I need global variable in my application. Variable will be set and periodically change in BroadcastReceiver. And I get and use it in the Thread in the Service. My code:

I create Application Class for globals variables:

    package com.bklah.blah;
    import android.app.Application;
    public class ApplicationBlah extends Application
     {
       public boolean eSettings;
       public boolean getSettings()
        {
          return this.eSettings;
        }
       public void setSettings( boolean eSettings)
        {
          this.eSettings = eSettings;
        }
     }

I decrale it in AndroidManifest file:

    <application android:icon="@drawable/icon"
                 android:label="@string/sAppName"
                 android:theme="@android:style/Theme.NoTitleBar"
                 android:name=".ApplicationBlah">
    <receiver android:name=".BroadcastBlah"
              android:process=":remote" />

I periodically change variable in cicle through BroadcastReceiver:

     public class BroadcastBlah extends BroadcastReceiver
      {
        @Override
        public void onReceive( Context context, Intent intent) 
         {
           ((ApplicationBlah)context.getApplicationContext()).setSettings( true);
           // or ...
           // ((ApplicationBlah)getApplication()).setSettings(true); 
         }
      }

And I try use variable in cicle in Thread in Service:

    public class ServiceBlah extends Service
     {
       public static Thread threadBlah = null;
       public String fUse( Context context)
        {
          boolean eSeetingsCurrent1 =((ApplicationBlah)context.getApplicationContext()).eSettings;
          boolean eSeetingsCurrent2 = ApplicationBlah.eSettings;
          boolean eSeetingsCurrent3 = ((ApplicationBlah)context.getApplicationContext()).getSettings();
          // --- all this variables always == false, but i need true from Receiver
        }

       public void fThreadBlah( final Context context)
        {
          final Handler handler = new Handler()
           {
             @Override
             public void handleMessage( Message message) { ... }
           };

          threadBlah = new Thread()
           {
             @Override
             public void run()
              {
                final Message message = handler.obtainMessage( 1, fUse( context));
                handler.sendMessage( message);
              }
           };
          threadBlah.setPriority( Thread.MAX_PRIORITY);
          threadBlah.start();
        }
     }

But I always get false in global variable. Please say what is my error?

コンテキストを使用してコンテキストを取得し、それをアプリケーションにキャストしていますが、奇妙に見えます。彼を試してみてください。うまくいくかどうかはわかりません。

((ApplicationBlah)getApplication()).setSettings(true);
