SO users, please read fully then decide to mark the Duplicate for NullPointer exception.
While app launch, from ApplicationExt(extends Application), we initialize the thread in which load the CSV file from Resource bundle(RawSource). It always works on many of the devices. But get crashed on below device for the very first time. For the second time, it gets loaded from the bundle.

MIUI13+Android12
The RemoteException error is reported on line 553 of MediaProjectionManagerService. After checking the source code, the error message is that the package for applying for mediaprojection cannot be found.
It is guessed that MIUI maintains a separate list for this, only the package that has applied for permission will be in it, and it will be removed after obtaining and closing mediaprojection. No such mechanism has been seen in other systems.
In other words, intent data cannot be reused. The solution is also very simple, just don’t close the mediaprojection after using it.
I have a form that I open in a webview in my app, after I complete it, it will appear a button that will let me download a pdf andd open it but when I do this I keep getting the next error:

The button will appear in the webview. I think I get that error because I open the pdf on the main thread.
I'm trying to get my MongoDB database linked to my front react-native app, and I can't get rid of this error message when I run the app with Expo: "Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference".
I think my error occurs in the 'then function' right after my axios request:
getConnected = () => {
console.log('still ok');
axios.get(`api/signin/${this.state.email}/${this.state.password}`)
.then(function(res) {
console.log('Fetching data');
}.bind(this))
.catch(error => {
console.log(error.res);
});
}
I've created a proxy in the package.json in order to link the database to the app, I'm not sure this is the right way to do it. I'm a beginner!
Can someone help me figure out what I'm doing wrong here?
Let me know if you need further details.
Thanks!

I've just had this problem a minute ago. It seems if the URL is invalid, you will get this error.
For my folder set up I had something like app.js and a folder called api, with a file called api.json. You cannot fetch the folder from here like you would with a html application. For example
fetch("./api/api.json")
The above would return the error you are getting.
You need to use the Assets system.

I'm getting a crash on our app on a part that used to work:
a call to Capture.captureAudio() to get the path to a newly recorded audio file.
I've tested on android and I get this stack trace:

It has been a while since this part of the app was throughly tested, and I'm not entirly sure which version of CN1 this was working on.
Capture.capturePhoto() and Capture.captureVideo() are both still working as expected.
This should be fixed in current versions of the Android build
I know some of exceptions are thrown by Android framework. Like ActivityNotFoundException, WindowManager.BadTokenException.
