AIDE (Android IDE)：如何导入 FileProvider 类？

如何解决AIDE (Android IDE)：如何导入 FileProvider 类？

我正在尝试拍照以在我的应用中显示它。我正在关注 developer.android.com 上名为 Take Pictures 的 Android 教程。我遇到的问题是，如果类和导入没有下划线，我就无法为 FileProvider 添加导入。

我正在使用 AIDE (Android idE) 应用在 Android 10 手机上开发此应用程序，这给了我错误。

知道如何解决这个问题，以及如何让它在 AIDE 上运行吗？

谢谢。

这是我的 MainActivity.java：

package com.me.foo;

import android.app.*;
import android.content.*;
import android.graphics.*;
import android.net.*;
import android.os.*;
import android.provider.*;
import android.widget.*;
import java.io.*;
import java.text.*;
import java.util.*;

import androidx.core.content.FileProvider;

public class MainActivity extends Activity 
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        dispatchTakePictureIntent();
    }
    // request codes
    
    static final int REQUEST_IMAGE_CAPTURE = 1;
/*
    private void dispatchTakePictureIntent() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        try {
            startActivityForResult(takePictureIntent,REQUEST_IMAGE_CAPTURE);
        } catch (ActivityNotFoundException e) {
            // display error state to the user
        }
    }
*/
    @Override
    protected void onActivityResult(int requestCode,int resultCode,Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            ImageView picImageView = findViewById(R.id.picImageView);
            picImageView.setimageBitmap(imageBitmap);
        }
    }
    
    String currentPhotoPath;

    private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_" + timeStamp + "_";
        File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(
            imageFileName,/* prefix */
            ".jpg",/* suffix */
            storageDir      /* directory */
        );

        // Save a file: path for use with ACTION_VIEW intents
        currentPhotoPath = image.getAbsolutePath();
        return image;
    }
    
    private void dispatchTakePictureIntent() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        // Ensure that there's a camera activity to handle the intent
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            // Create the File where the photo should go
            File photoFile = null;
            try {
                photoFile = createImageFile();
            } catch (IOException ex) {
                // Error occurred while creating the File
                //...
            }
            // Continue only if the File was successfully created
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this,"com.example.android.fileprovider",photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,photoURI);
                startActivityForResult(takePictureIntent,REQUEST_IMAGE_CAPTURE);
            }
        }
    }
