Unable to find explicit activity class {}; have you declared this activity in your AndroidManifest.xml

Question

I'm trying unzip some files in background, so I use IntentService like in google's tutorial. My service class declared in AndroidManifest like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.osmdroid">

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="21" />


<application
    android:configChanges="orientation|screenSize|keyboardHidden"
    android:hardwareAccelerated="true"
    android:icon="@drawable/ecn_icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >


    <activity
        android:name=".MapActivity"
        android:icon="@drawable/ecn_icon"
        android:label="test" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity
        android:name=".SettingsActivity"
        android:label="@string/title_activity_settings">
    </activity>
    <service
        android:name=".UnZipService"
        android:exported="false"/>
</application>

In activity, I have

IntentFilter intentFilter = new IntentFilter(DownloadManager
            .ACTION_DOWNLOAD_COMPLETE);

    receiverDownloadComplete = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            long reference = intent.getLongExtra(DownloadManager
                    .EXTRA_DOWNLOAD_ID, -1);
            if (myDownloadReference == reference) {

                     ...
                switch (status) {
                    case DownloadManager.STATUS_SUCCESSFUL:

                        Intent mServiceIntent = new Intent(context, UnZipService.class);
                        mServiceIntent.setData(Uri.parse(savedFilePath));
                        startActivity(mServiceIntent);

                        break;
                    ...
                }
                cursor.close();
            }
        }
    };
    registerReceiver(receiverDownloadComplete, intentFilter);

And service here:

public class UnZipService extends IntentService {
public UnZipService() {
    super("UnZipService");
}

@Override
protected void onHandleIntent(Intent workIntent) {
    String dataString = workIntent.getDataString();
    Log.v("IntentURI", dataString);
    Toast.makeText(this, "Installing....", Toast.LENGTH_SHORT).show();
}

It should show toast just for test, but I always get an error:

Both (class and activity) in same folder (org.osmdroid). Seems like paths is ok, but the problem appears and I have no more ideas...

Solution

You are starting a service as an activity

Change

Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startActivity(mServiceIntent);

to

Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startService(mServiceIntent); // Only this line is changed
