On clicking predict button, the app crashes

Recently I have been working on android studio, I built a python image classification model and want to integrate it with an app. But when I click on predict button, the app crashes. Would be helpful if I can get the idea as to where things are going wrong.
Attached is the code and the error it throws -

Need suggestions as to what's going on and how to resolve it. I'm using android studio arctic fox 2020.3.1 patch 3.

The logcat already told you that it crashed at the setText() call. You called
tv.setText((int) outputFeature0.getFloatArray()[0]);
The int in setText(int) refers to a Resource ID defined in the string.xml (R.string.xxx).
If you are not getting the string from res, you should use setText(CharSequence) instead.
You probably want
tv.setText(String.format("%f",outputFeature0.getFloatArray()[0]));
(change "%f" to any decimal points or format you want)

TextWatcher shuts down my application after starting up

My app keeps crashing since I started using a TextWatcher...
As you can see below i made a TextWatcher to 3 EditText fields...
And i made a button which listens to the 3 EditText..
If they are empty the button become disabled.
When the fields are filled the button should become enabled..

There are two findViewById(R.id.knop);
remove this line:
knop = findViewById(R.id.knop);
and change :
knopconfirm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, (R.string.succes), Toast.LENGTH_SHORT) .show();
}
});

You are saying your app is crashing since you started using TextWatcher. So why don't you stop using it?
you can achieve the same thing without using TextWatcher by doing this.
knop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String registernummerinput = EditTextregisternummerbalk.getText().toString().trim();
String ticketnummerinput = EditTextticketnummerbalk.getText().toString().trim();
String artikelnummerinput = EditTextartikelnummerbalk.getText().toString().trim();
if((!registernummerinput.isEmpty() && !ticketnummerinput.isEmpty() &&! artikelnummerinput.isEmpty())) {
Toast.makeText(MainActivity.this, (R.string.succes), Toast.LENGTH_SHORT) .show();
}
}
});
you will not need any TextWathcer just modify the listner

I'm try to play a loading animation on my loading screen, and I read somewhere that android doesn't support gifs so either you have to break in into frames and then play it or we can use the Movie class.

In the above code I've set content view by passing it an instance of MYGIFView.class -
Heres MYGIFView.class

import android.graphics.Color;
import android.graphics.Movie;
import android.view.View;

public class MYGIFView extends View{
Movie movie,movie1;
InputStream is=null,is1=null;
long moviestart;
public MYGIFView(Context context) {
super(context);
is=context.getResources().openRawResource(+ R.drawable.loading);
movie=Movie.decodeStream(is);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
super.onDraw(canvas);
long now=android.os.SystemClock.uptimeMillis();
System.out.println("now="+now);
if (moviestart == 0) { // first time
moviestart = now;
}
System.out.println("\tmoviestart="+moviestart);
int relTime = (int)((now - moviestart) % movie.duration()) ;
System.out.println("time="+relTime+"\treltime="+movie.duration());
movie.setTime(relTime);
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
this.invalidate();
}
}
The loading activity IS creating an instance of MYGIFView.class and it logs the data but then it gives fatal signal 11. I tried to search but I didn't get any answer.

I received a batch for this question which means its being viewed a lot, so I'll answer this question -
What I figured out was the line below was throwing the error -
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
Now the problem is that this error specifically can be caused by lots of reasons, its never a specific reason.. the reason mine wasn't working out was because my device didn't work well with hardware acceleration, so I just had to disable it in the manifest application, like this -
<android:hardwareAccelerated="false">
Now its possible that the reason might not be the same....but the core reason is the same, its memory related, and most chances are its a bug in the firmware of the device or emulator you are testing upon.

In the Manifest set in your activity :
<activity
android:name="LoadingScreen"
android:hardwareAccelerated="false">
</activity>

I got here with the exact same problem but in React Native, so I will put a solution for those who need it too. The error may be triggered by react-native-webview and/or React Navigation. In some cases, like me, you don't want to disable Hardware Acceleration on the whole app, so here's a workaround:
react-native-webview
<WebView
androidHardwareAccelerationDisabled
source={source}
/>
React Navigation 5
<NavigationContainer>
<Stack.Navigator initialRouteName="HomeScreen">
<Stack.Screen
name="HomeScreen"
component={HomeScreen}
options={{
animationEnabled: false,
}}
/>
</Stack.Navigator>
</NavigationContainer>

Error while opening Android app

i am new to android development and i am writing an app for my college project .The app transmits a string of data stored in shared preferences .The data is stored by one time setup screen which is never shown again.The issue is after first time,when app is started again it shows that "app has unfortunately stopped working "and when i click ok the app starts.Can anybody tell me why this is happening?
Code:
package com.example.homeautomation.zigbeehomeauto;
import android.annotation.TargetApi;
import android.content.SharedPreferences;
import android.nfc.NdefMessage;
import android.nfc.NdefRecord;
import android.nfc.NfcAdapter;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Toast;
public class MainScreen extends ActionBarActivity {
NdefMessage msg;
NfcAdapter nfcadapter;
public static final String PREFS_NAME = "MyPrefsFile";
public String pass2 ;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
SharedPreferences check = getSharedPreferences(PREFS_NAME, 0);
String Pass = check.getString("Str", "Nothing");
pass2 = Pass;
nfcadapter = NfcAdapter.getDefaultAdapter(this);
if (nfcadapter == null) {
Toast.makeText(this, "NFC is not available User", Toast.LENGTH_LONG)
.show();
finish();
}
}
public void ExApp(View v) {
finish();
System.exit(0);
}
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void Nsend(View v)
{
byte[] stringBytes = pass2.getBytes();
nfcadapter.setNdefPushMessage(msg = new NdefMessage(new NdefRecord[]{NdefRecord.createMime("text/plain", stringBytes)
}),this);
}
}

Check in your SetupScreen.java do you have super.onCreate(savedInstanceState);
after onCreate() Method is starts .
post your SetupScreen.java code also ..

Your onCreate() method of class SetupScreen do not call the super.onCreate(). Add the statement and the error should go away.
