Android: ClassNotFoundException

Question

Ich bekomme diesen seltsamen Fehler. Als ich gestern Nacht wieder zur Arbeit kam, war ich mit diesem Fehler konfrontiert. Was ich nicht verstanden habe ist, dass ich nie etwas im Code geändert habe. Es fühlt sich an, als käme es aus heiterem Himmel.

Hinweis: habe ich mit dem gleichen Problem für andere Fragen suchen und ich habe einige finden. Ich habe jedoch alle Hinweise zu diesen Posts befolgt und es hat mir nicht weitergeholfen. Nachdem ich meine ganze Nacht verschwendet hatte, dachte ich, es wäre eine gute Idee, hier zu posten.

Ich bin nicht sicher, welche Teile meines Codes, wenn überhaupt, sollte ich zusammen mit diesem Posten, also werde ich dies aktiv betrachten und gegebenenfalls bearbeiten. Hier

ist die Manifest-Datei:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.thinkinetics.rob"> 
    <uses-feature android:name="android.hardware.type.watch" /> 

    <!-- Required to act as a custom watch face. --> 
    <uses-permission android:name="com.google.android.permission.PROVIDE_BACKGROUND" /> 
    <uses-permission android:name="android.permission.WAKE_LOCK" /> 
    <uses-permission android:name="android.permission.VIBRATE"/> 

    <application

</manifest> 

Danke.

Answer 1

Ich habe das gleiche Problem gerade jetzt. Ich habe die App vom Gerät deinstalliert, das Projekt neu erstellt und dann erneut installiert. Diesmal hatte ich kein Problem und es funktionierte gut.

Es könnte sich um einen zeitweiligen Fehler mit der Sofortstartfunktion im Studio handeln.
