I know this question has been asked time and time again, but it hasn't been answered and I have searched for hours trying to figure this out but the app I am working on integrates google maps. It utilizes the Side Navigation Drawer that slides out and you can select fragments that then switch the view. That being said I have all libraries necessary installed for this app to function, it compiles and builds correctly but whenever I click on the fragment that houses the app, it crashes. So here are my files.
MainActivity.java -
package com.raziel.android.publictoilet;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.widget.DrawerLayout;

*/
private CharSequence mTitle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
@Override
public void onNavigationDrawerItemSelected(int position) {
//Switches the Fragmentx.java
Fragment fragment;
switch (position){
case 1:
fragment = FirstFragment.newInstance(position + 1);
break;
case 2:
fragment = SecondFragment.newInstance(position + 1);
break;
case 3:
fragment = ThirdFragment.newInstance(position + 1);
break;
}
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
.commit();
}
public void onSectionAttached(int number) {
switch (number) {
case 1:
mTitle = getString(R.string.title_section1);
break;
case 2:
mTitle = getString(R.string.title_section2);
break;
case 3:
mTitle = getString(R.string.title_section3);
break;
case 4:
mTitle = getString(R.string.title_section4);
break;
}
}
public void restoreActionBar() {
ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle(mTitle);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (!mNavigationDrawerFragment.isDrawerOpen()) {
// Only show items in the action bar relevant to this screen
// if the drawer is not showing. Otherwise, let the drawer
// decide what to show in the action bar.
getMenuInflater().inflate(R.menu.main, menu);
restoreActionBar();
return true;
}
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
/**
* The fragment argument representing the section number for this

*/
private static final String ARG_SECTION_NUMBER = "section_number";
/**

public static PlaceholderFragment newInstance(int sectionNumber) {

map.java - This is holds the acutal "map code" that's because with the side layout under the MainActivity extends ActionBarActivity...NavigationDrawerCallbacks it cannot implement two different callback functions. package com.raziel.android.publictoilet;
import android.app.Activity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class map extends Activity implements OnMapReadyCallback {
// Used to call the map and inflate fragment in container
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.the_map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap map) {
LatLng sydney = new LatLng(-33.867, 151.206);
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));
map.addMarker(new MarkerOptions()
.title("Sydney")
.snippet("The most populous city in Australia.")
.position(sydney));
}
}
Now there are sections on the side. All with labels and such the one that holds the map is named map.xml -
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity$PlaceholderFragment">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/the_map"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
Here is my AndroidManifest.xml file. This contains all the necessary parts that might be needed for my map app such as my API_KEY which is included.
AndroidManifest.xml -
<?xml version="1.0" encoding="utf-8"?>

</application>
The logcat shows that it is caused by:
Caused by: java.lang.RuntimeException: API key not found. Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml
But the thing is I cannot change the AndroidManifest.xml file to fix this issue because it auto-regenerates every build! And as you can clearly see it is in the AndroidManifest.xml. I have tried making it read-only but then it just compiles forever not throwing any errors. Can anyone please help. Again this is in Android Studio.
Nevermind I fixed it. The app was generating a AndroidManifest.xml file and I was trying to edit that. That was the wrong one. The correct one is located in app/src/main and I added my key to that. Thanks to the guy that down voted me, real helpful.
