java - android.view.WindowLeaked 后 Camera Intent

Question

我正在通过 Eclipse 开发一个 Android 应用程序，我在查找导致以下错误的原因时遇到了一些问题:

我正在调用一个 ACTION_IMAGE_CAPTURE Intent 来打开相机，并期望在结果上显示图像。所以:

Intent v_Intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try 
{
    v_Intent.putExtra(MediaStore.EXTRA_OUTPUT,   Uri.fromFile(createImageFile()));
} 
catch (IOException e)
{
    Builder v_Builder = new AlertDialog.Builder(GroupPageActivity.this);
    v_Builder.setIcon(android.R.drawable.ic_dialog_alert);
    v_Builder.setTitle("Arquivo não Anexado");
    v_Builder.setMessage(R.string.cameraSaveErrorInfo).setNegativeButton("OK", null).show();
    e.printStackTrace();
    return;
}
v_Intent.putExtra("return-data", true);
GroupPageActivity.this.startActivityForResult(v_Intent, IMAGE_CAMERA_REQUEST_ATTACHMENT_CODE);

在这里期待它:

protected void onActivityResult(int p_Code, int p_Result, Intent p_Intent)
    {
    if (p_Result != RESULT_CANCELED)
        {
            switch (p_Code)
            {
             ...
            case IMAGE_CAMERA_REQUEST_ATTACHMENT_CODE:
                {
                    if (p_Intent != null)
                    {
                        Uri capturedImageUri = p_Intent.getData();
                        //capturedImageUri = g_ImageUri;
                        if (capturedImageUri != null)
                        {
                            m_ImageUriList.add(capturedImageUri);
                            new CallAddThumbnails().execute();
                        }
                        else {
                            Builder v_Builder = new AlertDialog.Builder(GroupPageActivity.this);
                            v_Builder.setIcon(android.R.drawable.ic_dialog_alert);
                            v_Builder.setTitle("Arquivo não Anexado");
                            v_Builder.setMessage(R.string.cameraImageErrorInfo).setNegativeButton("OK", null).show();
                        }
                    }
                    else
                    {
                        Uri capturedImageUri = Uri.parse(g_CurrentPhotoPath);
                        m_ImageUriList.add(capturedImageUri);
                        new CallAddThumbnails().execute();
                    }
                    break;
                }
            }    
        }
    }

我能够启动相机 Activity ，拍摄照片，但是，有时，并非总是，我得到这个:

调用在此 GroupPageActivity 上。而且我确信，当它发生时，它会在调用 onActivityResult 之前崩溃。

有什么想法吗？

PS.: 我在这里抛出另一个异常:

Private Phone m_UserPhone = ConfigurationController.GetActiveNotNull();

这是 GroupPageActivity 的成员。

PS2.:我注意到，当我拍照时，从 Eclipse 到我正在调试的设备的调试连接在相机 Activity 中终止了。当我确认拍摄的照片时，它崩溃了。

去掉这一行再试一次...

v_Intent.putExtra(MediaStore.EXTRA_OUTPUT,   Uri.fromFile(createImageFile()));

发生这种情况是因为 uri 泄漏异常...最好不要将 uri 传递给获取文件的 Intent
