Android :: Android Force Close For Activity Class
Jul 9, 2010
When I start my (soon-to-be) android game (from eclipse) it opens, but immediately force-closes.
Logcat says:
07-09 17:12:35.709: ERROR/AndroidRuntime(3866): Uncaught handler: thread main exiting due to uncaught exception

07-09 17:12:35.719: ERROR/AndroidRuntime(3866): ... 11 more
The interesting line here is (I think):
07-09 17:12:35.719: ERROR/AndroidRuntime(3866): Caused by: java.lang.ClassNotFoundException: org.anselm.eickhoff.rhythm.RhythmGameActivity in loader dalvik.system.PathClassLoader@4001e740
Which surprises me, because I have this class (in the right package)
Edit: to clarify, added the first line which I had omitted (together with the imports)
package org.anselm.eickhoff.rhythm;
...
public class RhythmGameActivity extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
} @Override public void onPause() {
} }
and that's all it does!
I also registered it in the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.anselm.eickhoff.rhythm"
android:versionCode="1" android:versionName="pre-alpha">
<uses-permission android:name="android.permission.INTERNET" />
<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:hasCode="false">
<activity android:name=".RhythmGameActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

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.

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()?

So 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);
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?

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'd like to have some emergency cleanup code execute just before my app crashes. I tried using onDestroy(),, onFinal() and finalize() to no avail. Is this possible in an Android Activity?

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

I'm new to Java and android development. In my application I need data which is accessible for a few activities. I've read that a good solution is to use Application class for this. So I use it like this:
public class MyApplication extends Application {
private String str;
public String getStr(){
return str;
}
public void setStr(String s){
str = s;
}
}
and I can access this variable from activity like this:........................................

I created an application which is asynchronously communicating with the server. When the application makes a server request a new dialog (activity) with "loading" notification is created. The main activity implements methods for handling server responses and I would like to close the foreground activity when the main activity receives the answer from the server.

I've noticed that whenever I introduce some new awful bug to my app and it crashes, Android just keeps starting it up over and over again. I eventually have to hit the dial button on the phone just to make my app lose focus. I searched this group's posts and the developer documents.I can't find anything about this. Is this usual behavior? If so, is there some way to disable it? Maybe it's just my coming from a desktop background, but I kind of think that when something is closed, it should stay closed, especially if the reason it was closed was that it crashed. And of course, I hope my final app never force closes, but with all the different hardware you never know.

Is there an app that lets you set a countdown timer on another app which causes it to force close. For example, I use my Eris as my MP3 player and would like to listen to it while I go to sleep, however I don't wanna let it play all night while I'm sleeping maybe just an hour or so.*Edit* Nevermind I found an app that does the job. Its called Music Sleep. It lets you set a timer that will close your music app in case anyone else was interested. It only costs 99 cents

The ApplicationManager is killing the process of my application when the user presses on "FORCE STOP" on the Aplication Manager.According to the documentation a broadcast action is.The user has restarted a package, and all of its processes have been killed. All runtime state associated with it (processes, alarms, notifications, etc) should be removed. *Note that the restarted package does not receive this broadcast.* The data contains the name of the package.How can I listen that action in my application; I have tried creating a BroadcastReceiver on my package, but the onReceive() is not called.

I have a customer who upgraded his app (that I wrote and publish) and now it's force closing immediately upon launch. There is critical payroll data contained within the app so it's important that we are able to recover the data. If I could see the output of the log (as from logcat), I'm sure I could diagnose the problem, but the user is not technical and cannot use a shell. Is there a way to access the user's log from within the phone?

It is basically in a force close loop because it's the home application, ADW Launcher btw (might want to avoid it.
How can I recover this without resetting the phone? Some way to get the settings menu up or something so I can uninstall this piece of trash app?

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.
