Question

每当我运行应用程序时，我都会收到错误Fatal Exception main。该应用程序使用opencv 2.4.10它已在一台设备上运行，但它在我的设备上失败了我无法弄清楚为什么会发生这种情况。

我不知道哪个部分代码导致了这个错误：

请任何解决方案都非常感谢。

显然正在运行的任务正在使用context OpenCBLoader

(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, this, mLoaderCallback))

与context相关的问题，即上下文不再有效。尝试传递getApplicationContext()而不是this

(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_3, getApplicationContext(), mLoaderCallback))

考虑一个AMK（安卓内存杀手）由于内存不足而导致service被杀的情况，因为服务在前台活动之前首先被破坏，现在你的服务已经死了，加上this上下文不是因此有效，因此异常

AndroidRuntime：FATAL EXCEPTION：main：应用程序已停止错误
