Quick Fix: Modify code in Bridge.java file: Comment out settings.setAppCacheEnabled(false); and add settings.setCacheMode(WebSettings.LOAD_DEFAULT);.

The Problem:

After upgrading the Android SDK version from 32 to 33 in an Ionic/Angular application with Capacitor, the build fails due to the removal of the "setAppCacheEnabled" method in the WebSettings class.

The Solutions:

Solution 1: Modify Bridge.java file

To resolve this issue, navigate to the ***Bridge.java*** file in your project and make the following changes:

  1. Locate the line `settings.setAppCacheEnabled(false);` and comment it out with `//`. This line is no longer valid since the method `setAppCacheEnabled()` has been removed.
  2. After commenting out the previous line, add a new line below it: `settings.setCacheMode(WebSettings.LOAD_DEFAULT);`.

With these changes, the `Bridge.java` file should look like this:

...
// settings.setAppCacheEnabled(false);
settings.setCacheMode(WebSettings.LOAD_DEFAULT);
...

These modifications will ensure compatibility with the updated Android SDK version 33 and resolve the error related to the missing `setAppCacheEnabled()` method.

Solution 2: Manual Removal

If you are unable to update to Capacitor v5, you can manually remove the line containing `setAppCacheEnabled(boolean)` from the source code. Here’s how you can do it:

  1. Navigate to the following directory in your project:
node_modules/@capacitor/android/capacitor/src/main/java/com/getcapacitor/
  1. Open the Bridge.java file.

  2. Locate the following line:

settings.setAppCacheEnabled(true);
  1. Delete this line.

  2. Save the changes to the file.

After completing these steps, the error should be resolved, and you should be able to build the APK successfully.
