My application contains 2 activities A and B. B is opened with startActivity(intent) in A, when B is closed with finish(), I found the method finalize() of B is not called.
My question is: How to force Activity to call finalize() when it is closed with finish()?

I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.
In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.
However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.
The default behavior from my observation is if current activity force closes Android tries to go to previous activity on stack How can I control this behavior? I want force close to close all activities

I have checked on this group and realise it must be because I have not closed a cursor somewhere but I have checked a million times and I am absolutely sure I always either call startManagingCursor() or close all my cursors explicitly.
Yet I still get these exceptions and it's not just the odd one - sometimes I get 5 in a row! The only thing I can think of it that I have mis-understood somewhere along the line and I am misusing cursors somehow!
Experts: My MainActivity launches a SubActivity by calling: startActivityForResult(intent, REQ_CODE); The SubActivity shows a dialog that has two buttons: Yes, No For the dialog, I've the following code: public void onClick(DialogInterface dialog, int whichButton) {/* User clicked OK */setResult(DialogInterface. BUTTON_POSITIVE) ;finish();

View 3 Replies View RelatedMy application creates a database on the fly and also populates it. The problem is I get a "Attempt to Finalize Cursor That has not been closed" error in logcat which mainly refers to this function.
Code:
public static void populateFromDatabase(){
/* if the database is empty just throw in the question */
Cursor c = AppData.db.db.rawQuery("SELECT * FROM question", null);
if (c != null && c.getCount() == 0){
c.moveToFirst() ;
int count = 0 ;
while(!c.isAfterLast()){

My question is I am closing the cursor in all occasions so why this error ? Also note that i call this function only once in the program and the logcat error points to this.
I have an Android application with a main activity that is the tabhost. I'm adding multiple tabs to the tabhost with an intent to several activities.
My problem is that these activities are not created (onCreate is not called) until I click on the tab. This is a problem because I need to register broadcastreceivers: there may be broadcasts that are sent -before- a particular tab is opened.
I tried to work around this by:
Setting my receivers as static and registering from somewhere else. This is not possible because I need to call into methods.
Calling into tabHost.setCurrentTabByTag(the_tag) and then switching back to my root tab. This only works sometimes and this is a very ugly solution imo.
Not using activities but just using views instead. Also not a very elegant solution because it turns my tabHost activity into one huge master class doing all kinds of unrelated things.
I'm writing a widget with a configuration activity which calls the following method when its OK button is clicked:
CODE:..............
This is almost verbatim from the documentation. widget_id holds the widget ID that was dug up during the activity's onCreate().
When I place an instance of the widget on the home screen, I've verified that I get the expected sequence of events:
onReceive() gets an ACTION_APPWIDGET_ENABLED if it's the first one.
onUpdate() gets called (in which I detect that the widget isn't configured and draw something as a default action).
The configuration activity appears.
When I press OK, the ok() method above gets called.
The method gets all the way through to the finish() and the configuration activity goes away, but there's no call to onUpdate() or onReceive() after this point. (The widget itself has no updatePeriodMillis.) I end up with a widget on the screen that has the results of my default action but never gets updated.
If I set the widget up without a configuration activity, it gets updated when created and everything works as expected (just without the configured bits).
For an unknown reason, I can't get my application leaving properly so that when I push the home button and the app icon again I resume where I was in the app....But I would like to force the application to restart at the first activity...I suppose this has something to do with onDestroy() or maybe onPause() but I don't know what to do..

