Android应用客户端架构学习

零碎的东西，边学边记，最后再做整理

1,管理全局退出思路：所有Activity注册一个广播，广播执行finish动作，例如

private BroadcastReceiver mLoggedOutReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (DEBUG) Log.d(TAG, "onReceive: " + intent);
            finish();
        }
    };

 

在onCreate中注册，并且在需要全局退出是发送广播

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        if (DEBUG) Log.d(TAG, "onCreate()");
        setDefaultKeyMode(Activity.DEFAULT_KEYS_SEARCH_LOCAL);
        registerReceiver(mLoggedOutReceiver, new IntentFilter(Foursquared.INTENT_ACTION_LOGGED_OUT));    

　　}
