Helper classes not working.

    Hey folks! I have a confusing issue where the helper classes aren't calling code as expected, even though native code works just fine.

    Code (csharp):
    1.        AndroidJavaObject intent = new AndroidJavaObject ("android.content.Intent", "android.provider.Settings.ACTION_BLUETOOTH_SETTINGS");
    2.  AndroidJavaClass activityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    3.  AndroidJavaObject activity = activityClass.GetStatic<AndroidJavaObject>("currentActivity");
    4.  activity.Call("startActivity",intent);
    returns the following error:
    Code (csharp):
    2. AndroidJavaException: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.provider.Settings.ACTION_BLUETOOTH_SETTINGS }
    However, if I write the same code as a java class
    Code (csharp):
    2. package com.mostlycircle.bluetoothsettingsopener;
    3. import;
    4. import android.provider.Settings;
    5. import android.util.Log;
    6. import android.content.Intent;
    7. import com.unity3d.player.*;
    8. public class BluetoothSettingsOpener {
    9. public static void OpenBluetoothSettings()
    10. {
    11. Intent openBluetooth = new Intent(Settings.ACTION_BLUETOOTH_SETTINGS);
    12. UnityPlayer.currentActivity.startActivity(openBluetooth);
    13. }
    14. }
    and call it from unity code as so:
    Code (csharp):
    2. var ajc = new AndroidJavaClass("com.mostlycircle.bluetoothsettingsopener.BluetoothSettingsOpener");
    3. ajc.CallStatic("OpenBluetoothSettings");
    it works just fine. If anyone could provide any guidance as to why the first one doesn't work, that would be greatly appreciated!

    In Java, you are constructing the intent by passing the action using the static field on the Settings class, this is actually a helper for getting the action value (see the docs here:

    You should initialize your intent using the correct value:
    Code (CSharp):
    1. AndroidJavaObject intent = newAndroidJavaObject("android.content.Intent", "android.settings.BLUETOOTH_SETTINGS");
    *I didnt test this code, so let me know if it works.
