Når jeg har brukt telefonen litt og har lagt den fra meg for en kort periode før jeg tar den ibruk igjen, så hender det at den forteller meg at alt er i skjønneste orden… men hvor er Internett? Nettleseren har ikke skjønt det ennå, men det er faktisk ingen kobling mot det trådløse nettverket. Løsning: skru av og på trådløst på telefonen… og vente 30 sekunder.

Irriterende! Ellers grei telefon!

Synd det er så gammel Android på den, 4.1.2. Jeg kjører nyere Android på min gamle HTC Desire! Blir nok roota i løpet av sommeren! God sommer

Rooting Android

Rooted the phone using the unrevoked tool according to the steps of this article at theunlockr.com. This tool also runs on Linux. You might have to run it with sudo.

In addition to root the phone it also installs ClockworkMod Recovery which replaces the stock Android Recovery, to allow installing custom ROMs and provides some backup and restore functionality.

For me, no settings got lost in the rooting process, and I could use the phone just as normal afterwards. A rooted Android phone allows applications to run as the root user, so some applications might mess up your phone. This is required to install a custom Android system.

Remember backup

I used MyBackup to backup contacts, SMS and other settings. Used SMS Backup as a second backup for my SMS’s, which uploads the messages to my GMail account. To backup my apps I used MyBackup and Astro File Manager. Some backup applications requires a rooted phone, in that case you might backup what you can, then root the phone, and backup the rest before installing a new ROM.

Installing a custom ROM

The probably easiest way to install a custom ROM is to install the app ROM Manager from ClockworkMod. Personally I landed on CyanogenMod 7.0.3, running Android 2.3.3 Gingerbread.

The phone worked great after installing CyanogenMod, here with all the old apps back in

Factory reset is probably needed
Booting the phone after installing CyanogenMod failed, it got stuck while booting, only showing the CyanogenMod boot logo spinning forever. This might be caused by some bad settings from the stock Android that CyanogenMod didn’t like very much. Pulled the battery out and into place again, and started the phone holding back button to get to CyanogenMod Recovery boot loader, to factory reset, losing all settings and applications. The SD card is left untouched by this operatoin. Glad I backuped up the most important apps, settings, contacts and SMSes to begin with

Restore settings and applications

I tried to restore all the applications I previously had backed up, but applications that previously were installed on the SD card were restored to the internal storage, and failed when trying to move the app to SD card after restore. Had to uninstall those and install them once again from the Market. Application settings got lost in the process.

On most apps, it was just a matter to log in again to get back on track. I had to leave some apps after restore to keep the settings, especially apps that are not backed by online services, such as ColorNote. Uninstalling the app would erase the notes.

The good choice

So, did I like it? It’s OK. The onscreen keyboard is a little different, but now I got the æøå keys at least. Since I’m Norwegian, that makes sense I guess. There is no dictionary, but I haven’t searched Android Market for it yet, so perhaps I don’t miss it. I miss the second-click on the home button to get an overview of all the desktops, but it’s not a big deal.

Somehow all contacts in my Google Circles got lost the other night. I don’t know why, maybe because of some defect in a backup restore process or re-install of the Google+ app, or it might be a glitch at Google…

Since HTC has abandoned us Desire owners, even lay to us after promising us the 2.3 version, it was time to move on to something other. I guess I don’t need the Sense shit anymore. Now I can move Google apps to SD card, and even delete those I never used! CyanogenMod works great!

Jeg bestilte så en helt vanlig Micro USB-kabel på Komplett.no, henta den på Posten i dag og testa, og vips så dukka den opp på PC-en og telefonen ble satt i synkroniseringsmodus.

Husk å aktivere debugging på telefonen hvis du skal koble til med Android SDK adb.

When adding Google Maps to your Android application, make sure that the <uses -library>-tag is inside the <application>-tag of the manifest XML. This might be obvious, but I got this wrong and it took me a long time to figure out the real reason for the error.


<uses -library android:name="com.google.android.maps" />


Etter noen søk i Apple App Store fant jeg et program som heter Ubuntu One Contacts som kan synkronisere kontaktlista på iPhone opp mot Ubuntu One, en nettjeneste for å synkronisere filer mellom PC-er og dele filer og kataloger med andre.

Etter registrering på Ubuntu One, setter man opp innstillingene for mobiltelefon her, hvor du får tildelt brukernavn og passord, som skal brukes i Ubuntu One Contacts på iPhone. Dette er ikke samme innlogging som på nettsiden, hvor du logger inn med e-postadresse og selvvalgt passord.

Etter installering av Ubuntu One Contacts, skriver du inn brukernavnet og passordet du ble tildelt. Serverinnstillingene skal allerede være utfyllt med http://syncml.one.ubuntu.com. Du mottar også e-post med instruksjoner underveis. Gå så tilbake til forsiden av applikasjonen og trykk “Sync Contacts”. Hvis synkroniseringen fullfører uten feil skal du kunne se kontaktene dine på kontaktlista på Ubuntu One.

Sånn, da var den vanskelige halvparten av jobben gjort, å få ut dataene fra iPhone.

I Android Market søker du etter funambol og installerer Funambol Sync. Denne setter du opp med samme innstillinger som Ubuntu One Contacts på iPhone. Hvis du ikke husker brukernavn og passord står det i e-posten du har fått fra Ubuntu One.

Whoala, kontaktene er synkronisert.

OPPDATERT 18.01.2011
Jeg kan ikke lenger anbefale denne løsningen. Ubuntu ONE har stengt mobilsynkronisering for “basic”-kontoer.

Steve Guggenheimer i Microsoft tar frem “gratis” som argument for at mange hopper på Android-bølgen med tablets, tilsvarende da netbooks kom på markedet med Linux-operativsystemer, men Android har noe som ikke Linux på netbooks hadde, og det er Market – tilgjengelighet.

If you have been developing mobile applications for Android you have most likely seen some exceptions in the Eclipse debugger that you don’t understand, maybe not the tiniest bit. This mostly has to do with lack of experience with the API combined with the strict way that Android sets up views and restricts which threads that are allowed to draw and control the views, along with other concurrency issues.

Starting up your application in the emulated Android environment is not the fastest thing to do, so how can you debug your applications in a little more snappier way? – In short, I really don’t know.

What I want is a sane error message with a stack trace of my application code, but since I can’t get that, I have to debug my application in other ways.

Break points
By setting a breakpoint in your code on places where you think the bug might exist, you can step through your source code until the application fails.

The cons of this are that it is time consuming to do all the manual step by step operations, it’s a boring way of debugging and the exception message you get might not be understandable to you.

Logging
The Android API provides a Log class that can be used to log messages and exceptions. It took me some time to figure out how to read the log messages, but the Android Eclipse plugin provides a LogCat view.

To show the LogCat view in Eclipse, you go to “Window”, “Show View”, “Other …”, expand the “Android” category and then open the “LogCat” view.

Example output from the LogCat view.

01-09 16:56:52.069: ERROR/Listings(1064): Failed to get trip listings
01-09 16:56:52.069: ERROR/Listings(1064): java.lang.RuntimeException: Example of exception logging
01-09 16:56:52.069: ERROR/Listings(1064):     at no.ut.trip.Listings$ProgressThread.run(Listings.java:112)

The example above shows an error message on the first line, the exception class and message on the second line, with the stack trace on the following lines. Might be helpful.
