Android - 启动时启动服务

与天地兮比寿，与日月兮齐光。这篇文章主要讲述Android - 启动时启动服务相关的知识，希望能为你提供帮助。
从我在Stack Exchange和其他地方看到的所有东西，我已经正确设置了所有东西，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......
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>

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，并且我将诸如

Log.v("BatteryLogger", "Got to onReceive, about to start service");

之类的日志记录添加到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。
我想我正在部署APK并正确测试，只需在Eclipse中运行Debug，控制台就说它成功将它安装到我的Xoom平板电脑 BatteryLoggerbinBatteryLogger.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。
答案这是一个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>

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- 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(); } }

另一答案以下应该工作。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; } }< ?xml version="1.0" encoding="utf-8"?> < manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.test" android:versionCode="1" android:versionName="1.0" android:installLocation="internalOnly"> < uses-sdk android:minSdkVersion="8" /> < application android:icon="@drawable/icon" android:label="@string/app_name"> < 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" /> < !--< activity android:name=".MyActivity"> < intent-filter> < action android:name="android.intent.action.MAIN" /> < category android:name="android.intent.category.LAUNCHER"> < /category> < /intent-filter> < /activity> --> < service android:name=".Test1Service" android:label="@string/app_name" > < /service> < receiver android:name=".MyReceiver"> < intent-filter> < action android:name="android.intent.action.BOOT_COMPLETED" /> < /intent-filter> < /receiver> < /application> < /manifest>

另一答案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这样做：

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" />

另一答案看起来与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">

另一答案我没有完整的包装就成功了，你知道调用链在哪里被打断了吗？如果您使用Log()进行调试，它在什么时候不再有效？
我认为它可能在你的IntentService中，这一切看起来都很好。
另一答案【Android - 启动时启动服务】只是为了使搜索更容易，如评论中所述，这是不可能的，因为3.1 https://stackoverflow.com/a/19856367/6505257
