三星平台上的测试心得

这几天在整一apk，有个问题发现只有在三星4.0以上系统会出现，其余安卓手机系统则不会。html

问题时这样的：java

程序须要调用摄像头取照片和拍视频，在Activity中发送一个Intent，给这个Intent填一个媒体输出地址----uri，我在Activity中申明一个全局变量：private Uri uri = null;android

uri在后续代码中赋值，在我发出Intent（startActivityForResult(intent)）以前加日志打印，uri是有值的，但取到照片或者视频后，这个uri变成了null（在onActivityResult()中），我之前一直觉得全局变量要在这个类销毁掉后才销毁的，如今发现三星好像不是这样的。固然简单的解决方法是把变量弄成静态的。app

另外还有一个问题，也是在三星上才出现：oop

一样是在onActivityResult()方法中，我有申明一个弹出框AlertDialog dialog = AlertDialog.Builder(context).create();结果出现这样的错误：ui

首先这个错误只在三星上出现，其次，stackOverFlow上说这样的错误通常都是在Activity销毁钱对话框没销毁形成的，但我这明显不是这样。还有一种状况，就是在非UI线程中作了显示对话框的操做，我开始觉得三星的系统是否定为onActivityResult()中不是主线程。但后来我放到handler中去作也没解决。这个问题如今还没找到解决方法，若是有大神路过，就请不吝赐教。若是我后面解决了，后面把方法补上。spa
