Android - 启动时启动服务 [英] Android - Start service on boot

问题描述

从我在 Stack Exchange 和其他地方看到的一切来看，我已经正确设置了一切，以便在 Android 操作系统启动时启动 IntentService.不幸的是，它没有在启动时启动，而且我没有收到任何错误.也许专家可以帮助...

From everything I've seen on Stack Exchange and elsewhere, I have everything set up correctly to start an IntentService when Android OS boots. Unfortunately it is not starting on boot, and I'm not getting any errors. Maybe the experts can help...

清单:

<?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>

用于启动的广播接收器:

BroadcastReceiver for Startup:

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:我几乎尝试了以下所有建议，并添加了日志记录，例如 Log.v("BatteryLogger", "Got to onReceive,about to start service"); 到 StartupIntentReceiver 的 onReceive 处理程序，并且没有记录任何内容.所以它甚至没有进入 BroadcastReceiver.

UPDATE: I tried just about all of the suggestions below, and I added logging such as Log.v("BatteryLogger", "Got to onReceive, about to start service"); to the onReceive handler of the StartupIntentReceiver, and nothing is ever logged. So it isn't even making it to the BroadcastReceiver.

我想我正在部署 APK 并正确测试，只是在 Eclipse 中运行 Debug 并且控制台说它成功地将它安装到我的 Xoom 平板电脑上，位于 BatteryLoggerinBatteryLogger.apk.然后为了测试，我重新启动平板电脑，然后查看 DDMS 中的日志并检查操作系统设置中的运行服务.这一切听起来是否正确，还是我遗漏了什么?再次感谢您的帮助.

I think I'm deploying the APK and testing correctly, just running Debug in Eclipse and the console says it successfully installs it to my Xoom tablet at BatteryLoggerinBatteryLogger.apk. Then to test, I reboot the tablet and then look at the logs in DDMS and check the Running Services in the OS settings. Does this all sound correct, or am I missing something? Again, any help is much appreciated.

这是一个完整的 AutoStart 应用程序示例

Well here is a complete example of an AutoStart Application

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>

autostart.java

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 - 每次执行应用程序后每次启动设备时都会弹出.

hello.java - This will pop-up everytime you start the device after executing the Applicaton once.

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();
    }
}
