Access React Application Context from Android Application #14916
Description
Is this a bug report?
Yes?
Have you read the Bugs section of the Contributing to React Native Guide?
yes
Environment
react-native-cli: 2.0.1
react-native: 0.44.2
v7.10.0
5.1.0
Android
macOS
Android Studio
Steps to Reproduce
Create a Native Module to save data:
FileOutputStream fos = getReactApplicationContext().openFileOutput(MainApplication.SOME_DATA_FILE, Context.MODE_PRIVATE);
I'm trying to provide a static method to retrieve the data inside SOME_DATA_FILE
Expected Behavior
I don't know if it's possible to cast ApplicationContext to ReactApplicationContext
...Module(ReactApplicationContext reactContext) { ...
Actual Behavior
Since getReactApplicationContext is not static, I have to instantiate the Module.
Naively doing so from Android code gives me an error:
(casting etc, does not work)
DataModule dm = new DataModule((ReactApplicationContext) getApplicationContext());
dm.getData();
