Android- Using DexClassLoader to load apk file

Question

I\'ve hit a bit of a wall. Any help would be appreciated. I have an app that I want to use DexClassLoader to load another apk file.

Here is my code:

Answer 1

Try using Android's PathClassLoader:

    String packagePath = "com.mypackage";
    String classPath = "com.mypackage.ExternalClass";

    String apkName = null;
    try {
        apkName = getPackageManager().getApplicationInfo(packagePath,0).sourceDir;
    } catch (PackageManager.NameNotFoundException e) {
        // catch this
    }

    // add path to apk that contains classes you wish to load
    String extraApkPath = apkName + ":/path/to/extraLib.apk" 

    PathClassLoader pathClassLoader = new dalvik.system.PathClassLoader(
            apkName,
            ClassLoader.getSystemClassLoader());

    try {
        Class handler = Class.forName(classPath, true, pathClassLoader);
    } catch (ClassNotFoundException e) {
        // catch this
    }
