Native Android Activity plugin issue.

Hi All!
For the past few days I've been pulling my hair, trying to find what causes a problem with a pretty simple plugin.
So here comes the explanation:

I am trying to create a simple plugin, that just starts a native android activity. The activity is to be transparent, because I do not really want to display anything to the user. Now, you may say that I should use a Service if I want no GUI, but just a background execution. Well, in my defense, I will say that I need it to be an activity so that I can start another activity for result. For now, I will just stick to the main native activity( skipping the one for result ) because the problem comes from it.


Here we begin:

1. Entry point for the communication -> getting an instance of the java class.
Well, here is how I create the connection:

Code (csharp):

1.  public class SamplePlugin {
2.         private static SampleUnity mInstance;
3.        
4.         public static SampleUnity GetInstance() {
5.             if(mInstance == null) {
6.                 mInstance = new SampleUnity(UnityPlayer.currentActivity);
7.             }
8.             //Log.i("GET INSTANCE", "GET INSTANCE");
9.             return mInstance;
10.         }
11.     }

This way I get the instance of SampleUnity class:

Code (csharp):

1.  public class SampleUnity {
2.        
3.         private Activity mActivity;
4.        
5.         public SampleUnity( final Activity activity ) {
6.             this.mActivity = activity;
7.         }
8.    
9.         public void StartNewActivity( ) {
10.    
11.             Intent intent = new Intent(mActivity, NewActivity.class);
12.    
13.             mActivity.startActivity(intent);
14.         }
15.     }

Now let's look at the new activity:

Code (csharp):

1. public class NewActivity extends Activity{
2.    
3.         @Override
4.         public void onCreate(final Bundle mSavedInstanceState) {
5.             super.onCreate(mSavedInstanceState);
6.      
7.             // Can go with or without this contentView( I do not really need it ).
8.             Resources res = getResources();
9.             setContentView( res.getIdentifier("new_activity", "layout", this.getPackageName()));
10.          
11.             //Just for now, I use finish(), but actually startActivityForResult goes here.
12.             finish();
13.         }
14.     }

Ewww, what? A whole new activity just to close it? Well....I want to just hit you in the face with new window...
Okay so, this activity lifecycle goes as ----> onCreate() ->onDestroy()
Now the activity disappears and I am back in the game.

Now how a look at the C# part in Unity:

Code (csharp):

1. public class SamplePlugin {
2.     private static AndroidJavaObject _plugin;
3.  
4.     static SamplePlugin() {
5.         if( Application.platform != RuntimePlatform.Android )
6.             return;
7.        
8.         // find the plugin instance
9.         using( AndroidJavaClass pluginClass = new AndroidJavaClass( "com.me.unity.myplugin.SamplePlugin" ) )
10.             _plugin = pluginClass.CallStatic<AndroidJavaObject>( "GetInstance" );
11.     }
12.  
13.     public static void StartNewActivity(  ) {
14.         if( Application.platform != RuntimePlatform.Android )
15.             return;
16.  
17.         _plugin.Call( "StartNewActivity");
18.     }
19. }

And I put these lines in the manifest:

Code (csharp):

1. <activity android:name="com.me.unity.myplugin.NewActivity" >
2.  </activity>

And now, when I click the big red button in game, the magic happens:::: my new activity is launched
and immediately destroyed( "adb shell dumpsys activity" confirmed that! ).

Here comes the BOOM:

Now ... the real part of the problem.
When I am back in my game, I quit the game as soon as possible( using Application.Quit() ).
"Oh, mah game is closed." - my first thought after that.
Well..... I tried launching the game again and the big bad dump hit me in the face:

And one NullPointerException , or two...
So. After the process is killed I can launch my game again.

Remember when I said that I wanted to make my activity transparent? Well, yeah, I just add a theme to my activity in the manifest:

Code (csharp):

1. <activity android:name="com.me.unity.myplugin.NewActivity"
2.                       android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen">
3. </activity>

or

Code (csharp):

1. <activity android:name="com.me.unity.myplugin.NewActivity"
2.                       android:theme="@android:style/Theme.NoDisplay">
3. </activity>

This does the trick.

