Как устранить ошибку синтаксического анализа пакета при установке файла apk в Android Nougat

Question

Я работаю над установкой APK файла, присутствующего в устройстве программно.Вот мой код.

public class MainActivity extends AppCompatActivity {

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

        askForPermission(Manifest.permission.READ_EXTERNAL_STORAGE,0x4);
        askForPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE,0x3);

        Button button = findViewById(R.id.install);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                Intent intent = new Intent();
                Uri photoURI = FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID + ".provider", new File(Environment.getExternalStorageDirectory()+"/ExtractedApks/Airtel_TV_tv.accedo.airtel.wynk.apk"));
                //Uri photoURI = FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID + ".provider", new File(Environment.getExternalStorageDirectory()+"/Download/Airtel_TV_tv.accedo.airtel.wynk.apk"));
                intent.setDataAndType(photoURI, "application/vnd.android.package-archive");
                intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                startActivity(intent);



            }
        });

    }

    private void askForPermission(String permission, Integer requestCode) {
        if (ContextCompat.checkSelfPermission(MainActivity.this, permission) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, permission)) {
                ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);
            } else {
                ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);
            }
        } else {
            return;
            //Toast.makeText(this, "" + permission + " is already granted.", Toast.LENGTH_SHORT).show();
        }
    }


}


**MainActivity** - create a button to install apk file store in external memory.
