Learning Android: ‘Unable to start service Intent not found’
In the Android application that I’ve been playing around with I wrote a service which consumes the Twitter streaming API which I trigger from the app’s main activity like so:
public class MyActivity extends Activity { ... @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Intent intent = new Intent(this, TweetService.class); startService(intent); ... } }
Where TweetService is defined roughly like this:
public class TweetService extends IntentService { @Override protected void onHandleIntent(Intent intent) { // Twitter streaming API stuff goes here } }
Unfortunately when I tried to deploy the app the service wasn’t starting and I got this message in the log:
01-01 03:10:31.758: WARN/ActivityManager(106): Unable to start service Intent { cmp=com.example/.TweetService }: not foundWhat I hadn’t realised is that the service needs to be specified in the AndroidManifest.xml file but not inside the activity definition:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example" android:versionCode="1" android:versionName="1.0"> <application android:label="@string/app_name"> <activity android:name="MyActivity" android:label="@string/app_name" android:launchMode="singleInstance"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <service android:name="TweetService"></service> </application> <uses-permission android:name="android.permission.INTERNET"/> </manifest>
After adding the service definition it works fine.
