如何将文件从资产复制到特定游戏的“ / data / data”文件夹？

Question

我拥有的代码运行正常，但是文件未复制到游戏所在的“ / data / data / game”根文件夹中。实际上，它已复制到“ / storage / emulated / 0” 请帮助我，我要复制的文件是一个简单的.json文件，它仅更改文本，甚至不修改值，等等。

package com.example.myapp;

public class MainActivity extends AppCompatActivity {

    private static final int MY_PERMISSION_RQUEST_STORAGE = 1;

    Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //give the app permission to access storage
        if (ContextCompat.checkSelfPermission(MainActivity.this,

                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    if (ContextCompat.checkSelfPermission(MainActivity.this,
                            Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                        //do nothing
                    }
                } else {
                    Toast.makeText(this, "No permission granted!", Toast.LENGTH_SHORT).show();
                }
            }
        }
    }

    private void copyAsset(String filename) {
        String dirPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "//data/data/game";
        File dir = new File(dirPath);
        if (!dir.exists()) {
            dir.mkdirs();
        }
        AssetManager assetManager = getAssets();
        InputStream in = null;
        OutputStream out = null;
        try {
            in = assetManager.open(filename);
            File outfile = new File(dirPath, filename);
            out = new FileOutputStream(outfile);
            copyFile(in, out);
            Toast.makeText(this, "¡Parchado!", Toast.LENGTH_SHORT).show();
        } catch (IOException e) {
            e.printStackTrace();
            Toast.makeText(this, "¡Error!", Toast.LENGTH_SHORT).show();
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    private void copyFile(InputStream in, OutputStream out) throws IOException {
        byte[] buffer = new byte[1024];
        int read;
        while ((read = in.read(buffer)) != -1) {
            out.write(buffer, 0, read);
        }
    }
}

没有错误（表示我的应用正在运行），我只希望将其复制到“数据/数据/游戏”中
