running into an interesting one with ReactNative.
On the Android side, anywhere in my app, when a modal is open, if the user does a Long Press on the Home Button, then the app crashes.
It's fine for a single tap, and it doesn't have issues when the screen is not a Modal. iOS does not have any issues.
On a semi-related note, if we use the touchid, and a fingerprint is registered, the app does not crash, and the user is signed in. This tells me there should be an event I can catch to deal with this... but I don't know what that event may be.
The modal is very basic (I have removed styles for clarity, however they are all added like this <View style = {styles.modalStyle}>
Modal:
<Modal
onRequestClose={()=> {
props.waitingForResponse(false);
}}
visible={props.visible}>
<View>
<View>
<View>
<Image source={modalImageSrc} />
<Text>
{props.showErrorMesage ? "Error" : props.title}
</Text>
<Text>{props.showErrorMesage ? "Item disabled" : props.text}</Text>
</View>
<View>
<Button
onPress={()=> {
props.waitingForResponse(false);
}}
title="Cancel"
/>
</View>
</View>
</View>
</Modal>
All Modals are created in a similar fashion.
As of this point, I thought I could add something directly to the Modal itself - an onError or onPause (nope, those events don't exist for Modals?!?)... I can't seem to "catch" the long hold home press in this environment So now, I am trying to override some functions on the Java side - in MainActivity.java, I tried an Override of the onKeyUp, onKeyDown, onKeyLongPress - but none of these are currently triggered on the long-press of KeyEvent.KEYCODE_HOME. (See below)
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if( keyCode == KeyEvent.KEYCODE_HOME){
Toast.makeText(MainActivity.this, "onKeyDown KeyEvent.KEYCODE_HOME", Toast.LENGTH_LONG).show();
event.startTracking();
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if( keyCode == KeyEvent.KEYCODE_HOME){
Toast.makeText(MainActivity.this, "onKeyUp KeyEvent.KEYCODE_HOME", Toast.LENGTH_LONG).show();
return true;
}
return super.onKeyUp(keyCode, event);
}
@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if( keyCode == KeyEvent.KEYCODE_HOME){
Toast.makeText(MainActivity.this, "onKeyLongPress KeyEvent.KEYCODE_HOME", Toast.LENGTH_LONG).show();
return true;
}
return super.onKeyLongPress(keyCode, event);
}
But I don't seem to be finding any joy.
Has anyone come across this? Any recommendations on where else I could look? Switching to a 3rd party isn't an option at this point, but may be in the future if we can't get this resolved.
Thanks!!
