Little simple things where I lost some time finding out the resolution when developing for Android.

Emulator with PANIC error:

PANIC: Could not open: C:\Users\

This error happens all the time in windows environment. The most cause is because your username has some non-english characters like “éáç…”, and Android SDK uses your home folder in the operating system as a default to create the emulators.

Possible solution:

make a copy of the avd folder and configure the ini file to point to the new folder.

1. Go to the emulator folder (for instance: c:\users\usernamewithnonenglishlike-áéíç\.android\avd\)
2. Copy the “avd” folder to another folder without non-english characters (c:\myAvds\…")
   1. Don’t remove the original
3. In the original folder open the “init” file: (for instance: c:\users\usernamewithnonenglishlike-á\.android\avd\AVD_for_2_7in_QVGA.ini)
4. Change the path value to the new folder:
   1. path=newFolderWithoutNonEnglishCharacters\avd\AVD_for_2_7in_QVGA.avd
5. Start the emulator, it must work now!

PS: Another way is creating manually the AVD and place it in a custom folder:

android create avd -n myVirtualDevice -t 2 -p customfolder\avd

Associate the resource layout (xml file) with the Activity java class:

In the activity java file just add a line to link to the resource file.

Create your resource file or “design file” at res\layout\your_resource.xml

1. use only lowercase characters combined with numbers and “_”
1. In the Activity Java Class, in the “onCreate” method, use “setContentView(R.layout.your_resource) like the code below.

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        // Your xml resource file!

        setContentView(R.layout.resource_file);

    }

Can’t configure Android SDK in IntelliJ 12 when creating a new project

Intellij doesn’t have configured any jdk, so we must configure at least one!

1. Create the project without the Android SDK configured.
2. Add some jdk (1.5, 1.6, 1.7) in File->Project Structure
3. Then choose Android SDK for your project!
