java.lang.ClassCastException: android.os.BinderProxy cannot be cast to LocalBinder
This question is a few years old and the accepted answer didn't work for me. Perhaps something has changed in the Android environment since the question was asked and answered.
But I stumbled on a simple solution that worked. I saw another question on SO that was trying to start 2 services and they had a similar error (Getting java.lang.ClassCastException: android.os.BinderProxy every time i declare and run two services). One of the answers (@Coeffect) mentioned that the 2 services don't necessarily run in the same process.
I got to thinking that it is possible (probable?) that in my case the activity and the service were run in different processes. So I added the android:process
element to both my activity and my server, and that fixed it.
Here's an example AndroidManifest.xml. Note that both the <activity>
and <service>
tags include android:process=":location"
:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.byteslinger.locationservice">
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<application
android:process=":location"
android:allowBackup="true"
android:icon="@mipmap/icon"
android:label="@string/app_name"
android:roundIcon="@mipmap/icon"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity"
android:process=":location"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:process=":location"
android:name=".LocationService"
android:enabled="true" />
</application>
</manifest>
You've got it flipped:
public void onServiceConnected(ComponentName name, IBinder service) {
LocalBinder binder = (LocalBinder) service;
service = (IBinder) binder.getService();
...
}
should be:
public void onServiceConnected(ComponentName name, IBinder service) {
LocalBinder binder = (LocalBinder) service;
MainActivity.this.service = (ConnectionService) binder.getService();
...
}
