我正在使用以下代码从相机获取图片。除了三星,它在其他手机上运行良好。请让我知道我做错了什么。

 final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "temp" + File.separator);
        root.mkdir();
        final String fname = "img_" + System.currentTimeMillis() + ".jpg";
        final File sdImageMainDirectory = new File(root, fname);
        outputFileUri = Uri.fromFile(sdImageMainDirectory);

        // Camera.
        final List<Intent> cameraIntents = new ArrayList<Intent>();
        final Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        final PackageManager packageManager = cordova.getActivity().getPackageManager();
        final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
        for (ResolveInfo res : listCam){
            final String packageName = res.activityInfo.packageName;
            final Intent intent = new Intent(captureIntent);
            intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            intent.setPackage(packageName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
            cameraIntents.add(intent);
        }

        //FileSystem
        final Intent galleryIntent = new Intent();
        galleryIntent.setType("image/jpeg");
        galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

        // Chooser of filesystem options.
        final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Image Source");
        // Add the camera options.
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));
        startActivityForResult(chooserIntent, PICK_FILE_REQUEST);

以及活动结果
 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == PICK_FILE_REQUEST) {
             if(data!=null){
                Logv("Data","got some data");
              }
           }
    }

最佳答案

不,它只在您尝试过的设备上使用相机应用程序。它通常不适用于ACTION_IMAGE_CAPTURE
请让我知道我做错了什么
您假设ACTION_IMAGE_CAPTURE应该返回一个结果IntentIt is not required when you provide EXTRA_OUTPUT。您知道您要求将图像保存到哪里(您提供给EXTRA_OUTPUT的值),因此请在那里查找图像。
请注意,有些有问题的相机应用程序会忽略EXTRA_OUTPUT(将图像存储在它们想要的位置),因此,如果您的ACTION_IMAGE_CAPTURE请求中的图像不在EXTRA_OUTPUT中,则您将失去运气。
