Android 8.0 BroadcastReceiver静态注册大部分取消，动态注册，有序广播

Android 8.0 移除大部分静态注册广播：https://developer.android.com/reference/android/content/BroadcastReceiver
解决方案：动态注册广播

在Activity中对广播接收进行动态注册实现全局网络监听

public class NetWorkStateReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        NLog.i(Constants.TAG, "网络状态发生变化");
        //检测API是不是小于21，因为到了API21之后getNetworkInfo(int networkType)方法被弃用
        if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.LOLLIPOP) {

            //获得ConnectivityManager对象
            ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

            //获取ConnectivityManager对象对应的NetworkInfo对象
            //获取WIFI连接的信息
            NetworkInfo wifiNetworkInfo = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            //获取移动数据连接的信息
            NetworkInfo dataNetworkInfo = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            if (wifiNetworkInfo.isConnected() && dataNetworkInfo.isConnected()) {
                //Toast.makeText(context, "WIFI已连接,移动数据已连接", Toast.LENGTH_SHORT).show();
            } else if (wifiNetworkInfo.isConnected() && !dataNetworkInfo.isConnected()) {
                //Toast.makeText(context, "WIFI已连接,移动数据已断开", Toast.LENGTH_SHORT).show();
            } else if (!wifiNetworkInfo.isConnected() && dataNetworkInfo.isConnected()) {
                //Toast.makeText(context, "WIFI已断开,移动数据已连接", Toast.LENGTH_SHORT).show();
            } else {
                //Toast.makeText(context, "WIFI已断开,移动数据已断开", Toast.LENGTH_SHORT).show();
            }
        } else {
            NLog.i(Constants.TAG, "API level 大于21");
            //获得ConnectivityManager对象
            ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

            //获取所有网络连接的信息
            Network[] networks = connMgr.getAllNetworks();
            //用于存放网络连接信息
            StringBuilder sb = new StringBuilder();
            //通过循环将网络信息逐个取出来
            for (int i = 0; i < networks.length; i++) {
                //获取ConnectivityManager对象对应的NetworkInfo对象
                NetworkInfo networkInfo = connMgr.getNetworkInfo(networks[i]);
                sb.append(networkInfo.getTypeName() + " connect is " + networkInfo.isConnected());
            }
            Toast.makeText(context, sb.toString(), Toast.LENGTH_SHORT).show();
        }
    }

}

动态注册广播，最好是在BaseActivity中使用

public abstract class BaseActivity  extends AppCompatActivity {
    private ImmersionBar mImmersionBar;
    //网络状态监听库
    NetWorkStateReceiver netWorkStateReceiver;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        //iconfont的统一使用
        LayoutInflaterCompat.setFactory(getLayoutInflater(), new IconfontLayoutFactory(this, getDelegate()));
        super.onCreate(savedInstanceState);
        setContentView(getViewId());
        mImmersionBar = ImmersionBar.with(this).statusBarColor(R.color.colorPrimary);
        mImmersionBar.init();   //所有子类都将继承这些相同的属性
        ButterKnife.bind(this);
        initViews();

    }

    public abstract int getViewId();

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mImmersionBar != null)
            mImmersionBar.destroy();  //必须调用该方法，防止内存泄漏，不调用该方法，如果界面bar发生改变，在不关闭app的情况下，退出此界面再进入将记忆最后一次bar改变的状态
    }

    protected abstract void initViews();

    @Override
    protected void onResume() {
        if (netWorkStateReceiver == null) {
            netWorkStateReceiver = new NetWorkStateReceiver();
        }
        IntentFilter filter = new IntentFilter();
        filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
        registerReceiver(netWorkStateReceiver, filter);
        LogUtils.e("注册");
        super.onResume();
    }

    //onPause()方法注销
    @Override
    protected void onPause() {
        unregisterReceiver(netWorkStateReceiver);
        LogUtils.e("注销");
        super.onPause();
    }
}
