Question

我正在尝试编写一个在启动时启动的应用程序。我的接收器工作，我的应用程序启动时启动，但由于ActivityNotFoundException它崩溃。我可能在某个地方弄明白了。请帮忙看看。

这是接收器代码，LocationLock.class只是用来锁定手机的东西。

public class MyStartupIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent){
    Intent myStarterIntent = new Intent(context, LocationLock.class);
    myStarterIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(myStarterIntent);
}
}

这是清单：

<?xml version="1.0" encoding="utf-8"?>

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".LocationLock$Controller"
              android:label="@string/app_name_controller">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".LocationLock"
        android:label="@string/app_name"
        android:permission="android.permission.BIND_DEVICE_ADMIN">
        <meta-data android:name="android.app.device_admin"
                   android:resource="@xml/device_admin" />
        <intent-filter>
            <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
        </intent-filter>
    </receiver>
    <receiver android:name=".MyStartupIntentReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />      
        </intent-filter>
    </receiver>
</application>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

</manifest>

以下是错误：

也许我不能一个接一个地列出两个接收器，但MyStartupIntentReceiver没有与之关联的活动。

非常感谢任何帮助！

Answer 1

您正在尝试启动接收器类：Intent myStarterIntent = new Intent(context, LocationLock.class);，因为在清单文件中它被声明为接收器类：<receiver android:name=".LocationLock"所以将此声明修改为activiy：

<activity
    android:name=".LocationLock"
    android:windowSoftInputMode="stateVisible|adjustResize" >
</activity>

Answer 2

您是否尝试将其定义为清单中的活动？

例如，在您的部分中：

<activity android:name=".MyStartupIntentReceiver"
          android:launchMode="singleTop"
          android:screenOrientation="portrait"
          android:noHistory="true" />
