Adroid 广播接收器在试图接收启动完成或屏幕关闭时无法工作
原标题:Android broadcast receiver not working when trying to receive bootcomplete or screen off

所以我正在开发一个定制的锁屏幕

但我的收音机却会开火

我的单子:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.alexander.fuchs.lockscreen"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".app"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver 
            android:name=".myreceiver">
            <intent-filter>
                <action android:name="android.intent.action.SCREEN_OFF"/>
                <action android:name="android.intent.action.SCREEN_ON"/>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>
    </application>

</manifest>

我的接收器:

public class myreceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("receiver","works");
        Toast.makeText(context,"works",Toast.LENGTH_LONG).show();
        Intent in=new Intent(context,app.class);
         context.startActivity(in);
    }
}

the receiver should show me that it is fired :D but ther aren t any logs in logcat

问题回答

well , for the screen off and screen on , this cannot be inside the manifest , but only at runtime . see this: http://thinkandroid.wordpress.com/2010/01/24/handling-screen-off-and-screen-on-intents/

开始的时候,它必须列在清单中,所以它有其他问题。请检查班级的路径。这肯定是问题的根源。
