向我的应用程序发送意图时，出现“无法实例化接收者”错误。看来Eclipse某种程度上看不到我的ExIntentReceiver类。我不知道为什么会这样。 ExIntentReceiver位于同一程序包（com.example.app）中。
ExIntentReceiver.java：
package com.example.app
public class ExIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals("com.example.app.START_SERVICE")) {
Log.v("service", "is started");
} else if(action.equals("com.example.app.STOP_SERVICE")) {
Log.v("service", "is stopped");
}
}
}
表现：
<receiver android:name=".ExIntentReceiver" android:exported="true">
<intent-filter>
<action android:name="com.example.app.START_SERVICE" />
<action android:name="com.example.app.STOP_SERVICE" />
</intent-filter>
</receiver>

最佳答案
您应该在自己的意图过滤器中声明动作。
<receiver android:name=".ExtIntentReceiver " android:exported="true">
<intent-filter>
<action android:name="com.example.app.START_SERVICE" />
</intent-filter>
<intent-filter>
<action android:name="com.example.app.STOP_SERVICE" />
</intent-filter>
</receiver>
除此之外，请确保为清单中的
Receiver提供正确的软件包名称。并确保您正确拼写。
