无法在Android 8和9中从相机和图库上传图片

Question

我的应用程序中有个人资料图片概念。 用户可以选择从应用程序中的相机或图库上传图像，但问题是图像正在上传到某些设备而不是全部。 主要是Android版本8和9出现问题。我几乎尝试了一切但未能实现。 请帮忙。

码：

   dialog = new Dialog(getActivity());
            dialog.setContentView(R.layout.dialog_image_upload);
            dialog.setCanceledOnTouchOutside(false);
            dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

            TextView txtTakePhoto = (TextView) dialog.findViewById(R.id.txtTakePhoto);
            TextView txtPictureFromGallery = (TextView) dialog.findViewById(R.id.txtPictureFromGallery);
            ImageView imgClose = (ImageView) dialog.findViewById(R.id.imgClose);

            imgClose.setOnClickListener(this);
            txtTakePhoto.setOnClickListener(this);
            txtPictureFromGallery.setOnClickListener(this)

从相机拍照的代码：

        case R.id.txtTakePhoto:

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
                    {
                        cameraIntent();
                    }

                } else {
                    if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.CAMERA)) {
                        Toast.makeText(getActivity(), "App requires Phone permission.\nPlease allow that in the device settings.", Toast.LENGTH_LONG).show();
                    }
                    ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CAMERA}, PHONE_PERMISSION_CODE);
                }
            } else {
                cameraIntent();

            }
            break;

从画廊拍照的代码：

        case R.id.txtPictureFromGallery:

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                    {
                        imageBrowse();

                    }

                } else {
                    if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)) {
                        Toast.makeText(getActivity(), "App requires Phone permission.\nPlease allow that in the device settings.", Toast.LENGTH_LONG).show();
                    }
                    ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PHONE_PERMISSION_CODE);
                }
            } else {

                imageBrowse();

            }
            break;

待上传的图片代码：

        private void cameraIntent() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, REQUEST_CAMERA);

        fileAddress = FilePath.getPath(getActivity(), picUri);
        File f3 = new File(fileAddress);
        edtProofOfAddressValue.setText(f3.getName());
        Log.e("tag", "fileAddress" + fileAddress);

    } else if (requestCode == 5 && resultCode == RESULT_OK && data != null && data.getData() != null) {

//

Answer 1

是的，您需要配置FileProvider。 在应用的清单中，向您的应用添加提供商：

<application>
   ...
   <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.example.android.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
    </provider>
    ...
</application>

确保权限字符串与getUriForFile（Context，String，File）的第二个参数匹配。 在提供程序定义的元数据部分中，您可以看到提供程序期望在专用资源文件res / xml / file_paths.xml中配置符合条件的路径。 以下是此特定示例所需的内容：

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" />
</paths>
