Apk在模拟器正常，真机崩溃

Question

模拟器中是安卓5.0的系统，sdk也为21，真机是5.0
在genymotion可以运行，真机安装后一打开就崩溃。

部分Logcat输出：

Answer 1

Skipped 127 frames! The application may be doing too much work on its main thread

意思是指在UI线程执行了耗时长的操作，比如数据库访问，数学计算，数组排序等等。
可以另开线程处理与UI操作无关的事情，或者在主线程中使用AsyncTask。
此方面的范例很多，可以用Thread、Runnable、AsyncTask为关键字搜索。

另外一个可能的原因是使用了过大的图片资源，比如背景图片，图标。
