Question

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，以便在Android OS启动时启动IntentService。不幸的是它没有启动，我没有收到任何错误。也许专家可以提供帮助...

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>

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：我尝试了下面的所有建议，并将Log.v("BatteryLogger", "Got to onReceive, about to start service");等日志记录添加到StartupIntentReceiver的onReceive处理程序中，并且没有记录任何内容。所以它甚至没有进入BroadcastReceiver。

我认为我正在部署APK并正确测试，只需在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\ 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，并在操作系统设置中检查正在运行的服务。这听起来是否正确，或者我错过了什么？再次，非常感谢任何帮助。

这里有一个AutoStart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>

<强> 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");
    }
}

<强> 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Applicaton一次后，每次启动设备时都会弹出。

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();
    }
}

以下应该工作。我已经验证了。可能是你的问题在别的地方。

public class MyReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "MyReceiver");
        Intent serviceIntent = new Intent(context, Test1Service.class);
        context.startService(serviceIntent);
    }
}




public class Test1Service extends Service {
    /** Called when the activity is first created. */
    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("TAG", "Service created.");
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TAG", "Service started.");
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.d("TAG", "Service started.");
    }
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }
}

Answer 3

由于设备在启动后进入休眠状态，您的服务可能会在完成之前关闭。您需要先获得唤醒锁定。幸运的是，Support library gives us a class要做到这一点：

public class SimpleWakefulReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // This is the Intent to deliver to our service.
        Intent service = new Intent(context, SimpleWakefulService.class);

        // Start the service, keeping the device awake while it is launching.
        Log.i("SimpleWakefulReceiver", "Starting service @ " + SystemClock.elapsedRealtime());
        startWakefulService(context, service);
    }
}

然后，在您的服务中，确保释放唤醒锁：

    @Override
    protected void onHandleIntent(Intent intent) {
        // At this point SimpleWakefulReceiver is still holding a wake lock
        // for us.  We can do whatever we need to here and then tell it that
        // it can release the wakelock.

...
        Log.i("SimpleWakefulReceiver", "Completed service @ " + SystemClock.elapsedRealtime());
        SimpleWakefulReceiver.completeWakefulIntent(intent);
    }

不要忘记添加WAKE_LOCK权限：

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

Answer 4

看起来与mine非常相似，但我使用接收器的完整包名称：

<receiver android:name=".StartupIntentReceiver">

我有：

<receiver android:name="com.your.package.AutoStart">

Answer 5

我没有完整的包就取得了成功，你知道调用链在哪里被打断了吗？如果您使用Log()调试，它在什么时候不再有效？

我认为它可能在您的IntentService中，这看起来很好。

Answer 6

我找到了一种方法，可以在设备重启时使您的应用正常运行，请按照以下步骤操作。

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

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

<activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".UIBootReceiver" android:enabled="true" 
    android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>
     <service android:name=".class_Service" />
</application>

UIBootReceiver

public class UIBootReceiver extends BroadcastReceiver {

private static final String TAG = "UIBootReceiver";
@Override

    public void onReceive(Context context, Intent arg1)
    {
        Toast.makeText(context, "started", Toast.LENGTH_SHORT).show();
        Intent intent = new Intent(context,class_Service.class);
        context.startService(intent);
    }
  }

这是请求权限，无需管理此应用程序的电池节省，因此您可以稳定地在后台运行。

在MainActivity类的onCreate（）中声明以下代码：

   Intent myIntent = new Intent();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        myIntent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
        myIntent.setData(Uri.parse("package:" + 
   DeviceMovingSpeed.this.getPackageName()));
    }
    startActivity(myIntent);
