由于标题中的上述错误，我现在在我的应用程序项目中停留了很长一段时间。我知道还有很多其他主题，我已经尝试了几种解决方案，但似乎没有一个能解决我的问题。
到目前为止我尝试了什么:
- 增加 ADB 连接超时(毫秒)
- 更改了此处建议的环境路径变量:http://anandpandia.blogspot.nl/2011/01/failed-to-install-helloandroidapk-on.html
- 重启我的手机
- 在 list 文件中将安装位置更改为外部
这个问题似乎与应用程序的大小有关。在我添加一些 mp3 文件之前，它工作正常。我认为该应用程序现在大约有 150MB。我的内部磁盘和 SD 上都有足够的空间。

最佳答案
你清理项目了吗？添加新资源时，必须先清理项目，然后再重建。
如果您使用的是 Eclipse，请单击“项目”->“清理...”并清理所有项目。 如果您使用命令行，请在项目目录中键入“ant clean”。
现在尝试重建项目。
