我已将相机功能包含在我的应用程序中.我也在市场上推出了这款应用.我收到一个用户的错误消息,说他在打开相机时出错了.

我在2.1上测试了设备上的应用程序.我从用户那里得到的错误是使用nexus,它主要运行2.2 ...这是我收到的logcat错误...

我在2.2模拟器上运行应用程序也检查它.但它运作良好.谁能告诉我为什么会发生错误？

这是我在评论中提到的课程:

class Preview extends SurfaceView implements SurfaceHolder.Callback 
{
    private static final String …

我正在使用android内置摄像头拍照,然后将相同的图片附加到电子邮件,当我在1.6设备中测试此功能时,我能够在内置摄像头中命名要拍摄的图片,但在2.1中,图片是有一个名字,即由设备给出,

如何在2.1内置摄像头图像中提供用户定义的名称..

为了避免这个问题,我手动保存图像,但是当我尝试通过意图将图像作为位图返回,然后使用压缩方法将其保存到SD卡

此方法处理内置摄像头的结果

protected void onActivityResult(int requestCode, int resultCode, Intent data)
 {
  File file = new File(Environment.getExternalStorageDirectory()
    + "/test.png");
  switch (requestCode)
  {
  case PHOTO_ACTION:
   if (resultCode == RESULT_CANCELED)
   {
     addPhoto = false;
     Toast.makeText(this, "Canceled ", Toast.LENGTH_LONG).show();
     break;
   } else if (resultCode == RESULT_OK)
   {
    Bundle b = data.getExtras();
    Bitmap bm = (Bitmap) b.get("data");

    FileOutputStream out;
    try
     {

     out = new FileOutputStream(file);
     bm.compress(Bitmap.CompressFormat.JPEG, 100, out);
     out.flush();
     out.close();
     scanPhoto(file.toString());
     out = null;
     addPhoto = true;
     } catch (Exception e)
      {
       e.printStackTrace(); …
