When I run below activity, I get an exception. I've wrapped the exception
in an AlertDialog. Here's what the dialog shows.
* null
null
null
java.lang.NullPointerException
*
Where do I even START looking for a problem?
I've commented-out everything I can think of and the exception still
happens.
arrrrrgggghhhh!
I'm a newbie and I'm stumped!
Here's the Activity
AlertDialog marked with "">>"
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class EncDocRetrieve extends Activity {
Button retrieveDoc;
//EditText DocName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
setContentView(R.layout.activity_enc_doc_retrieve);
retrieveDoc = (Button) findViewById(R.id.btnRetrieveDoc);
retrieveDoc.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//DocName = (EditText)
findViewById(R.id.edtextDocUserName);
Intent intent = new
Intent(EncDocRetrieve.this,
DecryptKeyGet.class);
//intent.putExtra(android.content.Intent.EXTRA_TEXT, DocName
// .getText().toString());
startActivity(intent);
}
});
>> } catch (Exception e) {
>> AlertDialog.Builder dialog = new
AlertDialog.Builder(this);
>> dialog.setTitle("Opps Exception");
>> String err = e.getLocalizedMessage() + "\n" +
e.getCause() + "\n" + e.getMessage() + "\n" + e.toString();
>> dialog.setMessage(err);
>> dialog.setNeutralButton("Cool", null);
>> dialog.create().show();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_enc_doc_retrieve,
menu);
return true;
}
}
