I want to display a part of a OSM but i don't know what's the problem with my code, when I run it, the map didn't display:
No error appear but the map didn't only display! I work with eclipse and the emulator Google API 8!
here is my MainActivity code:
package com.formation.dsmap1;
import org.mapsforge.android.maps.MapActivity;
import org.mapsforge.android.maps.MapView;
import android.annotation.SuppressLint;
//import android.annotation.SuppressLint;
//import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
//import android.os.Environment;
public class MainActivity extends MapActivity {
// #SuppressLint("SdCardPath")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MapView mapView = new MapView(this);
mapView.setClickable(true);
mapView.setBuiltInZoomControls(true);
mapView.setEnabled(true);
// mapView.setMapFile("/sdcard/essai.jpg");
// setContentView(mapView);
mapView.setMapFile(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "essai.osm");
setContentView(mapView);
}
}
and my AndroidManifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Can you help me please?
add this permission to your manifest and will be fine :
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

I'm trying to get a simple map on my app by using Google Map API V2; I followed all the steps to do it but when I launch my app, I only get white page with a Google logo in the left bottom.
If someone can help me with this, it will be great..
This is the XML file:
<fragment 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:id="#+id/map" tools:context=".MapsActivity"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
This is the file Java:
package com.example.ismail.location_test;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
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.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MapsActivity extends FragmentActivity {
private GoogleMap mMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
}
#Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
private void setUpMap() {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}
And finally the Manifest:
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="21" />
<uses-permission android:name="com.example.ismail.location_test.permission.MAPS_RECEIVE"/>

</application>
I don't see anything wrong with your code. The symptom you decribe point to a not valid api key or gps is turned off, or even your are running this is an emulator with no google play installed. Check what google play versions is installed and used under build.gradle. eg:
dependencies {
compile 'com.google.android.gms:play-services:6.5.87'
I suggest you post your debuger log, if it is an api error it will state it there.
I suspect 3 things wrong in your code :
(1) Declare permission before using it :
<permission android:name="com.example.ismail.location_test.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<!-- after declare use this -->
<uses-permission android:name="com.example.ismail.location_test.permission.MAPS_RECEIVE"/>
(2) Missing Declare gms version variable :
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
(3) Missing declare API_KEY :
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaS33yBBDxSDFsdf33BK-7HCasdfSADFfa72wJnKLZvq6A" />
Please check with above 3 suspects first : then if still error is there you can re-confirm steps to enable Google Maps from here

For me it looks like everything is ok but i recive error
Caused by: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />
So i' wondering whats wrong with my androidmanifest file, any ideas or clues?
You need to put both Maps related <meta-data> elements as direct "child" of <application> - you placed it as part of <activity> which is too deep and wrong. It should be like that:
<application android:label="#string/app_name" android:icon="#drawable/ic_launcher">
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />

android:value="xxx"/>
<activity android:name="MyActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
Add below lines in Manifest.xml
<application
android:label="#string/app_name"
android:icon="#drawable/ic_launcher">
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />

I have a tablet Genesis GT-7240, Android 4.1.1, Kernel 3.0.36+.
My manifest.xml:
<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="17" />
It is a simple app, using Google Maps and so it must be compiled with API GOOGLE.
As I testing in a real device, I checked 'Unknown sources', copied the compiled apk into 'download' folder of the tablet, and I tried install it as I always usually do.
However, has a message
X App not instaled.
Another tablet, which has Android 3.2, the same app works perfectly.
Is there a issue with Android 4.1 and Api Google compilation?

manifest file
For eclipse add this :
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
If you are using Android Studio(latest version) with gradle0.7+ then add this line:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Your Key" />
Add the Google Play services version to your app's manifest
Edit your application's AndroidManifest.xml file, and add the
following declaration within the element. This embeds the version of
Google Play services that the app was compiled with.
You just need to add <meta-data> under <application> tag into your AndroidManifest.xml
....<application>
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
I have included all the necessary fields correctly.
But still, I am not able to launch the Google map on my emulator.
Checked the internet permissions also.

Change the android:name in activity definition

to

You emulator target should be one that includes Google APIs (Google Inc.).
