Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.LocalBroadcastManager"

This error message indicates that the application is trying to use the LocalBroadcastManager class from the Android Support Library, but the class is not present in the application's classpath.

To solve this issue, you can try the following steps:

1. Make sure that you have added the Android Support Library to your project's dependencies. You can do this by adding the following line to your app's build.gradle file:

implementation 'com.android.support:support-v4:28.0.0'

2. If you have already added the Android Support Library, try cleaning and rebuilding your project. Sometimes, the build process can fail to update the classpath, which can cause this error.

3. If the above steps do not work, try updating the Android Support Library to the latest version. You can do this by changing the version number in the implementation statement in your build.gradle file:

implementation 'com.android.support:support-v4:28.0.0' -> implementation 'com.android.support:support-v4:28.0.0-alpha1'

4. If none of the above steps work, try adding the following line to your app's build.gradle file:

android {
...
useLibrary 'org.apache.http.legacy'
...
}

This will enable the use of the deprecated Apache HTTP client library, which may be required by some older versions of the Android Support Library.
