我写了一个Android程序来拍照但没有预览。当我逐步调试它时,我的程序工作正常。但是,当我在执行模式下运行它时,程序无法按预期工作。没有图片保存,程序无法完成。此外,我不能在其他Android应用程序中使用我的相机(例如相机,摄像机),除非我重新启动手机。有人对这个问题有任何想法吗?拍照和记录错误的代码如下:

拍照代码:

    SurfaceView view = new SurfaceView(this);
    mCamera = Camera.open();
    Camera.Parameters p = mCamera.getParameters();
    p.setPictureFormat(PixelFormat.JPEG);
    mCamera.setParameters(p);

    try {
        mCamera.setPreviewDisplay(view.getHolder());
        mCamera.startPreview();
        mCamera.takePicture(null, null, mPictureCallback);
        mCamera.stopPreview();
        mCamera.unlock();
        mCamera.release();
    } catch (Exception e) {
        mCamera.stopPreview();
        mCamera.release();
        e.printStackTrace();            
    }

回调函数

Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
          public void onPictureTaken(byte[] imageData, Camera c) {
               if (imageData != null) {
            StoreByteImage(mContext, imageData, 50,
                    "ImageName");
            finish();
        }
    }
};
}

logcat报告的错误:

任何人都可以提出任何建议吗?提前谢谢

这对你有用吗?

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File file = new File(Environment.getExternalStorageDirectory(),
                    currentTimeString + ".jpg");
            outputFileUri = Uri.fromFile(file);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
            startActivityForResult(intent, TAKE_PICTURE);
