I will post code here.
I have developed a simple app using AIDE on my phone as opposed to Android Studio on PC. It is part of an Udemy course.
It keeps crashing when I click to run on AIDE.
When I click to run a pop up appears saying "This app may be harmful and may damage your device and data. We do not recommend you install this app"
I clicked to Install.
Moments later the app shuts down before anything appears with the message "Unfortunately MyApp had to be stopped".
Are there any problems with the code. I will post all java, XML and manifest code below.

The main java code
package com.mycompany.myapp;
import android.app.*;
import android.os.*;
import android.graphics.*;
import android.widget.*;
import android.view.View.*;
public class MainActivity extends Activity
{
TextView tipTotalTextView;
TextView totalTextView;
EditText billTotalEditView;
Button TenPercentButton;
Button FifteenPercentButton;
Button TwentyPercentButton;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getWindow().getDecorView().setBackgroundColor(Color.BLUE);
tipTotalTextView = (TextView)findViewById(R.id.TipTotal);
totalTextView = (TextView)findViewById(R.id.Total);
billTotalEditView = (EditText)findViewById(R.id.BillTotal);
TenPercentButton = (Button)findViewById(R.id.Percent10);
FifteenPercentButton = (Button)findViewById(R.id.Percent15);
TwentyPercentButton = (Button)findViewById(R.id.Percent20);
TenPercentButton.setOnClickListener(new android.view.View.OnClickListener(){
public void onClick(android.view.View v){
Double TotalOfBill = Double.valueOf(billTotalEditView.getText().toString());
Double TotalTip = TotalOfBill * 0.1;
tipTotalTextView.setText("Tip: $"+TotalTip.toString());
Double total = TotalOfBill + TotalTip;
totalTextView.setText("Tip: $"+total.toString());
}
});
FifteenPercentButton.setOnClickListener(new android.view.View.OnClickListener(){
public void onClick(android.view.View v){
Double TotalOfBill = Double.valueOf(billTotalEditView.getText().toString());
Double TotalTip = TotalOfBill * 0.15;
tipTotalTextView.setText("Tip: $"+TotalTip.toString());
Double total = TotalOfBill + TotalTip;
totalTextView.setText("Tip: $"+total.toString());
}
});
TwentyPercentButton.setOnClickListener(new android.view.View.OnClickListener(){
public void onClick(android.view.View v){
Double TotalOfBill = Double.valueOf(billTotalEditView.getText().toString());
Double TotalTip = TotalOfBill * 0.2;
tipTotalTextView.setText("Tip: $"+TotalTip.toString());
Double total = TotalOfBill + TotalTip;
totalTextView.setText("Tip: $"+total.toString());
}
});
}
}
And the manifest code
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mycompany.myapp" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:resizeableActivity = "true">
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
When I click to run a pop up appears saying "This app may be harmful and may damage your device and data. We do not recommend you install this app"
I clicked to Install.
