    text
    copied!<p>I have a Broadcast receiver setup so that a pop-up message is displayed to the user after each upgrade of my app, or if this is the first time the package is installed. I tested this on my Droid running Android 2.2 both as a fresh install and after upgrading my app, as well in the Emulator running 1.5 and 1.6, and I see everything run fine.</p> <p>However, I received an error report from a user that lists the following exception:</p> <pre><code>java.lang.RuntimeException: Unable to instantiate receiver com.name.pkg.FirstRunBroadcastReceiver: java.lang.ClassNotFoundException: com.name.pkg.app_name.FirstRunBroadcastReceiver in loader dalvik.system.PathClassLoader[/data/app/com.name.pkg.app_name.apk] at android.app.ActivityThread.handleReceiver(ActivityThread.java:2789) at android.app.ActivityThread.access$3200(ActivityThread.java:125) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2083) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4627) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.ClassNotFoundException: com.name.pkg.app_name.FirstRunBroadcastReceiver in loader dalvik.system.PathClassLoader[/data/app/com.name.pkg.app_name.apk] at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:243) at java.lang.ClassLoader.loadClass(ClassLoader.java:573) at java.lang.ClassLoader.loadClass(ClassLoader.java:532) at android.app.ActivityThread.handleReceiver(ActivityThread.java:2780) ... 10 more </code></pre> <p>Can someone tell me why one of my users received this exception?</p> <p>In my Manifest file, I have things setup like this:</p> <pre><code>&lt;receiver android:name=".FirstRunBroadcastReceiver"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.PACKAGE_REPLACE"/&gt; &lt;data android:scheme="package" android:path="com.name.pkg.app_name"&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; </code></pre> <p>The class FirstRunBroadcastReceiver is setup like this:</p> <pre><code>package com.name.pkg.app_name; public class FirstRunBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Contenxt context, Intent intent) { Uri uri = intent.getData(); if( uri.toString().compareTo("package:com.name.pkg.app_name") == 0 ) { //set shared prefs data to determine if start-up message should be shown } } } </code></pre> <p>Upon a first time install, the default value for the shared prefs is set so that the pop-up message will be displayed, but I wouldn't think that would have anything to do with this exception.</p> <p>I tested it again, and I don't receive an exception. Thanks for any help you can provide.</p>
