writeFile faild with no error

I'm using redux-persist-fs-storage which use react-native-fs as it's persist storage, I have tried to save some settings for my app but failed. After debug, I found the problem was caused by this block `https://github.com/itinance/react-native-fs/blob/master/android/src/main/java/com/rnfs/RNFSManager.java#L128-L130` of code, it will be success without error, but the file not exists actually.

```
filepath = "/data/user/0/com.myapp/files/persist/111";
```

My environments:
react-native: 0.52.3
react-native-fs: 2.9.11
Android: 7.1.1
