为什么在我的手机屏幕关闭时没有调用onReceive方法？

Question

我正在调试我的应用，我遇到了一个有趣的问题。我的onReceive方法中有一个断点，只有当我的手机屏幕打开（唤醒）时，程序才停在那里。

为什么？

如果您有任何机会需要我的代码：

 private void gcmInit() {

    mRegistrationProgressBar = (ProgressBar) findViewById(R.id.registrationProgressBar);
    mRegistrationBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            mRegistrationProgressBar.setVisibility(ProgressBar.GONE);
            SharedPreferences sharedPreferences =
                    PreferenceManager.getDefaultSharedPreferences(context);
            boolean sentToken = sharedPreferences
                    .getBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false);
            if (sentToken) {
               // mInformationTextView.setText(getString(R.string.gcm_send_message));
            } else {
               // mInformationTextView.setText(getString(R.string.token_error_message));
            }
        }
    };

   if (checkPlayServices()) {
            // Start IntentService to register this application with GCM.
            Intent intent = new Intent(this, RegistrationIntentService.class);
            startService(intent);
        }

}

另外，我的MainActivity中还有这两种方法：

 @Override
protected void onResume() {
    super.onResume();
    LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
            new IntentFilter(QuickstartPreferences.REGISTRATION_COMPLETE));
}

@Override
protected void onPause() {
    LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
    super.onPause();
}

我的清单，我注册接收器：

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">

    <!-- GCM START -->
    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.example.android.bluetoothchat" />
        </intent-filter>
    </receiver>

    <service
        android:name="com.example.android.gcm.MyGcmListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>
    <service

        android:exported="false">

            <action android:name="com.google.android.gms.iid.InstanceID"/>
        </intent-filter>
    </service>
    <service
        android:name="com.example.android.gcm.RegistrationIntentService"
        android:exported="false">
    </service>

    <!-- GCM END -->
    <activity
        android:name=".MainActivity"
        android:configChanges="orientation|keyboardHidden"
        android:screenOrientation="portrait"

        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    <activity

        android:configChanges="orientation|keyboardHidden"
        android:label="@string/select_device"
        android:theme="@android:style/Theme.Holo.Dialog"/>

</application>
