Android : How To Do Some Init Operation Immediately After Install

Sep 29, 2009

There is a big database(15M) in my application, it is too big to download the apk if I publish the source database in myapp.apk. So I encode the db to binary files(300k). But the new problem is I should decode binary files and create the database(with data), this procedure take about several minutes, so I can NOT do this in SQLiteOpenHelper.onCreate(), this is too slow for user experience(though it is a one time procedure, it is still unacceptable).

My application has NO main activity entry in launcher, the main entry is Broadcast Receiver.on Receive, the information should display to user immediately when receiving the broadcast, so I have no chance to display a several minutes "Initializing, please waiting..." UI. The best chance to create database and init data immediately after install, but how to do this, is there any broadcast? or is there any AndroidManifest attribute?

Android : Why Can Not Edit /init.rc On Adp1 With Firmware 1.1?

Mar 18, 2009

I flashed my adp1 to firmware 1.1 following the instruction from HTC. http://www.htc.com/www/support/android/adp.html But after that, I want to modify the /init.rc, after I remount the rootfs as writable, I can edit or replace the /init.rc file. But the file will roll back the original version after reboot the phone. Before I modify the /init.rc, I install the busybox to the phone, then I use 'cp" command to replace the /init.rc Any one can give me some advice?

Android :: How To Create Toast From Background Operation?

May 1, 2009

what is a good way to signal an error from a thread that is not the UI thread and you don't know which activity/handler is currently active? Can I somehow get eleto the current UI thread? Can I somehow use the MainLooper from the application context? I use notification for serious events where the user needs to take action, e.g. a login failed, but here I am looking for a transient notification with a toast and it would be ok if the toast is not seen in some cases.

Android :: Calling Method From Service Immediately

Sep 3, 2010

I'm pretty sure that android services are going to be the end of me.I have almost no hair left after the last few days.At first I was having a heck of a time getting the service to bind on an onclick of a button, got that straightened out from help here yesterday. Now I actually want the service to bind in the onCreate() method of the activity. That part is no problem, works as intended.My service is actually a socket service to connect TCP sockets to a socket server that I wrote.If I put the call to the method from the bound service mBoundService.StartSocketServer() inside a button click, bingo, works great. But I need this to fire up immediately when the activity loads, so directly under my bindService() call within my onCreate() method of the activity.When I place the call to start the socket inside my onCreate() I get a force-close.

This method (StartSocketServer()) spawns a new thread then opens the socket on that thread to my remote machine.I'm guessing that the problem lies with the new thread generation before the activity fully loads not sure.LogCat is fairly cryptic here. It does say something about thread attach failed, then shows an uncaught handler exception that has "Caused by: java.lang.NullPointerException" within it.Again, if I put this call to the method inside a button click, I"m in business, if it's in the onCreate() it fails. Is there some way inside an activity (presuming that my assumption is correct that it needs to fully load before spawning a new thread) to call the StartSocketServer() after it's loaded: ala body.onLoad() in html?

I have a background thread which queries for 1000 records at a time. After querying , when i call cursor.move To First(), the UI gets blocked until the operation is completed.This is very disturbing experience for user , especially if there are 10000 plus records.I use Thread.sleep in between after each 1000 records, As soon as cursor.move To First is called, UI blocks for 2 3 seconds. Am i missing anything here ?

Android :: New App Update Force Closes Immediately On Startup

Mar 31, 2009

This morning, we updated our app on AM; this was our first update since release of Android 1.1.

In testing, on the emulator and with the signed .apk installed on our handsets, everything appeared to be working fine; however, we uploaded to AM, selected the new CopyProtection option, and published. Wertago disappeared for about 30 minutes, and as soon as it reappeared, we downloaded, installed, and started. Immediately upon starting, we got a force close and were never able to get the app started at all.

We've seen some discussions about similar app behavior experienced by other developers, and there was mention of likely bugs in AM or in the Copy Protection scheme. Has this been confirmed by Google, is there any communication from them about a coming fix, or anything like that?

Here's a little detail about what we gather from the logcat output. Our app appears to fail upon attempting to open/create the database; the relevant line is:

tmpDatabase = instance.openOrCreateDatabase(SEARCH_DATABASE_NAME, Context.MODE_PRIVATE, null);

which throws the sqlite3_open_v2 error.

Android :: Process Dialog For Long Operation - Thread Object

May 29, 2010

In the code showed as below I create a process dialog for doing some long

public class main extends Activity { public ProgressDialog dialog = null;
final Handler handler = new Handler(){ public void handleMessage(Message msg){
dialog.dismiss(); TextView tv2 = (TextView) findViewById(R.id.TextView02);
tv2.setText("Done"); } };
Thread runlongjob = new Thread(){ public void run(){
SystemClock.sleep(4000); handler.sendEmptyMessage(0);
} };
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
} public void clickhandler(View v){ switch(v.getId()){

General :: Android 2.2.2 - Facebook App Login Failed / Operation Times Out

Android :: Water Damage / Immediately Powered On So Phone Now Useless

Aug 3, 2010

My phone dropped from my pocket into the toilet. It was in there for no longer than 5 seconds. I took out the battery and tried to dry everything off. In a panic I turned it back on to see if it would work. I wasn't thinking at all. It started to turn on, then the screen flickered and everything went black. I dried it out properly and it still won't turn on. I've plugged it into the charger, nothing. Is my phone now useless? My mom says will not buy me another phone until the contract is up, in over a year. Is there anything I can do? Or did I completely screw myself?
If my phone is gone, can I still save my contacts and/or pictures?
