Question

我正在开发一个Android应用程序，它应该在android的启动时启动。

为此，我在AndroidManifest.xml中添加了以下行

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

和

<receiver android:name=".AppBroadcastReceiver">
    <intent-filter >
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

我创建了一个新文件（新类）：

public class AppBroadCastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
            Intent i = new Intent(context, MyService.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startService(i);
        }
    }

}

但是当我启动我的Android系统时，我说我的应用程序启动但它直接崩溃

如何解决这些问题？

Answer 1

您的代码中存在拼写错误。尝试替换以下代码

<receiver android:name=".AppBroadcastReceiver">

与

<receiver android:name=".AppBroadCastReceiver">

有关您的信息，触摸屏幕与系统完成启动时启动服务无关。

更新：

<receiver android:name="com.example.openafreerdp.receiver.AppBroadCastReceiver">

启动时我的Android应用程序启动出错
