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();
}
}
