Hi,

Using SDL for Android, you are supposed to call your project SDLActivity, because this name is hard-coded in SDL/src/core/android/SDL_android.cpp. This means that you only can install one SDL app on your phone or tablet. If you try to install another, with a different name (specified in the res/values/strings.xml file), it will overwrite the first app. How are you supposed to prevent this?

Hi,

I'm using a different approach to this. I'm referencing my activity from AndroidManifest.xml and then create a new class with a very few lines of code:
Code:
package org.bennugd.samplegame;

import org.libsdl.app.SDLActivity;
import android.os.*;

/*
 * A sample wrapper class that just calls SDLActivity
 */

public class MyGame extends SDLActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
   
    protected void onDestroy() {
        super.onDestroy();
    }
}

AndroidManifest.xml looks like this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="org.bennugd.samplegame"
      android:versionCode="1"
      android:versionName="1.0">
        <application android:label="@string/app_name" android:icon="@drawable/icon" android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        <activity android:name="MyGame"
                  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>
    <uses-sdk android:minSdkVersion="9" />
    <uses-feature android:glEsVersion="0x00020000" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>


And I can use all of SDL2's code without any modification. It seems to be working fine but I'm pretty new to Java, so I might be missing something.

Regards and hope this is helpful.

The solution from josebagar works, it is simple and elegant. Thanks!

One small addition: in the ant build file the line
<project name="SDLActivity" default="help">
should be modified to
<project name="MyGame" default="help">

PS
Vivat SDL for Android! If you code in C++11, then it's better and easier then android's own java toolbox!

Thanks for the note :)

If the approach is correct and people like it, it might be a good idea to add the instructions to README.android as this will probably be of interest to a lot of people in the future.
