Detailed Description

This class bridges the C++ and Java worlds of the Android service by providing the handles into the Android/Java world needed by the C++ components of the PAL layer.

Member Function Documentation

jobject Android::getClassLoader ( )
static

Acquire a global reference to a Java ClassLoader that will be capable of loading PAL-layer classes (the reference will be valid until the application terminates).

Returns
The java.lang.ClassLoader global reference.

+ Here is the caller graph for this function:

void Android::setContext ( jobject  contextRef)
static

Provide a reference to the Android Context object which provides the access rights to the system, such as Bluetooth or USB access. The android.content.Context object reference provided may be of any scope, it will be copied into a global reference, which can be accessed later using getContext().

This function must be called exactly once during initialization of the system before the PAL layer modules are initialized, as the modules in the PAL layer may depend on this reference being available during initialization.
