had alread cleaned my project and rebuilt the path... I think that the problem is in this part "/data/app/com.rafael.acordenoponto-2.apk", but i don't know how to solve... i think the problem is there because my apk does not have that "-2" in the end... anyone know how to solve?

Here's the manifest:

<receiver android:name=".MonitoraGPS">
    <intent-filter >
        <action android:name="MONITORAR"/>
        <category android:name="android.intent.category.DEFAULT" />     
    </intent-filter>
</receiver>

Answer 1

solved!

the problem happened because .MonitoraGPS was in a different package... so i just added the package name before .MonitoraGPS in the manifest and it worked!

Answer 2

It's no that.

1. Make sure your package-name is correct in anywhere (the java files, the xml files, AndroidManifest files...).
2. Right click on the project; goto Build Path --> Configure Build Path --> Java Build Path --> Order and Export. Then uncheck Android Dependencies and check all third-party .jar, if you have any.