View 2 Replies View RelatedI have an application, where I need to change the language through a settings menu. Now this part works perfectly, but it doesn't change the language for activities that have gone through onCreate.
I got a TabHost, and 2 tabs in it, from the tabs you can get to settings.
Refreshing the TabHost isn't an issue, as it's fairly small, however both the 2 tabs are quite large views, and having a function to manually update all the strings seem unnecessarily difficult. Is there any way to force the activity to recreate itself and trigger a new onCreate?
I tried having a static function in the tabhost that clears all tabs and recreates them, this refreshes the tab titles, but not the content in the tabs.
I want my Activity to be always in portrait mode and I do NOT want the onDestroy() method to be called. There are some interesting articles about that at: http://www.androidguys.com/2008/11/24/rotational-forces-part-four/
The solution seems to be: In AndroidManifest.xml:
CODE:...............
I've tried it and it seems to work. Is there any other alternative or is it the correct solution?
My app keeps force closing before it starts, eclipse returns no errors in my code and my xml is good.
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class main extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button myScanButton = (Button) findViewById(R.id.myScanButton); myScanButton.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} } );
} EditText totalbox = (EditText) findViewById(R.id.totalbox);
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) { if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
// Handle successful scan totalbox.setText(contents)
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel totalbox.setText("@string/bummer");
} } } }
Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.
My activity contains an editable text view and I would like to automatically show the soft keyboard when the activity start. Anyone knows how to do it?
I tried this:

A button on our screen causes an activity to be shown that has a "dialog" theme. We are having an issue were if you click the button quickly twice in a row, the dialog activity is opened twice.
Typically I would expect that when a new activity is started, the underlying activity is immediately stopped, and thus accepts no further input.
However, since the dialog themed activity does not take over the whole screen, I think the underlying activity is only paused, not stopped and thus the buttons are still accessible.
Which brings me to my question... Is there a way to force the dialog themed activity into a modal state where the user can't click the buttons on the activity below?
I could probably manually accomplish this by disabling everything in onPause, and reenabling it in onResume, but this seems like a lot of work!
Been trying to call Preferences.java class using:
Intent settingsActivity = new Intent(getBaseContext(), Preferences.class);

Any ideas why it's force closing even though I have the Activity defined in the Manifest.xml?
Is there any way for an activity to register for being notified if a wait/force close dialog is shown or alternatively if the user selects force close, a way to detect that in ondestroy()?
View 6 Replies View RelatedSo I read through the SDK docs and I thought that calling a new activity(browser) as part of a task (myTask) will mean that activity* (browser) will close when a user closes the task (myTask) But I am left with a browser window.
Here is my scenario (in sudo code);

Question 1: What is the cleanest way to ensure that when a user closes my app, any outside activities called will be closed to.
Question 2: Does a callback URl start a new Task, or use one in the stack if available?
I was wondering if it is possible to force the RecognizerIntent Activity (or any other Activity) to stay cached so that the launch time would be faster.
View 2 Replies View RelatedI have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.
Solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?
I own an xperia mini pro and I can replicate the issue always now. When I get an incoming call while the screen is off, if you slide out the keyboard (without opening the screen lock), immediately I get a Force close error for com.android.phone. I have Lookout Mobile security along with SayMyName installed. I have tried removing both, but the problem does not seem to go off. I am using Zeam as my home screen. On FC, SayMyName continues to call out the caller (or number if its not recognized), but the phone application crashes and on closing the FC pop up, the GSM mobile connection reinitiates (I am not in 3G).
Its just like when you switch on the phone after a shutdown. I have even tried changing home screen (ADW same problem), but seems like this issue persists. The problem is I keep my phone in a pouch attached to my belt and when I get a call, many times while bringing out the phone, the sliding of the keyboard happens and I get an FC. Then, there is no way to make out who had called and its very irritating (the call log does not register the call due to the FC).
Is there a way to notify an activity/service of a force-close request right before it gets killed?
I mean when the user hits the force close button in Menu>Settings>Applications>Manage applications>app name>Force Close.
I'm trying to bring up the standard window for Bluetooth Settings (with Device name, Discoverability etc). However, general approach with startActivity(intent) ends with NullPointerException pointing to BluetoothSettings.java onCreate:135. Checking with the Android code, I've found that at line 135 they get some extras from the intent. So I prepare the same extras (names I've found in android core BluetoothDevicePicker interface) and issue it -- the same effect with NullPointerException. Might be the wrongs names of the extras I prepare? So is there a way I can see those extras (with names especially) from the intent the system itself submits when I open Bluetooth Settings manually acting like a user. Code...
