android：我没有堆栈跟踪，电话只是挂起
Posted
技术标签:
【中文标题】android：我没有堆栈跟踪，电话只是挂起【英文标题】：android: I get no stacktrace, phone just hangs 【发布时间】：2012-01-18 20:45:58 【问题描述】：我的手机在我暂停相机应用程序后崩溃，然后切换回来拍照。 这只发生在我的三星 Galaxy S 上，在我的 Huwai 设备上它完全可以工作。 我找到了导致错误的代码行。不幸的是，这些行非常有用，所以我无法删除它们：
public void surfaceDestroyed(SurfaceHolder holder) // <14>
Log.d(TAG,"surfaceDestroyed()");
if(this.camera != null)
camera.stopPreview();
// the next two lines lead to the error after switching back to the app and taking a picure
camera.release();
this.camera = null;
不幸的是，我没有得到堆栈跟踪。我得到的只是：

有人知道如何解决这个问题吗？
【问题讨论】：
【参考方案1】：我终于（经过几个小时，几乎几天的调试）解决了这个问题，方法是删除预览视图并重新实例化它：
@Override
protected void onResume()
super.onResume();
mSurfaceViewContainer.removeAllViews();
mSurfaceView = new SurfaceView(mSurfaceViewContainer.getContext());
mSurfaceViewContainer.addView(mSurfaceView, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
SurfaceHolder previewHolder = mSurfaceView.getHolder();
previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
previewHolder.addCallback(mSurfaceHolderCallback);
【讨论】：
美丽。删除并重新创建预览和容器在很多方面都有帮助。【参考方案2】：抛出了一个 IOException (Could not find method java.io.IOException.<init>)，但是 IOException 构造函数使用了was introduced in API level 9，所以它在 Galaxy S 上不存在，而是显示一个奇怪的日志。
关于您的问题，我建议尝试在release() 之前致电lock() ：
camera.stopPreview();
camera.lock();
camera.release();
this.camera = null;
我不知道这是否可行，但在this source code，我发现一条评论说：
// If we don't lock the camera, release() will fail.
camera.lock();
camera.release();
似乎很明显相关。
【讨论】：
感谢您的提示，但这并没有改变任何事情：/以上是关于android：我没有堆栈跟踪，电话只是挂起的主要内容，如果未能解决你的问题，请参考以下文章
