Hi,
I have an error when I called this methods :
package com.baringsprod.naandroidunity;
import com.unity3d.player.UnityPlayerActivity;
public class UnityBridge extends UnityPlayerActivity
{
public static final String STATS\_NAME = “NaStats”;
public static final String STATS\_MAXLEVEL\_TOK = “NaStatsMaxLevel”;
public enum NaGameType
{
kEasy,
kMedium,
kExpert
}
private int getMaxLevelForType\_( NaGameType type )
{
return getSharedPreferences(STATS\_NAME, 0).getInt(STATS\_MAXLEVEL\_TOK + type, 0);
}
public int getMaxLevelEasy()
{
return getMaxLevelForType\_( NaGameType.kEasy );
}
public int getMaxLevelMedium()
{
return getMaxLevelForType\_( NaGameType.kMedium );
}
public int getMaxLevelExpert()
{
return getMaxLevelForType\_( NaGameType.kExpert );
}
I call them with this C# script :
// Get Android context
AndroidJavaClass unityPlayer = new AndroidJavaClass(“com.unity3d.player.UnityPlayerActivity”);
AndroidJavaObject activity = unityPlayer.GetStatic(“currentActivity”);
AndroidJavaObject app = activity.Call(“getApplicationContext”);
// Install DeployGate, make sure it will not called twice in your app
deployGate = new AndroidJavaClass(“com.baringsprod.naandroidunity.UnityBridge”);
activity.Call(“runOnUiThread”, new AndroidJavaRunnable(() =\>
{
recupDiff0 = deployGate.CallStatic(“getMaxLevelEasy”, app);
recupDiff1 = deployGate.CallStatic(“getMaxLevelMedium”, app);
recupDiff2 = deployGate.CallStatic(“getMaxLevelExpert”, app);
NAUtil.UnlockLevelForDifficulty(recupDiff0,0);
NAUtil.UnlockLevelForDifficulty(recupDiff1,1);
NAUtil.UnlockLevelForDifficulty(recupDiff2,2);
Debug.Log("!!! GetPreferenceString success - level returned = " + recupDiff0 + " / " + recupDiff1 + " / " + recupDiff2);
}));
What am I doing wrong ?
Thanks for the help !

What is the error your are receiving ? and on which line is it thrown ?
Basically, if you extend Unity’s default activity, then your activity (e.g: UnityBridge _is_ the default activity now).
You should define it in the AndroidManifest.xml as well, but after you do that, this call will return UnityBridge:
```csharp
AndroidJavaObject activity = unityPlayer.GetStatic("currentActivity"); // This is UnityBridge, returned as an Activity reference
```
The code you’re later invoking on UnityBridge is using calling it on the **class** and not on the specific **instance.**
Try the following code (i can’t test it, but it should be the right direction):
```csharp
// Get Android context
AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayerActivity");
AndroidJavaObject deployGate = unityPlayer.GetStatic("currentActivity");
deployGate.Call("runOnUiThread", new AndroidJavaRunnable(() =>
{
recupDiff0 = deployGate.Call("getMaxLevelEasy");
recupDiff1 = deployGate.Call("getMaxLevelMedium");
recupDiff2 = deployGate.Call("getMaxLevelExpert");
NAUtil.UnlockLevelForDifficulty(recupDiff0,0);
NAUtil.UnlockLevelForDifficulty(recupDiff1,1);
NAUtil.UnlockLevelForDifficulty(recupDiff2,2);
Debug.Log("!!!!!! GetPreferenceString success - level returned = " + recupDiff0 + " / " + recupDiff1 + " / " + recupDiff2);
}));
```
Let me know if that helped 🙂

Hi,
First of all :thank you very much for your help.
But I still have an error :

My manifest :

And the code I used :
try{
intrecupDiff0=0;
intrecupDiff1=0;
intrecupDiff2=0;
//GetAndroid context
AndroidJavaClassunityPlayer=newAndroidJavaClass(“com.unity3d.player.UnityPlayerActivity”);
AndroidJavaObjectdeployGate=unityPlayer.GetStatic(“currentActivity”);
deployGate.Call(“runOnUiThread”,newAndroidJavaRunnable(()=\>
{
recupDiff0=deployGate.Call(“getMaxLevelEasy”);
recupDiff1=deployGate.Call(“getMaxLevelMedium”);
recupDiff2=deployGate.Call(“getMaxLevelExpert”);
NAUtil.UnlockLevelForDifficulty(recupDiff0,0);
NAUtil.UnlockLevelForDifficulty(recupDiff1,1);
NAUtil.UnlockLevelForDifficulty(recupDiff2,2);
Debug.Log(“!!!PlayerPrefsAndroidsuccess-levelreturned=”+recupDiff0+“/”+recupDiff1+“/”+recupDiff2);
}));
}catch(Exception ee){
Debug.LogWarning(“!!!EXCEPTIONPlayerPrefsAndroid:”+ee.ToString());
}
Sorry and thanks again !

Ok i see 2 things now:
- The currentActivity static field is on com.unity3d.player.UnityPlayer and not on UnityPlayerActivity. Change the code to init the androidjavaclass with that.
- Are you declaring your new activity in the manifest? You should do that in case you don’t.
Let me know if that helped 🙂
