如何获得在/data/data/app_name/lib/abc.so文件夹中重写的权限以添加额外的.so文件

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE);
}

try {
    InputStream inputStream = getAssets().open("extra.so");
    FileOutputStream outputStream = new FileOutputStream("/data/data/app_name/lib/extra.so");
    byte[] buffer = new byte[1024];
    int length;
    while ((length = inputStream.read(buffer)) > 0) {
        outputStream.write(buffer, 0, length);
    }
    outputStream.flush();
    outputStream.close();
    inputStream.close();
} catch (IOException e) {
    e.printStackTrace();
}
