android程序中报病毒的错误

我在Play store 中加载了一个程序,有评论说有一个病毒,有时候强行关闭电话后自己会重新启动。应用程序的代码非常简单:只有一个activity ,还有几个spots,要么能听到,要么设置为铃声。
程序中的代码:

b1_2.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
    if(saveas(soundid,save_name)){
      Toast.makeText(Main.this, "The sound was set as ringtone!",
        Toast.LENGTH_LONG).show();
    };
  }
});
public boolean saveas(int ressound,String filename){
  byte[] buffer=null;
  InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
  int size=0;
  try {
    size = fIn.available();
    buffer = new byte[size];
    fIn.read(buffer);
    fIn.close();
  } catch (IOException e) {
    // TODO Auto-generated catch block
    return false;
  }
  String path="/sdcard/media/ringtones/";
  boolean exists = (new File(path)).exists();
  if (!exists){new File(path).mkdirs();}
  FileOutputStream save;
  try {
    save = new FileOutputStream(path+filename);
    save.write(buffer);
    save.flush();
    save.close();
  } catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    return false;
    } catch (IOException e) {
      // TODO Auto-generated catch block
      return false;
    }
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
      Uri.parse("file://"+path+filename)));
    File k = new File(path, filename);
    ContentValues values = new ContentValues();
    values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
    values.put(MediaStore.MediaColumns.TITLE, "clip_"+save_name);
    values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
    values.put(MediaStore.Audio.Media.ARTIST, "clip");
    values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
    values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
    values.put(MediaStore.Audio.Media.IS_ALARM, true);
    values.put(MediaStore.Audio.Media.IS_MUSIC, true);
    //Insert it into the database
    Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
    getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" +
      k.getAbsolutePath() + "\"", null);
    Uri newUri= this.getContentResolver().insert(uri, values);
    RingtoneManager.setActualDefaultRingtoneUri(
      this, RingtoneManager.TYPE_RINGTONE, newUri);
    return true;
  }

需要的权限是:

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

没网也能正常运行,但是在google play store 中有一个直接的链接能链到我的开发页面,为避免程序崩溃,我使用下面的代码解决:

(if link is pressed)
  if (isOnline()){
    open page
} else {
  do nothing
}
public boolean isOnline() {
        boolean connectedWifi = false;
        boolean connectedMobile = false;

        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo[] networks = cm.getAllNetworkInfo();
        for (NetworkInfo ni : networks) {
            if ("WIFI".equalsIgnoreCase(ni.getTypeName()))
                if (ni.isConnected())
                    connectedWifi = true;
            if ("MOBILE".equalsIgnoreCase(ni.getTypeName()))
                if (ni.isConnected())
                    connectedMobile = true;
        }
        return connectedWifi || connectedMobile;
    }
