I wrote an App which has a Launcher activity and two Map activities.
When I run it, one Map activity works like a dream, while the other crashes with a java.lang.NoClassDefFoundError. The one that crashes has a "Link of class failed" warning before I invoke it.
I have been through all the applicable solutions on SO and none seem to help.I have:
checked and rechecked the Android Manifest,
done all that was advised to do to the Java Build Path.
checked all the imports of the activity (that crashes) to see that they were not implemented after the android:minSdkVersion in the Manifest
Since my App uses com.google.android.maps.* classes I considered putting a
<uses-library android:name="com.google.android.maps" />
element in the Manifest, but that produced an
Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
which according to Commonsware, Mar 27 '14:
< You have a element in your manifest. Either
that should not be there, or
you are attempting to install the app on a device that does not have that library. >
I tried inserting the maps.jar into my device's folders manually but that didn't get rid of the error either.
So here is my code: Launcher Activity class (called Selector.class):
package com.thenewboston.googlemaps;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Selector extends Activity implements View.OnClickListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.select_activity);
Button bMain = (Button)findViewById(R.id.button1);
Button bOther = (Button)findViewById(R.id.button2);
bMain.setOnClickListener(this);
bOther.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.button1:
Intent main_intent = new Intent(this,MainActivity.class);
startActivity(main_intent);
break;
case R.id.button2:
Intent other_intent = new Intent(this,OtherActivity.class);
startActivity(other_intent);
break;
}
}
}
My 2nd Map Activity called OtherActivity.class (which crashes):

Any ideas about what to do?
