问题与使用Android相机拍照相机、问题、Android

我有一个应用程序在那里我使用了Android相机拍摄pictures.I已经建立了自己的Android camera.And照片是由pressing一个按钮。

I have an app where I'm using the android camera to take pictures.I have built my own android camera.And pictures are taken by pressing a button.

事情是这样的：

  public void onClick(View arg0) {
  mCamera.takePicture(null, mPictureCallback, mPictureCallback);
  }


Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
    public void onPictureTaken(byte[] imageData, Camera c) {

        if (imageData != null) {
            Intent mIntent = new Intent();


            Bundle b = new Bundle();
            b.putByteArray("imageData", imageData);
            Intent i = new Intent(mContext, ViewPhoto.class);
            i.putExtras(b);
            startActivity(i);

            setResult(FOTO_MODE, mIntent);
            finish();

        }
    }
};

在拍摄照片后我使用意图和发送的字节数到另一个活动。

Once the picture is taken I use an intent and send the bytes to another activity.

最大的问题是，如果我把多张照片，一个个由pressing按钮，我的应用程序崩溃，在这一行：

The big problem is that if I take several photos, one by one by pressing the button, my app crashes at this line:

mCamera.takePicture(null, mPictureCallback, mPictureCallback);

这是我的logcat的样子：

This is how my logcat looks like:

java.lang.RuntimeException: takePicture failed

不知道如何解决这个问题？
