Android:将操作系统版本更新为5.1.1时,Image Crop崩溃

Question

我将我的nexus 5 Android操作系统版本更新为5.1.1,并更新了Google相机和Google相册应用程序.在此之后,当我尝试捕获图像并裁剪它时,我的应用程序崩溃并出现以下错误:

以前它工作正常.我使用的代码如下:

图像捕获代码:

try {
    Intent imageCapture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (imageCapture.resolveActivity(getContext().getPackageManager()) != null) {
        imageCapture.putExtra(MediaStore.EXTRA_OUTPUT,  Uri.fromFile(new File(Environment.getExternalStorageDirectory().getAbsolutePath() + Constants.image_path)));
        startActivityForResult(imageCapture, Constants.CAMERA_IMAGE_CAPTURE);
    }
} catch (ActivityNotFoundException anfe) {
    Toast.makeText(getContext(), "device doesn't support capturing images!", Toast.LENGTH_SHORT).show();
}

图像裁剪代码

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        if (resultCode == RESULT_OK) {
            if (requestCode == CAMERA_IAMGE_CROP) {
                Bundle extras = intent.getExtras();//intent.getExtras() is always returns NULL here         
                Bitmap thePic = extras.getParcelable("data");
                //setImageOnImageView(thePic);
            } else if (requestCode == Constants.CAMERA_IMAGE_CAPTURE)) {
                processCapturedImage();
            }
        }
    }

    private void processCapturedImage() {
        try {
            String path = Environment.getExternalStorageDirectory().getAbsolutePath() + Constants.image_path;
            File file = new File(path);
            if (file.exists()) {
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inPreferredConfig = Bitmap.Config.RGB_565;
                Bitmap bm = BitmapFactory.decodeFile(path, options);
                int rotate = AndroidUtils.getRotateValue(file.getAbsolutePath());
                if (rotate != 0) {
                    Debug.print("Profile pic rotation value is not 0.");
                    /****** Image rotation ****/
                    Matrix matrix = new Matrix();
                    matrix.postRotate(rotate);
                    bm = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);
                }
                picUri = getImageUri(getApplicationContext(), bm);
                performCropAction();
            } else {
                Tools.showToast(EditProfileActivity.this, "Error occurred, please try again.");
            }
        } catch (Exception e) {
            Debug.printException(e);
        }
    }

    private void performCropAction() {
        try {
            Intent cropAction = new Intent("com.android.camera.action.CROP");
            cropAction.setDataAndType(picUri, "image/*");
            cropAction.putExtra("crop", "true");
            cropAction.putExtra("aspectX", 1);
            cropAction.putExtra("aspectY", 1);
            cropAction.putExtra("outputX", AS.getInPixels(100));
            cropAction.putExtra("outputY", AS.getInPixels(100));
            cropAction.putExtra("return-data", true);
            startActivityForResult(cropAction, CAMERA_IAMGE_CROP);
        } 
        catch (ActivityNotFoundException anfe) {
            Toast.makeText(this, "your device doesn't support the crop action!", Toast.LENGTH_SHORT).show();
        }
    }

如您所见, Bundle extras = intent.getExtras(); 这里的intent.getExtras()始终返回NULL.

任何帮助真的很感激!谢谢.

Answer 1

以上android 5.0裁剪功能在onActivityResult中返回URI,因此请相应地使用手机版本处理它.

Bitmap selectedBitmap;
if(Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Bundle extras = data.getExtras();
selectedBitmap = extras.getParcelable("data");
}
else{
Uri uri = data.getData(); 
selectedBitmap=MediaStore.Images.Media.getBitmap(this.getContentResolver(),uri);
}

希望这可以帮助!

我有同样的问题。新的 CROP 操作不使用 onActivityResult() 方法。解决方案：将文件复制到要保存裁剪图像的文件夹，使用之前复制的文件启动“com.android.camera.action.CROP”。当用户在裁剪后单击“保存”按钮时 - 新复制的文件将被裁剪后的图像替换。如果您有任何疑问，请询问我。
