Question

我想通过相机对图像进行cpature，然后将其上传到firebase中。相机工作正常。但不幸的是应用已经停止.. 我也允许上网和相机。但异常仍然存在...... 这是我的onActivityResult方法......

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK){

        vProgress.setMessage("Uploading Image...");
        vProgress.show();

        Uri uri = data.getData();

        StorageReference filePath = dataReference.child("ProFilePics").child(uri.getLastPathSegment());

        filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                vProgress.dismiss();

                Toast.makeText(rentCarActivity.this, "uploaded...." , Toast.LENGTH_LONG).show();
            }
        });
    }
}

这是我的例外..请有人告诉我什么是布莱恩..

Answer 1

您需要明确要求获取读取外部存储空间的权限。只需添加这些方法并在尝试访问文件存储之前调用它们，它应该可以工作：

private static final int REQUEST_PERMISSION = 1;

private void requestReadFilePermission(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
                && ContextCompat.checkSelfPermission(mView.getContext(), Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, REQUEST_PERMISSION);
        } else {
            //permission is already granted - do what you need
        }
    }

    @Override
    public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == REQUEST_PERMISSION) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //user granted permission - do what you need
            } else {
                Toast.makeText(mView.getContext(), "Need permission to read storage!", Toast.LENGTH_LONG).show();
            }
        }
    }

当然，您的AndroidManifest.xml文件中已声明<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

Answer 2

你需要要求

android.permission.READ_EXTERNAL_STORAGE

通过运行时权限并在android 6.0及更高版本的清单中声明。在此之下，您可以在清单中声明该权限
