Android-启动时启动服务

从我在Stack Exchange和其他地方看到的所有内容中,我已经正确设置了所有内容,可以在启动Android OS时启动IntentService。不幸的是,它没有在启动时启动,并且我没有收到任何错误。也许专家可以帮忙…

表现:

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.phx.batterylogger"

android:versionCode="1"

android:versionName="1.0"

android:installLocation="internalOnly">

<uses-sdk android:minSdkVersion="8" />

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

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

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

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

<service android:name=".BatteryLogger"/>

<receiver android:name=".StartupIntentReceiver">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

</application>

</manifest>

用于启动的BroadcastReceiver:

package com.phx.batterylogger;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class StartupIntentReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Intent serviceIntent = new Intent(context, BatteryLogger.class);

context.startService(serviceIntent);

}

}

更新:我尝试了下面的几乎所有建议,并Log.v("BatteryLogger", "Got to onReceive, about to start service");在StartupIntentReceiver的onReceive处理程序中添加了日志记录,但从未记录过任何内容。因此,它甚至还没有到达BroadcastReceiver

我认为我正在部署APK并正确测试,只是在Eclipse中运行Debug,控制台说它已成功将其安装到我的Xoom平板电脑上,位于\ BatteryLogger \ bin \ BatteryLogger.apk。然后进行测试,我重新启动平板电脑,然后查看DDMS中的日志,并在OS设置中检查“正在运行的服务”。这听起来是否正确,还是我缺少了什么?再次感谢你的帮助。

好吧,这是一个自动启动应用程序的完整示例

AndroidManifest文件

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="pack.saltriver" android:versionCode="1" android:versionName="1.0">

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

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

<receiver android:name=".autostart">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

<activity android:name=".hello"></activity>

<service android:enabled="true" android:name=".service" />

</application>

</manifest>

自动启动

public class autostart extends BroadcastReceiver 

{

public void onReceive(Context context, Intent arg1)

{

Intent intent = new Intent(context,service.class);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

context.startForegroundService(intent);

} else {

context.startService(intent);

}

Log.i("Autostart", "started");

}

}

service.java

public class service extends Service

{

private static final String TAG = "MyService";

@Override

public IBinder onBind(Intent intent) {

return null;

}

public void onDestroy() {

Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();

Log.d(TAG, "onDestroy");

}

@Override

public void onStart(Intent intent, int startid)

{

Intent intents = new Intent(getBaseContext(),hello.class);

intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intents);

Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();

Log.d(TAG, "onStart");

}

}

hello.java-执行一次Applicaton后,每次启动设备时都会弹出此窗口。

public class hello extends Activity 

{

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Toast.makeText(getBaseContext(), "Hello........", Toast.LENGTH_LONG).show();

}

}
