When you run automated Android tests with Eclipse or from the command line, you get text output, which isn't good for reporting purposes. If you run a large set of test cases with automated build, the text report isn't very helpful. Fortunately, Android CTS generates test reports in XML with accompanying XSL to make it look nice in a browser. To run your own tests with Android CTS: Download Android CTS Make a new directory MyRepository under android-cts , alongside the existing repository directory. Copy host_config.xml from repository to MyRepository Create directory plans under MyRepository , add a test plan ( MyTests.xml ): <?xml version="1.0" encoding="UTF-8"?> <TestPla... Create directory testcases under MyRepository . Copy TestDeviceSetup.apk from repository/testcases to MyRepository/testcases Under MyRepository/testcases , create a test...

This is a list of built-in Android permission values: Permission Description Since API Level android.permission.ACCESS_CHECKIN_PROPERTIES Allows read/write access to the "properties" table in the checkin database, to change values that get uploaded. 1 android.permission.ACCESS_COARSE_LOCATION Allows an application to access coarse (e.g., Cell-ID, WiFi) location 1 android.permission.ACCESS_FINE_LOCATION Allows an application to access fine (e.g., GPS) location 1 android.permission.ACCESS_LOCATION_EXTRA_COMMANDS Allows an application to access extra location provider commands 1 android.permission.ACCESS_MOCK_LOCATION Allows an application to create mock location providers for testing 1 android.permission.ACCESS_NETWORK_STATE Allows applications to access information about networks 1 android.permission.ACCESS_SURFACE_FLINGER Allows an application to use SurfaceFlinger's low level features 1 android.permission.ACCESS_WIFI_STATE Allows applications to access information about Wi-Fi networks 1 android.permission.ACCOUNT_MANAGER Allows applications to call into AccountAuthenticators. Only the system can get this permission. 5 android.permission.AUTHENTICATE_ACCOUNTS...

From the Java Language Specification : Because some type information is erased during compilation, not all types are available at run time. Types that are completely available at run time are known as reifiable types . A type is reifiable if and only if one of the following holds: It refers to a non-generic type declaration. It is a parameterized type in which all type arguments are unbounded wildcards. It is a raw type. It is a primitive type. It is an array type whose component type is reifiable. For example: int is a reifiable type (primitive type) List is a reifiable type (raw type) List<?> is a reifiable type (parameterized type with unbound wildcards) List<String> is not a reifiable type (generic type) Class<?> is...

By default VirtualBox enables one network adapter ("Adapter 1") with NAT. Connection from the guest OS to the outside world works natually when the guest network adapter is assigned an IP address by the VirtualBox DHCP server. Use VBoxManage to see a list of DHCP servers: $ VBoxManage list dhcpservers NetworkName: H... The guest IP address is not visible from the outside world. If you need to access a server on the guest OS, you need to set up port forwarding in VirtualBox settings: Settings -> Network -> Adapter 1 -> Advanced -> Port Forwarding . Beware that on Linux/Unix, port forwarding may not work if you bind to a privileged port (port number < 1024) but you are not root. Bridged networking can be...

You should drop the generics notation when looking up a method by signature: import java.util.*; import java.lang.reflect.Me... In fact, Class.forName("java.util.List<java.lang.String>") fails with ClassNotFoundException ! However, all information about parameterized types are not lost at runtime. The Java reflection API does provide these methods to get information about parameterized types at runtime: Method.getGenericExceptionTypes Method.getGenericParameterTypes Method.getGenericReturnType for which the non-generic counterparts are: Method.getExceptionTypes Method.getParameterTypes Method.getReturnType

Fedora/Redhat List current status (for httpd): # chkconfig --list httpd Warning: this works only when one of /etc/rc runlevel .d/ K NN name or /etc/rc runlevel .d/ S NN name exists. It exports wrong status when both K and S scripts exist (in which case the status should be enabled). Enable sshd for run levels 2, 3, 5: # chkconfig --level 2,3,5 sshd on Disable sshd for run levels 2, 3, 5: # chkconfig --level 2,3,5 sshd off By default, the on and off options affect only runlevels 2, 3, 4, and 5. Debian/Ubuntu Add apache2 with defaults : # update-rc.d apache2 defaults If defaults is used then update-rc.d will make links to start the service in runlevels 2, 3, 4, 5 and to stop...

Facts: Dynamic proxy classes are generated by the Java runtime, from a list of interfaces given by the user. The generated proxy class implements all interfaces given by the user. The dynamic proxy class is not synthetic . The dynamic proxy class is useless without a user supplied InvocationHandler class, since there's only one constructor for the proxy class and it takes a InvocationHandler as parameter. Example code: import java.lang.reflect.Constructor; import ja... Output: Class: $Proxy0 isSynthetic: false Constructo...

The String.format() method provides versatile formatting capabilities. This tutorial tries to present these capabilities in a accessible manner. The format string A format string can contain zero, one, or more format specifiers . The general form of a format specifier is: %[argument_index$] [flags] [width] [.precision]co... where things in square brackets are optional, and conversion is a character indicating the conversion to be applied to the corresponding variable value. The only required characters in the format specifier is the percent sign % and the conversion character. A simple example: public static void simpleFormat() { System.out... The Argument index The argument index is specified by a number, terminated by the dollar sign $ . The same argument may be repeated multiple times in a format string. Unindexed...

When you run a Java application, the default place it looks for trusted certificates is $JAVA_HOME/jre/lib/security/cacerts , which is a keystore that contains a list of trusted CA certificates. You can use the keytool to list the certificates: C:\>keytool -list -keystore C:\jdk1.6.0_20\jre\lib... Simply hit return when asked for password, no password is required to list trusted certificates in a keystore.
