Question

I had a Android APP with activity and everything. however, I am trying to turn it into library and use it in another app. the APP compiled as a JAR file just fine.

however, when I call an activity from jar file , it immediately fails with ClassNotFound exception.

this is how I am calling the intent:

    Intent dialerIntent = new Intent(this, SipHome.class);
    startActivity(dialerIntent);

here SipHome.class is defined in the library jar file.

The error that I get is:

05-23 17:23:36.081: E/AndroidRuntime(21634): java.lang.RuntimeException: Unable to get provider com.thaifi.remote.db.DBProvider: java.lang.ClassNotFoundException: com.thaifi.remote.db.DBProvider in loader dalvik.system.PathClassLoader[/data/app/com.thaifi.remote-2.apk]

any idea what might be the issue?

here is my manifest.xml for the jar file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.csipsimple"
    android:versionCode="1485"
    android:versionName="0.04-00" >

    <uses-sdk
        android:minSdkVersion="4"
        android:targetSdkVersion="15" />

</manifest>

Answer 1

this is simple as i found out.

simply declare the activity in manifest (even though the class for that activity is in another jar file) and call it like you would call any other activity.
