To facilitate diagnostics while the app has been deployed, does Android provide any API to facilitate runtime logging? It would be ideal if the app could retrieve all the messages it wrote to the Logging System via the Log API functions.

While debugging, Log.d() or Log.e() methods come to LogCat, but how do I capture the runtime error or trace log on the Android device when it is not connected to the development environment ?
View 1 Replies View RelatedAs an additional anti-pirating strategy, I'd like to compute a checksum on my application at runtime. Since my app communicates with a back-end server, I can send the checksum with each message and the server can deny service to altered apps. Not a complete solution to piracy by any means, but a fairly easy way to raise the bar. Anyone know how an app can get access to it's load image at runtime?

View 1 Replies View RelatedI'm a bit into customizing my home screens to make it look like the ones on mycolorscreen.com and in those UCCW threads.
But there is one thing thats bugging me, and that is the use of app icons on the home screen. I dont like it, its too messy and too iOS'ish.
Some are replacing the app icons with other custom icons, or removes them completely, but i rarely see what i've been trying to do; to make custom icons that open a meny of apps (in one genre..)
Like one icon for music apps, and one for travel apps etc.
I have tried to fix this using tasker widgets, like this:
and when i click on the music icon, which is a tasker widget, it opens a tasker scene with a meny of 4 music apps:
This works pretty good, but i would like the tasker widget icons to be just icons, no subtext under the icon. There is no way in tasker to do this i think, i've tried to make a task with no name but it is simply not allowed.
I've also tried to make a uccw widget, but hotspots in uccw can open apps and shortcut, not a many of apps..
i know that i can make the launcher remove text under icons, but this doen not apply to my tasker widgets.
1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...
I want to know whenever someone is called, calls, smsed or smses. I figured for the calls I'd use the phone state change to trigger when I should check the CallLog provider again. I couldn't see any direct way of getting broadcasts from the CallLog. Did I miss it?
For SMSes I'm having more trouble. I'd like to know whenever and SMS is sent or received. Being able to receive STATUS_ON_SIM_READ and STATUS_ON_SIM_SENT would be great, but from what I've read in the Sms Manager that would depend on the sending application. I can't seem to find any evidence of a default one that android places when it sends. I also couldn't find an sms log provider or anything similar.
I have an app that is not in the market place (signed with a debug certificate), but would like to get crash log data, whenever my application crashes. Where can I find a log of why my app crashed?

View 2 Replies View RelatedIs there a way to access the default logs on the phone for purposes of uploading for debugging purposes? I'd like to be able to provide an "Upload Logs" button that allows the users of my app to upload their logs if they are encountering issues with the app. I know I can write my logs to my own file and provide an upload for that, but I like the context provided by the system logs interspersed with my log entries to understand what else is going on on the device when my app has issues.

public void addView(View child) {
child.setDrawingCacheEnabled(true);
child.setWillNotCacheDrawing(false);
child.setWillNotDraw(false);
child.buildDrawingCache();
if(child.getDrawingCache() == null) { //TODO Make this work!
Log.w("View", "View child's drawing cache is null");
}
setImageBitmap(child.getDrawingCache()); //TODO MAKE THIS WORK!!!
}
ALWAYS logs that the drawing cache is null, and sets the bitmap to null? Do I have to actually draw the view before the cache is set?
Is there an app that anyone knows of that allows you to restore your call logs from a WindowsMobile format, or is there a format that I can transfer them into to be able to restore them on Android?I searched and searched and could not find anything on this.I have many cases where there are SMS threads going back several years, some containing invoicing information, and I would like to not lose them.Same with the call logs the history may be important.I've transferred them from several WinMo phones in the past, so have built up quite a history.Don't worry about size or having to put them into a format, I can worry about that, but how can I load them into the Android?Is there maybe a forum or thread that has the file formats for Android? An application that "merges" the data into Android?
View 1 Replies View RelatedIs it by anyway possible to write to call logs database?? I mean i want to add selected numbers to the call history. I tried searching the tutorial on net but couldn't find any. Though 1 thing is for sure, IT CAN BE DONE. coz i have seen lots of applications online, which restore call logs, so i guess we can modify the call history database somehow(but how exactly is not clear with me).i already read this post but it happens to be posted a long time back.

View 12 Replies View RelatedI'm testing an android application with a long running service. I'm using Eclipse and have the usb cord hooked up with the phone sitting next to me. Since it's a long ongoing service, I do some other work while it runs and check the logcat logs every once in a while to make sure everything is going as expected.
A few minutes ago I noticed the phone rebooting. I think it's done this before as it would explain some weird application behavior. I quickly switched over to Eclipse to see what happened and found that the logcat log was (it seems) cleared during the reboot. So there's no log of whether my app crashed (and took down the phone?!) or if there was some other problem that took down the phone and my app.
Is there anyway I can find out what happened? This is a development phone, so I don't know if it reboots/crashes often on its own, or only while my app is running. It's a Motorola Droid running Firmware version 2.1-update1.
I have a simple app that I am building to get the hang of android's development environment - and things like click events, etc..
The app loads, and I am able to change the text in a textfield using a button handler. However, when I import the location class, and try to do a simple GPS call, the application crashes.
The problem is, everything looks good in Eclipse (error console) - and I'm not seeing any exceptions in the android emulator (DevTools). I have the logcat window open, but I haven't done anything in eclipse/code to send logcat anything (do I need to?)
Is there a better way to troubleshoot?
CODE:........................
Ok, so I wonder how to troubleshoot Android phone crashes, freezes, reboots, etc.
Maybe there are ways to troubleshoot these kind of events by looking at loggings to pinpoint the problem (like does a particular app cause this, or a hardware event, etc).
I see my HTC notices it recovered from an abnormal reset for instance, and asks to send logging to HTC HQ, so there seems to be ways that could tell more what is causing trouble?
I want to let the users send me the logs from the device i wonder how do i extract the logs in to a file on the device ?