So...here are some different scenarios :
- When I launch the native activity, it executes and finishes. Then I am back in my game. If I minimize the game, then open it again( its state is restored ) and THEN I quit it, it quits as it should. No problems occur.

- When I launch the native activity, it executes and finishes. Then I am back in my game. Sometimes(not always) if I wait a few seconds before I quit it, it quits normally. No problems occur( sometimes ).

- When I put Theme.NoDisplay on my activity, after it finishes and I am back in the game, I quit the game and the problem I mentioned happens( 100% ).

- I put Theme.Translucent.NoTitleBar.Fullscreen on my activity. After it finishes, I am back in the game. I wait a few seconds and quit the game. Sometimes the problem occurs, sometimes not. ( 50% ).

- I put no theme on my activity. After it finishes, I am back in the game. I wait a few seconds( less than when I put Translucent theme), I quit the game and usually there is not problem. If I quit the game too fast, the problem occurs.

- Setting content view in my activity ( setContentView ) makes the game more likely to quit without problem. But still, the problem occurs sometimes.

- I tried with BroadcastReceiver from which I launch the new activity -> same behaviour.

- I cannot confirm 100% but if I let my activity go through all of its states when created( not call finish in onCreate ) , the problem does not occur( or may happen but really rarely ).

- I tried putting a timer in onCreate, which executes finish() on my activity ( through a handler - on the main thread ) when it finishes. I tested it a few times, and when the native activity is closed and I quit the game, there is not problem.

When the problem occurs, I usually execute the "adb shell dump sys activity" in the terminal, and I see that UnityPlayerNativeActivity is in the state: Activities Waiting to Stop.

Soooo I smell there is some background dark magic going on, which somehow keeps the process alive.

So these are the scenarios I can think of ( that I have tested ). There may be 1 or 2 I am missing but I tested tons of different options, and nothing helped at 100%.
To me, this behaviour is pretty much UNKNOWN. So I hope there is somebody who can tell me where I go wrong, or what option can I try to solve the issue.

Oh... and I hope I did not forget to show any important part of the project.

Here comes my apology:
- Sorry if I misconstructed, misspelled or anything similar with the English language.
- Sorry for burning your eyes with the long post.
- I want to apologize to myself for creating a big bald spot on the back of my head.

 

SIGSEV 11 and memory address 0x00000000 as your case it's commonly a NullPointer issue.

I would start looking if UnityPlayer.currentActivity returns the current activity Context on your Activity.

Also, if you are using Android layouts and other resources, you need to copy them on Android/Plugins/res folder or similar because the R class is regenerated by Unity when building your game.

 

Hi.
I am not sure what you mean with " if UnityPlayer.currentActivity returns the current activity Context on your Activity", but when the new activity is started, it is placed in the UnityPlayerNativeActivity ' s task back stack, which creates the following stack:

Task #NUMBER:
#2 : com.me.myunitygame / com.me.unity.myplugin.NewActivity;
#1 : com.me.myunitygame / com.unity3d.player.UnityPlayerNativeActivity;

This looks good to me. So when I finish the NewActivity, it is properly removed from the back stack. After that the focus goes directly to UnityPlayerNativeActivity, which still looks good to me. When I close the application (depending on one of the scenarios mentioned above ), the problem occurs.
Strange thing is that on some devices( usually with older android OS ) there is NO problem at all. It never occurs.

I can confirm that the player is not releasing the native resources. When I close the app, no "Unregistering JNI method..." occurs( as it usually does when app is closing without problems).

However, I will file a bug report asap. Thank you for your time.

 

hi,guys.I met the same problem today...so,if the problem got resolved ? Thank you so much

 

i have same too, is there any solution ?

 

@Kukuruz we had run into a (perhaps?) similar issue, where if the player will close the game and then launch it immediately back again, the game would crash on startup.

I even remember opening a bug for it (case 667260).

The issue is that Unity is dumping some resources (cleaning up) when you close the game, but it's not really closed just yet. When you launch it at that point again, it crashes.

There was never a fix from Unity for our case, so we just had to work around it by not calling Application.Quit(). i can't recall the exact workaround we pulled but i'll have to look it up if you're interested.
