Question

使用“工程图视图”制作工程图，然后将其转换为图像，然后将其保存在数据库中，当活动结束时，应该与之共享选项，并且一旦保存图像就不再显示与之共享的选项。其他应用程序，但重定向到另一个视图。

dv_example = (DrawingView) findViewById(R.id.drawing_view);
saveEditedImage(dv_example.getBitmap());

UseMethod saveEditedImage

private void saveEditedImage(Bitmap bitmap) {
        File file = null;
        try {
            file = createImageFile();
        } catch (IOException e) {
            Log.e("CreateImageFile", "Error after attempting to create the container file for the image.");
            e.printStackTrace();
        }
        try {
            FileOutputStream outputStream = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream); 
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
            Log.e("Crop", "Failed to save");
            return;
        }
        Uri uri = FileProvider.getUriForFile(context, context.
getPackageName() + ".provider", file);
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/jpeg");
        intent.putExtra(Intent.EXTRA_STREAM, uri);
        startActivity(intent);
    }

方法createImageFile（）;

private File createImageFile() throws IOException {
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        imageFileName = "JPEG_" + timeStamp + "_";
        File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(imageFileName, ".jpg", storageDir );

        mCurrentPhotoPath = image.getAbsolutePath();
        Log.i("PATH", mCurrentPhotoPath);
        return image;
    }

清单

<provider
       android:name="androidx.core.content.FileProvider"
       android:authorities="${applicationId}.provider"
       android:grantUriPermissions="true"
       android:exported="false">
       <meta-data
           android:name="android.support.FILE_PROVIDER_PATHS"
           android:resource="@xml/filepaths" />
</provider>

停用，与Android上的其他应用共享吗？
