Why do I get ClassCastException?… here is a solution to the problem.
Why do I get ClassCastException?
I came across ClassCastException
while running this simple application.
It was my first attempt at AlarmManager
.
public class AlarmReciever extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
String message = bundle.getString("alarm_message");
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
Here is my list :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tcs.mine"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=". AlarmReciever"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:process=":remote" android:name=". AlarmReceiver"></receiver>
</application>
</manifest>
What am I doing wrong?
Solution
AlarmReceiver
is not an activity
but is declared as one. See the documentation on BroadcastReceiver
how to declare them in the manifest file this tutorial
