我有一个没有被实例化或调用的BroadcastReceiver,对我所做的任何帮助都表示赞赏。
它应该响应wifi连接/断开事件但不是,并且它的超类构造函数甚至都没有被调用。
MainActivity:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
广播接收器:
public class ConnectivityChangeReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.v(TAG, "action: " + intent.getAction());
Log.v(TAG, "component: " + intent.getComponent());
}
}
的AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application

android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

</activity>
<receiver
android:name=".ConnectivityChangeReceiver"
android:enabled="true">

<action android:name="android.net.ConnectivityManager.CONNECTIVITY_ACTION" />
</intent-filter>
</receiver>
</application>
</manifest>
