com.google.dexmaker.DexMaker.generateAndLoad()

Generates a dex file and loads its types into the current process.

Picking a dex cache directory

The {@code dexCache} should be an application-private directory. Ifyou pass a world-writable directory like {@code /sdcard} a malicious appcould inject code into your process. Most applications should use this:

    {@code File dexCache = getApplicationContext().getDir("dx", Context.MODE_PRIVATE);}

If the {@code dexCache} is null, this method will consult the {@code dexmaker.dexcache} system property. If that exists, it will be used forthe dex cache. If it doesn't exist, this method will attempt to guess the application's private data directory as a last resort. If that fails, this method will fail with an unchecked exception. You can avoid the exception by either providing a non-null value or setting the system property. @param parent the parent ClassLoader to be used when loading ourgenerated types @param dexCache the destination directory where generated and optimizeddex files will be written. If null, this class will try to guess the application's private data dir.

        code.op(BinaryOp.ADD, result, c, d);
        code.returnValue(result);

        ClassLoader loader = dexMaker.generateAndLoad(
                FibonacciMaker.class.getClassLoader(), getDataDirectory());


        Class<?> fibonacciClass = loader.loadClass("com.google.dexmaker.examples.Fibonacci");
        Method fibMethod = fibonacciClass.getMethod("fib", int.class);
        System.out.println(fibMethod.invoke(null, 8));

        dexMaker.declare(helloWorld, "HelloWorld.generated", Modifier.PUBLIC, TypeId.OBJECT);
        generateHelloMethod(dexMaker, helloWorld);


        // Create the dex file and load it.
        File outputDir = new File(".");
        ClassLoader loader = dexMaker.generateAndLoad(HelloWorldMaker.class.getClassLoader(),
                outputDir);
        Class<?> helloWorldClass = loader.loadClass("HelloWorld");


        // Execute our newly-generated code in-process.
        helloWorldClass.getMethod("hello").invoke(null);
