Android: Autostart app and load preferences
- by BBoom
Hi, I have a problem with initializing my app properly after the autostart.
I've managed to get an autostart to work, after a reboot the app is shown as started but the timer's are not.
My guess is that the "onCreate" function of MyApp is not called when I call the context.startService(). The timers are set in the doActivity() function of MyApp.
I would greatly appreciate any tips on what I could be doing wrong or links to good tutorials. :)
The manifest:
<activity android:name=".MyApp"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="MyApp_Receiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>[/syntax]
MyApp_Receiver is a BoradcastReciever with the following two functions
public void onReceive(Context context, Intent intent) {
// Do Autostart if intent is "BOOT_COMPLETED"
if ((intent.getAction() != null) && (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")))
{
// Start the service
context.startService(new Intent(context, MyApp.class));
}
// Else do activity
else
MAIN_ACTIVITY.doActivity();
}
public static void setMainActivity(MyApp activity)
{
MAIN_ACTIVITY = activity;
}
MyApp extends PreferenceActivity and has an onCreate() and a doActivity(), the doActivity() reads out the preferences and sets a timer depending on them.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Show preferences
addPreferencesFromResource(R.xml.preferences);;
// Register Preference Click Listeners
getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
// Prepare for one-shot alarms
if (mIntent == null)
{
mIntent = new Intent(MyApp.this, MyApp_Receiver.class);
mSender = PendingIntent.getBroadcast(MyApp.this,
0, mIntent, 0);
MyApp_Receiver.setMainActivity(this);
}
// Refresh and set all timers on start
doActivity();
}
