Android Map Application has stopped unexpectedly

Question

I am working on an Android Project of using goolge map. But when I try to run it on a tablet or HTC phone, it says the application has stopped unexpectedly. What kind of setting do I need to do, like adding library files and etc.

I have used my API key as well, so if this apps runs on a device, can I view the map or only the grid? what do we mean by signing the app?

MainActivity.java

package com.sulav.maptravis2;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends MapActivity {
MapView map;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    try{
    map=(MapView) findViewById(R.id.mvMain);
    map.setBuiltInZoomControls(true);
    }
    catch(Exception e){}
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}

}

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

    android:id="@+id/mvMain"
    android:apiKey="AIzaSyBxPKfOUpiOK981HFNcXi6szt0Dn__tQko"
    />

</RelativeLayout>

    </activity>

</manifest>

@SulavTimsina it does not look like you are using api v2. pls follow the link @ https://developers.google.com/maps/documentation/android/start — Raghunandan, May 24 '13 at 06:16
looking at your code it seems to me like you are using api v1. have a look at these links to use v2 http://www.vogella.com/articles/AndroidGoogleMaps/article.html and https://developers.google.com/maps/documentation/android/start — prvn, May 24 '13 at 06:26
i have used api v2 but may be my code is for v1 since it is from an old tutorial.how do i change/edit the code so the it works with api v2 @prvn — Sulav Timsina, May 24 '13 at 07:01
There are a lot of things to change follow the links i have given above if you are stuck somewhere let me know i will help you — prvn, May 24 '13 at 07:08

Not sure if you just failed to paste it in but it appears your layout is missing this at the top.

<?xml version="1.0" encoding="utf-8"?>

Regardless check this link out: What is 'android.security.MessageDigest''?

adding that line also doesn't help :( – Sulav Timsina May 24 '13 at 06:23
Ok what are you trying to run this on? – Larry McKenzie May 24 '13 at 06:24
On a HCL Tablet android 4.0.3. it has no GPS – Sulav Timsina May 24 '13 at 06:26
Just curious... Try running your app in an emulator to see if you get the same error. – Larry McKenzie May 24 '13 at 06:28
I am having problem with my emulators(AVDs).recently ,its been some days,they start very slow,or get stuck on the "android" screen. – Sulav Timsina May 24 '13 at 06:31
I edited my answer, it seems that this error is related to your device manufacturer using an old google maps library but you should be able to fix it. – Larry McKenzie May 24 '13 at 06:33
It runs on HTC aria. but it doesn't show tha map.but only the grid with a google logo at the bottom left of the screen(map grid) – Sulav Timsina May 24 '13 at 06:36
The grid has to do with your api key. You have likely created an api key that works with a signed application. You will need one that works with your debug signing key. See here: https://developers.google.com/maps/documentation/android/start#obtaining_an_api_key – Larry McKenzie May 24 '13 at 06:56
so u mean if i don't want to upload it to google play i dont need the api key? how do i get the debug signing key? – Sulav Timsina May 24 '13 at 07:38
No you need the a pi key to make the map display but you need a key based off your production signing key for production and a key based on your development or debug signing key when developing. The link I posted in the above comment explains it. – Larry McKenzie May 24 '13 at 14:16
