我正在做一些我认为很简单的事情,就像过去在 2.3.4 机器人上做过广播接收器一样。我现在在这个小程序中使用 4.x。

这是主要的架构/流程。我希望/有一个接收器来监听自定义广播/意图。我创建了这个作为项目/apk的立场

public class FileIntegrityMonitor extends BroadcastReceiver 
{
public String CLASS_NAME = "FileIntegrityMonitor";

@Override
public void onReceive(Context context, Intent intent) 
{
    Log.d(CLASS_NAME, "Entered onReceive: got broadcast from startFIM");

    String actionReceived = intent.getAction();
    Log.d(CLASS_NAME, "Action received=" + actionReceived);

    if (actionReceived.equals(StartFIMActivity.CUSTOM_INTENT))
    {
        //start service to perform the file integrity check
        Log.d(CLASS_NAME, "start service to perform file integrity check");  


    }


}

然后我创建了一个活动作为一个单独的项目/应用程序作为驱动程序,以启动广播接收器。以后可能会用其他东西代替,但现在想把机制/通讯搞定。public class StartFIMActivity extends Activity { /** 首次创建活动时调用。*/ public static final String CUSTOM_INTENT = "com.kdms2.StartFIM.intent.action.start"; 公共字符串 CLASS_NAME = "StartFIMActivity";

@Override
public void onCreate(Bundle savedInstanceState) 
{
    Log.d(CLASS_NAME, "Entered onCreate");
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Intent i = new Intent();
    i.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES); //api  3.1+
    i.setAction(CUSTOM_INTENT);
    Log.d(CLASS_NAME, "send  brodcast to monitor");
    this.sendBroadcast(i);

}
}

现在在跟踪中,我确实在 FileIntegrityMonitor 中得到了意图,但是一条奇怪的消息表明它正在尝试运行某些方法,但我不知道为什么。错误是:E/AndroidRuntime(979): java.lang.RuntimeException: 无法实例化接收器 com.kdms2.FileIntegrityMonitor.StartFIMActivity: java.lang.ClassNotFoundException: com.kdms2.FileIntegrityMonitor.StartFIMActivity

为什么它将广播动作的活动的类名添加到广播接收器?

它是清单(接收者)中的东西吗?

<uses-sdk android:minSdkVersion="10" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <receiver android:name=".StartFIMActivity" android:enabled="true">
        <intent-filter android:priority="99999999999">
            <action android:name="com.kdms2.StartFIM.intent.action.start"/>
        </intent-filter>
    </receiver>

</application>



<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

</manifest>

活动清单

<uses-sdk android:minSdkVersion="10" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >

    <activity
        android:name=".StartFIMActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>  

</application>

</manifest>

v/r,弗兰克

您的接收者的名字是FileIntegrityMonitor,但在清单中您尝试注册StartFIMActivity<activity>and<receiver>元素。大概应该是:

<receiver android:name=".FileIntegrityMonitor" android:enabled="true">
    <intent-filter android:priority="99999999999">
        <action android:name="com.kdms2.StartFIM.intent.action.start"/>
    </intent-filter>
</receiver>

或者类似的东西。
