，解决了这个问题仍然不清楚根源在哪儿。

就算ERROR。也得让它跑起来。。已经到了最后阶段了。。只差这个大概率黑屏了。
