我在Android市场开发者控制台中收到了我的应用程序的错误日志.报告冻结的原因是“ANR keyDispatchingTimedOut”我在用户在相机释放后接受图像后将其追溯到一行代码.按下按钮以接受图像的代码如下：

case R.id.ib_good: // good picture, exit
        //create a new intent...
        Intent i = new Intent();
        i.putExtra("bitmap",path); // path to the temp image we saved

        setResult(RESULT_OK,i); // good job!
        // close the activity

        if (mCamera != null) {
            cv.setCamera(null);
            mCamera.release(); // this is the line that is causing the crash (EDIT: Line 115 in CameraActivity)
            mCamera = null;
        }


        finish();

        break

这是我在开发者控制台中获得的完整堆栈跟踪：

我不知道应该怎么做才能解决这个问题……任何建议都表示赞赏！

解决方法:

在调用.startPreview之前你有没有在任何地方？
这是我的代码如何在应用程序内部使用CameraPreview发布相机.

 camera.setPreviewCallback(null); // PreviewCallback de_init.
 camera.stopPreview();            // stop Preview
 previewActive=false;             // lock_var for check if preview active or not 
 camera.release();                // and finaly release the camera after stop the preview

我希望那就是你要找的……
