[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
015d172c98280c0b device

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>

        <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];

[SOLVED] PHP: Why 2 !=2 aka "never compare floating point numbers for equality"

“never compare floating point numbers for equality”.

The reason (19.6*100) !== (double)1960, is because inside a computer they are not equal.

Try this:

<?php

printf("%.15f", (19.6*100));

?>

Outputs: 1960.000000000000227 (not 1960 as somewhat expected)

If comparison is required a few options come to mind (other than BCMath):

1) Round numbers before comparison:

<?php

$sig_figs = 5;
echo (round((19.6*100), $sig_figs) !== round((double)1960, $sig_figs)) ? 'not equal' : 'equal';

?>

Outputs: equal

[SOLVED] Android: Set Admob programmatically into test mode

(6) When integrating AdMob ads into your application it is recommended to use test mode. In test mode test, ads are always returned.

Test mode is enabled on a per-device basis. To enable test mode for a device, first request an ad, then look in LogCat for a line like the following:

  To get test ads on the emulator use AdManager.setTestDevices...

Once you have the device ID you can enable test mode by calling AdManager.setTestDevices:

  AdManager.setTestDevices( new String[] {                 
     AdManager.TEST_EMULATOR,             // Android emulator
     "E83D20734F72FB3108F104ABC0FFC738",  // My T-Mobile G1 Test Phone

[SOLVED] Set Screen Orientation Programmatically

There are times where you need to ensure that your application is displayed only in a certain orientation. For example, suppose you are writing a game that should only be viewed in landscape mode. In this case, you can programmatically force a change in orientation using the setRequestOrientation() method of the Activity class:

package net.learn2develop.OrientationAware;
import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;

public class Orientation extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //---change to landscape mode---
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }
}

To change to portrait mode, use the ActivityInfo.SCREEN_ORIENTATION_PORTRAIT constant:

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
