Question

我在6.0版的Android Studio中使用模拟器遇到了上述崩溃，但我的设备6.0.1没有崩溃。模拟器有时会启动相机，但它主要在logcat中没有任何东西崩溃，以指向正确的方向。有没有人知道这里可能会发生什么？

此外，这是一张真正经历的图片。 Image_capture_camera

private File createImageFile() throws IOException
{
    // Create an image file name
    String timeStamp = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss").format(new Date());
    String imageFileName = "" + timeStamp;
    File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    Name = imageFileName;
    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

private void dispatchTakePictureIntent()
{
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null)
    {
        // Create the File where the photo should go
        File photoFile = null;
        try
        {
            photoFile = createImageFile();
        }
        catch (IOException ex)
        {
            // Error occurred while creating the File
        }
        // Continue only if the File was successfully created
        if (photoFile != null)
        {
            photoURI = FileProvider.getUriForFile(getActivity(),
                    "com.full.jusuf.snaphealth.fileprovider",
                    photoFile);
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK)
    {

        final Uri uri = photoURI;
        uri_data.add(new Timeline_Model(uri.toString(), Name));

        //save data to firebase
        FirebaseStorage storage = FirebaseStorage.getInstance();
        StorageReference storageRef = storage.getReference().child("users").child(FirebaseAuth.getInstance().getCurrentUser().getUid());
        storageRef.child(FirebaseAuth.getInstance().getCurrentUser().getUid()).child(Name).putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot)
            {
                String uri1  = taskSnapshot.getDownloadUrl().toString();
                FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference();
                if (user != null)
                {
                    long Count = System.currentTimeMillis();
                    databaseReference.child("users").child(user.getUid()).child("image_uri").child("image" + Count).setValue(new Timeline_Model(uri1, Name));
                }
            }
        });

        PopulateGallery();
    }
}

正如您可能知道的那样，Android 23完全更改了权限策略，因此如果您的目标是23+（或者您可能做的最新版本），那么您的问题很可能就在这里

File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
        imageFileName,  /* prefix */
        ".jpg",         /* suffix */
        storageDir      /* directory */
);

或在这里

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

（请阅读：Android M Camera Intent + permission bug?）

确保你有

 < uses-permission android:name="android.permission.CAMERA" />

 < uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

在您的清单中

，然后转到设置 - ＆gt;应用 - ＆gt; yourApp - ＆gt;权限，并确保选中存储和相机。如果您的崩溃不再使用手动设置的权限重现，请继续阅读 https://developer.android.com/training/permissions/requesting.html 并将运行时权限请求添加到应用程序使用的所有功能中。

不幸的是相机已经停止了android 6.0.0的错误
