首先，使用registerReceiver()方法在代码中注册BroadcastReceiver，并在onCreate()方法中进行调用。其次，确保您的BroadcastReceiver正确地过滤了要接收的广播意图。最后，请确保AndroidManifest.xml中未声明所有使用动态BroadcastReceiver的广播接收器。以下是代码示例：

1.在代码中注册BroadcastReceiver：

BroadcastReceiver myReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // 处理接收到的广播内容 } };

IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("com.example.MY_ACTION"); registerReceiver(myReceiver, intentFilter);

2.确保过滤要接收的广播意图：

BroadcastReceiver myReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if ("com.example.MY_ACTION".equals(intent.getAction())) { // 处理接收到的广播内容 } } };

3.确保未在AndroidManifest.xml中声明动态BroadcastReceiver：
