[SOLVED]Connect Nexus 7 and/or Galaxy Nexus to ubuntu

You want to develop on your new shiny Nexus 7 and

adb devices

keeps giving you

???????? device

oprn your rules file

gksu gedit /etc/udev/rules.d/51-android.rules

probably you will see following line (if you already configured your Galaxy nexus) If not add it to the file, just in case

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0666", OWNER="YOUR_USER_ID"

Now we should get the idVendor and idProduct from the Nexus 7. Connect it to your computer and

lsusb

you will see something like

Bus 001 Device 013: ID 18d1:4e42 Google Inc.

we need this two values

paste this string with proper values to 51-android.rules

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e42", MODE="0666", OWNER="YOUR_USER_ID"

Save the file. Do the

sudo service udev restart

Now run

adb devices

you should see your device

List of devices attached

Happy developing

[SOLVED] Android: Get an string array from an array.xml resource

Here you can see how to retrieve values from array.xml

Log.i("test",getImageQualityAsString(1));

array.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="image_export_list_preference">
        <item>480x320</item>
        <item>800x480</item>
        <item>1024x768</item>

    <string-array name="entryvalues_image_export_list_preference">
        <item>0</item>
        <item>1</item>
        <item>2</item>
    </string-array>
</resources>

Function:

private String getImageQualityAsString(int sizeItem){

        try {
            String[] bases = getResources().getStringArray(R.array.image_export_list_preference);

            return bases[sizeItem];

        } catch (Exception e) {

[SOLVED] Android: no adb on Suse linux or "???????????? no permissions"

You cant develop on your linux pc because you are getting something like this.

$ adb devices
List of devices attached 
   ????????????     no permissions

temporary solution - to restart adb server as root

$ su
$ adb kill-server
$ adb start-server
$ adb devices

add your device to devices list.
1) check your vendor ID

$ lsusb
  Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
  Bus 002 Device 044: ID 18d1:2d66  <- this is my mobile
  Bus 002 Device 004: ID 0451:2046 Texas Instruments, Inc. TUSB2046 Hub
  Bus 002 Device 003: ID 10d5:0001 Uni Class Technology Co., Ltd

In my case , for Nexus One, it is 18d1

2) now add lines in to "/etc/udev/rules.d/51-android.rules"

$ su
$ vim /etc/udev/rules.d/51-android.rules

now paste these lines with your values

SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", OWNER="%YOUR_USER%" GROUP="%YOUR_USER_GROUP%"

save your file.

now it should work...

install app to sd card in 2.2 (froyo)

-Go here
--http://developer.android.com/sdk/index.html
and get the SDK for your OS
-Once you download it, unzip it to its own folder, I put it off C:\
-Run the SDK Setup.exe
-Click available Packages, on left, I didn't know what was needed so I installed -EVERYTHING. Although I do suspect that we only need the USB driver, which is at the very bottom.
It will take forever to install.
After it's done installing, I Clicked on Installed Packages, and updated all.

Not done yet.
check that the phone is set up to allow debugging via USB (Settings⇒Applications⇒Development⇒USB debugging)
Plug in your phone
Windows will fail to install the driver.
Go in device manager and and update the newly Yellowed entry, the driver is in:
C:\android-sdk_r06-windows\android-sdk-windows\usb_driver
The driver should install

Start console: "Start"->"Run"->cmd->ENTER

> adb devices

if you see a serial number starting with an "H" that means you got things working, now do the following:

> adb shell pm setInstallLocation 2

This command will push ALL apps to your sd card, to revert back to saving apps to internal memory enter in:

> adb shell pm setInstallLocation 0

[SOLVED]Market Slowness and Accessibility on cyanogenmod's CM6 RC1

After upgrading to the latest Cyanogen I notices, that the Android Market is quiet slow and does not show my downloaded apps in the download section. 2 Fixes to repair this:

1) Take the following source and save in file named vending_preferences.xml

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<boolean name="local_db_sync_required" value="false" />
<int name="SERVER_VERSION" value="1000" />
<string name="vending_tos_version">1.0.0</string>
<long name="MARKET_LAST_HEARTBEAT_TIMESTAMP" value="1271657433127" />
<long name="last_sync_time" value="1271659724720" />
<long name="last_tickle_id" value="1271657514775" />
<int name="reconciled_version" value="1710" />
<boolean name="metadata_paid_apps_enabled" value="true" />
<string name="vending_backup_state">vending</string>
<string name="vending_tos_version">1.0.0</string>
</map>

Now push to /data/data/com.android.vending/shared_prefs/vending_preferences.xml :

adb push vending_preferences.xml /data/data/com.android.vending/shared_prefs/vending_preferences.xml

Next you do in a terminal window (device or via adb shell):

su
cd /data/data/com.android.vending/cache
rm *
reboot

[SOLVED]How customize/extend/ Spinner

You will need to take control over what goes into the ListView and
Spinner. I have not experimented with these techniques on Spinner, but
on ListView, you will need to override getView() (on ArrayAdapter) or
newView() and bindView() (on CursorAdapter).
Here is a free excerpt from one of my books that demonstrates the technique:

http://commonsware.com/Android/excerpt.pdf

In your case, you would use your Typeface object to update the font used
by the TextView widgets in your rows.

In principle, you could do this via a wrapping adapter -- this would be
more reusable but a bit slower. I have an AdapterWrapper base class here:

http://github.com/commonsguy/cwac-adapter

and some projects that use it here:

http://github.com/commonsguy/cwac-endless
http://github.com/commonsguy/cwac-thumbnail

You also need to override getDropDownView().
